I operate some Docker services. Some of them are selfmade with Dockerfiles. I now want to store them into a Sonatype Nexus private repository to publish them to another server in my network.
My research half a year ago gave me Nexus 2 OSS as best option. But now Nexus 3 got released and I'm kinda confused. What version should I use? Greatest confusion is because there is no difference between Pro and OSS version anymore on Docker Hub:
oss and pro
3.x.x
Question is: May I use Nexus 3 for free? Or will there be any costs as in Nexus 2 Pro?

Yes it supports this.
Nexus Repository OSS is an open source repository that supports many artifact formats, including Docker, Java™, and npm. With the Nexus tool integration, pipelines in your toolchain can publish and retrieve versioned apps and their dependencies by using central repositories that are accessible from other environments.
Nexus Repository Manager provides for three different kinds of repositories: Proxy repositories, Hosted repositories and Virtual repositories.
Nexus Repository Manager 2 does not support Docker as a format. Nexus Repository Manager 3 does, and Docker support is a part of our OSS solution, meaning you can use Docker completely free. There is a professional version coming with 3.1 that will start to have features such as high availability, expanded enterprise support, as well as just regular support of the product.
As for the Docker images, Nexus 3 now has the ability to operate as OSS or Pro from the same bundle so you'll likely only see tags for Releases, not OSS and Pro.
