[code-server](https://github.com/coder/code-server) code-server is VS Code running
on a remote server, accessible through the browser.

This chart is community maintained by [@Matthew-Beckett](https://github.com/Matthew-Beckett) and [@alexgorbatchev](https://github.com/alexgorbatchev)

## Quickstart

```console
$ git clone https://github.com/coder/code-server
$ cd code-server
$ helm upgrade --install code-server ci/helm-chart
```

## Introduction

This chart bootstraps a code-server deployment on a
[Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh)
package manager.

## Prerequisites

- Kubernetes 1.6+

## Installing the Chart

To install the chart with the release name `code-server`:

```console
$ git clone https://github.com/coder/code-server
$ cd code-server
$ helm upgrade --install code-server ci/helm-chart
```

The command deploys code-server on the Kubernetes cluster in the default
configuration. The [configuration](#configuration) section lists the parameters
that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Uninstalling the Chart

To uninstall/delete the `code-server` deployment:

```console
$ helm delete code-server
```

The command removes all the Kubernetes components associated with the chart and
deletes the release.

## Configuration

The following table lists the configurable parameters of the code-server chart
and their default values.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
$ helm upgrade --install code-server \
  ci/helm-chart \
  --set persistence.enabled=false
```

The above command sets the the persistence storage to false.

Alternatively, a YAML file that specifies the values for the above parameters
can be provided while installing the chart. For example,

```console
$ helm upgrade --install code-server ci/helm-chart -f values.yaml
```

> **Tip**: You can use the default [values.yaml](values.yaml)

# Extra Containers

There are two parameters which allow to add more containers to pod.
Use `extraContainers` to add regular containers
and `extraInitContainers` to add init containers. You can read more
about init containers in [k8s documentation](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).

Both parameters accept strings and use them as a templates

Example of using `extraInitContainers`:

```yaml
extraInitContainers: |
  - name: customization
    image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
    imagePullPolicy: IfNotPresent
    env:
      - name: SERVICE_URL
        value: https://open-vsx.org/vscode/gallery
      - name: ITEM_URL
        value: https://open-vsx.org/vscode/item
    command:
      - sh
      - -c
      - |
        code-server --install-extension ms-python.python
        code-server --install-extension golang.Go
    volumeMounts:
      - name: data
        mountPath: /home/coder
```

With this yaml in file `init.yaml`, you can execute

```console
$ helm upgrade --install code-server \
  ci/helm-chart \
  --values init.yaml
```

to deploy code-server with python and golang extensions preinstalled
before main container have started.
