## Introduction

This chart bootstraps an [Apache Airflow](https://github.com/bitnami/containers/tree/main/bitnami/airflow) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/airflow
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The command deploys Apache Airflow on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Executors

Airflow supports different [Executors](https://www.astronomer.io/docs/learn/airflow-executors-explained) and this Helm chart provides support for several of them. You can choose the executor you want to use by setting the `executor` parameter.

#### CeleryExecutor

The Celery executor (default one) uses a message queue system (Redis&reg; in this case) to coordinate tasks between pre-configured workers.

#### KubernetesExecutor

The Kubernetes executor creates a new worker pod for every task instance using the `pod_template.yaml` that you can find at [templates/config/configmap.yaml](https://github.com/bitnami/charts/blob/main/bitnami/airflow/templates/config/configmap.yaml). This template can be overwritten using `worker.podTemplate`. To enable `KubernetesExecutor` you can set the following parameters:

```console
executor=KubernetesExecutor
rbac.create=true
serviceAccount.create=true
redis.enabled=false
```

> NOTE: Redis&reg; is not needed to be deployed when using KubernetesExecutor so you can disable it using `redis.enabled=false`.

### CeleryKubernetesExecutor

The CeleryKubernetesExecutor (introduced in Airflow 2.0) is a combination of both the Celery and the Kubernetes executors. Tasks will be executed using Celery by default, but those tasks that require it can be executed in a Kubernetes pod using the 'kubernetes' queue.

#### LocalExecutor

The Local executor runs tasks by spawning processes in the Scheduler pods. To enable `LocalExecutor` set the following parameters.

```console
executor=LocalExecutor
redis.enabled=false
```

### LocalKubernetesExecutor

The LocalKubernetesExecutor (introduced in Airflow 2.3) is a combination of both the Local and the Kubernetes executors. Tasks will be executed in the scheduler by default, but those tasks that require it can be executed in a Kubernetes pod using the 'kubernetes' queue.

#### SequentialExecutor

This executor will only run one task instance at a time in the Scheduler pods. For production use case, please use other executors. To enable `SequentialExecutor` set the following parameters.

```console
executor=SequentialExecutor
redis.enabled=false
```

### Scaling worker pods

Sometime when using large workloads a fixed number of worker pods may make task to take a long time to be executed. This chart provide two ways for scaling worker pods.

- If you are using `KubernetesExecutor` auto scaling pods would be done by the Scheduler without adding anything more.
- If you are using `SequentialExecutor` you would have to enable `worker.autoscaling` to do so, please, set the following parameters. It will use autoscaling by default configuration that you can change using `worker.autoscaling.replicas.*` and `worker.autoscaling.targets.*`.

```console
worker.autoscaling.enabled=true
worker.resources.requests.cpu=200m
worker.resources.requests.memory=250Mi
```

### Generate a Fernet key

A Fernet key is required in order to encrypt password within connections. The Fernet key must be a base64-encoded 32-byte key.

Learn how to generate one [here](https://airflow.apache.org/docs/apache-airflow/stable/security/secrets/fernet.html#generating-fernet-key).

### Generate a Secret key

Secret key used to run your Flask app. It should be as random as possible.

> Note: when running multiple Webserver instances, make sure all of them use the same secret key. Otherwise you may face the error "CSRF session token is missing".

### Load DAG files

There are two different ways to load your custom DAG files into the Airflow chart. All of them are compatible so you can use more than one at the same time.

