volumes, etc) and it's ip address.
You will then be able to login, as root.
Setting up a new persistent cloud host:
1. select an ip:
sudo -i euca-describe-addresses
- pick an ip from the list that is not assigned anywhere
- add it into dns - normally in the cloud.fedoraproject.org but it doesn't
have to be
2. set up the host/ip in ansible host inventory
- add to ansible/inventory/inventory under [persistent-cloud]
- either the ip itself or the hostname you want to refer to it as
3. setup the host_vars
- create file named by the hostname or ip you used in the inventory
Contents should look like this (remove all the comments)

# what security group to add the host to

# instance id will be appended

4. setup a host playbook ansible/playbooks/hosts/$YOUR_HOSTNAME_HERE.yml
- name: check/create instance
hosts: $YOUR_HOSTNAME/IP HERE
user: root
gather_facts: False
vars_files:
- /srv/web/infra/ansible/vars/global.yml
- ${private}/vars.yml
tasks:
- include: $tasks/persistent_cloud.yml
- name: provision instance
hosts: $YOUR_HOSTNAME/IP HERE
user: root
gather_facts: True
vars_files:
- /srv/web/infra/ansible/vars/global.yml
- ${private}/vars.yml
- ${vars}/${ansible_distribution}.yml
tasks:
- include: $tasks/cloud_setup_basic.yml
# fill in other actions/includes/etc here
handlers:
- include: $handlers/restart_services.yml
5. add/commit the above to the git repo and push your changes
6. set it up:
sudo -i ansible-playbook /srv/web/infra/ansible/playbooks/hosts/$YOUR_HOSTNAME_HERE.yml
7. login, etc
You should be able to run that playbook over and over again safely, it will
only setup/create a new instance if the ip is not up/responding.
