问题
I am tring to build and publish my job with the help of CloudBees Docker Build and Publish plugin. I added my credentials to Jenkins. When I build the job, it stucks at pushing into Docker by saying authentication error. I checked from cmd that I can login to docker and I could created the image but cannot do it with Jenkins. Do you have any idea about how to solve this problem? Error log is in the following:
[jenkins-docker] $ docker tag c89e01bffe59 reponame/imagename:latest
[jenkins-docker] $ docker inspect c89e01bffe59
[jenkins-docker] $ docker push reponame/imagename:dockerhub
The push refers to repository [docker.io/reponame/imagename]
