Can I expect the syntax

extra_build_args=['FURY_AUTH=%(env.FURY_AUTH)s']

to work in a

BUILD

file, I'm trying to create a Docker image target. I can do

[docker]
build_args = ['FURY_AUTH=%(env.FURY_AUTH)s']

in

pants.toml

but I haven't had any luck figuring out the corresponding syntax in a

BUILD

file.

On new-enough versions (>= 2.16.0dev5), I think you can do something like

extra_build_args=[f"FURY_AUTH='{env('FURY_AUTH')}']

using the new

env()

build-file function. https://github.com/pantsbuild/pants/blob/main/docs/markdown/Using%20Pants/concepts/targets.md#environment-variables That's not too helpful for earlier versions, though

Thanks! That's good to know

Is this example what you are looking for?
