xtoph-deploy.yml

##
##    Using Ansbile tags are horrible when coupled with
##    import_playbooks.  Thus, we use a variable called
##    'xtoph_deploy_cmd' to determine what to execute.
##    This variable should usually be passed from the 
##    commandline.
##    
##        -e xtoph_deploy_cmd="[deploy | undeploy | redeploy | setup]"
##
##



##
##    First, need to set up the deployhost with
##    needed software, services and settings
##



- hosts: myDeployhost
  tasks:

    - debug: msg="**** BEGIN SETUP  ****"

    - include_role: 
        name: xtoph_deploy
      vars: 
        xtoph_deploy_action: "setup"
      when: xtoph_deploy_cmd == "setup" or
            xtoph_deploy_cmd == "setup+"

##
##    Second, for libvirt based platform hosts 
##    we need to:
##      - possibly deploy the baremetal node, and
##      - install software, services and settings
##    on the remote hosts (not on the deploy host)

##
##     For the xtoph_ocp4, there are

##       2) bootstrap
##       3) masters
##       4) workers
##
##     NOTE: 'serial: #' limits concurrent 
##           deployments and resolves problems
##           related to disk space and i/o
##           limits
