TL;DR;

$ helm install ckotzbauer/postgres-operator

Installing the Chart

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

$ helm install my-release ckotzbauer/postgres-operator

The command deploys the operator on the Kubernetes cluster using the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the my-release installation:

$ helm delete my-release

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

Changes compared to the official chart

• No ConfigMap config-target.
• pod_environment_configmap is created automatically. Contents can be configured via pod_environment_config.
• Enhanced security (dropped ALL capabilities for the operator-pod).
