Ansible: Opencast Firewalld Role

This Ansible role provides a simple firewalld configuration for Opencast. The idea behind this set-up is to:

  • Generally allow network communication within the cluster
  • Allow communication via HTTP(S) from the outside world

Requirements

This role uses community.general.dig to look up the IP addresses for the given hostnames. Make sure to have on your host system:

Role Variables

  • opencast_firewall_internal_hosts
    • List of hosts between which to allow all network communication (default: groups["all"])
  • opencast_firewall_http_hosts
    • List of hosts to allow external HTTP communications to (default: groups["all"])
    • Often makes sense to set this to something like groups["opencast"]
  • opencast_firewall_https_hosts
    • List of hosts to allow external HTTPS communications to (default: opencast_firewall_http_hosts)
  • opencast_firewall_ipv4
    • Look up IPv4 addresses of hostnames
  • opencast_firewall_ipv6
    • Look up IPv6 addresses of hostnames

Example Playbook

Example of how to configure and use the role:

- hosts: servers
  become: true
  roles:
    - role: elan.opencast_firewalld
      opencast_firewall_http_hosts: '{{ groups["opencast"] }}'
