compose-switch's Introduction

Compose Switch

Compose Switch is a replacement to the Compose V1 docker-compose (python) executable. It translates the command line into Compose V2 docker compose then run the latter.

installation

We provide a script for automated installation:

$ curl -fL https://raw.githubusercontent.com/docker/compose-switch/master/install_on_linux.sh | sh

Manual installation

download compose-switch binary for your architecture

$ curl -fL https://github.com/docker/compose-switch/releases/latest/download/docker-compose-linux-amd64 -o /usr/local/bin/compose-switch

make compose-switch executable

$ chmod +x /usr/local/bin/compose-switch

rename docker-compose binary if you already have it installed as /usr/local/bin/docker-compose

$ mv /usr/local/bin/docker-compose /usr/local/bin/docker-compose-v1

define an "alternatives" group for docker-compose command

$ update-alternatives --install /usr/local/bin/docker-compose docker-compose <PATH_TO_DOCKER_COMPOSE_V1> 1
$ update-alternatives --install /usr/local/bin/docker-compose docker-compose /usr/local/bin/compose-switch 99

check installation

$ update-alternatives --display docker-compose
docker-compose - auto mode
  link best version is /usr/local/bin/compose-switch
  link currently points to /usr/local/bin/compose-switch
  link docker-compose is /usr/local/bin/docker-compose
/usr/bin/docker-compose - priority 1
/usr/local/bin/compose-switch - priority 99

select Compose implementation to run by `docker-compose`

$ update-alternatives --config docker-compose
There are 2 choices for the alternative docker-compose (providing /usr/local/bin/docker-compose).

  Selection    Path                           Priority   Status
------------------------------------------------------------
* 0            /usr/local/bin/compose-switch   99        auto mode
  1            /usr/bin/docker-compose         1         manual mode
  2            /usr/local/bin/compose-switch   99        manual mode
