Question

我试图将映像从我的私有注册表（港口）部署到我的Kubernetes环境。注册表已成功设置，并且已经包含我的图像。

要提供上下文信息，这是我的部署文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    name: sps-app
  name: sps-app
spec:
  replicas: 1
  template:
    metadata:
      labels:
        name: sps-app
    spec:
      containers:
      - image: repo-harbor.test.com/sps_project/spsapp:23
        env:
        - name: MONGODB_URL
          value: "mongodb://mongo.default.svc.cluster.local:27017/user"
        name: sps-app
        ports:
        - containerPort: 4000
          name: sps-app
      imagePullSecrets:
      - name: harbor

我已经使用以下命令创建了港口秘密

kubectl create secret docker-registry harbor \
--docker-server=https://repo-harbor.test.com \
--docker-username=admin \
--docker-password='xxxxxx!'

但是，当我进行部署的kubectl apply -f时，总是会发生映像拉回。

进一步调查后，我检查了Pod的日志，并指出存在x509认证错误。

目前，我不确定如何解决此问题。谁能解决这个问题？

Answer 1

根本原因

jur01-harbor.acepod.com上的映像注册表使用Docker不信任的自签名证书。

解决方案

将该映像注册表提供的自定义CA证书复制到您的所有Kubernetes节点的/etc/docker/certs.d/jur01-harbor.acepod.com/目录中。

参考：Docker docs / Test an insecure registry。

Kubernetes没有从私有注册表中提取图像
