# 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: |
|||
|
|||
```yaml |
|||
dependencies: |
|||
- name: wordpress |
|||
version: 5.0.2 |
|||
repository: https://charts.helm.sh/stable |
|||
``` |
|||
|
|||
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://charts.helm.sh/stable |
|||
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 |
|||
``` |
