Publish to

You’ll need an account on

After creating an account, obtain an API key from By default, RubyGems uses the file ~/.gem/credentials to store your API key. These credentials will be used to publish the gem. Replace username and password with the credentials you created at

curl -u username:password > ~/.gem/credentials
chmod 0600 ~/.gem/credentials

Before proceeding, make sure you have the right version in your gemspec file and commit your changes.

  • s.version = '0.1.0'

To publish version 0.1.0 of your new logstash gem:

bundle install
bundle exec rake vendor
bundle exec rspec
bundle exec rake publish_gem

Execute rake publish_gem:

  1. Reads the version from the gemspec file (s.version = '0.1.0')
  2. Checks in your local repository if a tag exists for that version. If the tag already exists, it aborts the process. Otherwise, it creates a new version tag in your local repository.
  3. Builds the gem
  4. Publishes the gem to

That’s it! Your plugin is published! Logstash users can now install your plugin by running:

bin/plugin install logstash-output-mypluginname

Where <plugintype> is input, output, filter, or codec, and <mypluginname> is the name of your new plugin.
