Create packer image CD pipeline

added Sprint 22-19 label

marked this issue as related to #22 (closed)

steps to be done in CD pipeline:

• Get the old instance ID
• Start a new instance with knightly built image
• Disassociate old floating IP from the old knightly instance
• Associate it with the new instance
• Delete the old instance

I have chosen the following floating IPs for the Knightly instance:

| 138.26.48.47 | OOD Knightly instance |  |  | ood-knightly 10.250.0.116 | uab-campus     | Active |  |
|--------------|-----------------------|--|--|---------------------------|----------------|--------|--|
| 172.20.10.9  | OOD Knightly instance |  |  | ood-knightly 10.250.0.116 | cheaha-cluster | Active |  |

The CD pipeline will first delete the old instance if there's one, so the floating IPs can be associated with the new instance. And then, it will start a new instance with the nightly build image, and attach the floating IPs to it.

The deploy pipeline will only run on scheduled pipelines.

Now that the CD pipeline is done, we can merge the PR: !10 (merged)

But before we accept it, we need to:

• Change deploy target branch to main, currently set to feat-gitlab-ci for development.
• Setup CICD variables in rc/packer-openstack-hpc-image repo

To build a docker image: https://docs.gitlab.com/ee/user/packages/container_registry/#build-and-push-by-using-gitlab-cicd

Had been struggled with using cache/artifacts between jobs in the pipeline. After @jpr suggested, merged all the jobs into one to eliminate the need to pass cache/artifacts around, and build a custom docker image to save time on installing packages.

Added the Dockerfile for current pipeline image in repo:

!18 (merged)
