Hi @Sergey_Pronin , Thanks for you reply.
I tried to follow what @matthewb propose and I decided and move my PCX setup outside Kubernetes.
I’m following the documentation Installing Percona XtraDB Cluster - Percona XtraDB Cluster, and I believed that I missed something that cannot figure it out.
I opened a new topic with what got so far here Extra Node on PCX not starting (not sure if it’s already available).
