Deploy the Discuz forum using K8S and access it using the Nginx proxy

system structure drawing：

​

Pull images：

docker pull mysql:5.7.22
docker pull skyzhou/docker-discuz

Deploy mysql service：

kubectl apply -f mysql-dp.yml
kubectl apply -f mysql-svc.yml

Verify Mysql：

• Obtain the mysql SVC, Record the cluster-ip (172.16.254.96) of mysql-service, and configure this IP when creating a link with discuz SVC

kubectl get svc -o wide

​

• get mysql pods name

kubectl get pods -o wide

• sign in mysql

kubectl exec -it mysql-5f87f4495c-9stsn  -- mysql -uroot -proot
