Quick Start

Connecting via docker-compose

• mounts (read-only) ${SSH_DIR}, defaults to ~/.ssh
• mounts ${WORKSPACE_DIR}, defaults to ./workspace
• mounts various config folders under ./workspace into home:
  • .config
  • .kube
  • .aws

docker-compose up -d
docker-compose exec workspace zsh

Connecting via SSH

# Start the container
docker run -d -e SSH_PASSWORD="supersecret" -p 2233:22 ronalddddd/dev-container

# Shell into it
ssh root@localhost -p 2233

Connecting via Mosh

mosh root@localhost -p 6000 --ssh="ssh -p 1234"

Advanced Usages

• SSH into it using your private key by setting the environment variable DEVELOPER_PUBLIC_KEY
• Mount a project folder to /projects (so you don't lose your work :)
• Mount a .ssh folder with required credentials
  • authorized_keys file for logging in
  • Private keys for accessing remote repositories, etc...
• Expose SSH port
• Expose Mosh port range (UDP 6000 to 6100)

What is Mosh?

Mosh is a replacement for interactive SSH terminals. It's more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.

keeps the session alive if the client goes to sleep and wakes up later, or temporarily loses its Internet connection

• getting a mosh client: https://mosh.org/#getting
• you need to expose one or more UDP ports in the 6000 to 6100 range for mosh clients to connect
