Wordpress+Mysql 部署不从另一个池中获取 IP 地址

Question

我的部署是关于 Wordpress 和 MYsql。我已经定义了一个新的池和一个新的命名空间，我试图让我的 pods 从这个定义的新池中获得一个 IP 地址，但他们从来没有得到一个。

我的命名空间文件yaml

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

我的矿池代码

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，我还为每个服务（mysql 和 wordpress）准备了两个 PV yaml 文件。

当我执行任何部署的 Kubectl 时，它们停留在 ContainerCreating 并且 IP 列停留在 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 Internet 的指南，例如：https://www.projectcalico.org/calico-ipam-explained-and-enhanced/ 但即使这样在我的实验室也不起作用。

我是 Kubernetes 的新手，我不知道还能做什么或检查什么。

根据此处的 Project Calico 文档，您的错误是由于 YAML 中的无效值造成的：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\"]"

Wordpress+Mysql 部署不从另一个池中获取 IP 地址

Wordpress+Mysql deployment don't get IP address from another pool

mysql

wordpress

calico

kubernetes

cni
