--------------------------------
Summary: DOCKER_IMAGE_PATTERN should support multilayered path of
docker images
Key: YARN-3159
URL: https://issues.apache.org/jira/browse/YARN-3159
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.6.0
Reporter: Leitao Guo
Currently, DOCKER_IMAGE_PATTERN in DockerContainerExecutor can only match
docker images with the path like "sequenceiq/hadoop-docker:2.6.0", which has
only 1 "/" in the path.
{code}
public static final String DOCKER_IMAGE_PATTERN =
"^(([\\w\\.-]+)(:\\d+)*\\/)?[\\w\\.:-]+$";
{code}
In our cluster, the image name have multi layers, such as
"docker-registry.qiyi.virtual:8080/cloud/hadoop-docker:2.6.0", which is
workable when using "docker pull IMAGE_NAME", but can not pass the check of
image name in saneDockerImage().
