I'm trying out all the dagger functions listed in the Go api ref and wondering when I would rather use dagger.Host().EnvVariable("FOO") instead of just loading envs normally with os.Getenv("FOO").

Could someone clarify this?

it'll probably be removed soon. it was added so we could support loading env vars as secrets, but there's a new secrets api now that lets you just do dagger.SetSecret("foo", os.Getenv("BAR")) instead

right, that's what I assumed, thanks 🙌

ohh.. this is so sweet!

sec := client.SetSecret("someToken", os.Getenv("SOME_TOKEN"))
baseImage := client.Container().From(baseImage)
img := baseImage.
    WithSecretVariable("SOME_TOKEN", sec)
...
debug(img.WithExec([]string{"env"})) -> SOME_TOKEN=***

Is this in the latest SDK releases?

#

I'm stuck on a slightly older SDK until Alpine3.17 ships with Python 3.11 or my org updates our base image

I think it was in v0.4.1

That might explain why I've not seen/tried it yet

@rigid turtle and @modern tide are working on a new secrets guide now