#### Option 1: Specify an existing config map

You can manually create a config map containing all your DAG files and then pass the name when deploying Airflow chart. For that, you can set the parameters below:

```console
dags.enabled=true
dags.existingConfigmap=my-dags-configmap
```

#### Option 2: Get your DAG files from a git repository

You can store all your DAG files on GitHub repositories and then clone to the Airflow pods with an initContainer. The repositories will be periodically updated using a sidecar container. In order to do that, you can deploy airflow with the following options:

> Note: When enabling git synchronization, an init container and sidecar container will be added for all the pods running airflow, this will allow scheduler, worker and web component to reach dags if it was needed.

```console
dags.enabled=true
dags.repositories[0].repository=https://github.com/USERNAME/REPOSITORY
dags.repositories[0].name=REPO-IDENTIFIER
dags.repositories[0].branch=master
```

If you use a private repository from GitHub, a possible option to clone the files is using a [Personal Access Token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) and using it as part of the URL: `https://USERNAME:PERSONAL_ACCESS_TOKEN@github.com/USERNAME/REPOSITORY`. Alternatively, you can clone the repository using SSH, to do so, you can set your private SSH Key setting the `dags.sshKey` parameter or use an existing secret containing your private SSH key setting the `dags.existingSshKeySecret` and `dags.existingSshKeySecretKey` parameters.

### Loading Plugins

You can load plugins into the chart by specifying a git repository containing the plugin files. The repository will be periodically updated using a sidecar container. In order to do that, you can deploy airflow with the following options:

> Note: When enabling git synchronization, an init container and sidecar container will be added for all the pods running airflow, this will allow scheduler, worker and web component to reach plugins if it was needed.

```console
plugins.enabled=true
plugins.repositories[0].repository=https://github.com/teamclairvoyant/airflow-rest-api-plugin.git
plugins.repositories[0].branch=v1.0.9-branch
plugins.repositories[0].path=plugins
```

### Install extra python packages

This chart allows you to mount volumes using `extraVolumes` and `extraVolumeMounts` in every component (web, scheduler, worker). Mounting a `requirements.txt` using these options to `/bitnami/python/requirements.txt` will execute `pip install -r /bitnami/python/requirements.txt` on container start.

### Existing Secrets

You can use an existing secret to configure your Airflow auth, external Postgres, and external Redis&reg; passwords:

```console
postgresql.enabled=false
externalDatabase.host=my.external.postgres.host
externalDatabase.user=bn_airflow
externalDatabase.database=bitnami_airflow
externalDatabase.existingSecret=all-my-secrets
externalDatabase.existingSecretPasswordKey=postgresql-password

redis.enabled=false
externalRedis.host=my.external.redis.host
externalRedis.existingSecret=all-my-secrets
externalRedis.existingSecretPasswordKey=redis-password

auth.existingSecret=all-my-secrets
```

The expected secret resource looks as follows:

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: all-my-secrets
type: Opaque
data:
  airflow-password: "Smo1QTJLdGxXMg=="
  airflow-fernet-key: "YVRZeVJVWnlXbU4wY1dOalVrdE1SV3cxWWtKeFIzWkVRVTVrVjNaTFR6WT0="
  airflow-secret-key: "a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08="
  postgresql-password: "cG9zdGdyZXMK"
  redis-password: "cmVkaXMK"
```

This is useful if you plan on using [Bitnami's sealed secrets](https://github.com/bitnami-labs/sealed-secrets) to manage your passwords.

Alternatively, you can also use a SQL connection string to connect to an external database. This can be done by:

- Setting the `externalDatabase.sqlConnection` parameter:

```console
postgresql.enabled=false
externalDatabase.sqlConnection=postgresql://user:password@host:port/dbname
```

- Or via the `externalDatabase.existingSecret` and `externalDatabase.existingSecretSqlConnectionKey` parameters:

```console
postgresql.enabled=false
externalDatabase.existingSecret=db-secret
externalDatabase.existingSecretSqlConnectionKey=sql-connection
```

### Database setup

By default, this chart setups the database (init or migrate the schema) and creates the admin user using a K8s job that is created when the chart release is installed or upgraded, and deleted once it succeeds. This job uses [Chart hooks](https://helm.sh/docs/topics/charts_hooks), so it won't be deleted if you're using Helm exclusively for its rendering capabilities (e.g. when using ArgoCD or FluxCD).

Alternatively, you can disable this behavior by setting the `setupDBJob.enabled` parameter to `false`. In this case, the database setup and admin user creation will be done during the Webserver startup.

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### Prometheus metrics

This chart can be integrated with Prometheus by setting `metrics.enabled` true. This will deploy a sidecar container with [airflow-exporter](https://github.com/PBWebMedia/airflow-prometheus-exporter) in all Airflow pods and a `metrics` service, which can be configured under the `metrics.service` section. This `metrics` service will be have the necessary annotations to be automatically scraped by Prometheus.

#### Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the [Bitnami Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/prometheus) or the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) to easily have a working Prometheus in your cluster.

#### Integration with Prometheus Operator

The chart can deploy `ServiceMonitor` objects for integration with Prometheus Operator installations. To do so, set the value `metrics.serviceMonitor.enabled=true`. Ensure that the Prometheus Operator `CustomResourceDefinitions` are installed in the cluster or it will fail with the following error:

```text
no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"
```

Install the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) for having the necessary CRDs and the Prometheus Operator.

### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application.

To enable Ingress integration, set `ingress.enabled` to `true`.

The most common scenario is to have one host name mapped to the deployment. In this case, the `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host. However, it is also possible to have more than one host. To facilitate this, the `ingress.extraHosts` parameter (if available) can be set with the host names specified as an array. The `ingress.extraTLS` parameter (if available) can also be used to add the TLS configuration for extra hosts.

> NOTE: For each host specified in the `ingress.extraHosts` parameter, it is necessary to set a name, path, and any annotations that the Ingress controller should know about. Not all annotations are supported by all Ingress controllers, but [this annotation reference document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md) lists the annotations supported by many popular Ingress controllers.

Adding the TLS parameter (where available) will cause the chart to generate HTTPS URLs, and the application will be available on port 443. The actual TLS secrets do not have to be generated by this chart. However, if TLS is enabled, the Ingress record will not work until the TLS secret exists.

[Learn more about Ingress controllers](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/).

### HTTPS for Webserver

By default, this chart assumes TLS is managed by the Ingress Controller and terminates the TLS connection in the Ingress Controller. This can be done by setting `ingress.enabled` and `ingress.tls` parameters to `true` as explained in the section above. However, it is possible to configure TLS encryption for the Airflow Webserver directly by setting the `web.tls.enabled` parameter to `true`.

It is necessary to create a secret containing the TLS certificates and pass it to the chart via the `web.tls.existingSecret` parameter. The secret should contain a `tls.crt` and `tls.key` keys including the certificate and key files respectively. For example:

```console
kubectl create secret generic web-tls-secret --from-file=./tls.crt --from-file=./tls.key
```

You can manually create the required TLS certificates or relying on the chart auto-generation capabilities. The chart supports two different ways to auto-generate the required certificates:

- Using Helm capabilities. Enable this feature by setting `web.tls.autoGenerated.enabled` to `true` and `web.tls.autoGenerated.engine` to `helm`.
- Relying on CertManager (please note it's required to have CertManager installed in your K8s cluster). Enable this feature by setting `web.tls.autoGenerated.enabled` to `true` and `web.tls.autoGenerated.engine` to `cert-manager`. Please note it's supported to use an existing Issuer/ClusterIssuer for issuing the TLS certificates by setting the `web.tls.autoGenerated.certManager.existingIssuer` and `web.tls.autoGenerated.certManager.existingIssuerKind` parameters.

### Sidecars

If additional containers are needed in the same pod as Apache Airflow (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter.

