Run "From .." docker image inside Dockerfile

Question

I'm building a image that builds a Jenkins and I try to use a plugin over the Jenkins when it is running, so, I need get run Jenkins before my plugin execution.

I execute it like docker build -t dockerfile and the error which I am obtaining:

jenkins.JenkinsException: Error in request: [Errno 99]
Cannot assign requested address

I think the problem is when the plugin is executed it guess Jenkins is running and not.

I had the same issue myself when using it under Docker:

File "/src/.tox/py27/local/lib/python2.7/site-packages/jenkins_jobs/builder.py", line 124, in get_plugins_info raise e JenkinsException: Error in request: [Errno 99] Cannot assign requested address

That was caused when it tries to retrieve the list of plugins, I went overriding plugins_info to short circuit the code path:

jjb = JenkinsJobs(args=['test', config_dir, '-o', output_dir])
jjb.builder['plugins_info'] = []  # prevents 99 cannot assign requested address
jjb.execute()

I had the issue with python 2.7.9 on Debian Jessie. If I remember correctly that is no more an issue with a later python version eg 2.7.13 from Debian Stretch.

(the patch on which I encountered the issue): https://gerrit.wikimedia.org/r/#/c/380929/8/tests/test_integration.py

RUN brew install libyaml

brew is a package manager for Mac OS X. Also PyYAML gracefully skip compilation when the lib is not availble. So you probably do not need that one. And I guess it would work without installing build-essential.

RUN pip install jenkins-job-builder==2.0.0.0b2 RUN pip install PyYAML python-jenkins

I am surprised you have install PyYAML and python-jenkins explicitly. Supposedly installing jenkins-job-builder should install all the dependencies (eg PyYAML and python-jenkins).
