  • add getContainerImage helper, preferring microSandboxConfig.image over customContainerConfig.image
  • resolve container image via getContainerImage in build/deploy/local and acceleration-wait logs
  • include microSandboxConfig when updating function config
  • add image to IMicroSandboxConfig interface and schema; relax schema requirement to either config

Summary by CodeRabbit

  • New Features
    • Added support for specifying a container image for micro-sandbox runtimes.
    • Micro-sandbox images now take precedence over custom-container images.
    • Updated validation to accept either micro-sandbox or custom-container configuration.
    • Preserved micro-sandbox settings during code-only function updates.
  • Bug Fixes
    • Improved handling and trimming of configured container image values.
  • Chores
    • Updated the component version to 0.1.25.

- add getContainerImage helper, preferring microSandboxConfig.image over customContainerConfig.image
- resolve container image via getContainerImage in build/deploy/local and acceleration-wait logs
- include microSandboxConfig when updating function config
- add image to IMicroSandboxConfig interface and schema; relax schema requirement to either config
FC resource is automocked in these test files, so the newly added
getContainerImage static always returns undefined, making _pushImage
and getRuntimeBuildImage throw 'CustomContainerRuntime must have a valid
image URL'. Mock getContainerImage explicitly per test to mirror the
image the local config would resolve to.

📝 Walkthrough

Walkthrough

Adds micro-sandbox container image support with precedence over custom-container images. Centralizes image resolution across build, deploy, local execution, and FC status reporting. Updates validation, tests, and the published version.

Changes

Container image support

Layer / File(s) Summary
Image contract and resolution
src/interface/function.ts, src/schema.json, src/resources/fc/impl/utils.ts, src/base.ts
Adds the optional micro-sandbox image, updates runtime validation, trims both image values, and resolves images with micro-sandbox precedence.
Runtime integration
src/resources/fc/index.ts, src/subCommands/build/impl/baseBuilder.ts, src/subCommands/deploy/impl/function.ts, src/subCommands/local/impl/baseLocal.ts
Uses FC.getContainerImage for image selection, status messages, build, deployment, and local execution. Code-only updates retain microSandboxConfig.
Validation and release
__tests__/ut/resources/fc/impl/utils_test.ts, __tests__/ut/commands/build/impl/baseBuilder_test.ts, __tests__/ut/commands/deploy/impl/function_test.ts, publish.yaml
Tests precedence, fallback, missing images, and image operations. Increments the component version to 0.1.25.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 37181

Local execution for the micro-sandbox runtime can bypass the configured image and run with an unintended container image. The PR is not merge-ready until the runtime predicate is updated and a regression test passes.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Include micro-sandbox in the local container-image branch.

The instance method at Line 136 returns true only for custom-container. It excludes micro-sandbox, although FC.isCustomContainerRuntime supports both runtimes. Therefore local micro-sandbox execution skips FC.getContainerImage and ignores microSandboxConfig.image.

Reuse FC.isCustomContainerRuntime or update the instance predicate. Add a regression test for getRuntimeRunImage() with the micro-sandbox runtime.
