Concerns: Invalid COPY usage: 'COPY local_time.gemspec ./ 2>/dev/null || true' is not valid Dockerfile syntax; COPY cannot have shell redirections or '|| true'. This will fail the build or behave unexpectedly., Using '|| true' on yarn install/build hides real build failures; the image could be built even if asset compilation fails., The image's CMD is just a shell (bash) and there is no entrypoint to run the web service; for a web service you typically start a server (e.g., bundle exec rails server, puma, etc.). Consider adding a proper startup command or a dedicated ENTRYPOINT/EXPOSE.

Concerns: Invalid COPY instruction: 'COPY local_time.gemspec ./ 2>/dev/null || true' cannot include shell redirection or a shell conditional as part of a COPY directive; this will cause a Docker build to fail., Potentially the CMD remains a debugging shell ('bash'), which means the container won't auto-start a web service.

Summary of Docker build error
- Exact error message and exit code
- ERROR: failed to build: failed to solve: process "/bin/sh -c gem install bundler -v 2.4.22 && bundle config --global build.nokogiri --use-system-libraries && bundle install --jobs 4 --without production" did not complete successfully: exit code: 7
- The subsequent gem/bundle error excerpt:
- Your bundle is locked to rubocop-37signals (1.1.0) from rubygems repository https://rubygems.org/ or installed locally, but that version can no longer be found in that source. That means the author of rubocop-37signals (1.1.0) has removed it. You'll need to update your bundle to a version other than rubocop-37signals (1.1.0) that hasn't been removed in order to install.
- Failing command/step
- Dockerfile step: [ 7/11] RUN gem install bundler -v 2.4.22 && bundle config --global build.nokogiri --use-system-libraries && bundle install --jobs 4 --without production
- Missing packages or files mentioned
- Missing gem/version: rubocop-37signals (1.1.0) has been removed from the Rubygems source; the bundle cannot be resolved to a version available in the source.
- Version mismatch information
- Bundler version installed in this step: bundler 2.4.22
- Gem causing the failure: rubocop-37signals (1.1.0) is locked in the bundle but no longer available on rubygems; this creates a version/source mismatch where the locked version cannot be resolved.
- Suggested fixes
- Update the Gemfile.lock to use a rubocop-37signals version that exists or remove/upgrade that gem, then run bundle update.
- Alternatively, regenerate the bundle by allowing a newer Rubocop entry (e.g., run bundle update rubocop-37signals or bundle update) and then rebuild the image.
- Ensure Gemfile sources can provide the required gem version, or replace the gem with a supported version.source "https://rubygems.org"

Concerns: No non-root user defined; container runs as root by default. Consider adding a non-root user and a simple healthcheck for production deployments., Default CMD runs the test suite (rake test). In runtime, you may want a web server start command instead or separate test vs start behavior. Smoke [PASS]: ruby -v; bundle -v Smoke [PASS]: node -v; yarn -v Smoke [PASS]: bundle exec rake -T
