Base Test Stand

This section contains site specific variations for the Base test stand.

Resources

(1) Need to get kubeconfig file from here. File a Jira ticket with IT for access. Once able to log into Rancher:

  1. Select the manke cluster.
  2. Click the Kubeconfig File button in top-right.
  3. Near bottom of dialog, click the download link.

Non-Production Systems

The Base Teststand operates all CSCs and systems on the production domain.

Bare Metal Machines

  • Main OSPL Daemon: azar01.ls.lsst.org
  • LOVE: love01.ls.lsst.org
  • T&S CSCs: tel-hw1.ls.lsst.org
  • Kubernetes: Can be done from own machine, just need kubeconfig file and kubectl installed.
  • ATCamera (Tony Johnson): auxtel-mcm.ls.lsst.org

LOVE Summary View

The overall system summary state view is called Summary State.

Checking the Number of Federations

This uses a script in https://github.com/lsst-ts/k8s-admin. Run ./feds-check from a machine with kubectl and the proper kubeconfig file.

Shutdown Camera Services

  • Shutdown ATCamera OCS Bridges:
    • sudo systemctl stop ats-ocs-bridge.service
  • Shutdown Camera Daemons
    • sudo systemctl stop opensplice.service

Shutdown LOVE

This needs to be done from love01.

  • Uses the docker-compose-admin scripts in base-teststand/love01 directory, which are are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./shutdown_love
    • ./shutdown_daemon

Shutdown T&S Bare Metal Services

Handle tel-hw1:

  • Uses the docker-compose-admin scripts in base-teststand/tel-hw1 directory, which are are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./shutdown_atmcs_atp
    • ./shutdown_daemon

Interacting with Kubernetes

Commands can be executed from your own machine with kubectl and the proper kubeconfig file.

Shutdown Main Daemon

This needs to be done from azar01.

  • Uses the docker-compose-admin scripts in base-teststand/azar01, which are are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./shutdown_daemon

Update Configuration

  • Gather the branch for the configurations and version number for ts_ddsconfig.
  • Uses the docker-compose-admin/base-teststand/update_repo script, which is linked into the dco user home directory.
  • Repos to update:
    • docker-compose-ops (love01, tel-hw1)
    • LOVE-integration-tools (love01)
    • ts_ddsconfig (love01, tel-hw1) NOTE: Only necessary if there are updates.
  • Become the dco user: sudo -iu dco
  • ./update_repo <repo path> <branch or version>

Startup Main Daemon

This needs to be done from azar01.

  • Uses the docker-compose-admin scripts in base-teststand/azar01 directory, which are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./launch_daemon
    • Ensure daemon is ready before proceeding.

Startup Minimal Kubernetes System

This replaces most of step 6.3 in the main document. Follow the first three bullet points in that step and then continue the process with the next steps.

  • python sync_apps.py -p –no-sync=love
  • NOTE: the –no-sync=love flag will prevent an error regarding resources not existing.
  • csc-cluster-config and ospl-config apps will be synced automatically.
  • Once the ospl-daemon app is synced, the script will pause.
  • Check the logs on Argo CD UI to see if daemons are ready.
  • Type go and enter to move onto syncing the kafka-producers app.
  • Script will again pause once the kafka-producers are synced.
  • The kafka-producers use a startup probe, so once all of the pods show a green heart, stop here and return to step 6.4 in the main document.
  • Make sure you leave the script running.

Startup LOVE

This needs to be done from love01.

  • Uses the docker-compose-admin scripts in base-teststand/love01 directory, which are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./launch_daemon
    • Ensure daemon is ready before proceeding.
    • ./launch_love

Startup Camera Services

This needs to be done from auxtel-mcm.

  • Start Camera Daemons
    • sudo systemctl start opensplice.service
  • Start Camera OCS Bridges:
    • ATCamera: sudo systemctl start ats-ocs-bridge.service
    • Ensure bridge services are running:
      • ATCamera: sudo systemctl status ats-ocs-bridge.service
  • Transition to OFFLINE_AVAILABLE:
    • ATCamera:
      • ccs-shell
      • ccs> set target ats-ocs-bridge
      • ccs> lock
      • ccs> setAvailable
      • ccs> unlock
      • ccs> exit

Startup T&S Bare Metal Services

Handle tel-hw1

  • Uses the docker-compose-admin scripts in base-teststand/tel-hw1 directory, which are linked into the dco user home directory.
    • Become the dco user: sudo -iu dco
    • ./launch_daemon
    • Ensure daemon is ready before proceeding.
    • ./launch_atmcs_atp

Enabled CSCs

If proceeding with integration testing, the CSCs will be brought to ENABLED state as part of that process. All of the startup processes may be necessary for recovering the BTS from any maintenance. The following components will automatically transition to ENABLED state when launched:

  • WeatherForecast
  • ScriptQueue:1
  • ScriptQueue:2
  • DSM:1
  • DSM:2

For the other components, the BTS will be handled in the same way as the Summit. For reference, see Observatory and Control System Guidelines for BTS

Only leverage the following scripts, if necessary. Required configurations will be given for each script execution.

  • set_summary_state.py
