Workarounds

  1. 95% success Add .dockerignore with node_modules, .git, and data dirs 
    echo 'node_modules\n.git\n*.log' > .dockerignore

Dead Ends

Common approaches that don't work:

  1. Increase Docker daemon memory 65% fail

    Doesn't fix the root cause, still slow

  2. Move Dockerfile to empty directory 70% fail

    Breaks COPY commands, loses project context