```yaml
sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234
```

If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:

```yaml
service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311
```

If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

## Persistence

The Bitnami Airflow chart relies on the PostgreSQL chart persistence. This means that Airflow does not persist anything.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
               --set auth.username=my-user \
               --set auth.password=my-passsword \
               --set auth.fernetKey=my-fernet-key \
               --set auth.secretKey=my-secret-key \
               oci://REGISTRY_NAME/REPOSITORY_NAME/airflow
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the credentials to access the Airflow web UI.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/airflow
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/airflow/values.yaml)

## Upgrading

### To 21.0.0

This major version uses a single container image ([`bitnami/airflow`](https://github.com/bitnami/containers/tree/main/bitnami/airflow) by default) to run every Airflow component (Webserver, Scheduler and Worker) so `bitnami/airflow-scheduler` and `bitnami/airflow-worker` images are no longer necessary. Also, operations to load custom DAGs and plugins via init containers also use this same image so `bitnami/git` and `bitnami/os-shell` are no longer necessary either. These changes implies several simplifications in the chart values:

- New `image.*` parameters are introduced to configure the container image used to run the Airflow components.
- `web.image.*`, `scheduler.image.*` and `worker.image.*` parameters are removed.
- `dags.image.*` and `git.image.*` parameters are removed.

Some other simplifications are introduced around adding custom DAGs and plugins:

- `dags.*` and `git.dags.*` parameters are merged into a single `dags.*` parameter.
- `git.plugins.*` parameter are renamed to `plugins.*`.
- `git.clone.*` and `git.sync.` parameters are now available under `defaultInitContainers.loadDAGsPlugins.*` and `defaultSidecars.syncDAGsPlugins.*`, respectively.

No upgrades issues are expected when upgrading from `20.x.x` if DAGs and plugins related parameters are properly adapted as described above.

### To 20.0.0

This major updates the PostgreSQL subchart to its newest major, 16.0.0, which uses PostgreSQL 17.x.  Follow the [official instructions](https://www.postgresql.org/docs/17/upgrading.html) to upgrade to 17.x.

### To 19.0.0

This major updates the Redis&reg; subchart to its newest major, 20.0.0. [Here](https://github.com/bitnami/charts/tree/main/bitnami/redis#to-2000) you can find more information about the changes introduced in that version.

### To 18.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 17.0.0

This major release bumps the PostgreSQL chart version to [14.x.x](https://github.com/bitnami/charts/pull/22750); no major issues are expected during the upgrade.

### To 16.0.0

This major updates the PostgreSQL subchart to its newest major, 13.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1300) you can find more information about the changes introduced in that version.

### To 15.0.0

This major updates the Redis&reg; subchart to its newest major, 18.0.0. [Here](https://github.com/bitnami/charts/tree/main/bitnami/redis#to-1800) you can find more information about the changes introduced in that version.

NOTE: Due to an error in our release process, Redis&reg;' chart versions higher or equal than 17.15.4 already use Redis&reg; 7.2 by default.

### To 14.0.0

This major updates the PostgreSQL subchart to its newest major, 12.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1200) you can find more information about the changes introduced in that version.

### To 13.0.0

This major update the Redis&reg; subchart to its newest major, 17.0.0, which updates Redis&reg; from its version 6.2 to the latest 7.0.

### To 12.0.0

This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository. Additionally updates the PostgreSQL & Redis subcharts to their newest major 11.x.x and 16.x.x, respectively, which contain similar changes.

- *auth.forcePassword* parameter is deprecated. The new version uses Helm's lookup functionalities and forcing passwords isn't required anymore.
- *config* and *configurationConfigMap* have been renamed to *configuration* and *existingConfigmap*, respectively.
- *dags.configMap* and *web.configMap* have been renamed to *dags.existingConfigmap* and *web.existingConfigmap*, respectively.
- *web.containerPort* and *worker.port* have been regrouped under the *web.containerPorts* and *worker.containerPorts* maps, respectively.
- *web.podDisruptionBudget*, *scheduler.podDisruptionBudget* and *worker.podDisruptionBudget* maps have been renamed to *web.pdb*, *scheduler.pdb* and *worker.pdb*, respectively.
- *worker.autoscaling.replicas.min*, *worker.autoscaling.replicas.max*, *worker.autoscaling.targets.cpu* and *worker.autoscaling.targets.memory* have been renamed to *worker.autoscaling.minReplicas*, *worker.autoscaling.maxReplicas*, *worker.autoscaling.targetCPU* and *.Values.worker.autoscaling.targetMemory*, respectively.
- *service.port* and *service.httpsPort* have been regrouped under the *service.ports* map.
- *ingress* map is completely redefined.
- *metrics.service.port* has been regrouped under the *metrics.service.ports* map.
- Support for Network Policies is dropped and it'll be properly added in the future.
- The secret keys *airflow-fernetKey* and *airflow-secretKey* were renamed to *airflow-fernet-key* and *airflow-secret-key*, respectively.

#### How to upgrade to version 12.0.0

To upgrade to *12.0.0* from *11.x*, it should be done reusing the PVC(s) used to hold the data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is *airflow* and the release namespace *default*):

> NOTE: Please, create a backup of your database before running any of those actions.

1. Obtain the credentials and the names of the PVCs used to hold the data on your current release:

