Simplify the usage of containers

Project description


Simplify the usage of containers.

You may be thinking, why do I need a new library that wrap-up docker-compose or podman-compose if they are already really simple to use?

Yes, they are simple to use, but if you have some other parameters to the compose command line, it could be very tedious to write them every time such as --env-file, --project-name, --file, etc.

So, in this case we could use something like a script or make, right?

Yes, and just for one project it would be good enough. But, if you maintain or collaborate a bunch of projects, it would be like a boiler plate.

Additionally, if you are maintaining some extra scripts in order to improve your containers stack, these scripts would be like a boilerplate as well.

So, the idea of this project is to organize your stack of containers, gathering some useful scripts and keeping this information centralized in a configuration file. So the command line would be very simple.

How to Install

$ pip install containers-sugar


The commands from docker-compose available are:

  • build
  • config
  • create
  • down
  • events
  • exec
  • images
  • kill
  • logs
  • pause
  • port
  • ps
  • pull
  • push
  • restart
  • rm
  • run
  • start
  • stop
  • top
  • unpause
  • up
  • version

These commands are available in the main profile/plugin, so you don't need to specify any extra parameter to access them.

For extra commands, we are gathering them into a profile/plugin called ext, so you can access them using something like: sugar ext restart.

The current available ext commands are:

  • start -> alias for up
  • restart -> runs stop and up

How to use it

First you need to place the config file .sugar.yaml in the root of your project. This is an example of a configuration file:

version: 1.0
compose-app: docker compose
  group: {{ env.ENV }}
    project-name: project1
      - containers/tests/group1/compose.yaml
    env-file: .env
      default: service1,service3
        - name: service1
        - name: service2
        - name: service3
    project-name: null
    compose-path: containers/tests/group2/compose.yaml
    env-file: .env
        - name: service1
        - name: service3

Some examples of how to use it:

  • build the defaults services (service1,service3) for group1: sugar build --group group1

  • build the all services (there is no default service defined) for group2: sugar build --group group2

  • build all services (ignore default) for group1: sugar build --group group1 --all

  • start the default services for group1: sugar ext start --group group1

  • restart all services (ignore defaults) for group1: sugar ext restart --group group1 --all

  • restart service1 and service2 for group1: sugar ext restart --group group1 --services service1,service2

NOTE: If you use: default: group: {{ env.ENV }}, you don't need to give --group <GROUP_NAME>, except if you want a different group than the default one.
