In this post, I will be covering up Kubernetes Best Practices. As we all know that how big and popular is Kubernetes and we are witnessing that Kubernetes is complex, and it is getting more complex each day. And I believe that you might have come across some posts somewhere about how Kubernetes is overkill for what you need.
Now we’re in 2021 and you believe it or not that cloud-native and Kubernetes technologies will continue to be essential tools than ever before

On one particular area that people should really focus on Kubernetes best practices in 2021 and probably beyond this year. Yes, I see that some people are really not taking it much seriously and following best practices allows you to use it in production to deploy and manage apps at scale.
Here are some of the most popular videos about best practices for Kubernetes on Google Cloud Platform.
1. How and why to build small container images?
In this video of Kubernetes Best Practices, Sandeep Dinesh shows how you can build small containers to make your Kubernetes deployments faster and more secure and explore how to create production-ready container images using Alpine Linux and the Docker builder pattern, and then run some benchmarks that can determine how these containers perform inside your Kubernetes cluster.
2. Organizing with Namespaces
Let’s take a look at how Kubernetes Namespaces can make managing your Kubernetes resources easier. Namespaces provide a powerful way to manage resources in Kubernetes and provide the foundation for policies and management.
3. Setting up health checks with readiness and liveness probes
Health checks are required to create robust and reliable services. Let’s learn about the subtleties of readiness and liveness probes, when to use which probe, and how to set them up in your Kubernetes cluster.
4. Setting resource requests and limits
Kubernetes gives you a powerful platform to run your services, but if you don’t define rules around resources, eventually you are going to be in for a bad time. Let’s take a look at how you can solve these problems using resource requests and limits.
5. Terminating with grace
Pods and Containers in Kubernetes need to deal with termination gracefully. Let’s take a look at how you can help Kubernetes do its job more efficiently and reduce the downtime your applications experience.
6. Mapping external services
Let’s learn how to leverage Kubernetes’ built-in service discovery mechanisms for services running outside the cluster, just like you can for services inside the cluster! This gives you parity across your dev and prod environments, and if you eventually move the service inside the cluster, you don’t have to change your code at all.
7. Upgrading Kubernetes cluster with zero downtime
One of the most important things you need to do is keep your cluster up to date. Let’s take a look at how Google Kubernetes Engine can make upgrading your Kubernetes cluster painless!
That’s all, for now, folks and I believe and hope that this post helped you to understand some of the best Kubernetes practices using GKE or Google Kubernetes Engine on Google Cloud Platform. Please like it and share it.
