kind

KinD (Kubernetes in Docker) with extra tools for development environments.

- Attention:

Despite the name, the developers of this project did not create the kind tool. We just automate the creation of a Kubernetes cluster using kind and deploy some useful services to the development/test environment.

Hardware requirements

A cluster with 2 nodes requires (not counting the amount of hardware resources needed to run the applications you intend to deploy on the cluster).

• CPU: 1vCPU with 2 GHz
• Memory: 2 GB
• HD: 20 GB

OS Supported

Tested with the following Operating Systems (OS):

• Red Hat/Centos/Fedora
• Debian/Ubuntu

Features

• Calico CNI
• OpenEBS for Dynamic Volume Provisioning
• MetalLB for LoadBalancing
• Ingress NGINX with default backend
• Linkerd for Service Discovery and service mesh with dashboard
• Istio for Service Discovery and service mesh with dashboard
• Example pod with installed ingress entrypoint

Dependencies

Install dependecies following the instructions on the REQUIREMENTS.md file.

• jq - Command line JSON processor
• openssl - Command line SSL/TLS tool
• kubectl
• docker
• kind
• helm
• linkerd
• istio

Creating your kind clusters

Create a kind cluster using the following commands:

Linkerd for Service Discovery and Service Mesh

chmod +x createCluster.sh
./createCluster.sh

Istio for Service Discovery and Service Mesh

chmod +x ./istio/createClusterWithIstio.sh
./istio/createClusterWithIstio.sh

Wait a few minutes (about 10 to 15 minutes) while the cluster is being created and services are being deployed.

Access Application (Linkerd)

Get the addresses of the applications to be accessed in the browser:

kubectl get ingress -A

Linkerd default username and password:

user: admin
password: admin

Access Application (Istio)

If using'createClusterWithIstio.sh ' to access the application, just through the IP provided by metallb.

To get the addresses of the applications, just find the IP:

kubectl get services --namespace istio-system istio-ingressgateway --output jsonpath='{.status.loadBalancer.ingress[0].ip}'

Ex: curl http://172.18.0.130/productpage

Cleanup / Uninstall

Checking your created clusters

Get the list of clusters created with kind:

kind get clusters

Deleting your created clusters

Remove a kind cluster:

kind delete clusters <clusterName>

Remove all clusters created with kind:

kind delete clusters $(kind get clusters)
