[hhouissa]

the playbook fails with below error:
Unable to load docker-compose. Try pip install docker-compose. Error: Traceback (most recent call last):\n File \"/tmp/ansible_docker_service_payload_MtsKkc/ansible_docker_service_payload.zip/ansible/modules/cloud/docker/_docker_service.py

server is new redhat7 and has only what comes from redhat.
all playbooks ran fine except the awx role.
would you please advise?
Thanks,

Information from destination server:
[ansible@rhel7-prod ~]$ docker-compose --version
docker-compose version 1.24.1, build 4667896b
[ansible@rhel7-prod ~]$ sudo su
[root@rhel7-prod ansible]# docker-compose --version
bash: docker-compose: command not found
[root@rhel7-prod ansible]# npm --version
3.10.10
[root@rhel7-prod ansible]# docker --version
Docker version 19.03.5, build 633a0ea
[root@rhel7-prod ansible]# docker-compose --version
bash: docker-compose: command not found
[root@rhel7-prod ansible]# pip --version
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

How come docker-compose gets installed for the ansible user (same user as in ansible server) but not for the root?

I think I have same issue on my Centos 7(1901) server.

Problem is that python module docker-compose is not installed. I tried to fix that manualy and failed on missing dev python libraries. I fixed that by installing them by yum install python-devel

Then i came into another issue, that python module docker-py is installed, which is in confilct with docker-compose. It is referenced in install manual https://github.com/ansible/awx/blob/devel/INSTALL.md#prerequisites-3

I believe there is an issue in the dependency tree somewhere when bringing down docker-compose.

having the following tasks post the suggested awx - per-requisite install seems to fix issues (note how it is forcing the correct version of more-itertools for python 2.7.*)

` tasks:

• name: uninstall docker-py
  pip:
  name: docker-py
  state: absent
• name: 'Docker reqs'
  yum:
  name: python-devel
  state: present
• name: gcc
  yum:
  name: gcc
  state: present
• name: 'Install docker-compose library'
  pip:
  name: docker-compose
• name: Force correct version of more-itertools
  pip:
  name: more-itertools
  version: 5.0.0
  state: forcereinstall

Hi Guys,

I believe I have run into the same issue and have found a work around. Although I have not tested AWX functionality any further than the initial install and login..

I ran a pre_task to install python3
Update geerlinguy-pip vars:

  pip_package: python3-pip
  pip_executable: pip3
  pip_install_pacakges:
    - name: docker
    - name: docker-compose
    - name: selinux

I added "-e ansible_python_interpreter=/usr/bin/python3" to the "Run the AWX Installation playbook" task in aws-install-playbook.yml (geerlingguy.awx):

ansible-playbook -i inventory install.yml -e postgres_data_dir={{ postgres_data_dir }} -e ansible_python_interpreter=/usr/bin/python3

I have to restart Docker after it completes (not sure why) but after doing so it finishes the migration and I am able to login to the GUI.

This issue is no longer marked for closure.

@thursdaddy suggestion worked for me. The awx installer assumes python3, so if that's not your default...
