Devpod

Preliminary

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

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 -> clusters.cluster.server-data
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 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

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: xxxxxxxxxxxx
    client-key: xxxxxxxxxxxxxxxx

Create workspace

  1. get git repo link
  2. choose appropriate provider
  3. choose ide type and version
  4. and go!

Useful Command

download kubectl binary

MIRROR="files.m.daocloud.io/"
VERSION=$(curl -L -s https://${MIRROR}dl.k8s.io/release/stable.txt)
[ $(uname -m) = x86_64 ] && curl -sSLo kubectl "https://${MIRROR}dl.k8s.io/release/${VERSION}/bin/linux/amd64/kubectl"
[ $(uname -m) = aarch64 ] && curl -sSLo kubectl "https://${MIRROR}dl.k8s.io/release/${VERSION}/bin/linux/arm64/kubectl"
chmod u+x kubectl
mkdir -p ${HOME}/bin
mv -f kubectl ${HOME}/bin
​

Everything works fine.

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

download argocd binary

MIRROR="files.m.daocloud.io/"
VERSION=v2.9.3
[ $(uname -m) = x86_64 ] && curl -sSLo argocd "https://${MIRROR}github.com/argoproj/argo-cd/releases/download/${VERSION}/argocd-linux-amd64"
[ $(uname -m) = aarch64 ] && curl -sSLo argocd "https://${MIRROR}github.com/argoproj/argo-cd/releases/download/${VERSION}/argocd-linux-arm64"
chmod u+x argocd
mkdir -p ${HOME}/bin
mv -f argocd ${HOME}/bin

exec into devpod

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