How to Secure Your Node.js Containers on Kubernetes With Best Practices

Discover essential security best practices for deploying Node.js containers on Kubernetes in this informative conference talk from DevOps.js Conference 2022. Learn how to secure your cluster, implement OIDC for access control, and protect your Node.js applications running on Kubernetes. Explore topics such as RBAC implementation, OpenID Connect usage, secrets management, and keeping Kubernetes versions up-to-date. Gain insights on restricting access to critical components, controlling inter-pod traffic, utilizing namespaces for workload isolation, and implementing resource limits. Delve into infrastructure best practices, including running containers with non-root privileges, using minimal up-to-date official base images, preventing unwanted kernel module loading, and enabling container image scanning in CI/CD pipelines. Master the art of auditing images, leveraging pod security policies, and addressing Node.js-specific security concerns to enhance the overall security posture of your Kubernetes environment.
