This project has been split into two and moved for better management and maintenance.
The RHEL and Red Hat CentOS images are now housed in our official Docker GitHub project, available at sonatype/docker-nexus3. Information on how the RHEL and Red Hat CentOS images differ from the default offering is described in Red Hat Certified Image.
The OpenShift Templates have been moved to a dedicated GitHub repository for deployment reference architecture, available at sonatype-nexus-community/deployment-reference-architecture.
As the contents from this repository are now housed elsewhere, this repository is considered volatile and may be removed at any time. It will be kept up temporarily to provide guidance to the new location(s) and any reference required to sunsetted files. The old readme is available at README.old.md.
