DCE

Simple command for running shell commands in a docker container started by docker compose.

Install

Run gem install dce. If you only want to install it for your own user, use the --user-install flag.

Usage

Usage: dce [OPTIONS]... COMMAND
Runs COMMAND in docker compose container.

On first run, asks for the service container to use and saves it to .dce_container next
to the docker-compose.yml file.

If no command given, opens a shell.

Options:
-c, --container SERVICE     use the container of the specified service
replaces the selected container in the .dce_container
-v, --verbose               print exec'ed command
-n, --dry-run               only print exec'ed command, don't run
-?, --print-service         print the service saved
-l, --list-containers       print the containers available
-h, --help                  print this help and exit

Optional, but nice, setup

• Add .dce_container to $HOME/.config/git/ignore.
• alias dc="docker compose"
• alias dcd="dce drush"

Limitations

DCE currently require the container to have /bin/sh.

Development

To run tests, you'll need docker compose (obviously), and cucumber:

gem install --user-install cucumber

Use make test to run the test-suite.
