This is a plugin for Logstash.
It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.
This Kafka Output Plugin is now a part of the Kafka Integration Plugin. This project remains open for backports of fixes from that project to the 8.x series where possible, but issues should first be filed on the integration plugin.
Logstash provides infrastructure to automatically generate documentation for this plugin. We use the asciidoc format to write documentation so any comments in the source code will be first converted into asciidoc and then into html. All plugin documentation are placed under one central location.
- For formatting code or config example, you can use the asciidoc
[source,ruby]
directive - For more asciidoc formatting tips, see the excellent reference here https://github.com/elastic/docs#asciidoc-guide

-
To get started, you'll need JRuby with the Bundler gem installed.
-
Create a new plugin or clone and existing from the GitHub logstash-plugins organization. We also provide example plugins.
-
Install dependencies
bundle install
- Update your dependencies
bundle install
- Run unit tests
bundle exec rspec
- Run integration tests
you'll need to have docker available within your test environment before
running the integration tests. The tests depend on a specific Kafka image
found in Docker Hub called spotify/kafka
. You will need internet connectivity
to pull in this image if it does not already exist locally.
bundle exec rspec --tag integration
- Edit Logstash
Gemfile
and add the local plugin path, for example:
gem "logstash-output-kafka", :path => "/your/local/logstash-output-kafka"
- Install plugin
# Logstash 2.3 and higher
bin/logstash-plugin install --no-verify
# Prior to Logstash 2.3
bin/plugin install --no-verify
- Run Logstash with your plugin
bin/logstash -e 'output { kafka { topic_id => "kafka_topic" }}'
At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.
You can use the same 2.1 method to run your plugin in an installed Logstash by editing its Gemfile
and pointing the :path
to your local plugin development directory or you can build the gem and install it using:
- Build your plugin gem
gem build logstash-output-kafka.gemspec
- Install the plugin from the Logstash home
bin/plugin install /your/local/plugin/logstash-output-kafka.gem
- Start Logstash and proceed to test the plugin
All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.
Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.
It is more important to the community that you are able to contribute.
For more information about contributing, see the CONTRIBUTING file.
