Leveraging Tinkerbell to provision Kubernetes clusters on bare metal servers. This includes: - Designing and implementing Tinkerbell workflows, utilizing components such as Boots, Hegel, and Hook, to automate the provisioning process. - orchestrating the deployment of Kubernetes by creating custom hardware and workflow templates, ensuring seamless integration with Containerd for optimized container management. - Troubleshooting complex hardware and network issues, enhancing system reliability, and contributing to continuous improvement initiatives within the infrastructure.

Multi-cluster Communication cross Multiple Cloud Providers through Service Mesh in a GitOps and IAC way. Keywords: K8S, Helm, Istio, AWS, Equinix, Azure, Terraform, Terragrunt, GitLabCI, ArgoCd Guide of work: - Use Terraform modules and Terragrunt layers to provision your EKS, AKS, and K3s Kubernetes clusters on Equinix bare metal servers. - Integrate provisioned clusters with Rancher for centralized management. - Install Istio on each of the three clusters and ensure multicluster communicationspanning multiple networks. - Configure Istio's mTLS to ensure secure communication between services in all clusters. - Create a Helm chart that defines the demo application you want to deploy. This chart includes the application deployment, services, and other necessary Kubernetes resources. - Deploy the helm chart using argocd deployed on primary cluster. - Utilize Istio for advanced traffic management. Define VirtualServices and Gateway resources to control how traffic is routed and load balanced across clusters. - Configure Istio to implement fine-grained authorization and authentication policies to secure traffic between clusters. - Visualize the mesh using Kiali and collect metrics and traces with Grafana and Jaeger. - Deploy Istio Ingress Gateway in each cluster to expose your application externally over HTTPS. - Building CI/CD pipeline containing stages, jobs and dependencies to automate the process.
