App Platform App Spec with Image

Question

I am currently trying to deploy a existing container image to app platform

I created a repository with nothing but the file .do/app.yaml, contents:

name: sample-metabase
services:
- name: metabase-app
  image:
    registry_type: "UNSPECIFIED"
    registry: "hub.docker.com"
    repository: "metabase/metabase"
    tag: "v0.37.2"
  instance_size_slug: "basic-xxs"
  instance_count: 1
  http_port: 3000
  routes:
  - path: /

From my, limited, understanding this should work. However app platform tells me “We’re sorry, but we weren’t able to detect anything that the App Platform can currently run in the repository you selected. Please try a different repository.” - What am I missing?

Currently, only DigitalOcean Container Registries (DOCR) registries are supported as an image source type. If you were to upload your metabase:v0.37.2 to your DOCR registry, you could reference it as follows:

name: sample-metabase
services:
- name: metabase-app
  image:
    registry_type: "DOCR"
    repository: "metabase"
    tag: "v0.37.2"
  instance_size_slug: "basic-xxs"
  instance_count: 1
  http_port: 3000
  routes:
  - path: /

We automatically infer the registry associated with your account and handle credential management.

Public Dockerhub image support is on the roadmap and will be available in the near future. Additionally, I will open up an internal support ticket to better handle the failure messaging in this case to make it more clear.

Error still is not clear, also in your documentation ( https://www.digitalocean.com/docs/app-platform/references/app-specification-reference/ ) you should state that using services.image.registry is unsupported. Just lost two hours debugging it …

  I had this same problem too. It turned out that my issue was that I was running an older version of doctl CLI (1.48.0 instead of 1.56.0). Everything worked after that. Here is what it looks like for Hasura, I’m sure metabase is similar:
  
  name: hasura region: sgp1 services: - name: hasura image: registry_type: DOCKER_HUB registry: docker.io repository: hasura/graphql-engine http_port: 8080

  Actually, I’m sorry — this fixed the CLI bugging out but didn’t actually deploy. I had pull from docker hub and push into my private DO registry as per these instructions: https://www.digitalocean.com/community/questions/how-do-i-uload-my-docker-image-to-digital-ocean
  
  I can probably automate this for now but it would be nice if pulling public images from Docker Hub would just work.