```console
        export AIRFLOW_PASSWORD=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-password}" | base64 --decode)
        export AIRFLOW_FERNET_KEY=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-fernetKey}" | base64 --decode)
        export AIRFLOW_SECRET_KEY=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-secretKey}" | base64 --decode)
        export POSTGRESQL_PASSWORD=$(kubectl get secret --namespace default airflow-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
        export REDIS_PASSWORD=$(kubectl get secret --namespace default airflow-redis -o jsonpath="{.data.redis-password}" | base64 --decode)
        export POSTGRESQL_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=airflow,app.kubernetes.io/name=postgresql,role=primary -o jsonpath="{.items[0].metadata.name}")
```

1. Delete the Airflow worker & PostgreSQL statefulset (notice the option *--cascade=false*) and secrets:

```console
        kubectl delete statefulsets.apps --cascade=false airflow-postgresql
        kubectl delete statefulsets.apps --cascade=false airflow-worker
        kubectl delete secret postgresql --namespace default
        kubectl delete secret airflow --namespace default
```

1. Upgrade your release using the same PostgreSQL version:

```console
        CURRENT_PG_VERSION=$(kubectl exec airflow-postgresql-0 -- bash -c 'echo $BITNAMI_IMAGE_VERSION')
        helm upgrade airflow bitnami/airflow \
          --set loadExamples=true \
          --set web.baseUrl=http://127.0.0.1:8080 \
          --set auth.password=$AIRFLOW_PASSWORD \
          --set auth.fernetKey=$AIRFLOW_FERNET_KEY \
          --set auth.secretKey=$AIRFLOW_SECRET_KEY \
          --set postgresql.image.tag=$CURRENT_VERSION \
          --set postgresql.auth.password=$POSTGRESQL_PASSWORD \
          --set postgresql.persistence.existingClaim=$POSTGRESQL_PVC \
          --set redis.password=$REDIS_PASSWORD \
          --set redis.cluster.enabled=true
```

1. Delete the existing Airflow worker & PostgreSQL pods and the new statefulset will create a new one:

