Hi all -
I have a docker host. Jenkins ssh's (as the user jenkins) to this host via
pipeline steps and builds apps inside the specified docker image. This all
pretty much flows as planned. However... when the pipeline executes a
"docker.insdie" or via pipeline -> agent -> docker, the docker image is
always launched as the jenkins user. Even if I specify "-u root" in the
option, it's still has the "-u 501" which is the jenkins user.
How can I get around this? My build steps requires me to be able to
create a /go/src/<etc> directory and the jenkins user doesn't have
permissions to do this (it doesn't even exist on the docker image).
Here's the output... you can see that the docker run actually includes the
-u 501 and the -u root.
