Best Practices, Tools, and Approaches for Kubernetes Monitoring

In a Kubernetes environment, applications operate across multiple nodes within a cluster, and application services can be distributed across multiple clusters and multiple clouds, making tracking the health of an application and the infrastructure it depends on quite challenging.

Kubernetes monitoring is the process of gathering metrics from the Kubernetes clusters you operate to identify critical events and ensure that all hardware, software, and applications are operating as expected. Aggregating metrics in a central location will help you understand and protect the health of your entire Kubernetes fleet and the applications and services running on it.

Kubernetes is the industry-standard technology used by enterprises to deliver microservices-based container orchestration platforms. The Kubernetes ecosystem is growing rapidly and has a vibrant community that has built several free open-source tools and extensions to make it easier to run your workloads. This article will explain some of the more popular open-source Kubernetes tools used for development, monitoring, and deployment purposes that can improve your cloud-native experience.

Getting Started With Kubernetes In 2 Days

Kubernetes (commonly abbreviated as K8s) is an open-source platform for container orchestration that we use extensively at Shipyard. It automates many of the tasks involved in maintaining a container-based app, such as deploying, scaling, load-balancing, and auto-scaling.

Kubernetes Done Wrong

Kubernetes is a major asset for modern container management and has streamlined deployment for thousands of companies. However, it is infamous for its steep learning curve. Simply put, Kubernetes is difficult to get right.

7 Best Log Management Tools for Kubernetes [2020]

You may be wondering why you should bother with Kubernetes' log management tools?

Kubernetes dominates the container orchestration market and is often used to host microservices. Each instance of a microservice generates large numbers of log events that can quickly become difficult to manage.  But worse, when something goes wrong, finding the root cause can be tough due to the complex interactions between services and the near-infinite number of possible failure modes. This potential for trouble has fueled the popularity of log management tools for Kubernetes.

Drive Continuous Delivery (CD) on Kubernetes With GitOps

In software engineering, there’s always a new technology that everyone’s talking about:

  • Way back when everything started (around 2006), it was cloud computing.
  • In 2015, it was Kubernetes 1.0.
  • Next, everyone wanted to jump on the boat known as GitOps, which was first publicized by Weaveworks in 2017 in a blog by Alexis Richardson (Co-founder and CEO of Weaveworks, and chairman of the Cloud Native Computing Foundation (CNCF) Technical Oversight Committee (TOC)).
  • Most recently, on April 7, 2020, the CNCF TOC voted to accept the Argo Project (a set of Kubernetes-native tools for running and managing jobs and applications on Kubernetes) as an incubation-level hosted project. Part of the Argo Project is Argo CD, which provides support for declarative GitOps-based deployment of any Kubernetes resource.

At nClouds, we care about GitOps because we strive to use the latest and greatest technologies where they help our clients deliver innovation faster. It’s one of our core values at nClouds: Innovation culture that delivers client value. And we’re using Argo CD, a GitOps continuous delivery tool for Kubernetes.

OpenTracing in NodeJS, GO, Python: What, Why, How?

In previous blogs, we described how to optimize the deployment of applications and utilize guardrails for applications. These guardrails covered:

One additional guardrail in managing your application is to properly implement "Observability". As it turns out, observability is more important than ever because of the shift in application architecture (to a microservices architecture) and increased deployment pace (hourly/weekly vs. quarterly/yearly). Services are dynamically updated and are usually containerized. Hence, the traditional way of adding "monitoring" after the app deployment cannot scale.

50+ Useful Kubernetes Tools

Updated September 2019

In the last few years, Kubernetes has laid waste to its fellow competitors in the battlefield of container orchestration. Sadly, Docker Swarm hasn’t been a major contender since 2016 and, like AWS, admitted defeat by pledging K8s support and integration. Since Kubernetes has skyrocketed to popularity as the container solution of choice, here’s a comprehensive list of all the tools that complement K8s to further enhance your development work.

How to Run Apache Cassandra on Kubernetes

With Kubernetes’ popularity skyrocketing and the adoption of Apache Cassandra growing as a NoSQL database well-suited to matching the high availability and scalability needs of cloud-based applications, it should be no surprise that more developers are looking to run Cassandra databases on Kubernetes. However, many devs are finding that doing so is relatively simple to get going with, but considerably more challenging to execute at a high level.

On the positive side, Kubernetes helpfully offers StatefulSets — workload API objects that can be used to manage stateful applications. StatefulSets provide the requisite components to establish stable and unique network identifiers, stable persistent storage, smooth and ordering deployment and scaling (as well as deletion and termination), and automated rolling updates.
