Ensure High Availability and Uptime With Kubernetes Horizontal Pod Autoscaler and Prometheus

Stefan Prodan

Not all systems can meet their SLAs by relying on CPU/memory usage metrics alone, most web and mobile backends require autoscaling based on requests per second to handle any traffic bursts. This step by step guide shows you how to set up Kubernetes Horizontal Pod Autoscaler with Prometheus defined custom metrics, to fine tune your application monitoring and ensure high availability.

GitOps Part 4 - Application Delivery Compliance and Secure CICD

Alexis Richardson

Part 4 of the GitOps blog series explains how you can make your continuous delivery pipeline more secure using 3 best practices which enables auditing and compliance. This is aimed at Kubernetes users who have adopted Continuous Integration (CI) and who want to add Continuous Deployment (CD) to their pipeline.

Keeping Helm changes consistent and reliable with Weave Flux

Michael Bridgen

While Helm helps with getting applications running, you need other tooling to keep them up to date when something changes. Check out our alpha release of our Helm integration in Weave Flux. It makes sure your Helm chart releases are kept up to date with what’s in Git. You can try it out using the published repository in Github.

How secure is your CICD pipeline?

Alexis Richardson

Looking at a CICD pipeline with security in mind, reveals some interesting concerns. Consider the credentials and access typically assigned to each step, and what’s actually required for each step - Read Write access, and Read Only access. The CI system can be a target, because it’s got credentials for the source code, the image repo and the cluster, and it crosses two logical security boundaries. Learn how you can mitigate this with a GitOps approach.

GitOps: High velocity CICD for Kubernetes

Alexis Richardson

This blog post explains techniques for development teams who strive for high velocity continuous delivery using Kubernetes and Docker. When we say “high velocity” we mean that every product team can safely ship updates many times a day — deploy instantly, observe the results in real time, and use this feedback to roll forward or back. The goal is for product teams to use continuous experimentation to improve the customer experience as fast as possible.

Storing Secure Sealed Secrets using GitOps

Cezzaine Zaher

Sealed Secrets is a Kubernetes Custom Resource Definition Controller which allows you to store even sensitive information (aka secrets) in Git, which previously has not been an option. In addition, you can use Weave Cloud’s Deploy feature in conjunction with Sealed Secrets to create a continuous deployment pipeline where all operations are git based and where the desired state of your apps is declared in your git repos including your secrets.
