Output

Command 'EntryPoint' should be consistently cased

Description

Instruction keywords should use consistent casing (all lowercase or all uppercase). Using a case that mixes uppercase and lowercase, such as PascalCase or snakeCase, letters result in poor readability.

Examples

❌ Bad: don't mix uppercase and lowercase.

dockerfile

From alpine
Run echo hello > /greeting.txt
EntRYpOiNT ["cat", "/greeting.txt"]

✅ Good: all uppercase.

dockerfile

FROM alpine
RUN echo hello > /greeting.txt
ENTRYPOINT ["cat", "/greeting.txt"]

✅ Good: all lowercase.

dockerfile

from alpine
run echo hello > /greeting.txt
entrypoint ["cat", "/greeting.txt"]
