extension key `template_driver` does not start with "x-"

[decentral1se]

Cool project, thanks for the work! I'm exploring converting our large collection of compose configs into quadlet files to support podman users. I ran into this error straight away.

➜ ~ podlet compose compose.yml
Error:
   0: error converting compose file
   1: error reading compose file
   2: File `/home/d1/.abra/recipes/custom-html/compose.yml` is not a valid compose file
   3: extension key `template_driver` does not start with "x-"

This compose file: https://git.coopcloud.tech/coop-cloud/custom-html/src/branch/main/compose.yml

If I add the x-... it then complains about name and eventually that configs are not supported?

A copy of your config example as reference:

configs:
  nginx_default_conf:
    name: ${STACK_NAME}_nginx_default_conf_${NGINX_DEFAULT_CONF_VERSION}
    file: default.conf.tmpl
    template_driver: golang

Details:

• configs compose-spec
• template_driver is not part of the compose-spec, but can be used as --template-driver option in Docker
• Podman --config for containers does not exist and therefore no templating is available. I will raise an issue in the Podman repository, so lets see what options we have here

Thanks @TheRealBecks 💟

I would be happy to work towards compatibility in our compose configurations or with some sort of translation layer which eventually supports podlet / the actual compose spec so that we can make our growing collection of compose configurations available for podman users.

We are still focusing on using docker swarm and it's implementation does not fully implement the compose spec. I guess you are aware. I will try to follow along in the discussion but please feel free to ping me if there are specific actions I can take. It would be wonderful to make this work eventually.
