extra_hosts doesnt add the entry to podman build command #1366
Description
Describe the bug
Adding extra_hosts entry in the compose file doesnt add add-hosts argument to the podman build command. This is needed to add DNS entry for image build.
To Reproduce
Steps to reproduce the behavior:
docker-compose.yml
version: "3.9"
services:
curl-test:
build:
context: .
extra_hosts:
- "example.internal:103.158.42.45"
container_name: curl-extra-hosts-test
extra_hosts:
- "example.internal:103.158.42.45"
command: >
sh -c "
echo 'Curling example.internal...' &&
curl -I http://example.internal &&
sleep 3600
"Dockerfile
FROM alpine:latest
RUN apk add --no-cache curl
RUN curl -I http://example.internal
CMD ["sh"]Expected behavior
Both curl in image building step and the shell command inside container should succeed
Actual behavior
Fails to resolve the host
Output
