Limitations

Ports

You can only use one of the following ports to make your services accessible:

• 80
• 8081-8085

Internally your services listen to any port, but from the internet, only one of those can be used.

That means your “ports” section will likely look like:

    ports:
      - "80:80"

or

    ports:
      - "80:3000"

or

    ports:
      - "8081:5432"

But the number before ”:” should be one one of those mentioned above.

Architecture

You can deploy both ARM and AMD64 images, but on our current infrastructure the ARM deployments will give you better performance for the same price.

HTTPS

It might take up to one minute to generate the certificate for new HTTPS sites. Wait a bit and the SSL error will go away alone.
