Private Gem Repositories

The Logstash plugin manager connects to a Ruby gems repository to install and update Logstash plugins. By default, this repository is http://rubygems.org.

Some use cases are unable to use the default repository, as in the following examples:

A firewall blocks access to the default repository.
You are developing your own plugins locally.
Airgap requirements on the local system.

When you use a custom gem repository, be sure to make plugin dependencies available.

Several open source projects enable you to run your own plugin server, among them:

Editing the Gemfile

edit

The gemfile is a configuration file that specifies information required for plugin management. Each gem file has a source line that specifies a location for plugin content.

By default, the gemfile’s source line reads:

# This is a Logstash generated Gemfile.
# If you modify this file manually all comments and formatting will be lost.

source "https://rubygems.org"

To change the source, edit the source line to contain your preferred source, as in the following example:

# This is a Logstash generated Gemfile.
# If you modify this file manually all comments and formatting will be lost.

source "https://my.private.repository"

After saving the new version of the gemfile, use plugin management commands normally.
