Ironic template does not work

[yuanying]

Template definition doesn't support ironic template.
So we should add new template definition class for ironic.

Hi YuanYing,

I understand magnum call heat to deploy vm/bm, and heat will call nova to boot bm via ironic, so dont think we need an special heat template to boot bare metal for magnum, correct me if I am wrong understanding, any comments?

Thank you.

Right, but currently it doesn't work.

Use this to track that. As it is a not simple issue.

    Fix ironic template

    This is workaround fix to support baremetal.
    Following items are remained to support.
    * Documents
    * Functional test

    To test this template, there are some requirements and problem as below.

    Requirements:
    * `ephemeral_disk` on ironic baremetal flavor
      `ephemeral_disk` is used for docker storage instead of cinder volume.

    * `fixed_subnet` must be setup with dns_nameservers like following.
        * `neutron subnet-update private-subnet --dns-nameserver 8.8.8.8`

    * `fixed_subnet` must be IP version 4.
      if you use devstack, please add following configuration.
        * `IP_VERSION=4`

    * Fedora 23 image including kubernetes, etcd, flannel.

    Problem:
    Ironic stores `instance_info` about nova instance.
    `instance_info` contains config_drive data, but this data can be
    too large to store ironic.nodes table.
    Magnum uses large config drive data to setup k8s.
    It means, we can not start ironic instance by Magnum.

    Workaround fix is changing column type of ironic.nodes.instance_info.
    Following sql will help you.

      `alter table ironic.nodes modify instance_info LONGTEXT;`
