Compatibility Matrix Cluster Add-ons (Alpha)

This topic describes the supported cluster add-ons for Replicated Compatibility Matrix.

Overview​

Replicated Compatibility Matrix enables you to extend your cluster with add-ons, to make use of by your application, such as an AWS S3 object store. This allows you to more easily provision dependencies required by your application.

CLI​

The Replicated CLI can be used to create, manage and remove cluster add-ons.

Supported Add-ons​

This section lists the supported cluster add-ons for clusters created with Compatibility Matrix.

object-store (Alpha)​

The Replicated cluster object store add-on can be used to create S3 compatible object store buckets for clusters (currently only AWS S3 is supported for EKS clusters).

Assuming you already have a cluster, run the following command with the cluster ID to create an object store bucket:

$ replicated cluster addon create object-store 4d2f7e70 --bucket-prefix mybucket
05929b24    Object Store    pending         {"bucket_prefix":"mybucket"}
$ replicated cluster addon ls 4d2f7e70
ID          TYPE            STATUS          DATA
05929b24    Object Store    ready           {"bucket_prefix":"mybucket","bucket_name":"mybucket-05929b24-cmx","service_account_namespace":"cmx","service_account_name":"mybucket-05929b24-cmx","service_account_name_read_only":"mybucket-05929b24-cmx-ro"}

This will create two service accounts in a namespace, one read-write and the other read-only access to the object store bucket.

Additional service accounts can be created in any namespace with access to the object store by annotating the new service account with the same eks.amazonaws.com/role-arn annotation found in the predefined ones (service_account_name and service_account_name_read_only).
