Tiago:

• Microservices:
  • Timezone in the run registry seems wrong, returns Geneva time, but labels it as GMT
    • Alessandro: What does `date` say in the container?
      • Tiago tested and it doesn't work (command not found)
    • Alessandro: Try to build the image on the docker building VM
    • Pierre: Pip had a similar problem I think long time ago with the DQM
  • Disconnection from the DB
    • Every 24 hours, the API disconnects from Oracle DB, this causes the first access to the microservice to fail and sends an exception. Subsequent call work
    • Fixed by using some SQLAlchemy magic
• K8s PM:
  • Running K8s for nanorc
  • New release candidate K8sPM hasn't been tested.
  • K8s DAQ cluster was rebuild, it needs to be tested.
• Daphne:
  • Created custom command from the configuration
