bake hcl file - Unsuitable value type on fields `cache-from` and `cache-to`

[ggjulio]

I have the following error on cache-from and cache-to.

Unsuitable value type (Unsuitable value: invalid value $BAKE_CACHE_OPTS)Docker DX (docker-language-server)

To me it's a false positive, the value it is passed as environment variable by a wrapper script.
Not sure if it should be "fixed" though.

@ggjulio Thanks for the report. If you call docker buildx bake --call check TARGET_NAME you'll get the same error, right?

What is BAKE_CACHE_OPTS in your build script (which presumably works when actually performing a build)?

@ggjulio Does this help as a workaround?

cache-to = [
  {
    type = "${BAKE_CACHE_OPTS}",
    ref = "${BAKE_CACHE_REGISTRY}/nxdh-base:${GIT_BRANCH_SANITIZED}"
  }
]

Does this help as a workaround?

Yes, it's more verbose but the workaround works fine, ty! (we have many images with theses two properties)

Great to hear! I think we may have to rethink how this works or offer less validation here...
