Kubox

On-demand dev box on kubernetes cluster

Dev boxes should be containerized and cloud native too.

Supports 3 modes of connection

• kubectl exec (tunnel through http works anywhere)
• ssh (port 50022, better performance, needs ssh connection)
• mosh (port 50023, best performance, needs UDP connection)

Features

• Remote development anywhere
• Using existing docker on the Kubernetes host
• Home directory on Persistent volume
• Dev Environment setup using zzh8829/dotfiles
• No more one-off ad-hoc droplet/ec2/vps
• ssh port tcp:50022, mosh port udp:50023

Usage

kubectl apply -f .
./shell # kubectl exec
# copy ssh key
kubectl cp ~/.ssh/id_rsa.pub $KUBOX_POD:/home/kubox/.ssh/authorized_keys
./shell mosh # mosh
./shell ssh # ssh

Downside

• Docker run works but mounting directory is difficult
• Docker build depends on host docker version

Other steps

# copy ssh key
# gen ssh key
ssh-keygen -N "" -C kubox
