Kubernetes Cluster Installation

For a customer-controlled environment, you (the customer) are responsible for installing the Kubernetes cluster and to ensure that the configuration of the Kubernetes cluster meets the requirements before meeting with SAP. To help you identify the many considerations when planning your Kubernetes cluster, we recommend that you review the questionnaire for customer-controlled deployments.

The following is an overview of the steps to install your Kubernetes cluster.

1. Check to see if the Kubernetes distribution or cloud provider you plan to use is supported for the latest broker version. For more information see Supported Kubernetes Versions.

2. Ensure that your Kubernetes cluster fulfills the prerequisites which are required to install advanced event mesh. SAP recommends that you use these best practices:

   • Configure the resources required for your Kubernetes cluster.

   • If you are using one of the following cloud providers, you must use the resources defined as documented:

     • Installing in Azure Kubernetes Service (AKS)

     • Installing in Amazon Elastic Kubernetes Service (EKS)

     • Installing in AWS Outposts

     • Installing in Google Kubernetes Engine (GKE)

     • Installing in Alibaba Cloud Container Service for Kubernetes (ACK)

   • Use best practices to configure the Kubernetes cluster to optimally operate advanced event mesh. SAP recommends that you use these best practices when possible:

     • Use multiple zones as this ensures reliability for High-Availability event broker services and a loadbalancer as described in Availability Zones and Deployment Architecture for Kubernetes

     • Schedule workloads to appropriately-scaled-Node Pool using nodeSelector and the recommended labels/taints. For more information, see Schedule Workload to Appropriately-Scaled Node Pool and Using nodeSelector

     • We also support tolerations. For more information, see Support for nodeSelector, Labels, Taints, and Tolerations.

   We provide reference Terraform projects for deploying a Kubernetes cluster to AKS, EKS, and GKE. These Terraform projects have the recommended configuration settings, such as worker node sizes, resource configurations, taints, and labels optimized to install advanced event mesh.
   
   You can download the reference Terraform projects from the following GitHub repository: https://github.com/SolaceLabs/customer-controlled-region-reference-architectures
   
   Beware that all sample scripts, Terraform modules, and examples are provided as-is. You can modify the files as required and are responsible for maintaining the modified files for your Kubernetes cluster.

After following these steps, your Kubernetes cluster is ready to set up the Kubernetes connectivity so that you can deploy advanced event mesh.
