## Chart Dependencies
|
|
|
|
|
|
|
|
|
|
In Helm, one chart may depend on any number of other charts. These
|
|
|
|
|
dependencies are expressed explicitly by copying the dependency charts
|
|
|
|
|
into the `charts/` directory.
|
|
|
|
|
In Helm, one chart may depend on any number of other charts.
|
|
|
|
|
These dependencies can be dynamically linked through the `requirements.yaml`
|
|
|
|
|
file or brought in to the `charts/` directory and managed manually.
|
|
|
|
|
|
|
|
|
|
A dependency can be either a chart archive (`foo-1.2.3.tgz`) or an
|
|
|
|
|
unpacked chart directory. But its name cannot start with `_` or `.`.
|
|
|
|
|
Such files are ignored by the chart loader.
|
|
|
|
|
Although manually managing your dependencies has a few advantages some teams need,
|
|
|
|
|
the preferred method of declaring dependencies is by using a
|
|
|
|
|
`requirements.yaml` file inside of your chart.
|
|
|
|
|
|
|
|
|
|
**Note:** The `dependencies:` section of the `Chart.yaml` from Helm
|
|
|
|
|
Classic has been completely removed.
|
|
|
|
|
|
|
|
|
|
For example, if the WordPress chart depends on the Apache chart, the
|
|
|
|
|
Apache chart (of the correct version) is supplied in the WordPress
|
|
|
|
|
chart's `charts/` directory:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
wordpress:
|
|
|
|
|
Chart.yaml
|
|
|
|
|
requirements.yaml
|
|
|
|
|
# ...
|
|
|
|
|
charts/
|

|
apache/

# ...

|
mysql/
|
|
|
|
|
Chart.yaml
|
|
|
|
|
# ...
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
The example above shows how the WordPress chart expresses its dependency
|
|
|
|
|
on Apache and MySQL by including those charts inside of its `charts/`
|
|
|
|
|
directory.
|
|
|
|
|
|
|
|
|
|
**TIP:** _To drop a dependency into your `charts/` directory, use the
|
|
|
|
|
`helm fetch` command or use a `requirements.yaml` file_

### Managing Dependencies with `requirements.yaml`
|
|
|
|
|
|
|
|
|
|
While Helm will allow you to manually manage your dependencies, the
|
|
|
|
|
preferred method of declaring dependencies is by using a
|
|
|
|
|
`requirements.yaml` file inside of your chart.
|
|
|
|
|
|
|
|
|
|
A `requirements.yaml` file is a simple file for listing your
|
|
|
|
|
dependencies.

### Managing Dependencies manually via the `charts/` directory
|

If more control over dependencies is desired, these dependencies can
|
|
|
|
|
be expressed explicitly by copying the dependency charts into the
|
|
|
|
|
`charts/` directory.
|
|
|
|
|
|
|
|
|
|
A dependency can be either a chart archive (`foo-1.2.3.tgz`) or an

|
