Best Package Managers for Docker

fpm is a tool that lets you easily create packages for Debian, Ubuntu, Fedora, CentOS, RHEL, Arch Linux, FreeBSD, macOS, and more! fpm isn’t a new packaging system, it’s a tool to help you make packages for existing systems with less effort. It does this by offering a command-line interface to allow you to create packages easily. FPM is written in ruby and can be installed using gem. For some package formats (like rpm and snap), you will need certain packages installed to build them. Some package formats require other tools to be installed on your machine to be built; especially if you are building a package for another operating system/distribution. FPM takes your program and builds packages that can be installed easily on various operating systems. It can take any nodejs package, ruby gem, or even a python package and turn it into a deb, rpm, pacman, etc. package.

Artifact Registry is Google Cloud’s unified, fully managed package and container registry designed for high-performance artifact storage and dependency management. It centralizes host­ing of container images (Docker/OCI), Helm charts, language packages (Java/Maven, Node.js/npm, Python), and OS packages, offering fast, scalable, reliable, and secure handling with built-in vulnerability scanning and IAM-based access control. Integrated seamlessly with Google Cloud CI/CD tools like Cloud Build, Cloud Run, GKE, Compute Engine, and App Engine, it supports regional and virtual repositories with granular security via VPC Service Controls and customer-managed encryption keys. Developers benefit from standardized Docker Registry API support, comprehensive REST/RPC interfaces, and migration paths from Container Registry. Daily updated documentation includes quickstarts, repository management, access configuration, observability tools, and deep-dive guides.
