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.

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

✅ Good: all uppercase.

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

✅ Good: all lowercase.

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