Install and Configure Kubernetes Cluster

you can use Kind, Minikube, or k3s. but here we can use Kind as kubernetes environment

Kind Kubernetes Cluster Documentation


kind

https://github.com/launathiel/kubernetes-lightweight/blob/main/kind/kind.md

Deploy MetalLB

source: https://metallb.universe.tf/installation/

kubectl edit configmap -n kube-system kube-proxy

and set

apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind: KubeProxyConfiguration
mode: "ipvs"
ipvs:
  strictARP: true #if false, set to true

Install By Manifest

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.11.0/manifests/namespace.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.11.0/manifests/metallb.yaml

Add MetalLB Configuration

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - 172.18.0.40-172.18.0.50

you can check addresses from any range on your kubernetes node IP network

for example,

kubectl get node -o wide

Here, you get 172.18.0.2. so you can use 172.18.0.40-172.18.0.50 as addresses range

For Testing,

kubectl apply -f https://raw.githubusercontent.com/adaptivenetlab/Kubernetes/main/template/deployment/deployment.yaml
kubectl apply -f https://raw.githubusercontent.com/adaptivenetlab/Kubernetes/main/template/service/loadbalancer.yaml
kubectl get svc

if you get external IP and you can access the service, it means that your metallb loadbalancer has sucessfully deployed!

Delete Testing

kubectl delete -f https://raw.githubusercontent.com/adaptivenetlab/Kubernetes/main/template/deployment/deployment.yaml
kubectl delete -f https://raw.githubusercontent.com/adaptivenetlab/Kubernetes/main/template/service/loadbalancer.yaml

Ingress Nginx

You need helm installed on your host

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

Deploy Ingress Nginx Using Helm Chart

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
kubectl create ns ingress-nginx
helm install myingress ingress-nginx/ingress-nginx -n ingress-nginx
helm list -n ingress-nginx
kubectl get all -n igress-nginx

Check Ingress IP address

note that External-IP

Install Istio

Download Istio file

curl -L https://istio.io/downloadIstio | sh -
cd istio-1.9.2
export PATH=$PWD/bin:$PATH

Install the Istio Operator

istioctl operator init  
kubectl get all -n istio-operator

Apply istio

kubectl create ns istio-system
kubectl apply -f - <<EOF
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
metadata:
  namespace: istio-system
  name: example-istiocontrolplane
spec:
  profile: demo
EOF

Check if Istio has sucessfully installed

kubectl get all -n istio-system

Namespace Label for Service Mesh

Create postsapp Namespace

kubectl create ns postsapp

Create istio injection label

kubectl label ns postsapp istio-injection=enabled

Microservice Deployment

kubectl apply -f MongoDB/MongoDB-comments/mongodb-clusterip.yaml -n postsapp

Microservices

kubectl apply -f infra/k8s/posts-depl.yaml -n postsapp
kubectl apply -f infra/k8s/comments-depl.yaml -n postsapp
kubectl apply -f infra/k8s/client-depl.yaml -n postsapp

Configure Ingress Rule

kubectl apply -f ingress-srv.yaml -n postsapp

Add Ingress IP to /etc/hosts On VM

sudo vi /etc/hosts

172.18.0.43 posts.com

Access from Tunnel Proxy

ssh -ND 9090 user@192.168.0.20 using socks5://127.0.0.1:9090

Access From Browser

chrome.exe --proxy-server="socks5://localhost:9090"

and check on chrome, posts.com/posts

Istio Monitoring

Install Prometheus

kubectl apply -f https://gitlab.com/gilangvperdana/microservices-app-on-k-8-s-with-istio/-/raw/master/addons/prometheus.yaml -n istio-system

Install Grafana (Optional)

kubectl apply -f https://gitlab.com/gilangvperdana/microservices-app-on-k-8-s-with-istio/-/raw/master/addons/grafana.yaml -n istio-system

Change Service Grafana to LoadBalancer:

kubectl edit svc grafana -n istio-system

access http://<ip-external-service-grafana>:3000

Install Kiali

kubectl apply -f https://gitlab.com/adaptivenetlab/adaptive-network-laboratory-kubernetes-service-mesh-untuk-aplikasi-microservices/-/raw/master/addons/kiali-crd.yaml -n istio-system

kubectl apply -f https://gitlab.com/adaptivenetlab/adaptive-network-laboratory-kubernetes-service-mesh-untuk-aplikasi-microservices/-/raw/master/addons/kiali.yaml -n istio-system

Change service to LoadBalancer:

kubectl edit svc kiali -n istio-system
kubectl get svc kiali -n istio-system

access http://ip_external_kiali:20001
