AC&T Lab Cluster management config

AC&T HPC Cluster

ansible playbooks

Set up

• Install ansible: apt install ansible

  • To run the mariadb role, a plugin is required: ansible-galaxy collection install community.mysql

• Git-clone this repo on /root

• Make sure that the root account can ssh into all nodes using its ssh key, so no password will be entered. This can be tested by: ansible cluster -m ping, where cluster is the name of the cluster, e.g. apollo, hades.

• We structure the jobs here by playbooks and roles. A playbook can include multiple roles. The roles are defined in the roles/ directory. The playbooks are the *.yml files in this directory.

  • To run a playbook: ansible-playbook playbook.yml
  • To run a role: ansible hades -m include_role -a name=role

Where are the stuff?

Note: the role x means that the item is not managed by any roles

The table is generated by writing # manages: comments in the role files and running update-table.
