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
