minikube-x509：未知授权机构签署的证书

如何解决minikube-x509：未知授权机构签署的证书

我正在使用minikube和kubectl为RC创建一个mongo。我正在使用公司的VPN。

通过RC命令创建了kubectl create -f ./rc/mongo-rc.yaml。

使用kubectl describe pod mongo-5zttk命令时，在kubernetes事件以下：

...
Events:
  Type     Reason     Age                    From               Message

  Warning  Failed     2m8s (x21 over 7m15s)  kubelet,minikube  Error: ImagePullBackOff

当我尝试使用curl访问URL时：

⚡  curl https://registry-1.docker.io/v2/library/mongo/manifests/latest
{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"repository","Class":"","Name":"library/mongo","Action":"pull"}]}]}

我可以从docker hub注册表中成功提取mongo:latest映像。

⚡  docker pull mongo:latest
latest: Pulling from library/mongo
Digest: sha256:efc408845bc917d0b7fd97a8590e9c8d3c314f58cee651bd3030c9cf2ce9032d
Status: Image is up to date for mongo:latest
docker.io/library/mongo:latest

环境信息：

• minikube版本：v1.14.1
• kubectl
  • 客户端版本：v1.18.8
  • 服务器版本：v1.19.2
• 操作系统：macOS 10.13.6

我已阅读文档：vpn_and_proxy/#x509-certificate-signed-by-unknown-authority。解决方案是向IT部门索取适当的PEM文件。如果无法获取PEM文件，有什么解决方案吗？例如使用一些命令标志：--skip-verify-cert？

更新：

mongo-rc.yaml：

apiVersion: v1
kind: ReplicationController
metadata: 
  name: mongo
spec: 
  replicas: 1
  selector: 
    app: mongo
  template: 
    metadata: 
      labels:
        app: mongo
    spec: 
      containers: 
      - name: mongo
        image: mongo
        ports: 
        - containerPort: 27017
        env: 
        - name: MONGO_ROOT_PASSWORD
          value: "123456"

解决方法

您应该可以使用--insecure-registry标志，但是您可能必须重新创建minikube集群才能使它工作。

minikube start --insecure-registry="registry-1.docker.io"
