Recipes

default

Downloads and installs the latest Nexus 3 Repository Manager OSS.

Attributes

• node['nexus3']['url'] - The download URL of Nexus 3 Repository Manager. This can be a specific version of Nexus Repository Manager OSS or Nexus Repository Manager Pro. Default http://download.sonatype.com/nexus/3/latest-unix.tar.gz.
• node['nexus3']['checksum'] (optional) - The checksum of Nexus Repository Manager. Default nil.
• node['nexus3']['path'] - Install directory. Default Linux: /opt Windows: #{ENV['SYSTEMDRIVE']}.
• node['nexus3']['data'] - Data directory. Default #{node['nexus3']['path']}/sonatype-work/nexus3.
• node['nexus3']['home'] - Link to install directory. Default #{node['nexus3']['path']}/nexus3.
• node['nexus3']['properties_cookbook'] - Cookbook that contains the template to use. Default nexus3.
• node['nexus3']['properties_source'] - Template file that will be used to create the #{data}/etc/nexus.properties file. Default nexus.properties.erb.
• node['nexus3']['properties_variables'] - A Hash of variables that are passed into a template file. Default { host: '0.0.0.0', port: '8081', args: '${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-requestlog.xml', context_path: '/' }.
• node['nexus3']['vmoptions_cookbook'] - Cookbook that contains the template to use. Default nexus3.
• node['nexus3']['vmoptions_source'] - Template file that will be used to create the #{home}/bin/nexus.vmoptions file. Default nexus.vmoptions.erb.

Examples

Changing the HTTP Port and/or Context Path

The default value for the HTTP port used to access the repository manager user interface and resources is 8081. To change HTTP Port to 8443, Context Path to /components/ and serve HTTPS directly set the properties_variables hash with the updated settings:

include_recipe 'java_se'

node.default['nexus3']['properties_variables'] = { port: '8443', args: '${jetty.etc}/jetty.xml,${jetty.etc}/jetty-https.xml,${jetty.etc}/jetty-requestlog.xml', context_path: '/components/' }
include_recipe 'nexus3'

Updating Memory Allocation and other JVM Paramaters

The default and maximum heap sizes for the repository manager are a value of 1200M, suitable for most usage patterns. To install latest nexus3 with 1500M initial memory and 2G max memory, set it in the vmoptions_variables:

include_recipe 'java_se'

node.default['nexus3']['vmoptions_variables'] = { Xms: '1500M', Xmx: '2G' }
include_recipe 'nexus3'
