Helm Chart Overview

The ska-pst chart is a mono chart that integrates the functionalities of the PST.CORE and PST.LMC applications.

The PST.CORE, consists of the following components. For further configuration information, see the documentation for each component.

• RECV.CORE

• SMRB.CORE

• DSP.DISK and DSP.FT

• SEND.CORE

• STAT.CORE

The PST.LMC refers to all of the Tango infrastructure required for monitoring and controlling the PST.CORE See the SKA PST LMC Documentation for more information.

Production Mode

By default, the ska-pst chart is configured to deploy in production mode, such that

• PST.CORE is deployed through core.enabled: true and is to be waiting for gRPC communication with ska-pst-lmc and

• PST.LMC is deployed through deviceServers.pstLmc.enabled: true with simulation mode turned off

ska-pst:
  # Enable the deployment of the ska-pst chart
  enabled: true

  core:
    # Enable the deployment of the PST.CORE applications
    enabled: true

  deviceServers:
    pstLmc:
      # Enable the deployment of the PST.LMC which controls PST.CORE through gRPC
      enabled: true

Probes are configured to to ping low-pst devices recognised through tango_admin; for example

tango_admin -ping --ping-device low-pst/recv/01

Simulation Mode

The ska-pst chart can be deployed in simulation. To run it in simulation mode, the PST.CORE must be disabled and the simulationMode flags of the PST.LMC must be enabled. The resulting configuration is as follows.

ska-pst:
  core:
    enabled: false
    send:
      enabled: false
    primaryVolumeMount:
      type: nfs

  deviceServers:
    pstLmc:
      simulationMode: 1
