How to deploy a container from an external container registry

Reviewed on 31 July 2023Published on 26 May 2021

This page shows you how to deploy your first Serverless Container from an external registry. A container is a package of software that includes all dependencies: code, runtime, configuration, and system libraries so that it can run on any host system. This allows you to control your production environment. Scaleway provides you with custom Docker images that are entirely handled for you in the cloud. With Serverless Containers, you can rely on your favorite technologies such as Django or Ruby on Rails. For now Serverless Containers only supports public images.

Security & Identity (IAM):

You may need certain IAM permissions to carry out some actions described on this page. This means:

  • you are the Owner of the Scaleway Organization in which the actions will be carried out, or
  • you are an IAM user of the Organization, with a policy granting you the necessary permission sets
Requirements:
  1. Click Containers in the Serverless section of the side menu. The containers page displays.
  2. Click the relevant container’s namespace.
  3. Click Deploy container. The container creation wizard displays.
  4. Complete the following steps in the wizard:
    • Select the External container registry.
    • Enter the public container image URL provided by the external registry. For example
    • Choose the Port your container is listening on. We recommend configuring your container to listen on the PORT environment variable.
    • Choose a name for your container, and optionally a description. The name must only contain alphanumeric characters and dashes.
    • Choose the resources to be allocated to your container at runtime. These define the performance characteristics of your container.
    • Set your scaling preferences, or leave them at default values. The Scaleway platform autoscales the number of available instances of your container to match the incoming load, depending on the settings you define here.
    • Define any environment variables you want to inject into your container. For each environment variable, click +Add new variable and enter the key/value pair.
    • Add secrets for your container. Secrets are environment variables which are injected into your container, but the values are not retained or displayed by Scaleway after initial validation.
    • Set the desired privacy policy for your container. This defines whether container invocation may be done anonymously (public) or only via an authentication mechanism provided by the Scaleway API (private).
    • Click Advanced Options if you wish to set a custom timeout for your container.
    • Verify the estimated cost.
  5. Click Deploy container to finish.
