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.

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

Tested with the following Operating Systems (OS):

• Red Hat/Centos/Fedora
• Debian/Ubuntu

• 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

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

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.

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

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 https://172.18.0.130/productpage

Get the list of clusters created with kind:

kind get clusters

Remove a kind cluster:

kind delete clusters <clusterName>

Remove all clusters created with kind:

kind delete clusters $(kind get clusters)
