Question

Deploy to App Platform from Docker Hub

Hi all, I’m setting up a DO button on a GitHub repository, with the following app spec, but I am getting errors saying the image doesn’t exist or is private. How do folks specify in an app spec that an image is on DockerHub?

spec:
  name: docker-stellar-core-horizon
  services:
  - image:
      registry_type: DOCKER_HUB
      registry: hub.docker.com
      repository: stellar/quickstart
      tag: latest
    name: docker-stellar-core-horizon
    run_command: /start --standalone

I’m trying to run it with: https://cloud.digitalocean.com/apps/new?repo=https%3A%2F%2Fgithub.com%2Fstellar%2Fdocker-stellar-core-horizon%2Ftree%2Fissue398

The button is here: https://github.com/stellar/quickstart/blob/issue398/.do/deploy.template.yaml

I can’t use a build from dockerfile because the image is rather complex and multiple images get built and combined, hence why I’m trying to get it to pull from Docker Hub.

The image is not private, it is publicly accessible: https://hub.docker.com/r/stellar/quickstart/tags.

Hey!

A quick update here in case that anyone comes across this in the future.

This is now supported on the App Platform:

https://docs.digitalocean.com/products/app-platform/how-to/deploy-from-container-images/#deploy-container-using-the-apps-spec

You can pass your auth details using the registry_credentials arg:

name: front-end
services:
- name: web
  image:
    registry_type: DOCKER_HUB
    registry: example-registry
    repository: example-repo
    registry_credentials: "your_username:2YotnFZFEjr1zCsicMWpAA"
    digest: sha256:1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef

Hope that this helps!

Hi @leigh! Use the following config:

  - image:
      registry_type: DOCKER_HUB
      registry: stellar
      repository: quickstart
      tag: latest

Let me know if it works!
