EOS-5

Moving all our deployment and dev work to EOS-5 is needed. Usage of EOS-4 should be avoided across our entire dev and deployment stack.

Important topics for EOS-5:

• Deployment to production
• Buildup tree scrips (dev setup)
• Using EOS-5 on CI with HTTPS (requires certificates)
• Removing support for EOS-4 (change stagerrm to evict?)

Future changes in CTA dev team

• Lasse and Vova are leaving soon :( Many thanks!!
• Dev team will need reinforcements (Pablo, Richard?)

Review last tasks. Discuss handover strategy.

Some possible tasks for the "newcomers":

• Keep cta-taped alive if at least one drive handler is alive #303
• Migration of CTA system tests (and other scripts) from Bash to Python.

"Needs discussion" topics

• Issues link

"Dev issue needed" topics

• Ops issues link

PostgreSQL scheduler DB

• Knowledge has been passed from David to Jaroslav
  • Jaroslav will drive this from now on, and discuss with David only when necessary
• Strategy:
  • Setup a new dev machine with the new scheduler
  • Follow the cycle of a request and start doing the changes one-by-one
• Jaroslav has not started working on yet, just setting up the requests
• Jaroslav will work on #5 as well

EOS-5

• There is a replacement proposal for the build tree, to be discussed between Jorge, Julien and Richard: Issue #372
  • Discussion and implementation to be working in 2 weeks from now.
