Mao Geng created MESOS-6169: ------------------------------- Summary: --docker_config doesn't work with amazon-ecr-credential-helper Key: MESOS-6169 URL: https://issues.apache.org/jira/browse/MESOS-6169 Project: Mesos Issue Type: Bug Components: docker Affects Versions: 1.0.0 Reporter: Mao Geng
We are using AWS ECR as docker registry and using https://github.com/awslabs/amazon-ecr-credential-helper to get credential automatically. As amazon-ecr-credential-helper required, we set a .docker/config.json file like below: {code} { "credsStore": "ecr-login", "auths": { "xxxxxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com": { } } } {code} According to the "credsStore" field, docker engine will invoke a "docker-credential-ecr-login" command (which we've installed into /usr/bin/) to get registry credential whenever required, for example when executing docker pull/push. This works fine when we tar the .docker/config.json and use uris prarameter to pull the tar.gz file for every task using docker image. But when I try the new --docker_config option, it doesn't work. The task failed to pull the image from ECR. The error message is {code} Failed to launch container: Failed to run 'docker -H unix:///var/run/docker.sock pull xxxxxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/<image_name>:latest': exited with status 1; stderr='WARNING: Error loading config file:/tmp/28Vd2O/.dockercfg - The Auth config file is empty unauthorized: authentication required ' {code} Checked the source at https://github.com/apache/mesos/blob/master/src/docker/docker.cpp, but don't understand why above errors message says loading a temp .dockercfg file, which doesn't exist btw. I assume mesos should pull the image using the config.json file I set to --docker_config, right? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
