gchiesa.swarm

Install and setup a swarm cluster on Enterprise Linux

Role Variables

# proxy server to use for yum installation
proxy: ""

# consul hostname to use for registering
# it will be randomly choosen from the consul_cluster host group
consul_random_hostname: "{{ groups['consul_cluster'] | random | string }}"

# iptables configuration file
iptables_config: "/etc/sysconfig/iptables"

# set true if the host is natted
host_natted: false

The cluster is built based on the existence of hosts in two specific hostgroups:

swarm_managers : should contain the manager nodes swarm_agents : should contain all the node that should be part of the swarm cluster

Dependencies

This role depends on gchiesa.consul since it uses consul as discovery service

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: all
  roles:
     - { role: gchiesa.swarm }

The inventory should mention the groups for consul_cluster and swarm_nodes and managers. Check the example inventory below:

[targets:vars]
ansible_host=localhost
ansible_become=true
ansible_ssh_user=vagrant
ansible_ssh_private_key_file=~/.vagrant.d/insecure_private_key
proxy=

[consul_cluster:vars]
consul_bootstrap_hostname=test01.local

[targets]
test01.local ansible_port=2200
test02.local ansible_port=2201
test03.local ansible_port=2202
test04.local ansible_port=2203  

[consul_cluster]
test01.local
test02.local
test03.local

[swarm_agents]
test01.local
test02.local
test03.local
test04.local

[swarm_managers]
test01.local
test02.local
