The Toolforge admins would like to invite all Toolforge Kubernetes users to begin migration of their tools to the 2020 Kubernetes cluster. Instructions for migration and other details are on Wikitech [0].

Timeline: * 2020-01-09: 2020 Kubernetes cluster available for beta testers on an opt-in basis * 2020-01-24: 2020 Kubernetes cluster general availability for migration on an opt-in basis * 2020-02-10: Automatic migration of remaining workloads from 2016 cluster to 2020 cluster by Toolforge admins

We announced beta testing for this new cluster on 2020-01-09 [1]. Since then more than 70 tools have migrated, with approximately 110 tools now using it [2]. The Toolforge admins have also fixed a few small issues that our early testers noticed. We are now ready and excited to have many more tools move their workloads from the legacy Kubernetes cluster over to the new 2020 Kubernetes cluster.

Thanks to Legoktm, Magnus, and others who helped during the beta testing phase by trying things out and reporting issues that they found.

For most tools the migration requires a small number of manual steps [0]: * webservice stop * kubectl config use-context toolforge * alias kubectl=/usr/bin/kubectl; echo "alias kubectl=/usr/bin/kubectl" >> $HOME/.profile * webservice --backend=kubernetes [TYPE] start

This could also be a good opportunity for tools to upgrade to newer language runtimes such as php7.3 and python3.7. See the list on Wikitech [3] for currently available types. When upgrading to a new runtime, do not forget to rebuild Python virtual environments, NPM packages, or Composer packages if you are using them as well.
