Devpod

Preliminary

Kubernetes has installed, if not check 🔗link
Devpod has installed, if not check 🔗link

1. Get provider config

# just copy ~/.kube/config

for example, the original config

apiVersion: v1
clusters:
- cluster:
    certificate-authority: <$file_path>
    extensions:
    - extension:
        provider: minikube.sigs.k8s.io
        version: v1.33.0
      name: cluster_info
    server: https://<$minikube_ip>:8443
  name: minikube
contexts:
- context:
    cluster: minikube
    extensions:
    - extension:
        provider: minikube.sigs.k8s.io
        version: v1.33.0
      name: context_info
    namespace: default
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    client-certificate: <$file_path>
    client-key: <$file_path>

you need to rename clusters.cluster.certificate-authority, clusters.cluster.server, users.user.client-certificate, users.user.client-key.

clusters.cluster.certificate-authority -> clusters.cluster.certificate-authority-data
clusters.cluster.server -> ip set to `localhost`
users.user.client-certificate -> users.user.client-certificate-data
users.user.client-key -> users.user.client-key-data

the data you paste after each key should be base64

cat <$file_path> | base64

then, modified config file should be look like this:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: xxxxxxxxxxxxxx
    extensions:
    - extension:
        provider: minikube.sigs.k8s.io
        version: v1.33.0
      name: cluster_info
    server: https://127.0.0.1:8443 
  name: minikube
contexts:
- context:
    cluster: minikube
    extensions:
    - extension:
        provider: minikube.sigs.k8s.io
        version: v1.33.0
      name: context_info
    namespace: default
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    client-certificate-data: xxxxxxxxxxxx
    client-key-data: xxxxxxxxxxxxxxxx

then we should forward minikube port in your own pc

#where you host minikube
MACHINE_IP_ADDRESS=10.200.60.102
USER=ayay
MINIKUBE_IP_ADDRESS=$(ssh -o 'UserKnownHostsFile /dev/null' $USER@$MACHINE_IP_ADDRESS '$HOME/bin/minikube ip')
ssh -o 'UserKnownHostsFile /dev/null' $USER@$MACHINE_IP_ADDRESS -L "*:8443:$MINIKUBE_IP_ADDRESS:8443" -N -f

2. Create workspace

get git repo link
choose appropriate provider
choose ide type and version
and go!

Useful Command

Install Kubectl

for more information, you can check 🔗link to install kubectl

How to use it in devpod

Everything works fine.
when you in pod, and using kubectl you should change clusters.cluster.server in ~/.kube/config to https://<$minikube_ip>:8443
exec into devpod

kubectl -n devpod exec -it <$resource_id> -c devpod -- bin/bash

add DNS item

10.aaa.bbb.ccc gitee.zhejianglab.com

shutdown ssh tunnel

# check if port 8443 is already open
netstat -aon|findstr "8443"

# find PID
ps | grep ssh

# kill the process
taskkill /PID <$PID> /T /F

# check if port 8443 is already open
netstat -aon|findstr "8443"

# find PID
ps | grep ssh

# kill the process
kill -9 <$PID>

JumpServer

          Local             Jumpserver        virtual node (develop/k3s)
        ________            _______                ________ 
       ╱        ╲          ╱       ╲╲             ╱        ╲
      ╱         ╱ ------  ╱        ╱╱  --------  ╱         ╱
     ╱         ╱         ╱         ╱            ╱         ╱ 
     ╲________╱          ╲________╱             ╲________╱  
    IP: 10.A.B.C    IP: jumpserver.ay.dev   IP: 192.168.100.xxx

Modify SSH Config

30022 has ssh service at jumpserver

cat .ssh/config
Host jumpserver
  HostName jumpserver.ay.dev
  Port 30022
  User ay
  IdentityFile ~/.ssh/id_rsa

Host virtual
  HostName 192.168.100.xxx
  Port 22
  User ay
  ProxyJump jumpserver
  IdentityFile ~/.ssh/id_rsa

And then you can directly connect to the virtual node

Forward port in virtual node

30022 has ssh service at jumpserver
32524 is a service which you wanna forward

ssh -o 'UserKnownHostsFile /dev/null' -o 'ServerAliveInterval=60' -L 32524:192.168.100.xxx:32524 -p 30022 ay@jumpserver.ay.dev
