Ansible Role Podman Systemd

Configure podman pod and container systemd untis

Role Variables

podman_systemd_service_path: /etc/systemd/system
podman_systemd_container_service_prefix: "container"
podman_systemd_pod_service_prefix: "pod"

The location where systemd service files should be instead. You can also configure the prefix of the service name.

podman_systemd_default_wants: network.target
podman_systemd_default_after: network-online.target
podman_systemd_default_restart: on-failure
podman_systemd_default_wantedby: multi-user.target default.target

The default values for systemd services. You can also change those values for each pod / container (see below).

podman_systemd_default_container_detached: false

Containers start attached by default so you can catch the output in the syslog. If you want do detach them, change to true. This can be changed for each pod / container (see below).

All other variables can be found in defaults/main.yml

Caveats

While this role theoretically supports to run a rootless container or pod with a "non main user group" (e.g. user "test" and group "asdf" instead of group "test") there might be some caveats with subuids/gids in such a constellation.

Example container variable

podman_containers:
  - name: nginx
    run_as_user: root
    run_args:
      -p 80:80
    image: nginx:latest
  - name: node-exporter
    run_as_user: prometheus
    run_args:
      -p 9100:9100
    image: quay.io/prometheus/node-exporter:v1.0.1

Example pod variable

podman_pods:
  - name: nextcloud
    run_as_user: nextcloud
    run_user_subid: 500000:100000
    run_args:
      -p 8080:80
    restart: always
    containers:
      - name: db
        image: mariadb
        detached: true
        run_args:
          -v nextcloud-db:/var/lib/mysql
          -e MYSQL_ROOT_PASSWORD=rootpw
          -e MYSQL_PASSWORD=123
          -e MYSQL_DATABASE=nextcloud
          -e MYSQL_USER=nextcloud
        cmd_args:
          --transaction-isolation=READ-COMMITTED
          --binlog-format=ROW
      - name: app
        image: nextcloud
        run_args:
          -v nextcloud-app:/var/www/html
          -e MYSQL_ROOT_PASSWORD=rootpw
          -e MYSQL_PASSWORD=123
          -e MYSQL_DATABASE=nextcloud
          -e MYSQL_USER=nextcloud
