Summary (under 1500 chars):

- Failing step
  - RUN pip install mkdocs-material==9.5.5 mkdocs-glightbox (Dockerfile: the step that failed)

- Exact error messages and exit code
  - During dependency build:
    - error: command 'gcc' failed: No such file or directory
    - exit code: 1
  - Follow-up failures indicate wheels could not be built:
    - ERROR: Failed building wheel for regex
    - ERROR: Failed building wheel for selectolax
    - x Failed to build installable wheels for some pyproject.toml based projects
  - Final log note for the failing step:
    - Docker step did not complete successfully: exit code: 1

- Failing command/step details
  - [ 3/15] RUN pip install mkdocs-material==9.5.5 mkdocs-glightbox

- Missing packages or files mentioned
  - gcc is missing in the image (No such file or directory)

- Version mismatch / environment notes
  - Base image uses python:3.15.0a7-alpine3.22 (Python 3.15 alpha), which may lack prebuilt wheels and require a C compiler to build packages from source
  - The log shows wheels being built from source (regex, selectolax) due to the alpha Python version, and the build fails because gcc is not installed

- Implication / fix (brief)
  - Install build tools in the image prior to pip installs (e.g., apk add --no-cache build-base) or use a Python base with dev tools and a stable Python version.

Image python:3.11-alpine exists on Docker Hub.

Summary (under 1500 chars):

- Failing command/step:
  - [14/17] RUN mkdocs build -f mkdocs.yml -d /hello-algo/site

- Exit code:
  - 1 (Aborted with 2 configuration errors!)

- Exact error messages (preserved):
  - WARNING -  Config value 'version': Unrecognised configuration name: version
  - ERROR   -  Config value 'theme': The path set in custom_dir ('build/overrides') does not exist.
  - ERROR   -  Config value 'docs_dir': The path 'build/docs' isn't an existing directory.
  - Aborted with 2 configuration errors!

- Missing packages/files mentioned:
  - build/overrides (theme custom_dir path does not exist)
  - build/docs (docs_dir path does not exist)

- Version mismatch / compatibility info:
  - The mkdocs.yml contains a top-level config key 'version' which MkDocs reports as unrecognised with MkDocs version in use (MkDocs 1.5.3 as seen in the log).
  - The errors also indicate misalignment between config expectations (docs_dir pointing to build/docs and theme overrides at build/overrides) and the actual filesystem (docs copied to ./docs earlier). This suggests a config/filesystem mismatch or outdated config for the MkDocs version in the image.
