How do I specify which Dockerfile is to be used for each app's components?

Hi there,

You should be able to use the dockerfile_path directive in your App Spec definition. The path to the Dockerfile is relative to the root of your repo. If set, it will be used to build this component. Here is an example:

name: sample-dockerfile
services:
- name: web
  git:
    repo_clone_url: https://github.com/digitalocean/sample-dockerfile.git
    branch: main
  dockerfile_path: Dockerfile

There is no need to use docker-compose you would just have to define all of your services in your app spec file as separate components instead.

Here is a reference to the documentation that might be helpful as well:

Let me know how it goes!

Best,

Bobby
