Introduction¶

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps an Mastodon Deployment in a Kubernetes cluster using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm charts in clusters.

Learn more about the default configuration of the chart.

Prerequisites¶

• Kubernetes 1.19+
• Helm 3.2.0+
• PV provisioner support in the underlying infrastructure

Installing the Chart¶

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

helm install my-release bitnami/mastodon

The command deploys Mastodon on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart¶

To uninstall/delete the my-release deployment:

helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Parameters¶

Init Container Parameters¶

Other Parameters¶

External Redis parameters¶

External S3 parameters¶

External elasticsearch configuration¶

Redis sub-chart parameters¶

PostgreSQL chart configuration¶

MinIO® chart parameters¶

Elasticsearch chart configuration¶

Apache chart configuration¶

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

helm install my-release \
  --set adminUsername=admin \
  --set adminPassword=password \
    bitnami/mastodon

The above command sets the mastodon administrator account username and password to admin and password respectively.

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 above parameters can be provided while installing the chart. For example,

helm install my-release -f values.yaml bitnami/mastodon

Tip: You can use the default values.yaml

Configuration and installation details¶

Rolling VS Immutable tags¶

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.

External database support¶

You may want to have Mastodon connect to an external database rather than installing one inside your cluster. Typical reasons for this are to use a managed database service, or to share a common database server for all your applications. To achieve this, the chart allows you to specify credentials for an external database with the externalDatabase parameter. You should also disable the MongoDB installation with the postgresql.enabled option. Here is an example:

postgresql.enabled=false
externalDatabase.host=myexternalhost
externalDatabase.user=myuser
externalDatabase.password=mypassword
externalDatabase.database=mydatabase
externalDatabase.port=5432

External redis support¶

You may want to have mastodon connect to an external redis rather than installing one inside your cluster. Typical reasons for this are to use a managed redis service, or to share a common redis server for all your applications. To achieve this, the chart allows you to specify credentials for an external redis with the externalRedis parameter. You should also disable the Redis installation with the redis.enabled option. Here is an example:

redis.enabled=false
externalRedis.host=myexternalhost
externalRedis.password=mypassword
externalRedis.port=6379

External elasticsearch support¶

You may want to have mastodon connect to an external elasticsearch rather than installing one inside your cluster. Typical reasons for this are to use a managed elasticsearch service, or to share a common elasticsearch server for all your applications. To achieve this, the chart allows you to specify credentials for an external elasticsearch with the externalElasticsearch parameter. You should also disable the Redis installation with the elasticsearch.enabled option. Here is an example:

elasticsearch.enabled=false
externalElasticsearch.host=myexternalhost
externalElasticsearch.password=mypassword
externalElasticsearch.port=9200

External S3 support¶

You may want to have mastodon connect to an external storage streaming rather than installing MiniIO(TM) inside your cluster. To achieve this, the chart allows you to specify credentials for an external storage streaming with the externalS3 parameter. You should also disable the MinIO(TM) installation with the minio.enabled option. Here is an example:

minio.enabled=false
externalS3.host=myexternalhost
exterernalS3.accessKeyID=accesskey
externalS3.accessKeySecret=secret

Ingress¶

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as nginx-ingress-controller or contour you can utilize the ingress controller to serve your application.

To enable Ingress integration, set apache.ingress.enabled to true. The apache.ingress.hostname property can be used to set the host name. The apache.ingress.tls parameter can be used to add the TLS configuration for this host. It is also possible to have more than one host, with a separate TLS configuration for each host. Learn more about configuring and using Ingress.

TLS secrets¶

The chart also facilitates the creation of TLS secrets for use with the Ingress controller, with different options for certificate management. Learn more about TLS secrets.

Persistence¶

The Bitnami mastodon image stores the mastodon data and configurations at the /bitnami path of the container. Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.

Additional environment variables¶

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the extraEnvVars property inside the web, streaming and sidekiq sections.

streaming:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the extraEnvVarsCM or the extraEnvVarsSecret values inside the web, streaming and sidekiq sections.

Sidecars¶

If additional containers are needed in the same pod as mastodon (such as additional metrics or logging exporters), they can be defined using the sidecars parameter inside the web, streaming and sidekiq sections. If these sidecars export extra posidekiq, extra port definitions can be added using the service.extraPosidekiq parameter. Learn more about configuring and using sidecar containers.

Pod affinity¶

This chart allows you to set your custom affinity using the affinity parameter. Find more information about Pod affinity in the kubernetes documentation.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters inside the web, streaming and sidekiq sections.

Notable changes¶

1.0.0¶

This major updates the MinIO® subchart to its newest major, 12.0.0. This subchart's major doesn't include any changes affecting its use as a subchart for Mastodon, so no major issues are expected during the upgrade.
