GKE-Linkerd2

This repository contains scripts that I used to test Linkerd2 on my GKE cluster.

Getting Started

Provision a GCP custom VPC in 4 regions (us-west1, us-west2, us-east1, us-east2) and a GKE cluster:

$ make infra

Create managed DNS zone:

$ DNS_DOMAIN=<dns_domain> make infra/managed-zones

Deploy ExternalDNS:

$ PROVIDER=google make external-dns

Install linkerd CLI:

$ make linkerd-cli

Install linkerd:

$ make linkerd

Deploy applications:

$ make apps/nginx
$ make apps/cockroachdb
$ make apps/emojivoto
$ make apps/redis
$ make apps/guestbook
$ make apps/stars

Repository Layout

The infra folder contains a set of bash scripts for creating the custom VPC, subnets, firewall rules and GKE cluster.

The apps folder contains the following applications used for testing the cluster:

• nginx (src) - 3-replica deployment with a load balancer service and network policies
• cockroachdb - 3-replica statefulset with dynamic storage provisioning
• emojivoto (src) - an emoji votes web application with an ingress frontend
• guestbook + redis (src) - the guestbook application from the EKS Getting Started docs
• stars (src) - the Calico stars policy demo

Clean Up

Delete applications:

$ make apps/nginx-delete
$ make apps/cockroachdb-delete
$ make apps/emojivoto-delete
$ make apps/redis-delete
$ make apps/guestbook-delete
$ make apps/stars-delete
