Prometheus, an open-source monitoring, and alerting toolkit is becoming the most popular solution for monitoring Kubernetes cluster for Spinnaker users or otherwise. To perform manual or automated Red/Black or Canary analysis, having a useful monitoring solution is essential.
In this blog, we will provide instructions on how to enable Prometheus monitoring for your Kubernetes cluster Continue reading “How to Enable Prometheus Monitoring for Kubernetes Cluster”
Docker containers have enabled applications to be developed and deployed faster due to its superior portability between development and production environment and across multiple clouds. Enterprises have started adopting Docker with microservices architecture for their new applications. One of the emerging requirements apparent among these early adopters is the need to seamlessly update versions of the microservices in production. To address this need, container orchestration systems like Kubernetes, Docker Swarm, Mesos, and Nomad has introduced support for rolling updates. In a rolling update (Figure 1), applications are updated with zero downtime by incrementally updating pods/container instances with the new version.

In this blog, we will discuss how to achieve safer rolling update of Docker applications in a Kubernetes environment through automated in-depth analysis of the microservices updates. Continue reading “Safer Rolling Update for Docker Applications with Kubernetes”
