contrail-configuration not starting up.
- rabbitmq is down
- rabbitmq is trying to connect to a wrong interface (bond2, instead of br-bond2)
- hostname configuration is wrong in the rabbitmqctl status (fixed by editing /etc/rabbitmq/rabbitmq-env.conf)
- ansible manageded configuration in the docker image -> would update /etc/hosts, if the hostname would not be resolvable
- maas managed interfaces, hence they get resolved
- the ansible playbook has wrong assumption where it should cut the host entry from the DNS:
$ /contrail-ansible-internal/playbooks/roles/rabbitmq/tasks/facts.yml: shell: getent hosts {{ rabbitmq_nodes | intersect(ansible_all_ipv4_addresses) | first }} | awk '{print $2}' | cut -d . -f1
$ getent hosts 100.68.100.32 | awk '{print $2}' | cut -d . -f1
bond2
$ getent hosts 100.68.100.32 | awk '{print $2}'
bond2.4-management-1.ic-skbrab1.in.pan-net.eu
--> no such host as bond2 -> rabbitmq fails to startup
could be done similar to the other rabbitmq charms: add the hostname with the binding IP address to the /etc/hosts file to be sure that it goes over the selected interface (and not to depend on the FQDN configuration)
