[BUG] Inconsistent validation of host_ip field between short and long syntax of services.*.ports entries. #12815
Description
Description
When specifying an invalid IP address in the host_ip field of a services.*.ports entry, using the short form syntax causes docker compose to output an error, while in the long form syntax the invalid input is accepted.
Steps To Reproduce
Create file short.yaml:
name: host_ip_bug
services:
test:
image: alpine
ports:
- "notavalidip:1234:1234"Create file long.yaml:
name: host_ip_bug
services:
test:
image: alpine
ports:
- host_ip: "notavalidip"
target: 1234
published: "1234"Test config of short syntax:
docker compose -f short.yaml configOutput:
invalid IP address: notavalidip
Test config of long syntax:
docker compose -f long.yaml configOutput:
name: host_ip_bug
services:
test:
image: alpine
networks:
default: null
ports:
- mode: ingress
host_ip: notavalidip
target: 1234
published: "1234"
