Across six force-deletes, the operator automatically promoted new primaries and restored all three replicas, with the article examining detection, recovery behavior, logs, and timing. ### Source excerpt In my planned failover walkthrough, I showed what happens when you deliberately move the primary role to another replica. That's the easy case. Now I want to show what happens when the primary pod just disappears unexpectedly, like during a node failure or a container crash. No graceful shutdown, no demotion, just gone. I ran two test scenarios, each cycling the primary role across all three pods by force-deleting the current primary three times in a row. First, a 5GB TPC-C database idle. Then, that same 5GB database under sustained HammerDB TPC-C load. Six force-deletes total, six successful automatic failovers. I'll walk through the error log from the promoted replica, the operator's detection and recovery behavior, and the full timing data. ## Walking Through a Planned Failover: SQL Server Always On Availability Groups on Kubernetes DevFeed: [Walking Through a Planned Failover: SQL Server Always On Availability Groups on Kubernetes]() Original publisher: [Read original article]() Author: Anthony Nocentino Published: 2026-04-19T05:00:00Z Content type: tutorial Language: en Sources: [Kubernetes on Anthony Nocentino's Blog]() Topics: [sql-server](), [Kubernetes](), [Availability]() Tags: [availability-groups](), [containers](), [failover](), [kubernetes](), [open-source](), [operator](), [sql-server]() ### AI overview A walkthrough of planned failover rotation for a three-replica SQL Server Availability Group managed by sql-on-k8s-operator on Kubernetes. It examines SQL Server error logs, operator reconciliation behavior, and timing under both an idle database and a sustained TPC-C workload. ### Source excerpt When building the sql-on-k8s-operator, I wanted to make sure it could handle both planned and unplanned failovers. The easy case is a planned failover, where you deliberately move the primary role to another replica. The harder case is an unplanned failover, where the primary pod just disappears. The operator needs to handle both. I recently ran a full planned failover rotation on a three-replica SQL Server Availability Group managed by sql-on-k8s-operator, and I want to show you exactly what happens inside SQL Server and the operator during each hop. If you've been following my Introducing the SQL Server on Kubernetes Operator post, this is the logical next step: what does the error log actually look like during a planned failover, what does the operator do in response, and how long does the whole thing take? ## Introducing the SQL Server on Kubernetes Operator DevFeed: [Introducing the SQL Server on Kubernetes Operator]() Original publisher: [Read original article]() Author: Anthony Nocentino Published: 2026-04-12T05:00:00Z Content type: tutorial Language: en Sources: [Kubernetes on Anthony Nocentino's Blog]() Topics: [Kubernetes](), [sql-server](), [Availability](), [Disaster Recovery](), [Open Source]() Tags: [automated](), [automatic](), [availability](), [availability-groups](), [containers](), [disaster-recovery](), [failover](), [high-availability](), [kubernetes](), [open-source](), [operator](), [sql-server]() ### AI overview This tutorial introduces sql-on-k8s-operator, an open-source Kubernetes operator for managing SQL Server workloads. It addresses high availability and disaster recovery by automating lifecycle management, failover, and Always On Availability Group setup, and demonstrates deployment with custom resources. ### Source excerpt Are you considering replatforming your SQL Server workload due to recent vendor changes, but still need high availability and disaster recovery? You're not alone. One of the challenges with running SQL Server on Kubernetes is that there's no Kubernetes operator available. That means no automated lifecycle management, no automatic failover, and no standard way to bootstrap an Always On Availability Group on Kubernetes. I'm excited to share it today as an open-source project: sql-on-k8s-operator. Let's go. ## Monitoring with the Pure Storage FlashArray OpenMetrics Exporter DevFeed: [Monitoring with the Pure Storage FlashArray OpenMetrics Exporter]() Original publisher: [Read original article]() Author: Anthony Nocentino Published: 2025-02-14T00:00:00Z Content type: tutorial Language: en Sources: [Kubernetes on Anthony Nocentino's Blog]() Topics: [Monitoring](), [Docker Compose](), [Prometheus](), [Grafana](), [observability](), [Docker](), [Time Series]() Tags: [compose](), [configuration](), [dashboards](), [docker](), [grafana](), [linux](), [metrics](), [monitoring](), [observability](), [open-source](), [prometheus](), [pure-storage](), [storage](), [ubuntu](), [update]() ### AI overview A tutorial on monitoring Pure Storage FlashArray with OpenMetrics, Docker Compose, Prometheus, and Grafana.

Starting with Purity//FA 6.7.x, FlashArray includes a native OpenMetrics exporter, eliminating the need for a separate exporter service/container.

It also explains Docker's deprecation as a Kubernetes runtime and provides Ubuntu installation steps. ### Source excerpt This post shows you how to install containerd as the container runtime in a Kubernetes cluster. I will also cover setting the cgroup driver for containerd to systemd, which is the preferred cgroup driver for Kubernetes. In Kubernetes version 1.20 Docker was deprecated as a container runtime in a Kubernetes cluster and support was removed in 1.22. Kubernetes 1.26 requires that you use a runtime that conforms with the Container Runtime Interface (CRI). containerd is a CRI-compatible container runtime and is one of the supported options you have as a container runtime in this post-Docker/Kubernetes world. To be clear, you use container images created with Docker in containerd. containerd will start and run the container in your Kubernetes cluster. This post was previously published in February 2021. This is an updated version with the latest installation and configuration steps. ## New Pluralsight Course - Certified Kubernetes Administrator - Working With Your Cluster DevFeed: [New Pluralsight Course - Certified Kubernetes Administrator - Working With Your Cluster]() Original publisher: [Read original article]() Author: Anthony Nocentino Published: 2024-04-28T00:00:00Z Content type: release Language: en Sources: [Kubernetes on Anthony Nocentino's Blog]() Topics: [Kubernetes](), [kubectl](), [Command-line interface](), [Deployment]() Tags: [cli](), [containers](), [deployment](), [kubectl](), [kubernetes](), [pluralsight](), [training]() ### AI overview The post announces the availability of a Pluralsight course in the Certified Kubernetes Administrator series.

You define limits as parameters when creating containers. In its default configuration, a container will have no resource constraints for accessing resources of the host operating system. This post will look at how to configure resource constraints in Docker and look at how SQL Server sees the resources when CPU and Memory resource constraints are in place. ## Updated Pluralsight Course - Managing the Kubernetes API Server and Pods DevFeed: [Updated Pluralsight Course - Managing the Kubernetes API Server and Pods]() Original publisher: [Read original article]() Author: Anthony Nocentino Published: 2021-05-11T13:59:22Z Content type: release Language: en Sources: [Kubernetes on Anthony Nocentino's Blog]() Topics: [Pluralsight](), [Kubernetes](), [API](), [Containers](), [Learning](), [Cloud]() Tags: [api](), [cloud](), [container](), [containers](), [course](), [kubernetes](), [learning](), [pluralsight](), [training]() ### AI overview The article announces an updated Pluralsight course on managing the Kubernetes API server and Pods.
