Hi everyone. I've tried searching this channel to no avail. I have successfully built a Pex file and have it running in a Docker container with

pants run

. Everything works perfectly. I'm able to pass environment variables in with

--docker-run-args="-e MY_VAR=var123"

, and this also works. However, if I do this

--docker-run-args="--env-file .env"

, assuming that the .env file is in the current working directory, I get the following error:

docker: open .env: no such file or directory.

Is loading environment variables from a file supported by Pants in this case? I'm on version 2.16.0rc1.

Hi Gary, My guess would be that your

.env

file is not present in the sandbox, meaning there is nothing depending on it to make Pants include it.

oh, hmm.. wait,

run

is interactive, so the sandbox argument may be moot here…

To answer this, yes, if you use

scie-pants

(the new Pants launcher binary) you can have a

.env

file to load env vars from in the root of the repo. Otherwise you can have a

.pants.bootstrap

script with

export VAR=value

in it which will work in either launcher version (script or binary)

That's brilliant, thanks, I'll move the

.env

file.
