cdks8-xray

Provides a cdk8s Construct to synthesize AWS X-Ray api-resources on Amazon EKS.

Installation and Usage

Install cdk8s-xray construct from npm or yarn:

npm install -s cdk8s-xray

Usage:

import { XRayApp, DaemonProtocol, XRayConfig } from 'cdk8s-xray'

// inside your chart:
let config: XRayConfig = {
    image: "rnzdocker1/eks-workshop-x-ray-daemon:dbada4c77e6ae10ecf5a7b1c5864aa6522d9fb02",
    ns: "default",
    daemon: {
        daemonProtocol: DaemonProtocol.UDP,
        port: 2000,
        logLevel: "prod"
    }
}

new XRayApp(this, 'prod', config);

Features:

• Adapted from the EKS Workshop X-Ray. A few cdk8s quirks make the generated manifest different though:
