It is an example.** 7 8 The chart installs a simple nginx server according to the following 9 pattern: 10 11 - A `ConfigMap` is used to store the files the server will serve. 12 ([templates/configmap.yaml](templates/configmap.yaml)) 13 - A `Deployment` is used to create a Replica Set of nginx pods. 14 ([templates/deployment.yaml](templates/deployment.yaml)) 15 - A `Service` is used to create a gateway to the pods running in the 16 replica set ([templates/service.yaml](templates/service.yaml)) 17 18 The [values.yaml](values.yaml) exposes a few of the configuration options in the 19 charts, though there are some that are not exposed there (like 20 `.image`). 21 22 The [templates/_helpers.tpl](templates/_helpers.tpl) file contains helper templates. The leading 23 underscore (`_`) on the filename is semantic. It tells the template renderer 24 that this file does not contain a manifest. That file declares some 25 templates that are used elsewhere in the chart. 26 27 Helpers (usually called "partials" in template languages) are an 28 advanced way for developers to structure their templates for optimal 29 reuse. 30 31 You can deploy this chart with `helm install docs/examples/nginx`. Or 32 you can see how this chart would render with `helm install --dry-run 33 --debug docs/examples/nginx`.
