[DevOps] Fix Jenkins AirGap Groovy Scripting

[irishgordo]

Pipeline is failing, during harvester-installer step where we get the repo then use the node to build the artifacts fresh (instead of gathering from some hosted endpoint)

Fix:

+ git checkout origin/master
Previous HEAD position was a71e111 testing: Test
HEAD is now at 746783b remove --kill-who flags
+ git pull upstream master
From https://github.com/harvester/harvester-installer
 * branch            master     -> FETCH_HEAD
+ git checkout feat/airgap-harvester-airgap-rancher-install-test
Previous HEAD position was 746783b remove --kill-who flags
Switched to branch 'feat/airgap-harvester-airgap-rancher-install-test'
+ git merge origin/master
Committer identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

Trying just a fix with:

jenkins@jenkins-test-ci:~/workspace$ git config --global user.email "jenkins@jenkins-test-ci.harvesterhci.io"
jenkins@jenkins-test-ci:~/workspace$ git config --global user.name "Jenkins AirGapTesting"

To act as a temporary band-aid for the time being, tbd if it works...

[irishgordo]

Since jenkins is a service user on the node after setting just validated with:

jenkins@jenkins-test-ci:/home/ubuntu$ git config --get user.email
jenkins@jenkins-test-ci.harvesterhci.io
jenkins@jenkins-test-ci:/home/ubuntu$ git config --get user.name
Jenkins AirGapTesting

The pipeline is doing some work to rebase from the feature branch of harvester-installer onto the main/master branch, pretty sure that's why it's needing to have "who's writing this commit".

Ultimately, the harvester-installer fork's feature branch will get merged in upstream to hopefully solidify this as a non-issue.
But again, just as a testing band-aid right now, applying this fix manually/ad-hoc...

[irishgordo]

And again we need all the Dapper/Docker/CMake/Go/Compling based things to build the artifacts since we leverage harvester-installer, therefore currently Jenkins is not containerized/pod-afied on the node because of that...

Moved to automation test implement - but really this is an adhoc edit/band-aid that will need further improvement...
