- pull incore-tst, incore-dev, incore-prod cluster gitlab
- change directory to target cluster (under terraform directory)
- modify terraform.tfvars
- add the line network_plugin = "canal" under #Kuberentes section
- terraform fmt
- git commit -m "changed from weave to canal" terraform.tfvars
- git push
- go to https://git.ncsa.illinois.edu/kubernetes/clusters/incore-prod and check the process
- wait until process is done
- kubectl config use-context incore-*
- check if canal is running by kubectl get po -n kube-system
- kubectl -n kube-system delete daemonset/weave-net configmaps/weave-net roles/weave-net rolebindings/weave-net controllerrevisions/weave-net clusterrolebindings/weave-net clusterroles/weave-net
- ssh to all the nodes (work node first, then control plain node) - use somaek
- sudo -s
- apt update
- apt -y dist-upgrade
- reboot
- you can check by watch -n 1 kubectl get no -o wide
The weave support will end so the kuberentes network should be switched to canal in tst cluster
