## [Example Playbook](#example-playbook)

This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-keepalived/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.

```yaml

---

- name: Converge

  hosts: all

  become: true

  gather_facts: true

  roles:

    - role: robertdebock.keepalived

      keepalived_vrrp_instances:

        - name: VI_1

          state: MASTER

          interface: eth0

          unicast_src_ip: "172.17.0.6"

          secondary_private_ip: "172.17.0.7"

          virtual_router_id: 51

          priority: 255

          authentication:

            auth_type: PASS

            auth_pass: "12345"

          virtual_ipaddresses:

            - name: "172.17.0.8"

              cidr: 16

```

The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/robertdebock/ansible-role-keepalived/blob/master/molecule/default/prepare.yml):

```yaml

---

- name: Prepare

  hosts: all

  become: true

  gather_facts: false

  roles:

    - role: robertdebock.bootstrap

```

## [Role Variables](#role-variables)

The default values for the variables are set in [`defaults/main.yml`](https://github.com/robertdebock/ansible-role-keepalived/blob/master/defaults/main.yml):

```yaml

---

# defaults file for keepalived

# By default, there is not configuration, because there is no "sane default" to

# set. You'll have to set it yourself. Here are a few hints.

#

# Have a look in `molecule/default/converge.yml` for an example.

# You do not need to set the state to `MASTER`, all nodes can also be set to

# `BACKUP`, in which case a random host will be selected to configure the

# virtual IP. Setting `state` to `MASTER` only initially sets that host to be

# the master. Over time, other nodes will likely become master.

#

# You can see the configure virtual IP using `ip addr list eth0`.

# keepalived_vrrp_instances:

#   # `name` defines an individual instance of the VRRP protocol running on an interface.

#   - name: VI_1

#   # `state` defines the initial state that the instance should start in.

#     state: MASTER

#   # `interface` defines the interface that VRRP runs on.

#     interface: eth0

#   # `unicast_src_ip` contains the primary address for unicasts.

#     unicast_src_ip: "192.168.1.1"

#   # `secondary_private_ip` refers the the peer's unicast address.

#     secondary_private_ip: "192.168.1.2"

#   # `virtual_router_id` is the unique identifier.

#     virtual_router_id: 51

#   # `priority` is the advertised priority.

#     priority: 255

#   # `check_status_command` will make +3 to priority if command return is 0 (optional). example:

#     check_status_command: /sbin/postfix status

#   # `authentication` specifies the information necessary for servers participating in VRRP to authenticate with each other.

#     authentication:

#       auth_type: PASS

#       auth_pass: 12345

#   # `virtual_ipaddress` defines the IP addresses (there can be multiple) that VRRP is responsible for.

#     virtual_ipaddresses:

#       - name: "192.168.122.200"

#         cidr: 24

keepalived_vrrp_instances: []
