Wordpress+Mysql 部署不从另一个池中获取 IP 地址

如何解决Wordpress+Mysql 部署不从另一个池中获取 IP 地址

我的部署是关于 wordpress 和 MysqL。我已经定义了一个新池和一个新命名空间，我试图让我的 pod 从这个定义的新池中获得一个 IP 地址，但他们从未获得过。

我的命名空间文件 yaml

apiVersion: v1
kind: Namespace
Metadata:
  name: produccion
  annotations:
    cni.projectcalico.org/ipv4pools: ippool

我的泳池代码

calicoctl create -f -<<EOF
apiVersion: projectcalico.org/v3
kind: IPPool
Metadata:
   name: ippool
spec:
   cidr: 192.169.0.0/24
   blockSize: 29
   ipipMode: Always
   natOutgoing: true
EOF

我的MysqL部署是

apiVersion: v1
kind: Service
Metadata:
  name: wordpress-MysqL   
  namespace: produccion
  labels:                 
    app: wordpress
spec:
  ports:
    - port: 3306
      targetPort: 3306
      nodePort: 31066
  selector:
    app: wordpress
    tier: MysqL
  type: NodePort
---
apiVersion:  apps/v1
kind: Deployment
Metadata:
  name: wordpress-MysqL
  namespace: produccion
  annotations:
    cni.projectcalico.org/ipv4pools: ippool
  labels:
    app: wordpress
spec:
  selector:
    matchLabels:
      app: wordpress
      tier: MysqL
  strategy:
    type: Recreate
  template:
    Metadata:
      labels:
        app: wordpress
        tier: MysqL
    spec:
      containers:
      - image: MysqL
        name: MysqL
        env:
        - name: MysqL_ROOT_PASSWORD
          value: PASS
        ports:
        - containerPort: 3306
          name: MysqL
        volumeMounts:
        - name: MysqL-persistent-storage 
          mountPath: "/var/lib/MysqL"
      volumes:
      - name: MysqL-persistent-storage 
        persistentVolumeClaim:
          claimName: MysqL-pv-claim

我的 wordpress 部署

apiVersion: v1
kind: Service
Metadata:
  name: wordpress
  namespace: produccion
  labels:
    app: wordpress
spec:
  ports:
    - port: 80
      nodePort: 30999
  selector:
    app: wordpress
    tier: frontend
  type: NodePort
---
apiVersion: apps/v1 
kind: Deployment
Metadata:
  name: wordpress
  namespace: produccion
  labels:
    app: wordpress
spec:
  selector:
    matchLabels:
      app: wordpress
      tier: frontend
  strategy:
    type: Recreate
  template:
    Metadata:
      labels:
        app: wordpress
        tier: frontend
    spec:
      containers:
      - image: wordpress
        name: wordpress
        env:
        - name: wordpress_DB_NAME
          value: wordpress
        - name: wordpress_DB_HOST
          value: IP_Address:31066
        - name: wordpress_DB_USER
          value: root
        - name: wordpress_DB_PASSWORD
          value: PASS
        ports:
        - containerPort: 80
          name: wordpress
        volumeMounts:
        - name: wordpress-persistent-storage
          mountPath: "/var/www/html"          
      volumes:
      - name: wordpress-persistent-storage
        persistentVolumeClaim:
          claimName: wordpress-persistent-storage

此外，我还有每个服务（MysqL 和 wordpress）的两个 PV yaml 文件。

当我执行任何部署的 Kubectl 时，它们保持在 ContainerCreating，而 IP 列保持在 none。

produccion             wordpress-MysqL-74578f5d6d-knzzh             0/1     ContainerCreating   0          70m    <none>           dockerc8.tecsinfo-ec.com 

如果我检查这个 pod，我会得到下一个错误：

normal   Scheduled               88s                             default-scheduler  Successfully assigned produccion/wordpress-MysqL-74578f5d6d-65jvt to dockerc8.tecsinfo-ec.com

我使用了一些来自互联网的指南，例如：https://www.projectcalico.org/calico-ipam-explained-and-enhanced/ 但即使这在我的实验室中也不起作用。

我刚开始使用 Kubernetes，不知道还能做什么或检查什么。

解决方法

根据此处的 Project Calico 文档，您的错误是由于 YAML 中的值无效造成的：Using Kubernetes annotations

您需要提供 IP 池列表作为注释中的值，而不是单个字符串。以下代码段应该适合您。

cni.projectcalico.org/ipv4pools: "[\"ippool\"]"
