# nginx: An advanced example chart
|
|
|
|
This Helm chart provides examples of some of Helm's more powerful
|
|
features.
|
|
|
|
**This is not a production-grade chart. It is an example.**
|
|
|
|
The chart installs a simple nginx server according to the following
|
|
pattern:
|
|
|
|
- A `ConfigMap` is used to store the files the server will serve.
|
|
([templates/configmap.yaml](templates/configmap.yaml))
|
|
- A `Deployment` is used to create a Replica Set of nginx pods.
|
|
([templates/deployment.yaml](templates/deployment.yaml))
|
|
- A `Service` is used to create a gateway to the pods running in the
|
|
replica set ([templates/service.yaml](templates/service.yaml))
|
|
|
|
The [values.yaml](values.yaml) exposes a few of the configuration options in the
|
|
charts, though there are some that are not exposed there (like
|
|
`.image`).
|
|
|
|
The [templates/_helpers.tpl](templates/_helpers.tpl) file contains helper templates. The leading
|
|
underscore (`_`) on the filename is semantic. It tells the template renderer
|
|
that this file does not contain a manifest. That file declares some
|
|
templates that are used elsewhere in the chart.
|
|
|
|
Helpers (usually called "partials" in template languages) are an
|
|
advanced way for developers to structure their templates for optimal
|
|
reuse.
|
|
|
|
You can deploy this chart with `helm install docs/examples/nginx`. Or
|
|
you can see how this chart would render with `helm install --dry-run
|
|
--debug docs/examples/nginx`.
