Docker Remote Development Environment

This Docker image is a full Debian Linux environment running GoTTY, which allows you to access a TTY inside the container from your web browser.

Usage

docker run -p 8080:8080 richardcarls/remotedev

A GoTTY instance is available on port 8080 running /bin/login by default. Check the container log for the generated root password to login, or supply one with -e ROOT_PASSWORD.

Run as user

docker run -e LOGIN_UID=`id myuser -u` -p 8080:8080 richardcarls/remotedev

By specifying LOGIN_UID, the init script creates a user in the container for login. The sudo command is available inside the container and the user is automatically added to the sudo group. The default user name dev can be overriden with -e LOGIN_NAME. Check the log for the generated login password, or specify one with -e LOGIN_PASSWORD.

Mounting home directory

docker run -v /some/host/directory:/userdata -p 8080:8080 richardcarls/remotedev

/userdata is symlinked to the container user's $HOME (or /root if running as root). If LOGIN_UID is not specified, the uid of the mounted host directory is used to create the login user. The init script does not modify permissions on this folder so it should be safe to mount your local home directory.

Configure GoTTY

By default, gotty runs /bin/login and reads default options from a provided .gotty configuration file in /userdata. The default config allows browser client write (--permit-write) and reconnect (--reconnect, --reconnect-timeout=10). You may override these and supply other gotty options via docker command, environment variables, or a custom .gotty config in your mounted /userdata directory.

Included packages

The below packages are included on top of the base debian image:

• acl
• bash-completion
• curl
• git
• gpg
• pwgen
• nano
• sudo
• tmux
• wget

Install additional packages on container start

You can specify additional packages to install at container start by setting -e INSTALL_PACKAGES.

docker run -v /some/host/directory:/userdata -e INSTALL_PACKAGES="emacs-nox nodejs" -p 8080:8080 richardcarls/remotedev

Run a startup script on ontainer start

Provide the path to a startup script to run with -e STARTUP_EXEC (relative to $HOME).

docker run -v /some/host/directory:/userdata -e STARTUP_EXEC="your-startup-script.sh" -p 8080:8080 richardcarls/remotedev
