Concerns: FROM ruby:3.4.7 may not be a valid public image tag; verify that ruby:3.4.7 exists on Docker Hub or switch to a supported tag like ruby:3.2.x or ruby:3.3.x, The build relies on Thor being available to run docs:download and assets:compile; ensure Thor is listed in the Gemfile and installed during bundling, Build-time asset/docs download (thor docs:download --all) can make builds slow or flaky; consider caching assets or moving to a multi-stage build if appropriate

Concerns: FROM ruby:3.4.8 may be an invalid/non-existent tag in the official Ruby images. If the base image tag does not exist, the build will fail during docker build., Assuming Gemfile.lock exists in the build context; if not, the COPY of Gemfile.lock could fail the build., The use of 'bundle config path.system true' and relying on system-installed gems may lead to non-reproducible builds; consider using a more deterministic Bundler configuration (e.g., vendor/bundle) and/or 'bundle exec rackup' at runtime.

- /bin/sh: 1: thor: not found
- exit code: 127
- Failing command / step
- [9/9] RUN thor docs:download --all && thor assets:compile
- Missing packages or files mentioned
- Thor CLI (thor) not found: the build attempts to run the thor commands but the thor binary is not installed in the image at that stage.
- Version mismatch information
- Base image used: FROM docker.io/library/ruby:3.3-slim
- During the Ruby build step, logs show:
- Configuration summary for ruby version 3.4.8
- BASERUBY = /usr/local/bin/ruby --disable=gems
- BASERUBY -v: ruby 3.3.10 (2025-10-23 revision 343ea05002) [x86_64-linux]
- This indicates a Ruby 3.4.8 build path with a BASERUBY version reported as Ruby 3.3.10, i.e., a mismatch between the built Ruby version and the BASERUBY/runtime version reported during configuration.
Notes:
- The error arises at the final asset/docs step, where Thor is expected to be available to run docs:download and assets:compile. No thor binary/installation is shown in prior steps, so the step fails due to missing Thor.FROM ruby:3.3-slim

Summary:
- VerifyBuild status: build_failed
- Key concerns:
- Build relies on network to download docs/compile assets; may fail in restricted environments
- Smoke tests assume Rack on port 9292 and root path; routing/port differences may require test adjustments
- If Gemfile or Gemfile.lock are missing from the build context, the build will fail
- Failing step: [7/9] RUN bundle config set --local path /usr/local/bundle && bundle install
- Exit code: 5
- Core failure sequence:
- Bundler 4.0.8 is running, but your lockfile was generated with 2.4.6. Installing Bundler 2.4.6 and restarting using that version
- Gem installation proceeds but Eventually: Gem::Ext::BuildError: ERROR: Failed to build gem native extension
- Working directory: /usr/local/bundle/ruby/3.3.0/gems/psych-5.3.1/ext/psych
- Command: /usr/local/bin/ruby extconf.rb
- Missing dependencies detected during extconf.rb:
- checking for pkg-config for yaml-0.1... not found
- checking for yaml.h... no
- yaml.h not found
- extconf.rb failed; Could not create Makefile due to missing libraries/headers; see mkmf.log
- mkmf.log path: /usr/local/bundle/ruby/3.3.0/extensions/x86_64-linux/3.3.0/psych-5.3.1/mkmf.log
- An error occurred while installing psych (5.3.1); Bundler cannot continue
- Gemfile dependency chain (selected):
- dartsass-sprockets (3.2.1) -> railties (7.2.3) -> irb (1.16.0) -> rdoc (7.1.0) -> psych
- Missing files/packages:
- yaml.h not found
- pkg-config for yaml-0.1 not found
- Implication: YAML development headers (libyaml-dev or equivalent) are missing
- Version mismatch details:
- Observed: Bundler 4.0.8 running
- Lockfile: generated with 2.4.6
- Action taken: Bundler attempts to fetch/install Bundler 2.4.6
- Conclusion: Bundler version mismatch between running Bundler (4.0.8) and lockfile (2.4.6) caused a forced downgrade/restart during bundle install
- File paths to checkpoints:
- mkmf.log: /usr/local/bundle/ruby/3.3.0/extensions/x86_64-linux/3.3.0/psych-5.3.1/mkmf.log
- psych extension dir: /usr/local/bundle/ruby/3.3.0/gems/psych-5.3.1/ext/psychFROM ruby:3.3-slim

Concerns: Gemfile locking compatibility: the script attempts to align Ruby versions in Gemfile.lock by replacing specific strings, which may be brittle if the lockfile format differs or versions change., Smoke tests are not validating the actual web service response or startup health; consider adding a lightweight check that the Rack server would be reachable after startup., The image relies on building system dependencies (nodejs, libxml, etc.). If those are not strictly required by the app, they could be trimmed to reduce image size. Smoke [PASS]: test -f /devdocs/Gemfile && test -f /devdocs/Gemfile.lock && test -f /devdocs/Rakefile Smoke [PASS]: ruby -v Smoke [FAIL]: bundle check --path /usr/local/bundle Output: [DEPRECATED] The `--path` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local path '/usr/local/bundle'`, and stop using this flag Your Ruby version is 3.3.10, but your Gemfile specified 3.4.8

Recommended next steps: - Ensure Gemfile.lock exists in the build context or modify Dockerfile to COPY only Gemfile and run bundler without Gemfile.lock. - Remove or adjust the .dockerignore rule that excludes Gemfile.lock (referenced at .dockerignore line 26) to allow copying. - Confirm the base image tag is valid; if ruby:3.4-slim is unavailable, switch to a supported tag like ruby:3.3-slim or 3.2-slim.

Concerns: Base image tag 'ruby:3.4-slim' may not exist in the public Docker Hub tags (as of prior knowledge) and could cause build failure. Consider using a known tag like 'ruby:3.2-slim' or a specific release version that exists., Bundle configuration 'bundle config set path.system true' is unusual; ensure this is intended and compatible with the Bundler version in use. It could affect where gems are installed and may cause inconsistencies across environments., Building docs/assets during image build ('thor docs:download --all' and 'thor assets:compile') increases build time and image size; consider moving heavy build steps to runtime or ensuring they are strictly necessary for the deployed image.FROM ruby:3.4.7-slim

Concerns: FROM image tag ruby:3.4.8-slim may not exist or be valid; Ruby 3.4.x is not a released major line in common Docker Ruby images. Consider using a supported tag such as ruby:3.1-slim or ruby:3.2-slim., Relying on a specific Ruby version tag that may not be available could cause build failures. Ensure the base image tag exists in the registry., Optional: The Dockerfile uses a fairly heavy set of system dependencies; ensure they are necessary for the app and consider pinning versions to improve reproducibility.
