Output#
'as' and 'FROM' keywords' casing do not match
Description#
While Dockerfile keywords can be either uppercase or lowercase, mixing case
styles is not recommended for readability. This rule reports violations where
mixed case style occurs for a FROM
instruction with an AS
keyword declaring
a stage name.
Examples#
❌ Bad: FROM
is uppercase, AS
is lowercase.
FROM debian:latest as builder
✅ Good: FROM
and AS
are both uppercase
FROM debian:latest AS deb-builder
✅ Good: FROM
and AS
are both lowercase.
from debian:latest as deb-builder
