Docker Build
Docker build found stage names that are not lowercase
StageNameCasing
Docker build checks found Dockerfile stage aliases that are not lowercase, which violates the build rule for stage naming consistency.
Error AtlasError Documentation and ResolutionObserved message
StageNameCasing
Why it happens
- A Dockerfile stage alias contains uppercase letters.
- Build stages were named inconsistently across a multi-stage Dockerfile.
- A copied example kept stage aliases that do not match the current style rules.
How to fix it
- Rename stage aliases to lowercase values.
- Update all COPY --from references to use the new lowercase stage names.
- Keep future stage aliases consistently lowercase across the Dockerfile.
