Catena Ansible Role: podman-traefik

Manage Traefik HTTP reverse proxy and load balancer via Ansible using File provider with custom YAML configuration files. The File provider is useful in combination with Podman because Traefik Docker provider is not yet supported (See #5730).

To manage Rootless containers with Podman and systemd services, check the ansible-podman-systemd role.

Role variables

podman_containers

List of Podman containers to manage with Traefik when frontend is set to yes.

# Defaults
podman_containers: []

# Example
podman_containers:
  - name: whoami   # Podman container name
    state: created # (created|absent), default is `created`
    frontend: yes  # (yes|no), default is `no`

This role requires a file named {{ item.name }}.yml into the directory {{ playbook_dir }}/traefik which contains Traefik settings relative to the container in YAML format. Here's an example:

# `service_ip` is a helper equals to `traefik_server_ip` (see below)
http:
  routers:
    whoami:
      rule: "Host(`whoami.example.com`)"
      service: whoami
      tls: true

  services:
    whoami:
      loadBalancer:
        servers:
          - url: "http://{{ service_ip }}:8081"
