Confirmed: we will use this meeting to cover both the integration/PDAC and science validation/SV/Kubernetes-Commons instance of the Science Platform. I will think about whether a name change is needed (e.g. "LSP Integration and Deployment" meetings?).
Configured and set up. Adam has "kicked the tires". Persistent storage has been set up and configured. Jellybean home directories are available. Anyone with NCSA credentials can log in. Jellybean home is available from lsst-dev. Includes a Docker registry. The registry should already be accessible from the PDAC nodes.
Did not end up using Samba for the home directory setup. Just plain NFS.
Not planning to bring up Qserv during this cycle.
Brian Van Klaveren interested in bringing up imgserv on the commons, able to see Butler repositories on /datasets. Can also bring up dbserv looking at a database on lsst10.
Andrew Loftus has been working on this. All of the node rework looks like it will be done by next week. Will probably federate the cluster and then roll out the configuration to the rest of the DB nodes. See .
Existing Docker-deployed DAX services will continue to run for now. Will announce when it is time to switch to the Kubernetes-deployed services.
Note that the Kubernetes Commons registry is available for PDAC use.
Michelle Butler reports that staff have suggested using the same head node as for the Kubernetes Commons. Currently it's a bare metal machine. Apparently a node could be shared. Discussion leads to decision that we'll spin up a new VM for this instead in the LSST VM infrastructure.
Fritz Mueller will make a ticket with the requirements for a Kubernetes head node VM for PDAC -
Discussion of how to provide Jellybean / Notebook Aspect services in PDAC: minimum requirements are for a pod for the JupyterHub service and a pod per user. Will not need a storage pod in PDAC if the same approach to GPFS/NFS integration is taken that was used in the Kubernetes Commons. Additional pods needed for logging and for container image pre-loading.
Tentative decision: Use SUIT load-balancer node for now for the necessary pods; request a VM if this is found not to be adequate
Will discuss the overall plan for getting PDAC services out from behind the VPN ( a: security signoff; and b: meaningful login and authorization) two weeks from today at PDAC meeting in preparation for May DMLT and F18 cycle planning.
