5 Best Security Practices for your Production-Ready Containers
summary
Slim.AI analyzes hundreds of container images (billions of pulls) and demonstrates with a Python Flask app built on four bases that careful choices and postprocessing matter: the Debian-based python image shows 82 vulnerabilities (1 critical, 11 high) while a Ubuntu 22.04 build shows zero critical/high and only three medium; base sizes range from ~60 MB (Alpine) to ~159 MB (Debian python) before slimming and drop to ~19–25 MB after optimization. Docker Slim / Slim.AI minifies images into single-layer artifacts, typically cutting size 3–7× here (10–30× often) and removing unused packages and CVEs; recommended steps: pin bases, run unprivileged users, avoid apt recommended installs, rebuild with --pull --no-cache, and include SBOM/vulnerability scans (trivy/snyk/grype/clair).
