# code-server
2+
3+
[code-server](https://github.com/cdr/code-server) code-server is VS Code running
4+
on a remote server, accessible through the browser.
5+
6+
## TL;DR;
7+
8+
```console
9+
$ git clone https://github.com/cdr/code-server.git
10+
$ helm install deployment/chart
11+
```
12+
13+
## Introduction
14+
15+
This chart bootstraps a code-server deployment on a
16+
[Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh)
17+
package manager.
18+
19+
## Prerequisites
20+
21+
- Kubernetes 1.6+
22+
23+
## Installing the Chart
24+
25+
To install the chart with the release name `my-release`:
26+
27+
```console
28+
$ helm install --name my-release deployment/chart
29+
```
30+
31+
The command deploys code-server on the Kubernetes cluster in the default
32+
configuration. The [configuration](#configuration) section lists the parameters
33+
that can be configured during installation.
34+
35+
> **Tip**: List all releases using `helm list`
36+
37+
## Uninstalling the Chart
38+
39+
To uninstall/delete the `my-release` deployment:
40+
41+
```console
42+
$ helm delete my-release
43+
```
44+
45+
The command removes all the Kubernetes components associated with the chart and
46+
deletes the release.
47+
48+
## Configuration
49+
50+
The following table lists the configurable parameters of the nginx-ingress chart
51+
and their default values.
52+
53+

The following table lists the configurable parameters of the code-server chart
55+
and their default values.
56+

| `volumePermissions.enabled` | Enable volume permissions init container | `true` |
81+
| `volumePermissions.securityContext.runAsUser` | User ID for the init container | `0` |
82+
| `securityContext.enabled` | Enable security context | `true` |
83+
| `securityContext.fsGroup` | Group ID for the container | `1000` |
84+

94+
95+
Specify each parameter using the `--set key=value[,key=value]` argument to `helm
96+
install`. For example,
97+
98+
```console
99+
$ helm install --name my-release \
100+
--set persistence.enabled=false \
101+
deployment/chart
102+
```
103+
104+
The above command sets the the persistence storage to false.
105+
106+
Alternatively, a YAML file that specifies the values for the above parameters
107+
can be provided while installing the chart. For example,
108+
109+
```console
110+
$ helm install --name my-release -f values.yaml deployment/chart
111+
```
112+
113+
> **Tip**: You can use the default [values.yaml](values.yaml)
114+
