zK8s == Kubernetes + Zeus

Here we overview the core concepts needed to understand how you can build, deploy, configure K8s apps using Zeus, with a full walkthrough example of how we created an Ethereum beacon.

Hosted Docusaurus in 5 Minutes and Under $10/month

Developing Kubernetes applications is often complex and time-consuming, with a steep learning curve. However, the advent of zK8s is changing the game, allowing developers to build Kubernetes apps with pure Go code that’s functional, testable, and effortlessly turned into deployable infrastructure.

QuickNode MarketPlace users can find Load Balancing documentation in the iris programmable proxy directory

• Adaptive Load Balancer Documentation

API Endpoints

Documentation and code examples are found here API_README.md

How to use the test suite to setup your own api calls README.md

The test directory contains useful mocks and tools for interacting with the API. It also contains a useful config-sample.yaml, convert this to config.yaml and set your bearer token here, which then allows you to use the demo code to create your first api request in seconds

Overview

1. Automates translation of kubernetes yaml configurations into representative SQL models
2. Users upload these infrastructure configurations via API where they are stored in the DB
3. Users can then query the contents of these infrastructure components, deploy, mutate or destroy them on demand

Currently Supported Workload Types

1. Deployments
2. StatefulSets
3. Services
4. ConfigMaps
5. Ingresses
6. ServiceMonitors
7. Secrets

• Node Tainting Automation & Infra Provisioning (Servers & SSDs) Deployable & Scalable on Demand.

Pods Controller

1. GetPods
2. GetPodLogs
3. PortforwardReqToPods
4. DeletePods

Not every possible field type is supported, but the most common ones are, and even a decent amount of the uncommon ones. If you find a field you need isn't supported please send us an email at support@zeus.fyi

Hades Library

Hades is used to interact with Kubernetes workloads via API, and can apply saved Zeus workloads & cookbooks onto your own in house infrastructure.

Hera Client

This client uses the OpenAI API to generate code with AI. This service is available at OpenAI cost, so just pay for the token cost, otherwise it is free to use.

Cookbooks

Contains common web2 & web3 recipes for deploying applications, and managing infrastructure using zK8s or vanilla Kubernetes.

Adaptive RPC Load Balancer Benchmarks

Over several weeks on a production load monitoring Uniswap prices

When should you consider using the Adaptive RPC Load Balancer?​

TLDR:

• You need to scale your application to handle more requests than a single endpoint can handle
• You need to reduce the error rate of your application
• Especially if you are still paying for the request even if it fails
• You need to improve the reliability of your application
• You want to run multi-step procedures in a single request
