Learn to deploy Zitadel, a modern identity and access management platform, to Kubernetes clusters using official Helm charts in this comprehensive 16-minute hands-on tutorial. Master the complete deployment process starting with essential prerequisites including setting up Kubernetes clusters (kind, minikube, or cloud-based), installing kubectl and Helm, and exploring the official zitadel/zitadel-charts repository. Configure PostgreSQL databases following best practices by setting up your own PostgreSQL instance rather than relying on Helm dependencies, implement CloudNativePG for effective database clustering, and manage database credentials securely using environment variables and Kubernetes secrets. Execute the core installation by adding the Zitadel Helm repository, configuring deployment values files, setting up critical security configurations including master key management, and running Helm installation commands while troubleshooting common deployment issues. Access and validate your deployment through external domain configuration for local development, port forwarding setup to reach the Zitadel console, initial admin login configuration, and kubectl validation commands. Implement advanced production configurations including enhanced security through Kubernetes secret integration, secure master key generation and storage, non-root container execution contexts, multi-replica high availability setups, pod disruption budgets for zero-downtime maintenance, and proper resource management for CPU, memory, and storage. Configure production infrastructure elements such as ingress controllers for external access, TLS and DNS management, monitoring integration with Prometheus and service monitors, and deployment of complementary services including secrets, service mesh configurations, and OpenTelemetry collectors. Establish day-two operations covering monitoring and observability setup, update and upgrade strategies, backup and disaster recovery planning, and performance tuning optimization to achieve a fully functional, production-ready Zitadel deployment with secure PostgreSQL integration, proper secret management, high availability configuration, monitoring capabilities, production-grade security settings, and external access configuration.
