#18544 Docker not recognizing `[docker].env_vars` Issue created by rhuanbarreto Describe the bug I setup pants.toml with: [docker] env_vars = ["GITHUB_SHA=development"] build_args = ["GITHUB_SHA"] [environments-preview.names] docker_linux = "//:docker_linux" local_mac = "//:local_mac" local_linux = "//:local_linux" And BUILD file: local_environment( name="local_mac", compatible_platforms=["macos_arm64"], fallback_environment="local_linux", ) local_environment( name="local_linux", compatible_platforms=["linux_x86_64"], fallback_environment="docker_linux", ) docker_environment( name="docker_linux", platform="linux_x86_64", image="python:3.11.2-slim-bullseye", python_bootstrap_search_path=["/usr/local/bin"], ) I get an error when I run

pants package ::

:

[ERROR] 1 Exception encountered:

Engine traceback:
  in `package` goal

DockerBuildContextError: Undefined value for build arg on the <redacted>:app target: The Docker environment variable 'GITHUB_SHA' is undefined. You may provide a value for this variable either in `[docker].env_vars` or in Pants's own environment.

If you did not intend to inherit the value for this build arg from the environment, provide a default value with the option `[docker].build_args` or in the `extra_build_args` field on the target definition. Alternatively, you may also provide a default value on the `ARG` instruction directly in the `Dockerfile`.
