Contributing to Loki Logstash Output Plugin
For information about how to use this plugin see this documentation.
Install dependencies
First, make sure you have JDK version 8
or 11
installed and you have set the JAVA_HOME
environment variable.
You need to setup JRuby environment to build this plugin. Refer https://github.com/rbenv/rbenv for setting up your rbenv environment.
After setting up rbenv
. Install JRuby
rbenv install jruby-9.2.10.0
rbenv local jruby-9.2.10.0
Check that the environment is configured
ruby --version
jruby 9.2.10
You should make sure you are running jruby
and not ruby
. If the command ruby --version
still shows ruby
and not jruby
, check that PATH contains $HOME/.rbenv/shims
and $HOME/.rbenv/bin
. Also verify that you have this in your bash profile:
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
Then install bundler:
gem install bundler:2.1.4
Follow those instructions to install logstash before moving to the next section.
