k8s – google 產生 node 方式

google 產生 node 方式

google 產生 node 方式

1. 產生 node 機器(共三台)，到 gcp (kubernetes engine) → 新增節點集區→ 填名稱→節點調整為 1 → 調整 cpu x2 ram 4G → 管理 關閉啟用自動升級功能/以及啟用自動修復功能

2. 到 devops-k8s-prod/geo1~x/底下編輯 deploy.yml and service.yml
   deploy.yml 修改  
   有關 name: geo1 (要改的名稱) and nodeSelector: geo-slave-node-1 對應

   apiVersion: extensions/v1beta1
   kind: Deployment
   metadata:
     name: geo1
   spec:
     replicas: 1
     strategy:
       type: RollingUpdate
       rollingUpdate:
         maxSurge: 1
         maxUnavailable: 1
     minReadySeconds: 5
     template:
       metadata:
         labels:
           name: geo1
           env: production
           color: blue
       spec:
         hostNetwork: false
         nodeSelector:
           cloud.google.com/gke-nodepool: geo-slave-node-1
         containers:
         - name: geo1
           image: asia.gcr.io/-174006/geo:v0.6.1
           imagePullPolicy: Always
           ports:
           - containerPort: 8106

3. 修改完執行 kubectl apply -f deploy.yml 。請看 pod 是否正常
   

   kubectl get pod | grep geo (deploy.yml)
   geo-b8d87f6dd-fktwr                          1/1     Running       0          18d
   geo-blue-74ffc77f69-vj8gl                    1/1     Running       0          17d
   geo1-78754b7f8b-tzbkg                        1/1     Running       0          174m
   geo2-5d6f8d8cc5-m698v                        1/1     Running       0          25m
   geo3-7ccf7594bd-vzd79                        1/1     Running       0          25m
   geo4-555f974fdf-lscmt                        1/1     Running       0          156

4. service.yml 修改
   有關 name: geo1 (要改的名稱)
   

   apiVersion: v1
   kind: Service
   metadata:
     name: geo1
   spec:
     type: NodePort
     ports:
       - name: geo1
         protocol: TCP
         port: 8106
         targetPort: 8106
     selector:
       name: geo1
       env: production
       color: blue

5. 修改完執行 kubectl apply -f service.yml 。請看 pod 是否正常
   

   kubectl get service | grep geo
   geo                   NodePort       10.23.241.223               8106:31422/TCP                                 622d
   geo-blue              NodePort       10.23.253.176               8106:31244/TCP                                 31d
   geo1                  NodePort       10.23.246.55                8106:31259/TCP                                 172m
   geo2                  NodePort       10.23.244.199               8106:31907/TCP                                 12d
   geo3                  NodePort       10.23.247.234               8106:30136/TCP                                 20h
   geo4                  NodePort       10.23.248.128               8106:32107/TCP                                 146m

6.  登入 kong → APIS → 修改NAME geo-for test → Uris /geo1/v1 → https://geo1:8106
   測試是否正常運作
   

   https://api.xxxxx.com/geo1/v1/get_geo_info/?ip=115.178.180.42&apikey=ywhYbFyanJIr0q9xeJezgU884STJpoxu

7. 確認沒問題，加入 upstreams → geos DETAILS → Targets → 把 geo1 內網ip加進去
