Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

---
- name: Converge
  hosts: all
  become: yes
  gather_facts: yes

  roles:
    - role: buluma.haproxy
      haproxy_frontends:
        - name: http
          address: "*"
          port: 80
          default_backend: backend
        - name: https
          address: "*"
          port: 443
          default_backend: backend
          ssl: yes
          crts:
            - /tmp/haproxy.keycrt
        - name: smtp
          address: "*"
          port: 25
          default_backend: smtp
          mode: tcp
      haproxy_backend_default_balance: roundrobin
      haproxy_backends:
        - name: backend
          httpcheck: yes
          balance: roundrobin
          # You can refer to hosts in an Ansible group.
          # The `ansible_default_ipv4` will be used as an address to connect to.
          servers: "{{ groups['all'] }}"
          port: 8080
          options:
            - check
        - name: smtp
          httpcheck: yes
          balance: roundrobin
          # You can also refer to a list of servers.
          servers:
            - name: first
              address: "127.0.0.1"
              port: 25
            - name: second
              address: "127.0.0.2"
              port: 25
          port: 25
          options:
            - check

The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  become: yes
  gather_facts: no

  roles:
    - role: buluma.bootstrap
    - role: buluma.core_dependencies
    - role: buluma.epel
    - role: buluma.buildtools
    - role: buluma.python_pip
    - role: buluma.openssl
      openssl_key_directory: /tmp
      openssl_items:
        - name: haproxy
          common_name: "{{ ansible_fqdn }}"
    # This role is applied to serve as a mock "backend" server. See `molecule/default/verify.yml`.
    - role: buluma.httpd
      httpd_port: 8080
