Container-based development environment from any docker image
- Quick setup: current directory is mounted into container, a-la Vagrant
- Solves uid/gid problem: no more
chmodin host OS on files generated in container. For that, a user created in container, which uid and gid are match to owner of current directory.
$ . devcontainer ubuntu:14.04
$ dr cat /etc/release
# Ubuntu 14.04.6 LTS \n \l
Usual workflow:
$ cd myproject
$ . devcontainer ubuntu:14.04
$ dr make # start the build
Interactive session:
$ dr sh # or bash, or ...
If you accidentally lost a terminal with devcontainer setup (suppose container name or hash is mycont):
$ . devcontainer -C mycont
If you like other alias name (alias binds to specific container):
$ . devcontainer -a ra alpine
$ . devcontainer -a ru ubuntu
$ du cat /etc/issue
Ubuntu 18.04.2 LTS \n \l
$ da cat /etc/issue

Docker by default uses CTRL+P as detach prefix. If you want to change the prefix, i.e. to more pleasant work in interactive session with Emacs-like shortcuts:
$ . devcontainer -e "--detach-keys ctrl-_"
