             Summary: wait_for in check_hosts.yml deployment script should specify port and perhaps regex
                 Key: METRON-85
                 URL: https://issues.apache.org/jira/browse/METRON-85
             Project: Metron
          Issue Type: Bug
            Reporter: David M. Lyle


Currently, the wait_for on line 19 of deployment/amazon-ec2/tasks/check-hosts.yml doesn't specify a port. Ansible simply sleeps for the default timeout in this case (5 minutes).

This wasn't as intended. The deployment should continue as soon as all hosts are able to accept incoming ssh connections.

One thing- there was a corner case revealed in testing where:

- name: Wait for connectivity to host(s)
  wait_for: host={{ item.public_dns_name }} port=22 search_regex=OpenSSH
  with_items: ec2.tagged_instances
  when: item.public_dns_name is defined

actually allowed execution to continue before some of the hosts started accepting external SSH connections, causing the deployment to fail. So, in addition to checking for port 22 to be up, there may additional work required- perhaps making that a local action.
