Using both Docker and Podman with the same VScode devcontainer

Question

I am using a devcontainer for a school project and it works pretty well. I use Podman myself, but my classmate uses Docker. I want us both to be able to use the same container. How would you go about this?

My Devcontainer.json file. Docker works when the code under "Podman" is commented out.:

{
    "name": "poetry3-poetry-pyenv",
    "build": {
        "dockerfile": "Dockerfile"
    },

    //  Features to add to the Dev Container. More info: https://containers.dev/implementors/features.
    // "features": {},

    //  Use 'forwardPorts' to make a list of ports inside the container available locally.
    "forwardPorts": [8080],

    //  Use 'postCreateCommand' to run commands after the container is created.
    "postCreateCommand": "bash ./.devcontainer/post-install.sh",

    //  Configure tool-specific properties.
    "customizations": {
        "vscode": {
            "extensions":[
            "ms-python.python",
            "njpwerner.autodocstring",
            "tamasfe.even-better-toml",
            "ms-azuretools.vscode-docker",
            "bradlc.vscode-tailwindcss"]

        }
    },
    "mounts": [
        // Re-use local Git configuration
        "source=${localEnv:HOME}/.gitconfig,target=/home/vscode/.gitconfig,type=bind,consistency=cached"
    ],

    "remoteUser": "root",
    "containerUser": "node",
    
    //Podman. Comment out when using Docker
    "workspaceMount": "source=${localWorkspaceFolder},target=/workspace,type=bind,Z",
    "workspaceFolder": "/workspace",

    "runArgs": ["--userns=keep-id"]
}
