'extra_hosts' not working anymore in 'docker stack deploy' #4859
Description
Description
So far, it was possible to pass docker compose config output to docker stack deploy without problems.
Today I upgraded to docker 25.0.2, and discovered loss of the extra_hosts mapping. The tag is completely ignored with the command, and nothing is written to /etc/hosts anymore!
This might be related to:
compose-spec/compose-go#499
compose-spec/compose-spec#156
docker/buildx#2201
Reproduce
cat docker-compose.yml
version: '3.8'
services:
app:
image: httpd:2.4
extra_hosts:
- "host.docker.internal:host-gateway"
Run:
docker compose config | (sed '/^name:/d') | docker stack deploy -c - httpd
Expected behavior
/etc/hosts should show the entry from extra_hosts.
