      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.

      Relevant topics:

      • Deployment to production
      • Buildtree replacement proposal #372
      • Setting up certificates on CI for HTTPS

      CI update tasks

      Richard has been working on a plan:

      CMS fails to rm files in eosctacms

      "Needs discussion" topics

      "Dev issue needed" topics


      Deployment to Prod

      • Deployment in progress.
      • Jaroslav is working on puppet configuration, which will then be tested in pps. Knows how to do it in EOS, but needs to learn how to do with CTA.
      • One CTA instance will be migrated per week.

      Buildtree replacement

      • Jorge is progressing on this work.
      • Hopes to have a merge request next week, before which the team members will be invited to test the new dev environment.
      • Jorge will update the documentation on how to do this.
      • This is an important blocker for EOS work, that needs to be unblocked.
