Ansible Scripts for ILRI Research-Computing Infrastructure

In order for these playbooks to work, your host must:

  • have finished installation, have working networking, have an SSH daemon running
  • have added a provisioning user via kickstart, preseed, or cloud-init
  • have an entry in the private/hosts
  • have a vars file in host_vars/ which defines at least an ansible_host variable

Assuming the above are true, you should be able to run these playbooks successfully.

Post-install Ansible Invocation

Take note that the first-ever invocation after the clean installation of a machine is different than subsequent invocations due to the way SSH public keys are copied to the host.

On the first run, you need to use -k --ask-become-pass to prompt for the SSH/sudo password of the provisioning user:

$ ansible-playbook site.yml --limit=ilrinrb10 -k --ask-become-pass -t sshd,ssh-keys,sudoers

On subsequent runs, after SSH keys and sudo configurations have been deployed, you should be able to run like this:

$ ansible-playbook site.yml --limit=ilrinrb10

TODO

  • Update: sysctl.conf template for Ubuntu, using CentOS template as a reference
  • Update: make SSH rate limits configurable
