How to access

ad-build-dev cluster: https://k8s.slac.stanford.edu/ad-build-dev

ad-build cluster: https://k8s.slac.stanford.edu/ad-build

  1. After following the commands in those links, you will need to request access to the cluster from Claudio.
  2. Recommended to install k9s tool https://k9scli.io/topics/install/

Other Notes

  1. Kubernetes cluster is intended to be just for build system. 
  2. Can use local machine or nodes in the kubernetes cluster to create docker images (Don't need access to s3df/afs filesystem if all modules/dependencies are uploaded to GitHub, as they should be)
  3. Docker can be ran on local machine, but not on s3df, it is intended to use apptainer instead, if build enviornment wants to be passed around. So when this build system is finished, developers/users won't use docker directly, instead will use apptainer and pull docker images from artifact storage (if needed)
