This PR adds a few new chart features which adds to the flexibility of the chart.
- allow extra volumes to be mounted (such as secrets): 2f862c5a48
- pass environment variables also to the init-container: 7044049478
- allow a preparation script to be "injected" into the init-container: 6125a69345
As a concrete example of how this can be used, I use is to configure Gitea to use client certificate authentication against an external Postgres database. That could be accomplished by having a `gitea-postgres-ssl` secret:
```
apiVersion: v1
kind: Secret
type: Opaque
metadata:
name: gitea-postgres-ssl
data:
postgresql.crt: <base64...>
postgresql.key: <base64...>
root.crt: <base64...>
```
and then mounting this as a volume in Gitea using:
```
extraVolumes:
- name: postgres-ssl-vol
secret:
secretName: gitea-postgres-ssl
extraVolumeMounts:
- name: postgres-ssl-vol
readOnly: true
mountPath: "/pg-ssl"
```
To get the right permissions on the credentials, we'd use the `initPreScript`:
```
initPreScript: |
# copy postgres client and CA cert from mount and
# give proper permissions
mkdir -p /data/git/.postgresql
cp /pg-ssl/* /data/git/.postgresql/
chown -R git:git /data/git/.postgresql/
chmod 400 /data/git/.postgresql/postgresql.key
```
and to make sure that Gitea uses the certificate we need to pass the proper postgres environment variables (both to the init container and the "main" container):
```
statefulset:
env:
- name: "PGSSLCERT"
value: "/data/git/.postgresql/postgresql.crt"
- name: "PGSSLKEY"
value: "/data/git/.postgresql/postgresql.key"
- name: "PGSSLROOTCERT"
value: "/data/git/.postgresql/root.crt"
```
