Docker Containerization Best Practices for Production

Using multi-stage Dockerfiles separates build tool dependencies from final runtime containers, reducing image sizes from gigabytes down to a few megabytes for fast container deployment.

Running containers as non-root users prevents container breakout vulnerabilities from granting administrative host root access during security exploits.

Defining explicit memory and CPU constraints prevents a single container leak from crashing host nodes. Health check probes enable orchestrators to restart unhealthy containers automatically.

Integrating container vulnerability scanners into deployment pipelines blocks base images containing known CVE vulnerabilities from reaching production servers.
