Open source projects worth checking out

kubectl trace

kubectl trace is a kubectl plugin that allows you to schedule the execution of bpftrace programs in your Kubernetes cluster.

Kondense

Kondense is an automated resource sizing tool. It runs as a sidecar in kubernetes pods.

JET Pilot

JET Pilot is an open-source Kubernetes desktop client that focuses on less clutter, speed and good looks.

Kubernetes PreUpGrade (Checker)

KubePug/Deprecations is intended to be a kubectl plugin, which:

• Downloads a generated data.json file containing API deprecation information for a specified release of Kubernetes
• Scans a running Kubernetes cluster to determine if any objects will be affected by deprication
• Displays affected objects to the user

Top 5 Kubernetes Challenges for Platform Teams

The article discusses the top five challenges platform teams face when working with Kubernetes:

• Complex Cluster Management: Managing and maintaining multiple Kubernetes clusters, especially across different environments, can be complex.
• Security: Ensuring the security of both the cluster and applications, including aspects like authentication, access control, and vulnerability management.
• Monitoring and Troubleshooting: Effectively monitoring cluster health and troubleshooting issues, particularly when failures occur.
• Resource Management: Properly configuring and optimizing resource usage to prevent waste and performance bottlenecks.
• Continuous Integration and Deployment (CI/CD): Implementing efficient CI/CD processes to support fast and reliable application deployments.

Addressing these challenges requires platform teams to make adjustments and optimizations in their tools and processes.

5 Lessons Learned Managing Kubernetes in Enterprise Organizations

Here is the translation of the blog post from Fairwinds titled “5 Lessons from Managing Kubernetes in Enterprise Organizations”:

1. Automation is Key: Leveraging automation tools is crucial for simplifying cluster management and operations, reducing human errors, and increasing efficiency.
2. Centralized Management and Standardization: Establishing consistent management standards and processes is important to ensure uniformity in cluster configurations and operations.
3. Focus on Security: Implementing strict security policies, including access controls, vulnerability scanning, and compliance checks, is essential.
4. Monitoring and Observability: Setting up effective monitoring and logging systems helps in timely detection and resolution of issues.
5. Continuous Learning and Adaptation: In a rapidly evolving technology landscape, ongoing learning and adaptation to new tools and methods are necessary.

These lessons aim to guide enterprises in better managing and optimizing their Kubernetes environments.

Monitoring with OpenTelemetry and Elastic APM in Kubernetes

Here’s a summary of the Medium article titled “Monitoring with OpenTelemetry and Elastic APM in Kubernetes”:

1. Introduction to OpenTelemetry: The article introduces OpenTelemetry, focusing on its role in collecting metrics, logs, and traces from distributed systems.
2. Overview of Elastic APM: It explains the functionality of Elastic APM and how it integrates with OpenTelemetry for performance monitoring and application tracing.
3. Integration Steps: The article provides a step-by-step guide on integrating OpenTelemetry with Elastic APM, covering configuration, data collection, and visualization.
4. Best Practices: It includes best practices for optimizing monitoring setups, such as setting appropriate tracing contexts and adjusting data sampling rates.
5. Challenges and Solutions: It addresses potential challenges in the implementation process and offers solutions to overcome them.

These insights aim to help organizations implement effective monitoring and performance analysis within their Kubernetes environments.

OpenTofu Registry Gets a User Interface — and an API

The Linux Foundation’s open source Infrastructure as Code (IaC) tool has gotten a visual interface for its component registry, courtesy of IaC platform provider Spacelift and other volunteers.

OpenTofu has also established an Application Programming Interface (API — now in Beta), for programmatic access to the registry, which is hosted, gratis, by Cloudflare.

For many users of OpenTofu — and HashiCorp Terraform from which it was forked — learn about the capabilities of IaC directly through reading the documentation found in a registry.

Kuadrant Accepted as Cloud Native Computing Foundation (CNCF) Sandbox Project

As of June 2024, Kuadrant has been accepted as a sandbox project in the CNCF.

Kuadrant is a set of Kubernetes-native controllers, services and APIs that provide gateway policies for existing Gateway API providers on both single and multi-cluster environments. It builds on top of Kubernetes Gateway API and technologies such as Istio and Envoy to introduce provider-agnostic Gateway Policies for Kubernetes.

The project provides the ability to connect ingress gateways upwards with Cloud DNS and Load Balancing providers, to set policies inwards with TLS and advanced (L7) service protection such as Auth and Rate limiting and to propagate desired gateway configurations downwards across multi-cluster environments.
