TL;DR: yes
Just from a quick view of the repo, the simplest way to do it would be to look at the playbook.yml and copy all roles you want for a host into a new playbook, say myhost.yaml. Copy not only the roles but all the other keywords as well. Then you go to the inventory and add your hosts where you to execute the playbook against. Then you change the hosts key value in the playbook you made from all to the hosts you added to the inventory.
That is, add your hosts to the inventory, create playbooks for for them and run. That is the easiest. Read up on how to do groups and organizing your inventory to improve it from there.




I moved from academia into working with linux. I did some selfhosting before and was well versed in linux. Look for sysadmin or devops roles – I did not know what devops was before I started this. Look for companies that are in process of moving to linux or recently has, they may be looking for increased workforce to handle to move or are in the process of replacing consultants with more permanent staff. Look for companies which have development in C, C++, maybe also rust? Chances are their software ay be running on linux in one way or another, and may need a devops and/or sysadmin. Some banks, companies doing embedded systems, industrial tools and machinery, are examples which fit here that I know of. Might not be the most interesting companies, but the work could be ok.
If you are looking to get a foot in in some open source project, then it is a bit different. I have almost happened to slide into some projects. Use a product, get to know it, read the issues. Maybe closed issues just to find a solved one and try to figure out why that solved it. Start solving open issues. If you think you have something to contribute when a project asks for input, leave a comment. See what sticks. Some projects may take years to get back to you and your contributions, others may ask you to review something after a few weeks if it clicks. That is my feeling at least, but I just have sporadic contributions, more well established folks may have more insight.
