How to migrate from Python buildpack to Dockerfile without creating a new service?

When I started using App Platform I just connected my Python repo, App Platform auto-recognized what I was using and defaulted me to the python buildpack.

I want to switch over to using my own dockerfile instead of the buildpack, can I do that without creating an entirely new App?

You can switch over to using a dockerfile by updating your app spec to include a dockerfile_path pointing to it.

Your new app spec might look something like this:

name: sample-golang
- name: web
    repo: digitalocean/sample-golang
    branch: master
  dockerfile_path: Dockerfile

Then update using doctl with this:

doctl app update $APP_ID --spec .do/app.yaml
