Short Description
This docker set-up SSL for nexus3 and expose port 8081, 5000 & 5001
Full Description

sonatype/nexus3

A Dockerfile for Sonatype Nexus Repository Manager 3, based on CentOS.

To run, binding the exposed port 8081 to the host.

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

To test:

$ curl -u admin:admin123 http://localhost:8081/service/metrics/ping

To (re)build the image:

Copy the Dockerfile and do the build-

$ docker build --rm=true --tag=sonatype/nexus3 .

Notes

  • Default credentials are: admin / admin123

  • It can take some time (2-3 minutes) for the service to launch in a
    new container. You can tail the log to determine once Nexus is ready:

$ docker logs -f nexus
  • Installation of Nexus is to /opt/sonatype/nexus.

  • A persistent directory, /nexus-data, is used for configuration,
    logs, and storage. This directory needs to be writable by the Nexus
    process, which runs as UID 200.

  • Three environment variables can be used to control the JVM arguments

    • JAVA_MAX_MEM, passed as -Xmx. Defaults to 1200m.

    • JAVA_MIN_MEM, passed as -Xms. Defaults to 1200m.

    • EXTRA_JAVA_OPTS. Additional options can be passed to the JVM via
      this variable.

    These can be used supplied at runtime to control the JVM:

    $ docker run -d -p 8081:8081 --name nexus -e JAVA_MAX_HEAP=768m sonatype/nexus3
    

Persistent Data

There are two general approaches to handling persistent storage requirements
with Docker. See Managing Data in Containers
for additional information.

  1. Use a data volume container. Since data volumes are persistent
    until no containers use them, a container can created specifically for
    this purpose. This is the recommended approach.

    $ docker run -d --name nexus-data sonatype/nexus3 echo "data-only container for Nexus"
    $ docker run -d -p 8081:8081 --name nexus --volumes-from nexus-data sonatype/nexus3
    
  2. Mount a host directory as the volume. This is not portable, as it
    relies on the directory existing with correct permissions on the host.
    However it can be useful in certain situations where this volume needs
    to be assigned to certain specific underlying storage.

    $ mkdir /some/dir/nexus-data && chown -R 200 /some/dir/nexus-data
    $ docker run -d -p 8081:8081 --name nexus -v /some/dir/nexus-data:/nexus-data sonatype/nexus3
