Docker Security: Securing Containers and Swarm Clusters

Container security is critical to modern application deployment, yet default configurations often leave systems vulnerable to exploits. This text-based course guides you through securing Docker engines, container filesystems, and multi-node Swarm clusters from the ground up. What you'll learn: - Understand core container security principles and how to isolate workloads safely - Configure Docker Swarm clusters with cryptographic node identities and mutual TLS - Implement encrypted overlay networks to protect communication between services - Manage sensitive data securely using built-in secrets without exposing them in images - Scan container images for vulnerabilities using modern security analysis tools - Apply rootless execution and resource limits to prevent container breakout exploits You will start with fundamental security concepts and container isolation basics before moving into practical cluster orchestration, network encryption, and vulnerability management through clear, step-by-step written explanations. This course is designed for developers, system administrators, and DevOps beginners who want to build secure container pipelines, with no prior security experience required.
