Managing the default user's username and password

When you create a Redis™ Database Instance, you have to specify a user. It will be created with set permissions.

You can specify a name for this user when you create a Database Instance. This allows you to ensure the username is compatible with different software integrations where specific usernames are not supported.

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
A valid API key
Downloaded and installed the Scaleway CLI
Configured your environment variables (optional)

Specifying a name for a user

Follow the create a Database Instance procedure.

Tip

You can also define a username when you create a Redis™ Database Instance via the Scaleway console.

You are required to specify a username and password for the default user in your POST request payload.

Important

For a username to be valid, it must:

contain only letters, numbers, hyphens, dollars, and underscores
be between 1 and 63 characters long
not start with _rkv
start with a letter
not be scalewayadmin or metrics

Retrieving the default username

You can retrieve the default username via the API and the CLI.

Run the following curl command in a terminal to GET information about your Redis™ Database Instance of choice and retrieve the default username. Replace zone and cluster_id in the path with the zone and cluster ID of your Database Instance of choice.

curl -X GET \
-H "X-Auth-Token: $SCW_SECRET_KEY" \
'https://api.scaleway.com/redis/v1/zones/{zone}/clusters/{cluster_id}'

Run the following command in a terminal to GET information about your Redis™ Database Instance. Replace <cluster_id> with the ID of your Database Instance of choice.

scw redis cluster get <cluster-id>

A response like the following is returned:

{
"id": "string",
"name": "string",
"project_id": "string",
"status": "string",
"version": "string",
"endpoints": [],
"tags": [],
"node_type": "string",
"created_at": "string",
"updated_at": "string",
"tls_enabled": "boolean",
"cluster_settings": [],
"acl_rules": [],
"cluster_size": "integer",
"zone": "string",
"user_name": "redis-admin",
"upgradable_versions": []
}

Important

The example above is a simplified version of the response. strings and boolean are replaced with actual values in a real response.

You can find the default username under "user_name":. In this example, the default username is redis-admin.

Changing the default username

You can change the username and password of the default user anytime via the API and the CLI.

Run the following curl command in a terminal to update your Redis™ Database Instance. Replace zone and cluster_id in the path with the zone and cluster ID of your Database Instance of choice. In the body of the request, replace <your-new-username> and <your-new-password> with your username and password of choice.

curl -X PATCH \
-H "X-Auth-Token: $SCW_SECRET_KEY" \
-H "Content-Type: application/json" \
-d '{
  "user_name":"<your-new-username>",
  "password":"<your-new-password>"
  }' \
"https://api.scaleway.com/redis/v1/zones/{zone}/clusters/{cluster_id}"

A response including the information of your Database Instance appears to indicate the update was successful.

Run the following command in a terminal to GET information about your Redis™ Database Instance. Replace <cluster_id> with the ID of your Database Instance of choice. Replace <cluster-id> with your Database Instance ID, and <your-new-username> and <your-new-password> with your username and password of choice.

scw redis cluster update <cluster-id> user-name="<your-new-username>" password="<your-new-password>"
