 # Octopod

-### This is beta version of a chart!
-
 [Octopod](https://octopod.site/) is a fully open-source self-hosted solution for managing multiple deployments in a Kubernetes cluster with a user-friendly web interface. Managing deployments does not require any technical expertise.

 ## TL;DR
 ```console
-helm repo add typeable https://typeable.github.io/octopod/
-kubectl create ns octopod-deployment
-helm install octopod typeable/octopod --set octopod.baseDomain="your-domain.com"
+$ helm repo add typeable https://typeable.github.io/octopod/
+$ kubectl create ns octopod-deployment
+$ helm install octopod typeable/octopod --set octopod.baseDomain="your-domain.com"

 ```console
 $ helm repo add typeable https://typeable.github.io/octopod/
-# helm -n octopod install my-release typeable/octopod 
+$ helm -n octopod install my-release typeable/octopod --set octopod.baseDomain="your-domain.com"

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

 The command removes all the Kubernetes components but PVC's associated with the postgres chart and deletes the release.

+## Note about generated values
+Some values (such as passwords) in this chart (and its dependencies) are generated automatically, but due to [a limitation in helm](https://github.com/helm/charts/issues/5167) the values are changing on every upgrade. To prevent this you must fix these values by providing them via `--set` flags or in the [values file](https://helm.sh/docs/chart_template_guide/values_files/).
+
+These values are:
+- `postgresql.postgresqlPassword` - main db password
+- `postgresql.postgresqlPostgresPassword` - password for "postgres" user
+- `octopod.cliAuthSecret` - auth header for octo cli tool
+- `octopod.uiAuthSecret` - basic auth secret for ui->octopod communication
+
+Note: if these values are not provided, the `helm upgrade` command can fail or Octopod will not work after the upgrade.
