How to create, manage, and delete a Containers namespace

This page shows you how to create and manage a Serverless Containers namespace. Namespaces allow you to group your containers and share environment variables between them.

Before you start

To complete the actions presented below, you must have:

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization

Creating a Serverless Containers namespace

1. Click Containers in the Serverless section of the side menu. The list of your containers namespaces displays.
2. Click Create namespace. If you have no existing Serverless Containers resources in your current Project, click Deploy container.
3. Complete the following steps in the wizard:
   • Enter a name, and optionally a description for your namespace. The name must only contain alphanumeric characters and dashes.
   • Choose a region, which is the geographical location in which your namespace will be deployed.
   • Enter any environment variables required for your namespace. Environment variables configured in a namespace will be available in all containers/apps within the same namespace. For each environment variable, click +Add new variable and enter the key / value pair.
   • Set secret environment variables (optional). Secrets are environment variables that are injected into your container and stored securely, but not displayed in the console after initial validation. Add a key and a value.
   • Verify the estimated cost.
4. Click Create namespace only to finish, or click Create namespace and add container if you want to deploy a container next.

Managing a Serverless Containers namespace

Generating and managing access tokens

The Scaleway console allows you to generate authentication tokens to grant users and applications access to the containers present in your namespace.

1. Click Containers in the Serverless section of the side menu. The containers page displays.

2. Click the containers namespace you want to manage.

3. Click the Namespace settings tab. Information about the region, registry endpoint and description of your namespace display.

4. Click + Generate token to create an access token for this namespace.

   Important

   The token key will only be available for copy once. Make sure to store it securely before leaving the page.

Private containers present in your namespace now require the authentication token to be executed, as shown below:

curl -H "X-Auth-Token: <YOUR_NAMESPACE_TOKEN>" <YOUR_CONTAINER_ENDPOINT>

Adding and managing environment variables and secrets

The Scaleway console allows you to define environment variables and secrets at the namespace-level to pass to the containers present in the namespace.

1. Click Containers in the Serverless section of the side menu. The containers page displays.

2. Click the containers namespace you want to manage.

3. Click the Namespace settings tab. Information about the region, registry endpoint and description of your namespace display.

4. Add environment variables by clicking the «Edit Icon» icon, + Add variable, entering the key/value pair, and clicking «Validate Icon».

5. Add secrets by clicking the «Edit Icon» icon, + Add secret, entering the key/value pair, and clicking «Validate Icon».

The environment variables and secrets defined will now be passed to your containers. Every container in a ready state is redeployed to take the change into account.

Deleting a Serverless Containers namespace

1. Click Containers in the Serverless section of the side menu. The containers page displays.

2. Click the «See more Icon» icon next to the namespace you want to delete, and select Delete from the drop-down menu.

3. Type DELETE in the pop-up that asks you to confirm the action, then click Delete namespace.
