Hi all. I am getting an error testing out docker functionality.
Copy code
#3 [internal] load metadata for <http://docker.io/library/python:3.8|docker.io/library/python:3.8>

failed to solve with frontend dockerfile.v0: failed to create LLB definition: rpc error: code = Unknown desc = error getting credentials - err: exit status 1, out: ``
I was following the errors it showed for env variables and tools. Currently have this in my pants.toml
Copy code
```
[docker]
env_vars = [
  "HOME",
  "USER",
]

tools = ["sh", "sw_vers"]
```
Not really sure where to go next. For reference, the image I am building is this:
Copy code
FROM python:3.8

RUN python3 -c "print('Hello world from docker')"

I suspect that your docker credentials plugin is not available on the hermetic PATH used by pants. Is
docker-credential-desktop
an executable? If so, and if that’s the credentials plugin, it’s path needs to be on the PATH availabe to pants processes.

it is an executable. I added it as well to
tools
. Still getting the same error.
Hmm. by adding
PATH
to
env_vars
I was able to build the image. Not sure if its a good idea…
Its seems to be working. is having
PATH
in env vars a good idea?

For future reference: I’m running macOS and had to add`osascript` in addition to
sh
and
sw_vers
to run docker using
docker-credentials-desktop
as credentials manager.
