Docker Container Image Security: 13 Best Practices
🛡️ Docker container images in production are a prime target for attackers. This video covers 13 actionable best practices to reduce your attack surface and detect malicious activity faster. You'll learn how to build lean, immutable, and deterministic images using multi-stage builds, distroless bases, and non-root users. We explore SBOM generation with Syft, provenance attestation with Cosign, CVE scanning workflows, and secret management strategies. From choosing LTS base images like Alpaquita Linux to implementing host hardening, these practices will help you ship secure containers confidently. Perfect for Java developers, DevOps engineers, and architects building production-grade infrastructure.
