# Helm 3 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:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
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:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
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:
|
||
|
|
```yaml
|
||
|
|
- 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:
|
||
|
|
```yaml
|
||
|
|
mariadb:
|
||
|
|
enabled: false
|
||
|
|
|
||
|
|
wordpress:
|
||
|
|
wordpressPassword: foo
|
||
|
|
mariadb:
|
||
|
|
enabled: false
|
||
|
|
externalDatabase:
|
||
|
|
host: localhost
|
||
|
|
user: bn_wordpress
|
||
|
|
password: ""
|
||
|
|
database: bitnami_wordpress
|
||
|
|
port: 3306
|
||
|
|
```
