Docker Images Name Error and Push to DockerHub Fail
Hi Luis,
I got an error message pushing to Dockerhub in Lab 7, chapter 9, page 11 of the lab (when pushing to registry is added) as follows: (see error at end of message).
this was the message from the build before, which seemed to work:
9 exporting to image
9 exporting layers
9 exporting layers 0.5s done
9 writing image sha256:97464fd7b8adadb872e11517b68530760e5cfc0df46fe27f374a1d1028bc39ea done
#9 naming to docker.io/xxxx/worker:v11 done
9 DONE 0.5s****
THIS WAS THE ERROR AT END OF BUILD AND IMAGES NOT PUSHED TO DOCKERHUB: From the messages i conclude some image validation triggers and maybe prevents the push to the registry. But thats the code from the lab and i doubt there is a mistake (as the image name is being exactly as the code suggests)?
docker.withRegistry('https://index.docker.io/v1/',
'dockerlogin') { def workerImage =
docker.build("xxxxxxxx/worker:v${env.BUILD_ID}", './worker')
workerImage.push('{env.BRANCH_NAME}')
workerImage.push('latest')
}
}
}

I am sorry if it looks a it messy. My setup is actually the exact course setup, except the Jenkins Version, which had to be increased due to some error. Thats the only thing I "changed" during lab 1 to 7.

I will try to make it next week on Wednesday to the office hours and in the meantime try to start again with a clean set up. If you have any ideas where to troubleshoot, I am more than happy.

Hi @basticloud,
I'll see if I can reproduce the issue and I'll let you know.
I see you on Wednesday!

Hi @basticloud ,
I found a similar error here:
https://stackoverflow.com/questions/71610266/name-must-follow-the-pattern-on-jenkins-build
So, it says it's related to use double quotes when declaring a variable as 'image'. Until this moment, I don't see we are doing that, but I'm still checking.
Regards,
Luis.0
