run nexus docker image

docker run -d -p 8081:8081 --name nexus sonatype/nexus3

• To run, binding the exposed port 8081 to the host, use:

docker run -d -p 8081:8081 --name nexus sonatype/nexus3

• pass jvm arguments

docker run -d -p 8081:8081 --name nexus -e INSTALL4J_ADD_VM_PARAMS="-Xms2703m -Xmx2703m -XX:MaxDirectMemorySize=2703m -Djava.util.prefs.userRoot=/some-other-dir" sonatype/nexus3

• When stopping, be sure to allow sufficient time for the databases to fully shut down.

docker stop --time=120 <CONTAINER_NAME>

• To test:
  curl http://localhost:8081/
