podman-compose support
Opened this issue · 2 comments

This ticket is to track changes needed in order to have this running under podman and podman-compose instead of docker.
Target is rhel8 / oracle linux 8. No other environments will be tested for now.
Why this? Getting docker to run on Centos 8 / RHEL 8 / OEL 8 is getting difficult and many are dropping docker in favour of podman.
Is this worth doing considering that podman 3.0 (in development) will have built in docker-compose support:

Command reference:
sudo dnf install fuse3 podman git
sudo pip3 install podman-compose
git clone https://github.com/HenryGP/om_ansible.git
cd om_ansible
podman-compose build && podman-compose up -d
podman exec -it provisioner ansible-playbook /root/om_ansible.yaml
To get a container shell:
podman exec -it <container> /bin/bash
Issues that needed to be patched:
- Selinux on the host running podman doesn't work -> no plan to make it work for now
- Exposed ports need to be > 1024 so docker-compose file needs to be amended
- security_opt params don't work, commented them out, not sure if this will cause trouble.
Current main issue, /etc/hosts is not populated correctly:
[vagrant@oracle8 om_ansible]$ podman-compose up -d

sounds like the network model is totally different and it's not easy to make it similar to normal docker-compose...
