Running

To run with ports 8070 (web UI) and 8071 (admin port) use:

docker run -d -p 8070:8070 -p 8071:8071 --name nexus-iq-server sonatype/nexus-iq-server

or to let docker assign available ports use:

docker run -d -p 8070 -p 8071 --name nexus-iq-server sonatype/nexus-iq-server

To get the assigned port or check if the server is running use:

docker ps --filter "name=nexus-iq-server"

Building the Nexus IQ Server image

To build a docker image from the Dockerfile you can use this command:

docker build --rm=true --tag=sonatype/nexus-iq-server .

The following optional variables can be used when building the image:

IQ_SERVER_VERSION: Version of Nexus IQ Server
IQ_SERVER_SHA256: Check hash matches the downloaded IQ Server archive or else fail build. Required if IQ_SERVER_VERSION is provided.
JAVA_URL: Download URL for Oracle JDK
JAVA_SHA256: Check hash matches the downloaded JDK or else fail build. Required if JAVA_URL is provided.
SONATYPE_WORK: Path to Nexus IQ Server working directory where variable data is stored

Chef Solo for Runtime and Application

Chef Solo is used to build out the runtime and application layers of the Docker image. The Chef cookbook being used is available on GitHub at sonatype/chef-nexus-iq-server.

Testing the Dockerfile

We are using rspec as test framework. serverspec provides a docker backend (see the method set in the test code) to run the tests inside the docker container, and abstracts away the difference between distributions in the tests (e.g. yum, apt,...).

rspec [--backtrace] spec/Dockerfile_spec.rb

Notes

Default credentials are: admin / admin123
Installation of Nexus IQ Server is to /opt/sonatype/nexus-iq-server.
There is an environment variable that is being used to pass JVM arguments to the startup script
- JAVA_OPTS, passed to the startup script. Defaults to -Djava.util.prefs.userRoot=${SONATYPE_WORK}/javaprefs.
This can be adjusted at runtime:
```
$ docker run -d -p 8070:8070 -p 8071:8071 --name nexus-iq-server -e JAVA_OPTS="-Djava.util.prefs.userRoot=/some-other-dir" sonatype/nexus-iq-server
```
Of particular note, -Djava.util.prefs.userRoot=/some-other-dir can be set to a persistent path, which will maintain the installed Nexus IQ Server License if the container is restarted.

Persistent Data

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

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

$ docker volume create --name sonatype-work
$ docker run -d -p 8070:8070 -p 8071:8071 --name nexus-iq-server -v sonatype-work:/sonatype-work sonatype/nexus-iq-server

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/sonatype-work
$ docker run -d -p 8070:8070 -p 8071:8071 --name nexus-iq-server -v /some/dir/sonatype-work:/sonatype-work sonatype/nexus-iq-server

Configuration

The solo.json.erb template file can be used to customize the Nexus IQ Server configuration. The nexus_iq_server.config property of this Embedded Ruby template will be rendered and then saved as the Nexus IQ Server's config.yml. See IQ Server Configuration for more details as to what values are supported.

Here is an example of how to set the proxy section of config.yml:

  :nexus_iq_server => {
    :version => ENV['IQ_SERVER_VERSION'],
    :checksum => ENV['IQ_SERVER_SHA256'],
    :install_dir => ENV['IQ_HOME'],
    :config => {
      :sonatypeWork => ENV['SONATYPE_WORK'],
      :proxy => {
        :hostname => '127.0.0.1',
        :port => 80,
        :username => 'anonymous',
        :password => 'guest'
      }
    }
  }
