- Failing step: Step [5/5] RUN git submodule update --init --recursive &&     make -C svgo all &&     make -C imageoptim all
  - Exit code: 2

- Exact error messages to preserve:
  - /bin/sh: 1: codesign: not found
  - make: Leaving directory '/work/imageoptim'
  - make: *** [Makefile:15: pngout] Error 127
  - Final docker build failure: ERROR: failed to solve: process ".../bin/sh -c git submodule update --init --recursive &&     make -C svgo all &&     make -C imageoptim all" did not complete successfully: exit code: 2

- What caused it:
  - imageoptim build attempted to build pngout via a Makefile target and tried to codesign the binary:
    - codesign -s "Developer ID" ./pngout --force
  - The container environment does not have codesign installed; codesign not found, causing the make target to fail with exit code 127

- Missing packages/files mentioned:
  - codesign tool (not found in the container)
  - macOS-specific pngout (pngout-20230322-mac.zip) suggests macOS tooling invoked in a Linux-based Docker image

- Version mismatch information:
  - Node/webpack engine mismatch:
    - node v12.22.9 and npm 8.5.1
    - webpack-cli@5.1.4 requires node >= 14.15.0
  - EBADENGINE warnings appear multiple times; not fatal but indicate potential incompatibility

- Context note:
  - Error occurs after substantial apt-get and npm install steps; root failure is codesign missing when the imageoptim Makefile tries to sign a macOS binary

- Key file/paths:
  - /work/imageoptim
  - PNGOut signing: ./pngout
  - Makefile:15
  - Command segment: git submodule update --init --recursive && make -C svgo all && make -C imageoptim all
