+# scaleway_redis_cluster
+
+Creates and manages Scaleway Redis Clusters.
+For more information, see [the documentation](https://developers.scaleway.com/en/products/redis/api).
+
+## Examples
+
+### Basic
+
+```hcl
+resource "scaleway_redis_cluster" "main" {
+  name = "test_redis_basic"
+  version = "6.2.6"
+  node_type = "MDB-BETA-M"
+  user_name = "my_initial_user"
+  password = "thiZ_is_v&ry_s3cret"
+  tags = [ "test", "redis" ]
+  cluster_size = 1
+  tls_enabled = "true"
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+- `version` - (Required) Redis's Cluster version (e.g. `6.2.6`).
+
+~> **Important:** Updates to `version` will migrate the Redis Cluster to the desired `version`. Keep in mind that you cannot downgrade a Redis Cluster.
+
+- `node_type` - (Required) The type of Redis Cluster you want to create (e.g. `MDB-BETA-M`).
+
+~> **Important:** Updates to `node_type` will migrate the Redis Cluster to the desired `node_type`. Keep in mind that you cannot downgrade a Redis Cluster.
+
+- `user_name` - (Required) Identifier for the first user of the Redis Cluster.
+
+- `password` - (Required) Password for the first user of the Redis Cluster.
+
+- `name` - (Optional) The name of the Redis Cluster.
+
+- `tags` - (Optional) The tags associated with the Redis Cluster.
+
+- `zone` - (Defaults to [provider](../index.md) `zone`) The [zone](../guides/regions_and_zones.md#zones) in which the Redis Cluster should be created.
+
+- `cluster_size` - (Optional) The number of nodes in the Redis Cluster.
+
+~> **Important:** You can set a bigger `cluster_size`, it will migrate the Redis Cluster, but keep in mind that you cannot downgrade a Redis Cluster so setting a smaller `cluster_size` will not have any effect.
+
+- `tls_enabled` - (Defaults to false) Whether TLS is enabled or not.
+
+- `project_id` - (Defaults to [provider](../index.md) `project_id`) The ID of the project the Redis Cluster is associated with.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+- `id` - The ID of the Database Instance.
+- `created_at` - The date and time of creation of the Redis Cluster.
+- `updated_at` - The date and time of the last update of the Redis Cluster.
+
+
+## Import
+
+Redis Cluster can be imported using the `{zone}/{id}`, e.g.
+
+```bash
+$ terraform import scaleway_redis_cluster.redis01 fr-par/11111111-1111-1111-1111-111111111111
+```
