Implementing the Sidecar pattern using a service mesh like Istio involves several steps.
Download the latest Istio version using the below curl command: curl -L https://istio.io/downloadIstio | sh - Add istioctl to your path: export PATH="$PATH:/path-to-istio/bin" Install Istio on the cluster: istioctl install --set profile=demo -y For Istio to automatically inject sidecars, enable sidecar injection in your Kubernetes namespace: kubectl label namespace <your-namespace> istio-injection=enabled
Create a basic Node.js application as the primary microservice. Then, create Dockerfiles for both the main application and the sidecar. Finally, create Kubernetes deployment and service manifests to define the configurations.
