Ch 6 Lab 4 pull access denied for jenkins-blueocean repository does not exist or may require docker

zacts

Hello,

I'm working through lab4 of LFS261. I'm trying to run docker compose up -d but I'm getting the following warning: ! jenkins Warning pull access denied for jenkins-blueocean, repository does not exist or may require 'docker... 1.1s . I'm also getting this: failed to solve: process "/bin/sh -c jenkins-plugin-cli --plugins blueocean" did not complete successfully: exit code: 1
I'm also getting this warning: WARN[0000] /home/zak/git/devops-repo/setup/docker-compose.yaml: the attributeversionis obsolete, it will be ignored, please remove it to avoid potential confusion

How can I resolve this issue so I can setup the lab?

Thanks.

Hi @zacts,

1.- I was unable to reproduce the error. I just got the same warning message, but it continued to the end, then I was able to run and access it.

2.- What OS and version are you using? Are you running a VM, a cloud system?

3.- What git version are you using?

Regards,
Luis.

Hello,

I'm still getting an error to where I can't access a running Jenkins instance: failed to solve: process "/bin/sh -c jenkins-plugin-cli --plugins blueocean" did not complete successfully: exit code: 1. A running Jenkins instance does not show up when I run docker ps or docker ps -a.

I did look into this a bit on my own, and if I edit the Dockerfile and yaml file to not rely on blueocean and to use the latest jenkins:slim it seem to work for me. I do want to stick as close as possible to the actual course versions for everything though.

Hi @zacts,

I didn't experience the error you got. But if you can run any jenkins container without the 'blueocean' plugin, it will be okey, as you can install it later:

https://www.jenkins.io/doc/book/blueocean/getting-started/

So, at least for this lab you are good to go with the workaround you found.

Regards,
Luis.
