I don’t want to hijack this thread if my error is unrelated, but when I try to deploy anything that’s large it takes a long time to push and then I get the following error:

```auto

```

I tried `fly deploy --remote-only` but that shows me:

@rob-gordon Do you still get the `No such image` error? The error you saw when trying to do `--remote-only` is a capacity problem that we can address, but the image error needs a bit more debugging.

Related: would you be able to post your Dockerfile and/or describe your app setup? It would be useful to find ways to optimize the Docker build to reduce the image size.

@sudhir.j I just tried `fly deploy` again and had the same error. Here is the full output:

```

@jsierles The repo takes the hellofly python example and adds scikit learn in order to serve a small model for prediction. Scikit learn is pretty big, which makes the image size large. Just to be sure it wasn’t on my end I tried deploying the same code on Heroku and it worked without any changes. Not sure what I may be doing wrong.

@rob-gordon I’ve moved this error out of the old topic, since it doesn’t seem to be related to image size or registry reliability.

Will you try building and pushing the image manually to see if you have the same issue? You can do something like this:

```auto
docker build . -t registry.fly.io/testing-the-hellofly-app:testing
flyctl docker auth
docker push registry.fly.io/testing-the-hellofly-app:testing
flyctl deploy -i registry.fly.io/testing-the-hellofly-app:testing

```

@kurt Gave this a try today but got hung up with the following-

```auto
❯ flyctl docker auth
Error: unknown command "docker" for "flyctl"
Run 'flyctl --help' for usage.

```

🤔

Doh, I meant `fly auth docker`.

Had no problems pushing that way 👍

I couldn’t get it to deploy, but I’m sure it’s because my `fly.toml` is misconfigured. The server runs on port 5000 but the fly health checks don’t seem to find it. Do you know what the problem might be?

I noticed two issues with your config

1. `services.internal_port` should be 5000 to match your app.
2. you don’t need the `services.ports` block for 5000 unless you want to expose that port externally, such as [yourapp.com:5000](http://yourapp.com:5000)
