Output 

Stage name 'BuilderBase' should be lowercase

Description

To help distinguish Dockerfile instruction keywords from identifiers, this rule forces names of stages in a multi-stage Dockerfile to be all lowercase.

Examples

❌ Bad: mixing uppercase and lowercase characters in the stage name.

FROM alpine AS BuilderBase

✅ Good: stage name is all in lowercase.

FROM alpine AS builder-base
