make support for mysql dependencies

[torsteinelv]

Just example,

add to chart:
dependencies:

• name: mysql
  version: 9.10.0
  repository: https://charts.bitnami.com/bitnami

add to values:
mysql:
enabled: true
auth:
rootPassword: your-root-password
database: itop
username: itop
password: your-password
primary:
persistence:
enabled: true
size: 10Gi

add to templates/deployment.yaml:
env:

• name: DB_HOST
  value: {{ .Release.Name }}-mysql
• name: DB_USER
  valueFrom:
  secretKeyRef:
  name: {{ .Release.Name }}-mysql
  key: username
• name: DB_PASSWORD
  valueFrom:
  secretKeyRef:
  name: {{ .Release.Name }}-mysql
  key: password
• name: DB_NAME
  value: itop

Good idea, however since Combodo recommends to use MariaDB over MySQL, I would add that as dependency instead. And preferable also the official MariaDB container. PRs are welcome.

Not sure how to create an pr on this.

we can change to chart.yaml
dependencies:

• name: mariadb
  version: ~18.2.4
  repository: https://charts.bitnami.com/bitnami
  condition: mysql.enabled

values:
mysql:
enabled: true
auth:
rootPassword: itop
database: itop
username: itop
password: itop
primary:
persistence:
enabled: true
size: 10Gi
