Code Server

Code Server is an open-source project that allows you to run Visual Studio Code (VS Code) in a web browser.

Installation

Create the following directory structure for Code Server:

 code-server/
 ├── ingress.yml
 ├── pvc.yml
 ├── secret.yml
 ├── svc.yml
 └── code-server.yml

Add the following content to code-server/ingress.yml:

---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: code-server-ingress
  namespace: tools
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-cloudflare
    traefik.ingress.kubernetes.io/router.middlewares: tools-authelia@kubernetescrd
    traefik.ingress.kubernetes.io/router.entrypoints: websecure
spec:
  ingressClassName: traefik
  tls:
  - hosts:
    - vs.akshun-lab.cc
    secretName: code-server-tls
  rules:
  - host: vs.akshun-lab.cc
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:

Add the following content to code-server/pvc.yml:

---
