Question

我想用马拉松部署一个docker容器，如果没有授权的docker镜像，图像可以正常拉，但是当我尝试从存储库中提取需要授权的图像时，任务部署失败，响应是

Failed to launch container: Failed to run 'docker -H unix:///var/run/docker.sock pull example.com/web:laest': exited with status 1; stderr='Error response from daemon: repository example.com/web not found: does not exist or no pull access '

我将/var/run/docker.sock文件的权限更改为节点上的777，并且掌握，但问题仍然出现，似乎权限不是问题的根本原因;我尝试在节点上运行“docker login”，然后手动拉动图像，然后马拉松任务正确运行，我的马拉松json如下所示：

{
  "id": "/web",
  "cmd": "docker login --username='sam' --passwoer='123456' example.com/web:latest",
  "cpus": 0.3,
  "mem": 32,

   },

      }
   ],

        "labels": {}
      }
    ],

    "parameters": [
      {
        "key": "add-host",

    ],

如何通过马拉松授权拉动图像？

Answer 1

您应该阅读：https://mesosphere.github.io/marathon/docs/native-docker-private-registry.html

按照步骤1，在步骤2中用{/ 1>替换uris部分

"fetch" : [
{
    "uri" : "https://path.to/file",
    "extract" : true,
    "outputFile" : "dockerConfig.tar.gz" 
  }
]

我在这里写了更详细的解释：http://blog.itaysk.com/2017/05/22/using-a-custom-private-docker-registry-with-marathon
