Fails at TASK [Install Docker Compose using Pip.]

[Chris Paterson]

I'm on a Raspberry PI 4, "Raspbian GNU/Linux 12 (bookworm)".

Error is:
The license_file parameter is deprecated, use license_files instead
Googling, this seems to be because docker-compose has as requirement on pyyaml of <6,>=3.10 and it needs 6.0.1 or 3.5.1 to install successfully.

The basic problem seems to be the ansible task is installing docker-compose version 1 which has been deprecated.

I used
sudo apt install docker-compose
to install V2 manually and the ansible playbook then proceeded past the install docker-compose step OK.

What do people think - is my analysis correct? I am not certain.

This fix worked for me... Thanks!

This seems to be the full error:

manumaiden@manumaidenpi:~ $ pip install docker-compose
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

Which is coming from the docker.yml task :

$ cat tasks/docker.yml | egrep Pip -A4
- name: Install Docker Compose using Pip.
  ansible.builtin.pip:
    name: docker-compose
    state: present
    executable: pip3

The solution could be to add docker-compose to the list of the dependencies:

$ cat tasks/docker.yml | egrep '\(Debian' -A10
- name: Ensure dependencies are installed (Debian).
  ansible.builtin.apt:
    name:
      - libffi-dev
      - libssl-dev
      - python3-dev
      - python3-pip
      - git
      - rsync
      - docker-compose
    state: present
  when: ansible_facts.os_family == "Debian"

But this will create a problem with the previous version of Debian (actually I am not sure if the docker-compose can be installed via apt also on the previous version). So probably a condition to verify which distro is running on the target host could be considered:

$ ansible -m setup 192.168.88.3 | egrep distribution_version
        "ansible_distribution_version": "12.2"

Sorry, I'm a bit lost.

I used sudo apt install docker-compose to install V2 manually and the ansible playbook then proceeded past the install docker-compose step OK.

How did you make this get you docker-compose v2? The deprecation statement is written a little weird and seems to only provide hints in the context of docker desktop or "Moby".

I added the docker apt repo, but that doesn't show a package for docker-compose newer than what raspbian (debian 12) ships with already.

pi@raspberrypi:~/internet-pi $ sudo apt-cache policy | grep dock
 500 https://download.docker.com/linux/debian bookworm/stable arm64 Packages
     origin download.docker.com

pi@raspberrypi:~/internet-pi $ apt search docker-compose
docker-compose/stable,stable 1.29.2-3 all
  define and run multi-container Docker applications with YAML
...

Adding docker-compose to tasks/docker.yml doesn't seem to prevent ansible from trying to install the python library.

Note that Compose V2 is a Go project, so it won’t be available as a Python library. Only Compose V1 is available via pip.

Which seems to say that there is no more python library starting with v2.

I have exact the same Problem.. Manually Install docker-compose also not works... same error:

sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGED

Then it works ;)
