系統環境準備 

## 安裝 Helm3
$ curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash

## 安裝 NFS
$ sudo apk -U add nfs-utils

## 設定 NFS Server
$ sudo rc-update add nfs
$ sudo mkdir /opt/www; sudo chown -R nobody:nogroup /opt/www
$ echo "/opt/www *(rw,sync,no_subtree_check,no_root_squash,no_all_squash,insecure)" | sudo tee /etc/exports

## 啟動 NFS Server
$ sudo rc-service rpcbind start
$ sudo rc-service nfs start

## Kind M109 設定
$ echo 'fs.inotify.max_user_instances=512
fs.inotify.max_user_watches=262144' | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

$ sudo podman exec c30-worker bash -c "systemctl restart rpcbind.service && \
rm -f /lib/systemd/system/nfs-common.service && \
systemctl daemon-reload && \
systemctl restart nfs-common.service"

$ sudo podman exec c30-worker2 bash -c "systemctl restart rpcbind.service && \
rm -f /lib/systemd/system/nfs-common.service && \
systemctl daemon-reload && \
systemctl restart nfs-common.service"

# 建立 Namespace
$ kubectl create ns nfs-provisioner

## 安裝與建立 NFS Provisioner
$ helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/

$ helm repo update

$ helm -n nfs-provisioner install mynfs nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
--set storageClass.defaultClass=true \
--set storageClass.name=mynfs \
--set nfs.server=192.168.61.128 \
--set nfs.path=/opt/www

$ kubectl -n nfs-provisioner get pods
NAME                                                     READY   STATUS    RESTARTS   AGE
mynfs-nfs-subdir-external-provisioner-768545df76-7xzxc   1/1     Running   0          10s

## 設定 Node Label
$ kubectl label node c30-worker run=bobo

## 建立 MySQL NDB Operator
$ helm repo add ndb-operator-repo https://mysql.github.io/mysql-ndb-operator/

$ helm repo update

$ helm install ndb-operator ndb-operator-repo/ndb-operator --namespace=mysql-operator --create-namespace

$ kubectl -n mysql-operator get pods
NAME                                           READY   STATUS    RESTARTS   AGE
ndb-operator-app-5b9c84c4bc-6nfhz              1/1     Running   0          106s
ndb-operator-webhook-server-6c4d66d95d-twvzp   1/1     Running   0          106s

開始安裝 bobo 系統 

$ git clone https://github.com/braveantony/bobo.git

## 檢視 bobo 目錄中的檔案

└── svc-fbs.yaml

$ ka -f ./bobo/namespace.yaml

$ ka -f ./bobo

$ kubectl -n bobo get pods

$ kubectl -n mysql get pods

建立 MySQL NDB Cluster 管理者帳號 

$ base64 -d <<< $(kubectl get secret mysql-ndb-mysqld-root-password -n mysql -o jsonpath={.data.password}); echo
JlabTb1jdqUcWY1d

$ kubectl exec -it -n mysql mysql-ndb-mysqld-0 -- bash
