gke-toolbox: A Smarty repository from viglesiasce

Introduction

The GKE Toolbox is a Helm chart that installs and configures useful tools into your Container Engine Clusters

Tools

Enabled by Default

Prometheus (chart) -> Kubernetes native monitoring and alerting of your nodes, pods, services, and controller states
Grafana (chart) -> Flexible Dashboards for Kubernetes
Nginx Ingress (chart) -> Allows you to use Nginx as an ingress controller which can be more flexible than the Google HTTP(S) load balancer

Disabled by Default

Kube Lego (chart) -> Automatically get TLS certificates for your ingresses
External DNS -> Map your service and ingress IPs to DNS records in Cloud DNS
Istio (chart) -> Kubernetes native service mesh
Spinnaker (chart) -> Continuous Delivery solution for Kubernetes workloads
Gitlab (chart) -> Source code management and continuous integration/delivery system

Prerequisites

Credentials to a Container Engine cluster with at least 3 cores and 8GB or RAM
For external-dns, a cluster with the following scope enabled at creation: https://www.googleapis.com/auth/ndev.clouddns.readwrite
For Istio tracing to work you must have the following scope enabled: https://www.googleapis.com/auth/trace.append

For example:

$ gcloud container clusters create tb-test --scopes https://www.googleapis.com/auth/ndev.clouddns.readwrite,https://www.
googleapis.com/auth/trace.append
