📝 Walkthrough

Walkthrough

The pull request parameterizes the Kubimo Dockerfile to accept a base image reference as a build argument (KUBIMO_MARIMO_IMAGE) with a default value. This build argument is exposed through the Docker Bake configuration file, allowing the base image to be customized at build time.

Changes

Cohort / File(s)	Summary
Docker Bake Configuration docker-bake.dev.hcl	Adds args block to docker-metadata-kubimo target with new build argument KUBIMO_MARIMO_IMAGE set to ghcr.io/aqora-io/kubimo-marimo:${TAG}, enabling dynamic base image specification.
Kubimo Dockerfile docker/Dockerfile.kubimo	Parameterizes base image via ARG KUBIMO_MARIMO_IMAGE with default ghcr.io/aqora-io/kubimo-marimo:0.1.9; updates both build and final stages to use FROM ${KUBIMO_MARIMO_IMAGE}. Expands build context to include full Rust compilation (sets workspace, copies rust-toolchain, builds release binary) and adds environment PATH updates and workspace file copies to final stage.

Poem

🐰 A parameter hops into the Dockerfile so neat,
The base image now dances to a variable beat!
With Rust compiling, and venv in the brew,
Kubimo's container is fresh and made new! 🐇✨

docker/Dockerfile.kubimo (2)

1-3: LGTM! Correct pattern for parameterizing base images in multi-stage builds.

The ARG declaration before the first FROM correctly makes it available for all FROM instructions. The default value provides a stable fallback for standalone builds.

---

22-22: Consistent use of the parameterized base image.

Both build and final stages now use the same configurable base image, ensuring version consistency across stages.

docker-bake.dev.hcl (1)

7-9: LGTM! Build argument correctly wired to coordinate versions.

The args block properly overrides the Dockerfile default, using ${TAG} to keep the base image version aligned with the output image tag during bake-driven builds.
