uv_os_get_passwd returned ENOENT in docker

[alexesDev]

I build my application in docker, pass current uid via -u and get an error becouse /etc/passwd don't have any info about uid. This error can be repeated like this.

docker run --rm -it -u 200 \ # any uid
  node:10.13-alpine \
  sh -c 'echo "require(\"os\").userInfo()" | node'

SystemError [ERR_SYSTEM_ERROR]: A system error occurred:
uv_os_get_passwd returned ENOENT (no such file or directory

I can mount /etc/passwd from host, but this is bad

docker run --rm -it -u 200 \
  -v /etc/passwd:/etc/passwd \
  node:10.13-alpine \
  sh -c 'echo "require(\"os\").userInfo()" | node'

If use process.geteuid() instead of os.userInfo().username, then there will be no problem.

Line 43 in d7c66ca

const username = os.userInfo().username;

@alexesDev how did you solve this issue?

I got the same issue as well. Though only when running the container in github actions with a volume.

Had the same thing with openshift. The problem was that my user present in /etc/passwd. This can be checked easily with whoami, because it failes in this case. When I add the current user like this, it works:

echo "${USER_NAME:-default}:x:$(id -u):0:${USER_NAME:-default} user:${HOME}:/sbin/nologin" >> /etc/passwd

In my case this is a openshift topic that drives me nuts on a regular basis. I had to build a custom node image that adds RUN chmod g=u /etc/passwd to be able to do this.

Hope it helps someone.
