Manual

Create `odl:odl` user:group?

Manual

Want a home dir for that user?

Manual

chown ODL's dir to `odl:odl`

Manual

Restart ODL service

Manual

(if only you had systemd support)

Manual

Login and configure Karaf features?

Manual

Port configuration?

Manual

Fine for devs

“don’t unit test your playbook"

“Ansible believes you should not need another framework to validate basic things of your infrastructure”
