After weeks of industry rumors and leaks to the press, on January 11 Harness announced that it had purchased the assets of Armory. Harness says this news “Powers [the] Future of Software Delivery” but what was (and was not) announced suggests otherwise. I’d like to share my take on what is happening and what it means […]

Introduction DevOps methodologies have evolved over the years. And so have the deployments. Today, as businesses are increasingly transitioning to multi-cloud or cloud-first strategies, deployments are far more automated as well as complex than they used to be a decade ago. Additionally, the increasing demand for microservices requires businesses to use tools like Kubernetes. This […]

Introduction The world of server infrastructure has become complex. Microservices and distributed cloud architectures have contributed to this complexity. With the rise in complexity, so has risen the number of failures. And operating in such complex environments is challenging. Production failures impact both businesses and customers. Modern organizations have implemented SRE to ensure these outages […]

In Part 1 of this blog series, I explained how to automate increasing the limits/requests for a pod’s memory/cpu using the ‘webhook alerts’ feature of alert manager and ‘webhook triggered pipelines’ of spinnaker. In Part 2, we explained how to use verticalpodautoscaler (VPA) to get the recommendations for pod memory and CPU requests as well as limits. In part […]

Problem Introduction: In Part 1, We have seen how to automate the process of increasing the limits/requests for the pods memory/cpu using the webhook alerts feature of alert manager and webhook triggered pipelines of spinnaker. But what value should we patch? How to decide on the optimal values for cpu/memory as these values varies from application […]

Businesses have rapidly embraced GitOps as a standard Kubernetes deployment strategy as it helps them deploy applications in the shortest possible time. This is enabled by Argo, the most popular GitOps tool for rapid deployments. Argo Rollout, a reliable Progressive Delivery tool for Kubernetes, provides deployment strategies like blue-green and canary deployments. Thus, with GitOps, […]

Problem Introduction: Kubernetes does a good job in self healing and application recovery from failure. New pods come up in the place of pods that crash. One reason for pods failing in kubernetes cluster is the memory consumed exceeding the limit set. In this case, kubernetes pods are OOM killed ( out of memory) and […]

Introduction Modern software delivery demands that infrastructure should be automated, and delivery must be continuous. Spinnaker and Terraform are two outstanding open-source tools that complement each other and play an important role in the software delivery value chain . The former is a Continuous Delivery (CD) tool, and the latter is an infrastructure provisioning automation […]

What is Kubernetes? Kubernetes is a container orchestration framework that was developed by Google to manage docker containers. Kubernetes helps to manage applications that are running on hundreds or thousands of container environments. It can also manage applications running in different environments, like physical machines, virtual machines, or even hybrid deployment environments. Why Spinnaker for […]

Jenkins as a butler for your build activities There is no doubt that Jenkins is essentially the most popular Continuous Integration (CI) tool in the world. Today, many organizations have extended it to handle Continuous Delivery (CD) but with mixed results. The time and effort required to develop, manage, and maintain Jenkins scripts, plugins, and pipelines can […]

To leverage the potential opportunities for managing a pipeline on spinnaker through the ease of a messenger platform, we will need to configure SlackOps. It is essential that a Slackbot is configured first before it can perform the assigned activities. What are Slackbots? A Slackbot is a type of Slack App designed to interact with […]
