@ -120,76 +120,7 @@ When upgrading, make sure you have the following enabled:
- Persistency for both mariadb + Gitea
- Using `existingGiteaClaim`
- Due to using the [bitnami/mariadb](https://github.com/helm/charts/tree/master/stable/mariadb) chart, make sure to HARDCODE your passwords within `values.yaml`,
or (better) set them in a separate secret named in mariadb.existingSecret. Or else you'll be unable to update mariadb
## Secrets
Secret values (database passwords, Gitea internal secrets / tokens) are passed to the containers using Kubernetes secrets.
These secrets can be automatically created using parameters from values.yaml or created externally and specified by name.
### MariaDB
If using the default MariaDB database, create the secret per the bitnami mariadb chart and specify its name in `mariadb.existingSecret`.
The secret will be created automatically if unspecified or if the password is supplied via `values.yaml`.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: RELEASE-NAME-mariadb
type: Opaque
data:
mariadb-root-password: "<base64-encoded password>"
mariadb-password: "<base64-encoded password>"
```
### ExternalDB
If using a different database, specify the secret name in `externalDB.secretName`.
If this secret is shared with the database itself and has the password in a key other than `db-password`, you can specify the key name via `externalDB.passwordKey`.
The secret will be created automatically if the password is supplied via `values.yaml`.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: RELEASE-NAME-externaldb
type: Opaque
data:
db-password: "<base64-encoded password>"
```
### Gitea Secrets
Gitea requires a number of internal secret tokens, which can be supplied via an externally-created secret or via `values.yaml`.
If they are not supplied, they will be auto-generated by the init container, and will change on upgrades.
Gitea requires particular encoding for some of these so they should be generated using `gitea generate secret`.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: RELEASE-NAME
type: Opaque
data:
secret-key: "base64-encoded secret"
jwt-secret: "base64-encoded secret"
lfs-jwt-secret: "base64-encoded secret"
internal-token: "base64-encoded secret"
```
## Immutable Configuration
If `config.immutableConfig` is `true`, the Gitea `app.ini` is regenerated each time the init container runs and is set as read-only.
If it is `false`, then `app.ini` is generated only on first install and is editable by Gitea.
- Due to using the [bitnami/mariadb](https://github.com/helm/charts/tree/master/stable/mariadb) chart, make sure to HARDCODE your passwords within `values.yaml`. Or else you'll be unable to update mariadb
