05/17/2021, 4:15 PMHi pants experts, I'd like your suggestion on how to store environment variables and their values when building a PEX file. I guess I can do "my_env=somevalue my_pex" when running the pex file, but this doesn't scale in my case where I need to set tons of env variables. I see a relevant open issue https://github.com/pantsbuild/pants/issues/10352, so I assume this is not yet supported? Thanks

05/17/2021, 4:56 PMHi, it sounds like you're trying to "bake" env var values into the pex file so that they are set at its runtime? That issue is about something else - setting env vars to control how arbitrary processes work.

05/17/2021, 4:57 PMSo the goal is to set env vars at build time that get embedded in the pex file and appear in its environment at runtime?

05/17/2021, 5:00 PMI am building a pex that is bundled with apache-airflow and a few relevant dependencies so that I can use pex to run a DAG locally. There are many env variables that are needed for credentials, airflow runtime configs, etc

05/17/2021, 8:01 PMThanks John and this is great to know! It seems the workaround is to manually run a script to set all the env variables before executing the PEX file. I am looking forward to a contribution for this issue.
