code-server Helm Chart

code-server code-server is VS Code running on a remote server, accessible through the browser.

This chart is community maintained by @Matthew-Beckett and @alexgorbatchev

Quickstart

$ 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 cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.6+

Installing the Chart

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

$ 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 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:

$ 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.

Values

Key	Type	Default
affinity	object	{}
extraArgs	list	[]
extraConfigmapMounts	list	[]
extraContainers	string	""
extraInitContainers	string	""
extraSecretMounts	list	[]
extraVars	list	[]
extraVolumeMounts	list	[]
fullnameOverride	string	""
hostnameOverride	string	""
image.pullPolicy	string	"Always"
image.repository	string	"codercom/code-server"
image.tag	string	"4.6.1"
imagePullSecrets	list	[]
ingress.enabled	bool	false
nameOverride	string	""
nodeSelector	object	{}
persistence.accessMode	string	"ReadWriteOnce"
persistence.annotations	object	{}
persistence.enabled	bool	true
persistence.size	string	"1Gi"
podAnnotations	object	{}
podSecurityContext	object	{}
replicaCount	int	1
resources	object	{}
securityContext.enabled	bool	true
securityContext.fsGroup	int	1000
securityContext.runAsUser	int	1000
service.port	int	8443
service.type	string	"ClusterIP"
serviceAccount.create	bool	true
serviceAccount.name	string	nil
tolerations	list	[]
volumePermissions.enabled	bool	true
volumePermissions.securityContext.runAsUser	int	0

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

$ 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,

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

Tip: You can use the default 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.

Both parameters accept strings and use them as a templates

Example of using extraInitContainers:

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

$ 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.
