Hi Frank, thanks for the video. I just followed the steps you demonstrated and everything went fine. However, when I tried to join the second master and ran kubectl get nodes, the second master is recognized as a worker, not a control plane. Additionally, I wasn't able to execute these commands: mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config thanks again Ryad
@@escanorsama7922, please check the version of Ubuntu you are using.... In this setup i have used Ubuntu version 20.04. This version should resolve any issue you are having...

@@frankteachesdevops tkx for the reply i am using Ubuntu 2404 so i think iam good no?
But if Haproxy machine off - everything fall down too... so what`s profit of multiple master with such config
Why are you so interested in the HaProxy going down?..
There is another setup that makes use of two-HAProxies....
How the ETCD will behave
when some cluster falls, the "HA" doesnt work, so its like to have 1 cluster, this video doesnt work for HA with K8s+Haproxy
@dex11514 Really? My bad :/ I did install HAProxy with Kubernetes, but I am stuck on joining the second master.
