master workspace is /home/jenkins_home/workspace

slave workspace is /home/jenkins/workspace

i can find /home/jenkins/workspace/71bnh8co385ctlmoxgbumdnpnet3ywq directory in slave node。

i guess this build in master node,but i see the task in slave queue

Answer 1

jenkins docker-build-step插件不支持在从属节点上运行任务，因此您可以更改一些代码以支持它。向slave添加一个jar可以创建映像并推送映像。然后master在slave上调用此jar

Answer 2

Not sure if that's the case here, but it seems that Jenkins sets a path to Dockerfile in Docker build/create task at Build stage as $WORKSPACE/docker so you either have to ensure you have that folder (containing Dockerfile and other needed files) in your workspace/git repo or just remove docker from path ENV above (which is a better solution, imho) and Jenkins will read Dockerfile from main workspace/git directory. Hope that helps.
