Recommended action: Check the build context path (last argument of docker build) and every ignore file (root .dockerignore and any <Dockerfile>.dockerignore next to the Dockerfile, which takes precedence); un-ignore the file or adjust the COPY path relative to the context root.
Option: Make the file part of the build context [evidence: official_recommended_action]
Applies when: COPY source exists on disk but build says not found
Steps:
1. Confirm the context directory passed to docker build (e.g. `.` vs a subdirectory)
2. Search .dockerignore and <Dockerfile>.dockerignore for patterns matching the path; add a `!path` exception or remove the pattern
3. Make COPY paths relative to the context root, not to the Dockerfile location
Expected: COPY step finds the file
Evidence basis (self-declared by the contributing chat client): untested.
