Install mysql on k8s

Foreword

The middleware and database in the production environment are deployed outside the container. In the experimental environment, the persistent storage can use a distributed storage system or tag nodes for local storage.

Installation

Set the PV on the k8s-03 node, and label the node with app=mysql-car. In the deploy, nodeSelector selects the node and schedules it on this node.

##kubectl label node k8s-03 app=mysql-car##kubectl get nodes --show-labels |grep mysql## Create ns dedicated databasekubectl create ns mysql-dev
