In this post, we will outline a reference architecture for setting up K3s in a High Availability (HA) configuration. This means that your K3s cluster can tolerate a failure and remain up and running and serving traffic to your users. Your applications should also be built and configured for high availability, but that is beyond the scope of this tutorial. K3s is a lightweight certified Kubernetes distribution developed at Rancher Labs that built is for IoT and edge computing.

In a previous blog we learnt about setting up a Scalable Prometheus-Thanos monitoring stack. We also learnt about how we can cluster multiple Prometheus servers with the help of Thanos and then deduplicate metrics and alerts across them. MetricFire is a Hosted Prometheus solution, and you can use our product with minimal configuration to gain in-depth insight into your environments. If you would like to learn more about it please book a demo with us, or sign up for the free trial today.

Sleuth is a deployment tracking tool that gives you a deeper level of insight into your CI/CD workflows by tracking all of your team’s deployment tools from a single dashboard. Sleuth integrates with different components of your deployment pipeline and develops an understanding of your development processes. It can then automatically alert you as to when code is shipping, when manual approvals are needed, and when failures occur.
