Automating the Openstack VM Creation

Time permitting, we can look at another playbook which can help deploy an instance in Openstack.

Examine the playbook

In a previous module you should have checked out this git repository:

$ git clone https://github.com/TACC/CSC2018Institute.git

This should have created a directory called CSC2018Institute in the current working directory.

Modify the playbook to include your username and the name of the instance you would like to create:

...
  - name: Create a new instance and attaches to a network and passes metadata to the instance
    os_server:
      state: present
      name: your_name_here04
...
      auth: 
        auth_url: https://tacc.jetstream-cloud.org:5000/v3
        username: your_username_here
        project_name: TG-TRA170023

The playbook also requires some small changes to your hosts files. First, put a single the hosts in the openstack_client group by adding

[openstack_client]

at the top of the hosts file with only 1 host underneath it.

Once your hosts file is updated, run the playbook with the command:

$ ansible-playbook -i hosts CSC2018Institute/openstack_client.yml

If all goes well you should see messages similar to:

What is your Openstack Password?: 

PLAY [web_1] ****************************************************************************************************************************
****
...

Once you enter your password interactively, the playbook should run and complete in a couple minutes.

Visit the Openstack Dashboard to verify that your instance was created.
