如何从Kubernetes on Vagrant访问私有Docker Hub存储库

Question

我无法从我的私有Docker Hub存储库拉到我在Vagrant上运行的本地Kubernetes设置:

pod"hellonode-n1hox"中的容器"hellonode"正在等待启动:图像无法拉动

无法提取图像"username/hellonode":错误:图像用户名/ hellonode:最新未找到

我已经在这里通过Vagrant在本地设置了Kubernetes 并创建了一个名为"dockerhub"的秘密,其中包含kubectl创建秘密docker-registry dockerhub --docker-server = https://registry.hub.docker.com/ --docker-username = username --docker-password = ... --docker-email = ...我提供的图像拉秘密.

我正在运行Kubernetes 1.2.0.

Answer 1

从Kubernetes YAML中提取私有DockerHub托管图像:

运行以下命令:

DOCKER_REGISTRY_SERVER=docker.io
DOCKER_USER=Type your dockerhub username, same as when you `docker login`
DOCKER_EMAIL=Type your dockerhub email, same as when you `docker login`
DOCKER_PASSWORD=Type your dockerhub pw, same as when you `docker login`

kubectl create secret docker-registry myregistrykey \
  --docker-server=$DOCKER_REGISTRY_SERVER \
  --docker-username=$DOCKER_USER \
  --docker-password=$DOCKER_PASSWORD \
  --docker-email=$DOCKER_EMAIL

如果您在DockerHub上的用户名是DOCKER_USER,并且您的私人仓库被调用PRIVATE_REPO_NAME,并且您想要提取的图像被标记为latest,则创建此example.yaml文件:

apiVersion: v1
kind: Pod
metadata:
  name: whatever
spec:
  containers:
    - name: whatever
      image: DOCKER_USER/PRIVATE_REPO_NAME:latest
      imagePullPolicy: Always
      command: [ "echo", "SUCCESS" ]
  imagePullSecrets:
    - name: myregistrykey

然后运行:

kubectl create -f example.yaml

Answer 2

创建k8秘密:

apiVersion: v1
kind: Secret
metadata:
  name: repositorySecretKey
data:
  .dockerconfigjson: <base64 encoded docker auth config>
type: kubernetes.io/dockerconfigjson

然后在pod或rc config中提到秘密.示例:

apiVersion: v1
kind: Pod
metadata:
  name: test-pod
spec:
  containers:
    - name: test-pod
      image: quay.io/example/hello:1.1
  imagePullSecrets:
    - name: repositorySecretKey

Docker auth配置

{
   "https://quay.io": {
    "email": ".",
    "auth": "<base64 encoded auth token>"
  }
}

要么

kubectl create secret docker-registry myregistrykey \
    --docker-server=DOCKER_REGISTRY_SERVER \
    --docker-username=DOCKER_USER \
    --docker-password=DOCKER_PASSWORD \
    --docker-email=DOCKER_EMAIL
