Rootless Podman lets you run containers without a privileged daemon, reducing attack surface and eliminating sudo. Follow a short workflow to verify and use rootless containers safely.
Learn how to integrate Trivy with Harbor to automate container vulnerability scanning, block critical CVEs, and secure your CI/CD pipeline.
Learn how Docker multi‑stage builds let you compile with heavy tools and ship only the needed binary, cutting image size by 70‑90 % and improving container security.
Production Docker images often carry compilers and source code they never use. Multi-stage builds separate build-time tools from runtime artifacts, shrinking images and reducing attack surface—if you choose the right base and verify the result.
Production containers often ship compilers and source code they never use. Multi-stage Docker builds let you compile in one stage and copy only the final binary into a minimal runtime image, cutting size and attack surface.
Decide whether to activate Harbor’s Trivy scanner, compare it with Clair and Anchore, and follow a concrete workflow to install, enable, and validate scans.
Podman rootless mode lets you run daemon-less containers as a normal user with user namespaces and systemd integration, but it limits host device and privileged port access. Learn how to verify rootless operation and make services persistent.
An architecture note on Podman's rootless mode: what it requires, the minimal design, trust boundaries, operational checks, failure modes, and when to redesign.
Learn how to use Docker multi-stage builds to separate build-time toolchains from minimal runtime images, reducing image size and eliminating security risks from build-time secrets.
