  • 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 container images for micro-sandbox runtimes.
    • Micro-sandbox images take precedence over custom-container images.
    • Validation now accepts either micro-sandbox or custom-container configuration.
    • Micro-sandbox settings are preserved during code-only function updates.
  • Bug Fixes
    • Improved trimming and handling of configured container image values across build, deployment, and local workflows.
  • 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, __tests__/ut/local/impl/baseLocal_test.ts, publish.yaml, CLAUDE.md
Tests image precedence, fallback, missing images, and micro-sandbox runtime handling. Increments the component version to 0.1.25. Reformats the frozen scope table.

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

Merge Risk: 🔵 Low · up to 3b035

The change adds micro-sandbox image selection across execution paths, but local execution may still proceed with no container image for invalid or incomplete configuration. The PR is mergeable with explicit owner awareness and follow-up to ensure this case is rejected or handled safely.

Comment thread src/subCommands/local/impl/baseLocal.ts
BaseLocal.isCustomContainerRuntime only matched 'custom-container', so
getRuntimeRunImage skipped FC.getContainerImage for the micro-sandbox
runtime and ignored microSandboxConfig.image. Align the predicate with
FC.isCustomContainerRuntime so both container runtimes resolve the image,
and add a regression test for getRuntimeRunImage with micro-sandbox.

218-220: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Reject an empty resolved image before constructing the Docker command.

If neither microSandboxConfig.image nor customContainerConfig.image is set, FC.getContainerImage returns undefined. BaseLocal.getRuntimeRunImage() inserts that value into the Docker command, so local start or invoke can fail with an invalid image argument. Add the empty-image check used by BaseBuilder.getRuntimeBuildImage().
