DCE

DCE stands for Docker ComposE or Docker Compose Extended. The goal is to simplify the usage of the docker compose commands when using several Compose configuration files or options. The command will read the .dcerc configuration file if present in order to automatically add desired options to the docker compose command.

Installation

Simply copy the dce command of this repository in a folder which is present in your $PATH.

curl -s https://raw.githubusercontent.com/odolbeau/dce/master/dce | sudo tee /usr/local/bin/dce && sudo chmod +x /usr/local/bin/dce

In order to install bash_completion:

curl -s https://raw.githubusercontent.com/odolbeau/dce/master/bash_completion | sudo tee /etc/bash_completion.d/dce

Usage

Automatically add options using a .dcerc file.

In a project which contains several compose configuration files, you can create a .dcerc file like this one:

# Give a name to this project (instead of using the current directory name)
-p my_project name

# includes all needed compose configuration files
-i docker/services/traefik.yml
-i docker/websites/blog.yml
-i docker/websites/another_blog.yml

# Include some secrets stored in a specific env file
--env-file .secrets

Then simply call the dce command and you're done! 👌 Ship this file in your repository to ensure your collaborators use exactly the same config than you!

Dealing with environment files

By default, dce will include .env and .env.prod files if present in the current folder. You can change the default environment used by dce by creating a ~/.config/dce/env file. For example, if this file contains "local", dce will automatically includes env and .env.local files if it exists.

Improvements

Use --project-directory option when provided to look for a .dcerc file in the given folder
