reactjs - Could not get uid/gid when building Node/Docker

Question

My Dockerfile is using alpine and globally installing react-scripts. When it tries to install it, it fails with "could not get uid/gid" error. I added the "---unsafe-perm" option to the npm install -g command. The docker container is successfully created, but the permissions in the container are messaged up for the installed files. I see the username and group set to 1000 for all of them. I tried adding the following command to the Dockerfile right before the install step but that didn't help.

RUN npm -g config set user root

Build error

Error: could not get uid/gid

UPD Fixed in nodejs@12.4.0?

Check if this is linked to nodejs/docker-node issue 813:

Root cause seems to be: Thread stack size

The default stack size for new threads on glibc is determined based on the resource limit governing the main thread’s stack (RLIMIT_STACK).
It generally ends up being 2-10 MB.

There three possible solutions:

• Talk to Alpine teams to fix it. There were some discussions already
• Fix it in the node docker alpine image as follows
• Set default npm_config_unsafe_perm=true in the docker image as a workaround until it's fixed.

You already tried the third option, but consider also:

Alternatively, you should switch to the slim (Debian) variant until this get's fixe upstream by the Alpine team.