```console
        kubectl delete pod airflow-postgresql-0
        kubectl delete pod airflow-worker-0
```

### To 11.0.0

This major update the Redis&reg; subchart to its newest major, 15.0.0. [Here](https://github.com/bitnami/charts/tree/main/bitnami/redis#to-1500) you can find more info about the specific changes.

### To 10.0.0

This major updates the Redis&reg; subchart to it newest major, 14.0.0, which contains breaking changes. For more information on this subchart's major and the steps needed to migrate your data from your previous release, please refer to [Redis&reg; upgrade notes.](https://github.com/bitnami/charts/tree/main/bitnami/redis#to-1400).

### To 7.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL. The following changes were introduced in this version:

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running *helm dependency update*, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Chart.
- Several parameters were renamed or disappeared in favor of new ones on this major version:
  - The image objects have been moved to its corresponding component object, e.g: *workerImage* now is located at *worker.image*.
  - The prefix *airflow* has been removed. Therefore, parameters prefixed with *airflow* are now at root level, e.g. *airflow.loadExamples* now is *loadExamples* or *airflow.worker.resources* now is *worker.resources*.
  - Parameters related to the *git* features has completely been refactored:
    - They have been regrouped under the *git* map.
    - *airflow.cloneDagsFromGit* no longer exists, instead you must use *git.dags* and *git.dags.repositories* has been introduced that will add support for multiple repositories.
    - *airflow.clonePluginsFromGit* no longer exists, instead you must use *git.plugins*. *airflow.clonePluginsFromGit.repository*, *airflow.clonePluginsFromGit.branch* and *airflow.clonePluginsFromGit.path* have been removed in favour of *git.dags.repositories*.
  - Liveness and readiness probe have been separated by components *airflow.livenessProbe.** and *airflow.readinessProbe* have been removed in favour of *web.livenessProbe*, *worker.livenessProbe*, *web.readinessProbe* and *worker.readinessProbe*.
  - *airflow.baseUrl* has been moved to *web.baseUrl*.
  - Security context has been migrated to the bitnami standard way so that *securityContext* has been divided into *podSecurityContext* that will define the **fsGroup** for all the containers in the pod and *containerSecurityContext* that will define the user id that will run the main containers.
  - *./files/dags/*.py* will not be include in the deployment any more.
- Additionally updates the PostgreSQL & Redis subcharts to their newest major 10.x.x and 11.x.x, respectively, which contain similar changes.

#### Considerations when upgrading to this version

- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version does not support Helm v2 anymore.
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3.

#### How to upgrade to version 7.0.0

To upgrade to *7.0.0* from *6.x*, it should be done reusing the PVC(s) used to hold the data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is *airflow* and the release namespace *default*):

> NOTE: Please, create a backup of your database before running any of those actions.

1. Obtain the credentials and the names of the PVCs used to hold the data on your current release:

```console
        export AIRFLOW_PASSWORD=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-password}" | base64 --decode)
        export AIRFLOW_FERNET_KEY=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-fernetKey}" | base64 --decode)
        export AIRFLOW_SECRET_KEY=$(kubectl get secret --namespace default airflow -o jsonpath="{.data.airflow-secretKey}" | base64 --decode)
        export POSTGRESQL_PASSWORD=$(kubectl get secret --namespace default airflow-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
        export REDIS_PASSWORD=$(kubectl get secret --namespace default airflow-redis -o jsonpath="{.data.redis-password}" | base64 --decode)
        export POSTGRESQL_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=airflow,app.kubernetes.io/name=postgresql,role=primary -o jsonpath="{.items[0].metadata.name}")
```

1. Delete the Airflow worker & PostgreSQL statefulset (notice the option *--cascade=false*):

```console
        kubectl delete statefulsets.apps --cascade=false airflow-postgresql
        kubectl delete statefulsets.apps --cascade=false airflow-worker
```

1. Upgrade your release:

> NOTE: Please remember to migrate all the values to its new path following the above notes, e.g: `airflow.loadExamples` -> `loadExamples` or `airflow.baseUrl=http://127.0.0.1:8080` -> `web.baseUrl=http://127.0.0.1:8080`.

```console
        helm upgrade airflow bitnami/airflow \
          --set loadExamples=true \
          --set web.baseUrl=http://127.0.0.1:8080 \
          --set auth.password=$AIRFLOW_PASSWORD \
          --set auth.fernetKey=$AIRFLOW_FERNET_KEY \
          --set auth.secretKey=$AIRFLOW_SECRET_KEY \
          --set postgresql.postgresqlPassword=$POSTGRESQL_PASSWORD \
          --set postgresql.persistence.existingClaim=$POSTGRESQL_PVC \
          --set redis.password=$REDIS_PASSWORD \
          --set redis.cluster.enabled=true
```

1. Delete the existing Airflow worker & PostgreSQL pods and the new statefulset will create a new one:

```console
        kubectl delete pod airflow-postgresql-0
        kubectl delete pod airflow-worker-0
```
