Re: [packer] Packer can't find user when run from within container

[Rickard von Essen]

Could you provide some more context here? Give us a example packer template (.json) and what do you mean with a container ? a docker container, if so can you specify the command you started it with.

It might just be that env var USER is not set. If I run: docker run -it ubuntu:trusty bash  USER is not set. You could just define it.

Trying to run packer inside of a Container. I keep getting the error:

* user: could not determine current user from environment.

It runs fine from the host that manages the Container but I get the error when running within the Container.

Any ideas? Can I define the user?

Welp, accidentally deleted original post. 

But I figured out the issue. I'm running a Jenkins server in a Docker Container. 

Was getting an issue where packer wouldn't run but setting the user variable while root fixed the issue. 

Not sure why Jenkins is running as root but thats a different issue.

Thanks!

If you start docker there is a option -u <user> to select the user the process in the container will use. If not specified it will check if there is one defined in the image (with USER) if not default to root.
