Do you have any special needs for your mount? If not, it'd be easier to simply do:

volumes:
  app:

volumes:
  app:

I usually throw in a pair of curly braces just in case, as in the past at least this would cause issues sometimes:

volumes:
  app: {}

volumes:
  app: {}

It's the same thing since YAML is basically JSON.

I did change volumes and removed them completely and it did complete the process but caddy didn't work The local host kept saying "connection reset"

Are you trying to mount your project's folder to /var/www/html? If so, you can use a simple bind mount:

services:
  caddy:
      image: caddy
      volumes:
        - ./:/var/www/html
      networks:
        - phpapp
      ports:
        - 8080:8080

services:
  caddy:
      image: caddy
      volumes:
        - ./:/var/www/html
      networks:
        - phpapp
      ports:
        - 8080:8080

You can also omit the image tag if you are using latest since that is the default. Although you shouldn't, always pick a specific version and stick to it until you need to update.

Yeah that was the change that worked Just php isn't loading on caddy Might try apache next
