Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Attributes

The following attributes are set under the nexus namespace:

  • version - sets the version to install
  • user - sets the user to install nexus under
  • group - sets the group to install nexus under
  • url - sets the URL where the nexus package is located
  • port - the port to run nexus on
  • host - the hostname to use for nexus
  • context_path - the user home directory
  • name - the name of the Nexus
  • bundle_name - the name of the internal folder of the Nexus tar. Usually nexus-{professional or nothing}-{VERSION}
  • home - the installation directory for nexus. Uses name.
  • current_path - the above home/current/bundle_name. The artifact_deploy resource uses the current symlink to denote the currently installed version.
  • pid_dir - the pid directory defined in the nexus.erb template. Saves a pid in the pids directory created by the artifact_deploy resource.
  • conf_dir - the above home/conf
  • bin_dir - the above home/bin
  • work_dir - the above path/sonatype-work/nexus
  • plugins - an Array of Nexus plugins that will be installed by the default recipe.

The following attribute is set under the nexus::jetty namespace:

  • loopback - if true, the jetty.xml.erb will be written to disable access to anything but localhost. Useful for enabling access to Nexus via Jetty's HTTP connection.

The following attributes are set under the nexus::ssl namespace and are related to the SSL settings of Nexus:

  • verify - if true, the calls in the chef_nexus.rb library will verify SSL connections. This is useful to disable when working with a self-signed certificate.
  • ssl_certificate::key - the key to look for in the nexus::ssl_certificate encrypted data bag.

The following attributes are set under nexus::nginx namespace:

  • listen_port - the port to listen on for nginx.
  • server_name - the name of the nginx server.
  • server::options - used to generate options in the server section of the nginx conf file.
  • proxy::options - used to generate proxy options in the location section of the nginx conf file.

The following attributes are set under the nexus::cli namespace:

  • url - The url that the nexus_cli gem will connect to. The default recipe uses this to configure itself, so localhost.
  • repository - The repository that nexus_cli gem will use for push / pull operations. A requirement of nexus_cli, not used by this cookbook.
  • packages - required packages to install for using the chef_gem "nexus_cli"

The following attributes are set under the nexus::repository namespace:

  • create_hosted - An Array of repository names that will be used to create Hosted Repositories.
  • create_proxy - A Hash of repository names to urls that will be used to create Proxy Repositories.
  • publishers - An Array of repository names that will be set to publish artifacts (Smart Proxy).
  • subscribers - An Array of repository names that will be set to subscribe to artifacts (Smart Proxy).

The following attributes are set under the nexus::smart_proxy namespace:

  • enable - true if we want to enable Smart Proxy, false if not.
  • host - The host to use for Smart Proxy configuration.
  • port - The port to use for Smart Proxy configuration.

The following attributes are not fully supported but are under the nexus::mount namespace:

  • nfs::enable - enables an NFS mount.
  • nfs::mount_point - the local path to mount an NFS drive to.
  • nfs::device_path - the remote server where the NFS drive is located.
  • nfs::non_mount_dir - Sonatype does not recommend using NFS with Nexus, because of Solr searchs on particular directories of the Nexus installation.

SSL

The files directory contains a self-signed certificate and key that are installed to nginx::dir/shared/certificates/nexus-proxy.crt and nginx::dir/shared/certificates/nexus-proxy.key.

By default, the cookbook will look for a ssl_certificate encrypted data bag:

knife data bag create nexus ssl_certificate -c <your chef config> --secret-file=<your secret file>

Your data bag should look like the following:

{ "id": "ssl_certificate", "fully-qualified-domain-name": { "crt": "base64-encoded-ssl-certificate", "key": "base64-encoded-private-key" }, ... }

The cookbook will look for an entry for your node[:fqdn] in the data bag, and if found, will get the certificate and key, base64 decode them, and write them using the file resource. If there is no entry in the data bag, the default action will use the cookbook_file resource to copy the self-signed certificate and key and install them.

Nexus Usage

Many of the LWRPs utilize the Nexus CLI gem to interact with the Nexus server. In order to use them, you must first create an encrypted data bag that contains the credentials for your Nexus server.

knife data bag create nexus credentials -c <your chef config> --secret-file=<your secret file>

Your data bag should look like the following:

{ "id": "credentials", "default_admin": { "username": "admin", "password": "admin123" }, "updated_admin": { "username": "admin", "password": "customize_me" } }

Out-of-the-box, Nexus comes configured with a specific administrative username/password combo. The default recipe change the password for that account to the password configured in the updated_admin element.

Smart Proxy Usage

When Smart Proxy is enabled (nexus::pro recipe), repositories need to be set to become publishers or subscribers. In addition, we need to store the certificates of other Nexus servers on the server that Smart Proxy is being enabled on.

knife data bag create nexus certificates -c <your chef config> --secret-file=<your secret file>

Your data bag will store a certificate and description based on the IP address of other Nexus servers and should look like the following:

{ "id": "certificates", "192.168.0.1": { "certificate": "-----BEGIN CERTIFICATE-----\n...\n-----END CERTIFICATE-----\n", "description": "192.168.0.1 Trusted Key" }, "192.168.0.2": { "certificate": "-----BEGIN CERTIFICATE-----\n...\n-----END CERTIFICATE-----\n", "description": "192.168.0.2 Trusted Key" } }

Override the nexus::repository attributes to set these appropriately for your Nexus.

Usage

Simply add the "nexus::default" recipe to the node where you want Sonatype Nexus installed.

To install Nexus Pro and perform some extra steps, use the "nexus::pro" recipe. Most likely, all you'll need is to override the following attributes like so:

:nexus => {
  :version => '2.1.2',
  :checksum => 'new checksum',
  :url => 'some/url/to/nexus-professional-2.1.2-bundle.tar.gz',
}
