A Guide On The Installation Of Spinnaker in Kubernetes Cluster

Spinnaker is an open-source, multi-cloud deployment tool for releasing software changes reliably. You can deploy and automate your application release across multiple cloud environments including Kubernetes, AWS EC2, Google Computer Engine, Google App Engine, Microsoft Azure and many more.

Kubernetes Deployments 101

In another article, we discussed Kubernetes ReplicaSets. ReplicaSets, however, have one major drawback: once you select the pods that are managed by a ReplicaSet, you cannot change their pod templates. So for example, if you are using a ReplicaSet to deploy four pods with NodeJS running and you want to change the NodeJS image to a newer version, you need to delete the ReplicaSet and recreate it. Restarting the pods causes downtime till the images are available and the pods are running again.

How to Create a Kubernetes Security Policy

Kubernetes is an incredibly powerful container management tool. If you've worked with containers long enough, you know that security has to take a central role in the deployment of your apps and services. Without locking down those containers, havoc could be wreaked on your network.

You certainly don't want that.

So, what can you do? With Kubernetes you should consider establishing pod security policies

Migrating applications to containers and Kubernetes: 5 best practices

We recently shared 7 best practices on building applications specifically for containers and Kubernetes. But what if you’re considering containerizing an existing app? This comes with a different set of considerations and recommendations.

Among other advice we’ll get to momentarily: Just because you can do it doesn’t always mean you should, and that evaluation is a must-do for just about any team. If you do determine there’s value in moving an existing application to a containers-and-orchestration model, then the rest of the work begins.


Top Six Open Source Tools for Monitoring Kubernetes and Docker

Kubernetes and Docker are two of the most commonly heard buzzwords in modern DevOps conversations. Docker is a tool that enables you to containerize and run your applications, and Kubernetes provides you with a platform to orchestrate or manage these containers—since managing thousands of containers manually using the Docker CLI would be a practical nightmare.

A Use Case to Secure Kubernetes Network Connections

One of the stumbling blocks organizations typically experience when making the shift to a Kubernetes and microservices infrastructure is sharing and securing data dynamically.
In a traditional monolithic infrastructure, a single firewall structure previously largely sufficed to confine and monitor data and to manage the security layers within a single perimeter. However, applications and data shared between and within Kubernetes clusters typically extend between different cloud and on-premises environments.
