This section describes which are the pre-requisites to access the service and how to get started.

This is a pilot service and it is part of the validation phase of the Managed Kubernetes Service at ECMWF side.

If you want to have access, please open a ticket at the EWC Support Portal


Pre-requisites

The following pre-requisites need to be satisfied in order to start using the service.

  1. Request access to the ECMWF OpenStack API and received the Openstack application credentials accordingly.
  2. Request access to the Kubernetes service via ticket on the EWC Support Portal (this ensure also the necessary permissions have been granted).
  3. Available resources quota in the OpenStack project to deploy the cluster (control plane and worker nodes).

Access via OpenStack command-line client

Once the pre-requisites are met, it is possible to use the service via the OpenStack command-line client .

In order to get started it is possible to follow the steps below:

  1. If not yet done, install the OpenStack command-line client
  2. Install the Magnum python client plugin , e.g. via pip :
    pip install python-magnumclient
  3. Make sure the environment is correctly setup for authenticating to OpenStack via the application credentials (sourcing "openerc.sh" file or by installing the "clouds.yaml" file)
  4. Have registered a SSH keypair on OpenStack


Test the command-line client setup and the Magnum plugin:

openstack coe cluster list


If the setup is successful, it is possible to start using the service as described in the cluster provisioning and management documentation sections.


Access via Terraform/OpenTofu

The Kubernetes service can be used also by leveraging Infrastructure as Code (IaC) tools such as Terraform or OpenTofu.

Such tools supports the interaction with the OpenStack API services, including Magnum, via the terraform-provider-openstack .

In order to get started with such access, it is recommended to check the EWC documentation page IaC via Terraform and OpenTofu .
