Salt formula for Virtual Machine High Availability (VMHA) as a service (Masakari)

Some things to consider:

• Fencing will be configured using ipmitool, and assumes the presence of a iDRAC (or similar) for fencing purposes
• Corosync / Pacemaker has a limit of 16 nodes per cluster. Make sure you cluster the nodes appropriately.

Sample pillars

Masakari API / Engine (see also service/server/cluster.yml):

masakari:
  server:
    enabled: true
    version: ${_param:masakari_version}
    debug: false
    api:
      address: ${_param:cluster_local_address}
      port: 15868
    cache:
      engine: memcached

      - host: ${_param:cluster_node01_address}

      - host: ${_param:cluster_node02_address}
        port: 11211
      - host: ${_param:cluster_node03_address}

Masakari monitor (compute node, see metadata/service/monitor/single.yml)

masakari:

      interface: eth0
      bind_address: ${_param:cluster_local_address}
      port: 5405
      rrp_bind_address: ${_param:deploy_address}
    nodes:
      target: G@roles:nova.compute

  monitor:
    enabled: true
    version: ${_param:masakari_version}
    debug: false
    stonith_type: ipmi

    openstack_auth:
      protocol: http
      host: ${_param:cluster_vip_address}

      admin_tenant: service
      admin_domain: default
      admin_region: ${_param:openstack_region}

# Add a mine function that we can re-use when registering hosts in masakari.
mine_functions:
  masakari.clustername:
    - mine_function: pillar.get
    - masakari:corosync:clustername

Installation

Install masakari api and masakari engine on the controller nodes

• Create database

  salt -C 'I@galera:master' state.sls galera

• Add keystone user and endpoint

  salt -C 'I@keystone:client' state.sls keystone.client

• Update salt minion state of monitors

  salt -C 'I@masakari:monitor' state.sls salt.minion

• verify that the salt mine has been updated (should return the clustername for all nodes)

  salt 'cfg01.*' mine.get '*' masakari.clustername

• Install masakari server

  salt -C 'I@masakari:server' state.sls haproxy,masakari -b 1

Compute node installation

• Install masakari monitors (on the compute nodes)

  salt -C 'I@masakari:monitor' state.sls masakari
