Why use Bitnami Container Images?
Bitnami container images are always up-to-date, secure, and built to work right out of the box.
Bitnami packages applications following industry standards, and continuously monitors all components and libraries for vulnerabilities and application updates. When any security threat or update is identified, Bitnami automatically repackages the applications and pushes the latest versions to the cloud marketplaces.
