Declarative Cluster Lifecycle Management

Every Kubernetes user is familiar with the kubectl apply command. This is used to create or modify Kubernetes resources as defined in a manifest file.

This pattern is referred to as Declarative usage where the state of the resource is "declared" in the manifest file and the command is used to implement the declared state. Unlike an imperative approach where the user needs to specify both what and how to perform a task, with the declarative approach, the user just needs to specify what to do and not worry about how to do it.

The apply approach is preferred and recommended because it is well suited for version control. The kubectl apply command works extremely well for resources inside the Kubernetes cluster.

What if there was a way to bring this declarative approach for cluster lifecycle management as well?

Auto Inject Project Name in Cluster Labels

In our July 2023 release, we added support automatic injection of project name as a cluster label. In Kubernetes, labels are key/value pairs that are attached to objects such as Pods, nodes etc.

Support for labels in Kubernetes ends at a node level. We extended the "label" construct to clusters over two years back as cluster labels. Cluster labels are critical for multi cluster workflows and have been the backbone of several unique and differentiated features in the Rafay Kubernetes Operations Platform.

In this release, we have automated the injection of the "name of the project" as a cluster label to all clusters in the project. Read on to understand some of the use cases that are enabled by this feature.

Cluster Labels

Note

In a separate blog, we will describe how cluster labels powers various multi cluster workflows and operations.

Display Workload's Details for Enhanced Developer Experience

Many of our customers are platform teams that are focused on providing their end users (application developers) a great developer experience especially with ease of use with deploying and managing their applications on remote clusters. In our July 2023 release, we have enhanced the existing developer experience further by providing developers with a facility to quickly verify details about the workload under management.

This enhancement was requested by multiple enterprise customers.

AWS Cross Account Support for EKS LCM in Rafay

Our recent release update in July to our Preview environment adds support for a number of new features and enhancements. This blog is focused on Cross Account Role ARN Support for Amazon EKS.

In July 2023, Rafay introduced a new feature to its Kubernetes Operations Platform: Cross Account Role ARN support for Amazon Elastic Kubernetes Service (EKS). This feature is designed to cater organizations that operate multiple AWS accounts, providing a seamless and efficient way to manage EKS clusters across these accounts. In this blog post, we'll delve into the significance of this enhancement, explore its use cases, and understand how it simplifies EKS cluster management across multiple AWS accounts.

Integrated FinOps Role for Cost Management

In our June 2023 release, we added support for a new turnkey role in the Rafay Kubernetes Operations Platform specifically targeted at users in a FinOps function.

This new role allows the FinOps team to access and view cost and usage data in the Rafay Kubernetes Operations Platform. Users with this role do not have the ability to impact infrastructure or applications.

Kubernetes v1.27 for Rafay MKS

Our recent release update in June adds support for a number of new features and enhancements. This blog is focused on support for Kubernetes v1.27 with Rafay MKS (i.e. upstream Kubernetes for bare metal and VM based environments).

Both new cluster provisioning and in-place upgrades of existing clusters are supported. As with most Kubernetes releases, this version also deprecates and removes a number of features. To ensure there is zero impact to our customers, we have made sure that every feature in the Rafay Kubernetes Operations Platform has been validated on this Kubernetes version.

Rafay's AI Hackathon 2023: Advancements To Improve Our Customer Experience

We just wrapped up our annual hackathon earlier this month. The theme and focus for this hackathon was AI and Generative AI and our teams had the opportunity to prototype and demonstrate fascinating solutions esp. based on Generative AI.

We had eleven (11) fully functioning submissions spanning both "external" and "internal" use cases. The panel that reviewed and judged the submissions observed extensive use of the following technologies associated with Generative AI.

Org-wide Dashboards for OPA Gatekeeper

In our recent release in May, we enhanced our turnkey integration with OPA Gatekeeper. In this blog, I describe why we worked on this enhancement.

Many of our customers that operate mission critical applications on Kubernetes clusters have to comply with organizational policies and best practices. These customers depend on and use Rafay's turnkey integration with OPA Gatekeeper in the Rafay Kubernetes Operations platform.

Prior to this release, our customers would use Rafay to

  • Centrally orchestrate and enforce OPA Gatekeeper policies, and
  • Centrally aggregate OPA Gatekeeper violations in the audit logging system

They would then use Rafay's audit log aggregator to push the OPA violations in real time to their corporate SIEM such as Splunk etc.

Since most "Infrastructure and Operations" personnel and "App Developers" are not provided access to the corporate SIEM, they have been asking Rafay to develop dashboards that will help them answer some critical questions related to compliance with policies.

What is my current posture (i.e. summary) and how has my posture evolved over time? (i.e. trend)?

Create Git Pipeline on Rafay in 3 easy steps

Rafay’s Kubernetes Operations Platform includes a GitOps service that enables infrastructure orchestration (Infra GitOps) and application deployment (App GitOps) through multi-stage, git-triggered pipelines. In this blog post, we will discuss setting up a simple pipeline to sync cluster configuration to a Git repo in 3 easy steps.

In this example, we will start with a brownfield cluster that we will import and convert to a ‘Rafay managed’ cluster. We will then initiate a ‘system sync’ operation to write back the cluster configuration to a specified Git repo.
