%%DESCRIPTION%% (check existing examples)

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/%%CHART_NAME%%

%%INTRODUCTION%% (check existing examples)

• Kubernetes 1.19+
• Helm 3.2.0+
• PV provisioner support in the underlying infrastructure
• ReadWriteMany volumes for deployment scaling

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

helm install my-release bitnami/%%CHART_NAME%%

The command deploys %%CHART_NAME%% 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

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.

See https://github.com/bitnami-labs/readme-generator-for-helm to create the table

The above parameters map to the env variables defined in bitnami/%%CHART_NAME%%. For more information please refer to the bitnami/%%CHART_NAME%% image documentation.

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

helm install my-release \
  --set %%CHART_NAME%%Username=admin \
  --set %%CHART_NAME%%Password=password \
  --set mariadb.auth.rootPassword=secretpassword \
    bitnami/%%CHART_NAME%%

The above command sets the %%CHART_NAME%% administrator account username and password to admin and password respectively. Additionally, it sets the MariaDB root user password to secretpassword.

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/%%CHART_NAME%%

Tip: You can use the default values.yaml

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.

%%IF NEEDED%%

You may want to have %%CHART_NAME%% 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 MariaDB installation with the mariadb.enabled option. Here is an example:

mariadb.enabled=false
externalDatabase.host=myexternalhost
externalDatabase.user=myuser
externalDatabase.password=mypassword
externalDatabase.database=mydatabase
externalDatabase.port=3306

%%IF NEEDED%%

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 ingress.enabled to true. 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. 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.

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.

The Bitnami %%CHART_NAME%% image stores the %%CHART_NAME%% data and configurations at the /bitnami path of the container. Persistent Volume Claims are used to keep the data across deployments. Learn more about persistence in the chart documentation.

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

%%CHART_NAME%%:
  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.

If additional containers are needed in the same pod as %%CHART_NAME%% (such as additional metrics or logging exporters), they can be defined using the sidecars parameter. If these sidecars export extra ports, extra port definitions can be added using the service.extraPorts parameter. Learn more about configuring and using sidecar containers.

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.
