I'm following a tutorial about Jenkins pipeline and I can get a "hello world" working under at node 6.10 docker container.
But, when I added a default EmberJS app (using ember init
) to the repo and attempt to build that in the pipeline, it fails when running npm install (because of directory access issues). The Jenkinsfile can be seen here: https://github.com/CloudTrap/pipeline-tutorial/blob/fix-build/Jenkinsfile
The error message printed by the build is (which is installed locally and run using java -jar jenkins.war
on a Macbook, not relevant but included just in case) is:
npm ERR! Linux 4.9.12-moby
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install"

Note: I would like to not run npm install
as root / sudo.
UPDATE: I have been able to make some progress as follows:
I found the command that Jenkins uses to build using the container from the logs:
[Pipeline] withDockerContainer
$ docker run -t -d -u 501:20 -w /long-workspace-directory -v /long-workspace-directory:/long-workspace-directory:rw -v /long-workspace-directory@tmp:/long-workspace-directory@tmp:rw -e
So when the docker image runs, it's work directory is a /long-workspace-directory
(it's really a cryptic looking jenkins workspace path) and the user id is 501 (group id 20), etc. The user doesn't have a name (which is apparently breaking other things not related to this question).
Changed agent to use a Dockefile:
agent { dockerfile { filename 'Dockerfile' args '-v /.cache/ -v /.bower/ -v /.config/configstore/' } }
Specify
args '-v ...'
for creating volumes for the directories npm install / bower needs.
npm ERR! Please try running this command again as root/Administrator.
try this hint. – Ember Freaknpm install
as root; it's considered really poor form; i'd like to avoid that. – les2
