Rabbitmq HA settings

[gil0109]

Thank you for the fix with the hostname. That is all working.

What I noticed is that the default queue "/" is not set to HA-All. So this means that the queues aren't replicating between pods. So during patching, i am not getting true HA.

I am not sure if you want to add this but I added another entry to the config.map called policy.json with the following contents:

Note: I changed the user name and password in my config :)

{
  "vhosts":[
    {
      "name": "/"
    }
  ],
  "users": [
      {
        "name": "guest",
        "password": "guest",
        "hashing_algorithm": "rabbit_password_hashing_sha256",
        "tags": "administrator"
      }
  ],
  "permissions": [
    {
      "user": "guest",
      "vhost": "\/",
      "configure": ".*",
      "write": ".*",
      "read": ".*"
    }
  ],
  "policies":[
    {
      "vhost": "/",
      "name": "ha-all",
      "pattern": "", 
      "definition": {
        "ha-mode": "all",
        "ha-sync-mode": "automatic",
        "ha-sync-batch-size": 5
      }
    }
  ]
}

Then added this line to the bottom of the rabbitmq.conf config.map entry:

management.load_definitions = /etc/rabbitmq/policy.json

And updated the deployment.yaml with:

      volumes:
        - configMap:
            defaultMode: 420
            items:
              - key: rabbitmq.conf
                path: rabbitmq.conf
              - key: enabled_plugins
                path: enabled_plugins
              **- key: policy.json
                path: policy.json**
            name: rabbitmq-config
          name: config-volume

I also put updated the resource settings :

CPU: 300 millicores to 1 core
Memory: 1 GiB to 2 GiB

PS. I haven't tried the new Quorum features yet.
