Helm Dependencies
This example application demonstrates how an OTS (off-the-shelf) helm chart can be retrieved and pinned to a specific helm sem version from an upstream helm repository, and customized using a custom values.yaml in the private git repository.
In this example, the wordpress application is pulled from the stable helm repo, and pinned to v5.0.2:
dependencies:
- name: wordpress
version: 5.0.2
repository: https://kubernetes-charts.storage.googleapis.com
A custom values.yaml is used to customize the parameters of the wordpress helm chart:
wordpress:
wordpressPassword: foo
mariadb:
db:
password: bar
rootUser:
password: baz
Subchart Note
The wordpress chart referenced in this example contains a subchart for mariadb as specified in the requirements.yaml file of the wordpress chart:
- name: mariadb
version: 5.x.x
repository: https://kubernetes-charts.storage.googleapis.com/
condition: mariadb.enabled
tags:
- wordpress-database
In order to disable this chart, you must set the value to false for both mariadb.enabled and wordpress.mariadb.enabled. The first is used by the mariadb subchart condition field, the second is used by the wordpress chart deployment template. An example demonstration is available in the values-nomaria.yaml file:
mariadb:
enabled: false
wordpress:
wordpressPassword: foo
mariadb:
enabled: false
externalDatabase:
host: localhost
user: bn_wordpress
password: ""
database: bitnami_wordpress
port: 3306
