Kubernetes is quickly becoming one of the most popular tools on StackShare. Our users call it the "leading Docker container management solution," and it far outranks Docker's own solution: Swarm.
When a tool is hot like this, we like to keep a close eye on it with Stack News. These are the 9 best posts we found on Kubernetes last month.

1. Google Cloud Platform releases kaniko
Typically, building Docker images requires root access to the underlying hardware. This has historically caused major headaches for developers wanting to build container images in environments like Kubernetes. Kaniko is an open source tool released by Google that solves this pain point.
2. Learn Kubernetes in Under 3 Hours
If you already have some experience with Docker and microservices, but haven't taken the plunge into the Kubernetes world yet, this one is for you. It's an excellent tutorial that starts with building a small microservice architecture on your local machine and gradually scales up to deploying your first Kubernetes cluster.
3. Kubernetes Security - Best Practice Guide
Whether you just learned how to deploy a Kubernetes cluster, or you've already been using it in production for a while, it's a good idea to make sure security is tight. The authors have saved you the pain of learning about Kubernetes security flaws the hard way with this guide.
4. We are Kubernetes Developers, Ask Us Anything!
Several members of the Kubernetes team recently hopped on Reddit to do an AMA. If you've had a burning question about Kubernetes, there's a good chance it's answered here.
5. Debugging TCP socket leak in a Kubernetes cluster
Hasura is a Kubernetes platform as a service, so it's safe to say their engineers know a thing or two about running Kubernetes in production and the issues that come along with it. Recently, they encountered an issue that was causing delayed API responses and "connection refused" errors. In this post they describe how they debugged what was ultimately a TCP socket leak.
6. Introducing Jenkins X
The makers of the most popular continuous integration tool on StackShare, Jenkins released their CI/CD solution for Kubernetes last month. Jenkins X greatly simplifies the DevOps process for cloud applications running on Kubernetes.
7. Stateful Apps on Kubernetes
The beauty of Kubernetes is the ability to spin up machines running your application in seconds - and bring them down just as quickly. But where does a persistent datastore fit into this picture? The engineers behind CockroachDB have the answer.
8. As Kubernetes grows, a startup ecosystem develops in its wake
Massively popular open source projects like Kubernetes are one reason the world will never run out of startup ideas. According to Techcrunch, $4 billion has been invested into startups based around Kubernetes and its CNCF bretheren. It doesn't seem to be slowing down, so if you have a great idea for a Kubernetes startup, now might be the time.
9. Introducing the Operator Framework
One of the startups involved in the rush of Kubernetes investment is CoreOS, who was acquired for $250M by Red Hat earlier this year. This month they released their open source toolkit for Kubernetes native applications, the Operator Framework.
