In this article, we talk about monitoring for scaling and life cycle management with the help of built-in tools like probes and horizontal pod autoscaler. A previous article covered monitoring and metrics for users using tools like the Kubernetes dashboard and cAdvisor. We will test each one of these tools to see what they offer and how they can help us.

In this article, we talk about monitoring Kubernetes with the help of built-in tools like the dashboard and cAdvisor. In part 2, we will cover scaling and life cycle management using other built-in tools like probes and horizontal pod autoscaler. We will then test each one of these to see what they offer and how they can help us.

CNI, or container network interface, is a standard system for provision networking for containers, especially for multi-host orchestrators like Kubernetes. In this article, we'll describe what CNI is, why it's helpful, and then compare some popular CNI plugins for establishing the network for Kubernetes containers.

Container monitoring environments come in all shapes and sizes. Some are open source while others are commercial. Some are available in the Rancher Catalog while others require manual configuration. Some are general purpose while others are aimed specifically at container environments. Some are hosted in the cloud while others require installation on own cluster hosts. In this post, we take an updated look at 10 container monitoring solutions. This effort builds on earlier work including Ismail Usman’s Comparing 7 Monitoring Options for Docker from 2015 and The Great Container Monitoring Bake Off Meetup in October of 2016.

For teams building and deploying containerized applications using Docker, selecting the right orchestration engine can be a challenge. The decision affects not only deployment and management, but how applications are architected as well. DevOps teams need to think about details like how data is persisted, how containerized services communicate with one another, load balancing, service discovery, packaging and more. It turns out that the choice of orchestration engine is critical to all these areas.

Note: You can find an updated comparison of Kubernetes vs. Docker Swarm in a recent blog post here. Recent versions of Rancher have added support for several common orchestration engines in addition to the standard Cattle. The three newly supported engines, Swarm (soon to be Docker Native Orchestration), Kubernetes and Mesos are the most widely used orchestration systems in the Docker community and provide a gradient of usability versus feature sets.

*Note: Since publishing this post, we’ve created a guide comparing Kubernetes with Docker Swarm. You can read the details in the blog post here..* Over the last six months, Rancher has grown very quickly, and now includes support for multiple orchestration frameworks in addition to Cattle, Rancher’s native orchestrator. The first framework to arrive was Kubernetes, and not long after, Docker Swarm was added. This week, the team at Rancher added support for Mesos.
