Ever needed a robust, highly available MongoDB setup that spans multiple Kubernetes clusters on GCP? This step-by-step guide shows you how to deploy the Percona Operator for MongoDB in two GKE clusters, linking them using Multi-Cluster Services (MCS) for seamless cross-cluster discovery and connectivity. Step 1: Prepare your GKE clusters & enable MCS 1. Prepare […]

Percona Everest has always aimed to simplify running databases on Kubernetes. Previously, importing existing data into a new Everest database cluster required doing some tasks outside the platform, as there was no built-in way to handle it. That changes with Data Importers, a new, extensible framework introduced in Percona Everest 1.8.0 that lets you define […]

When running MongoDB replica sets in containerized environments like Docker or Kubernetes, making nodes reachable from inside the cluster as well as from external clients can be a challenge. To solve this problem, this post will explain the Horizons feature of Percona Server for MongoDB. Let’s start by looking at what happens behind the scenes […]

Percona Everest is a free and open source tool for running and managing databases like PostgreSQL, MySQL, and MongoDB inside Kubernetes. It simplifies things by providing three ways to work with your databases: a web interface (UI), a set of commands (API), and direct access through Kubernetes itself using built-in tools like kubectl. Note: Before […]

As a member of the Kubernetes Certified Services Provider program, Percona is now part of a select, “pre-qualified tier of vetted service providers who have deep experience helping enterprises successfully adopt Kubernetes…” Kubernetes (frequently abbreviated as K8s) has come a long way over the past decade. From being used almost exclusively for orchestrating stateless container […]

Let’s be honest: Getting MongoDB up and running quickly in the cloud sounds fantastic. Services like MongoDB Atlas promise easy deployment, automated scaling, and hands-off management on AWS, Azure, and GCP. For teams looking to shed operational burdens, the appeal is tempting. Click a few buttons, get a database… what’s not to like? However, as […]

Monitoring your databases is critical, especially in Kubernetes environments where visibility and automation are key. That’s why, in Percona Everest 1.6.0, we introduced a highly requested feature: the ability to automatically deploy Percona Monitoring and Management (PMM) as part of the Everest Helm chart using just one flag. This simplifies the process for teams who […]

If you’ve tried running MongoDB on Kubernetes, you’ve likely run into some unique challenges. Stateful workloads like replica sets and sharded clusters can be messy in containers, and things that should be easy, like backups, scaling, failovers, and upgrades, suddenly take more time and attention than they should. That’s exactly what good MongoDB Operators are […]

When using the Percona Operator for MySQL based on Percona XtraDB Cluster (PXC), it’s common to encounter scenarios where cluster nodes request a full State Snapshot Transfer (SST) when rejoining the cluster. One typical scenario where a State Snapshot Transfer (SST) is required is when a node has been offline long enough that the GCache […]
