Implementing Canary Releases on Kubernetes with Spinnaker, Istio, and Prometheus

In a microservices world, applications consist of dozens, hundreds, or even thousands of components. Manually deploying and verifying deployment quality in production is virtually impossible. Kubernetes, which natively supports rolling updates, enables blue-green application deployments with Spinnaker. However, the gradual rollout is a feature that doesn’t come out-of-the-box but can be achieved by adding Istio and Prometheus to the equation.

Kubernetes RBAC 101: Overview

Cloud native and open source technologies have modernized how we develop software, and although they have led to unprecedented developer productivity and flexibility, they were not built with enterprise needs in mind. A primary challenge is bridging the gap between cloud native and enterprise reality. Enterprises need a centralized Kubernetes management control plane with logging and monitoring that supports security and governance requirements extended through essential Kubernetes frameworks.

Kublr 1.18 Supports in-Place Platform Upgrades and External Clusters

We are excited to announce in-place Kublr Platform upgrades and a technical preview for external cluster support. That’s yet another step in making enterprise-grade Kubernetes adoption a breeze. While Kublr supports automated rolling cluster updates and upgrades with zero downtime, since our last release (1.17) updating the platform itself was still a semi-manual project supported by the Kublr team. Now, all it takes is the click of a button.

Kubernetes RBAC 101

Incredibly powerful and flexible, Kubernetes role-based access control (RBAC) is an essential tool to effectively manage production clusters. Yet many Ops and DevOps engineers are still facing barriers to efficiently use it at scale. These include a steep learning curve, YAML-based configuration, lack of standardized best practices, and the general complexity of this functionality at large -- it truly can be somewhat overwhelming.
