如何从 Vagrant 上的 Kubernetes 访问私有 Docker Hub 存储库
我无法从我的私有 Docker Hub 存储库中提取到在 Vagrant 上运行的本地 Kubernetes 设置:
I am failing to pull from my private Docker Hub repository into my local Kubernetes setup running on Vagrant:
podhellonode-n1hox"中的容器hellonode"正在等待启动:图像不能拉
Container "hellonode" in pod "hellonode-n1hox" is waiting to start: image can't be pulled
无法拉取镜像用户名/hellonode":错误:镜像用户名/hellonode:最新未找到
Failed to pull image "username/hellonode": Error: image username/hellonode:latest not found
我已经按照此处的描述在本地通过 Vagrant 设置了 Kubernetes 并创建一个名为dockerhub"的秘密,使用 kubectl 创建秘密 docker-registry dockerhub --docker-server=https://registry.hub.docker.com/ --docker-username=username --docker-password=... --docker-email=... 我提供了它作为图像拉取密码.
I have set up Kubernetes locally via Vagrant as described here and created a secret named "dockerhub" with kubectl create secret docker-registry dockerhub --docker-server=https://registry.hub.docker.com/ --docker-username=username --docker-password=... --docker-email=... which I supplied as the image pull secret.
我正在运行 Kubernetes 1.2.0.

从 Kubernetes YAML 中提取私有的 DockerHub 托管镜像:
To pull a private DockerHub hosted image from a Kubernetes YAML:
运行这些命令:
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
,并且您的私有仓库名为 PRIVATE_REPO_NAME
,并且您要拉取的镜像被标记为 latest
>,创建这个 example.yaml
文件:
If your username on DockerHub is DOCKER_USER
, and your private repo is called PRIVATE_REPO_NAME
, and the image you want to pull is tagged as latest
, create this example.yaml
file:
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
