### AI overview

This tutorial explains how to configure cross-site replication between two Percona Operator for MySQL clusters to create a ClusterSet environment for disaster recovery and switchover between data-center and disaster-recovery members. It covers deploying the clusters, retrieving endpoints and cluster names, transferring credentials, and initializing the DR cluster.

### Source excerpt

A while ago, we discussed the cross-site replication feature of the Percona PXC operator. Recently, a similar cross-site replication feature was introduced in the Percona (PS MySQL) operator v1.2.0, a topology based on Group Replication/InnoDB Cluster. In this blog post, we will explore how to add a DR Cluster to an existing DC Cluster to ... Continued The post Group Replication Beyond a Single Cluster: DC-DR with Percona (PS MySQL) Operator appeared first on Percona.

### AI overview

A practical tutorial on building a Kubernetes operator with Kubebuilder and Go. It creates a TodoList custom resource, implements reconciliation logic that checks pods, deploys the operator to a local kind cluster, and extends it to watch pod events.

### Source excerpt

In this post, we will be going over the fastest no-frills approach to getting your operator off the ground using kubebuilder. The post assumes knowledge of the following: Kubernetes and how it works Kubernetes custom resource definitions Kubernetes Operators and reconciliation loops Setting up a local cluster, I use kind for my k8s orchestration needs Golang The task is to create an operator that operates on a Kubernetes CRD TodoList...
