+
+This is a rough skeleton of the ansible used to deploy RISELab/Apache Spark
Jenkins build workers on Ubuntu 20LTS.
+
+WARNING: this will not work "directly out of the box" and will need to be
tweaked to work on any ubuntu servers you might want to try this on.
+
+### deploy a new worker node
+#### TL;DR:
+all of the configs for the workers live in roles/common/... and
roles/jenkins-worker...
+
+#### prereqs:
+* fresh install of ubuntu 20
+* a service account w/sudo
+* python 3, ansible, ansible-playbook installed locally
+* add hostname(s) to the `hosts` file
+* add this to your `~/.ansible.cfg`:
+```[defaults] host_key_checking = False```
+
+#### fire ansible cannon!
+`ansible-playbook -u <service account> deploy-jenkins-worker.yml -i
<ansible-style-hosts-file> -k -b -K`
+
+tips:
+* if you are installing more than a few workers, it's best to run the playbook
on smaller (2-3) batches at a time. this way it's easier to track down errors,
as ansible is very noisy.
+* when you encounter an error, you should comment out any previously-run plays
and tasks. this saves time when debugging, and let's you easily track where
you are in the process.
+* `apt-get remove <application_name>` and `apt-get purge <package-name>` are
your friends
