#18764 Docker environment variables set in pants.toml appear to not get passed through Issue created by zyd14 First off, thanks for the really cool tool, it's been a trip learning how to use it. Describe the bug I had a number of

docker_image

targets which were working fine for some time. Today I when to run one and encountered this error:

I've encountered this error before when I was first setting up pants in the repo and fixed it by adding the USER, HOME, and PATH variables to

[docker.env_vars]

in my

pants.toml

file. But now those variables are set (and appeared to be working for some time), leaving me with an unclear path to exposing these variables to the pants environment. I've also confirmed that

sw_vers

is in my PATH, and that USER and HOME are actually set.

# pants.toml
[docker]
env_vars = [
  "HOME",
  "USER",
  "PATH",
  "GIT_COMMIT"
]

With

pants package -ldebug <target>

I noticed this message in the logs:

Which seems to indicate to me that no environment variables from my

pants.toml

file are being passed through to the underlying

docker build

call (

__UPSTREAM_IMAGE_IDS

isn't one of my env vars). I also tried clearing out my docker and pants caches to no avail. Any potential workarounds are more than welcome in lieu of a direct fix, this is a bit of a blocker for me. Thanks for all your help and the really awesome tool.
