Support podman for the Docker Compose feature

[philiplourandos]

Environment

• OS: Ubuntu 24.10
• Java: OpenJDK Runtime Environment GraalVM CE 23.0.1+11.1 (build 23.0.1+11-jvmci-b01)
• Podman: podman version 5.0.3
• Spring boot: 3.4.0

The problem

I have created a very quick demo project using start.spring.io and seeing the same behaviour I am seeing in my project. Error is as follows:

[INFO] --- spring-boot:3.4.0:run (default-cli) @ demo ---

The docker-compose file looks like:

services:
  postgres:
    image: 'postgres:latest'
    environment:
      - 'POSTGRES_DB=mydatabase'
      - 'POSTGRES_PASSWORD=secret'
      - 'POSTGRES_USER=myuser'
    ports:
      - '5432'

• Running docker-compose up from the CLI starts it up with no problems
• I do have a podman aliasing dependency installed on the system so the normal docker commands work except using podman.
• Using test containers from spring boot works fine.
• Building OCI images works fine.

I'm not keen to switch from podman to docker, tho that is certainly one way to probably resolve this.

Any assistance would be appreciated

[mhalbritter]

Hello,

we're parsing the output of docker and docker compose (or docker-compose). As you have essentially symlinked podman to docker, this is not a supported arrangement. We can look into how much work it'd be to also support podman, but I can't make any promises because I don't know how much the podman output differs from docker.

What works is that you enable the podman socket and then use the original docker binary to use that socket. In effect, this runs your container with podman, but using docker and docker compose as a podman client. I've explicitly tested that scenario while working on the docker compose feature in Boot.

Thanks Moritz. Will give that a try and provide feedback

I seem to be having the same issue. I have enabled podman as a service in systemd:

What is docker version and docker compose version showing?

It should show something like this:

the docker client is from docker, and the server is a podman.

If your client is a podman, too, then there's something wrong on your machine. The client needs to be a docker, not a podman.

[mhalbritter]

Please leave this issue open, as we'd like to add Podman support.
