ansible How To Create A DreamHost Cloud Server From An Ansible Playbook Write a Playbook to Launch a Server


Example

Create a file named launch-server.yaml, that will be our playbook.

The first part of the playbook is a list of hosts that your playbook will run on, we only have one, localhost.

- hosts: localhost

Then we need to define a list of tasks to perform in this playbook. We will only have one that launches an Ubuntu Xenial server on DreamCompute.

tasks:
  - name: launch an Ubuntu server

Next part of the playbook uses the os_server (OpenStack Server) module. This defines what the server has to look like in DreamCompute.

os_server:

First step is to authenticate to DreamCompute; substitute {username} with your DreamCompute username, {password} with your DreamCompute password, and {project} with your DreamCompute project. You'll find those in the OpenStack RC file.

  auth:
    auth_url: https://iad2.dream.io:5000
    username: {username}
    password: {password}
    project_name: {project}

Next lines define some elements of the new server.

  state: present
  name: ansible-vm1
  image: Ubuntu-16.04
  key_name: {keyname}
  flavor: 50
  network: public
  wait: yes

Lets break down the previous few lines:

  • state is the state of the server, possible values are present or absent
  • name is the name of the server to create; can be any value
  • image is the image to boot the server from; possible values are visible on DreamHost Cloud web panel; the variable accepts either image name or UUID
  • key_name is the name of the public key to add to the server once it is created; this can be any key has already been added to DreamCompute.
  • flavor is the flavor of server to boot; this defines how much RAM and CPU your server will have; the variable accepts either the name of a flavor (gp1.semisonic) or the ID (50, 100, 200, etc)
  • network is the network to put your server on. In DreamHost Cloud case it is the public network.
  • wait set to yes forces the playbook to wait for the server to be created before continuing.
