"docker: 'compose' is not a docker command." How to use the alias "docker compose"?

  • 772

I'm following this guide in order to deploy a docker-compose application in Azure, and the command

docker compose up

is not found in Azure Container Instances (ACI).

I get the following error:

docker: 'compose' is not a docker command. See 'docker --help'

However I switched the context before with:

docker context use "azuremycontext"

Moreover, I cannot execute the command

docker context create aci azuremycontext

Docker doesn't have this option in my Linux. What am I missing here? I guess it is not linked just to ACI, but rather docker-compose itself?

linux docker

    So i found the solution and would like to share it:

    You have to install the docker aci integration in order to use "docker compose" and "docker create context aci [contextname]". You can install it as follows:

    curl -L https://raw.githubusercontent.com/docker/compose-cli/main/scripts/install/install_linux.sh | sh

  3. Taken from 'compose' is not a docker command` when installing using convenience scripts · Issue #8630, this shows the most voted and also most recent answer at the time of writing (08/2022).

    If your docker-compose version does not yet support "docker compose" without a dash in between, you can get the alias "docker compose" for "docker-compose" by installing a plugin.

    If you see:

    docker: 'compose' is not a docker command.
See 'docker --help'

    You need to:

    sudo apt-get install docker-compose-plugin

    Check the plugin for example with:

    $ docker compose version
Docker Compose version v2.6.0
