从Kubernetes的私人注册表中抽出图像 [英] Pulling images from private registry in Kubernetes

问题描述

我已经建立了运行在CoreOS上的多容器荚的4节点kubernetes群集。图像来自公共和私人存储库。现在我必须登录到每个节点，并在每次更新它们时手动下拉图像。我想要能够自动拉出来。

1. 我已经尝试在每个服务器上运行docker登录，并将.dockercfg文件放在/ root和/ core


2. 我也用.docker / config.json


3. 做了上面的工作我已经向kube master添加了秘密，并添加了imagePullSecrets ：
   
   
   
   
   • name：docker.io到Pod配置文件。
   
   

当我创建pod时，我收到错误消息错误：

  image< user / image>：最新未找到
  

如果我登录并运行docker拉会拉扯图像。我已经尝试过使用docker.io和quay.io。

解决方案

Kubernetes支持一种特殊类型的秘密，你可以创建将用于为您的pod获取图像。更多详细信息： http://kubernetes.io/ v1.0 / docs / user-guide / images.html＃specified-imagepullsecrets-on-a-pod

I have built a 4 node kubernetes cluster running multi-container pods all running on CoreOS. The images come from public and private repositories. Right now I have to log into each node and manually pull down the images each time I update them. I would like be able to pull them automatically.

1. I have tried running docker login on each server and putting the .dockercfg file in /root and /core
2. I have also done the above with the .docker/config.json
3. I have added secret to the kube master and added imagePullSecrets:
   • name: docker.io to the Pod configuration file.

When I create the pod i get the error message Error:

image <user/image>:latest not found

If I log in and run docker pull it will pull the image. I have tried this using docker.io and quay.io.

解决方案

Kubernetes supports a special type of secret that you can create that will be used to fetch images for your pods. More details here: http://kubernetes.io/v1.0/docs/user-guide/images.html#specifying-imagepullsecrets-on-a-pod
