Using Containerfile inside podman-compose.yml with podman-compose not working

Question

I am using podman-compose with container-compose.yml file to build my containers which contains application and database container.

This is my container-compose.yml file looks like:

version: "3"
services:
  app:
    build: .
    ports:
      - "5001:5001"
    depends_on:
      - db
    environment:
      - DATABASE_URL=postgres://postgres:1234@db:5432/ApplicationYT
  db:
    image: postgres
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=1234
      - POSTGRES_DB=ApplicationYT
    volumes:
      - db-data:/var/lib/postgresql/data
volumes:
  db-data:

And I have Containerfile in the same path of container-compose.yml file. But when I am trying to use podman-compose to build it, I am getting error OSError: Dockerfile not found in /home/ubuntu/Project/learn_fastapi/Containerfile

This is the full error traceback:

    raise OSError("Dockerfile not found in " + ctx)
OSError: Dockerfile not found in /home/ubuntu/Project/learn_fastapi/Containerfile

It looks like I may have missed something but I have tried to find the resources on how to use Containerfile instead of Dockerfile but I could not find it. And I can use Dockerfile but I don't want to, I just want to continue to podman specific naming conventions.

This are the details about the podman and podman-compose:

podman-compose version 1.1.0
podman version 4.9.3

If anyone can direct in correct direction, I will be very glad. Thank you.

It looks like you hit this bug:

1.1.0 (and perhaps above) broke the use of Containerfiles #977

You can rename (or symlink) your Containerfile to Dockerfile, or add a dockerfile: Containerfile attribute to your build directive:

services:
  app:
    build:
      context: .
      dockerfile: Containerfile
