dockerfile_inline ignored #1332
Description
Describe the bug
Using the compose file below with podman compose --file docker-compose.yml up results in the Dockerfile in the folder being used for the build instead of dockerfile_inline or an error if not Dockerfile is in the folder (Error: no Containerfile or Dockerfile specified or found in context directory, C:\foo: The system cannot find the file specified.).
docker-compose.yml
services:
caddy:
image: foo/caddy:latest
build:
dockerfile_inline: |
FROM caddy:builder AS builder
RUN \
xcaddy build \
--with github.com/caddyserver/transform-encoder
FROM caddy
COPY --from=builder /usr/bin/caddy /usr/bin/caddy
pull_policy: build
To Reproduce
Steps to reproduce the behavior:
podman compose --file docker-compose.yml up
Expected behavior
foo/caddy:latest is built with the inline dockerfile
Actual behavior
Dockerfile in folder where the command is run is used or an error if no Dockerfile present.

Additional context
I reported this in podman, but they say that the issue is with this project instead. I mentioned this in this related issue, but opened a new one given that one is close.
podman compose has the same result as podman-compose. Using docker compose with podman seems to work.
