Ansible Guide¶

Before you start, see the configuration section. There are some thing you need to setup first.

First, create an inventory file for the environment. There are three categories: masterservers, crafternodes and hlrs. The first category will deploy a RayCrafter Master Server. The second will setup a note that has ssh access to the cluster and submits jobs or transfers data. The third will setup everything at the cluster.

For example create a file hosts with the content:

# content of hosts inventory file
[masterservers]
141.62.110.219 ansible_ssh_user=useronserver

[crafternodes]
141.62.110.220 ansible_ssh_user=useronserver

[hlrs]
hornet.hww.de ansible_ssh_user=hlrsaccountname

Run the main playbook sites.yml, which includes the production and hlrs playbook:

$ ansible-playbook -i hosts sites.yml --ask-vault-pass

If you’re testing with vagrant, and the VM is already running, you can use this command:

$ vagrant provision
