Using the RunDeck API from JRuby scripts

Here are some examples of what you can do with this lib and a few lines of Ruby (for the rubyist that don't fear running on the JVM !)

You will have to download the lib (the .jar file) to use it...

Basic usage

Save the following script in a file named "rundeck.rb", and execute it with "jruby rundeck.rb".

require 'java'
require '/path/to/rundeck-api-java-client-VERSION-jar-with-dependencies.jar'
import org.rundeck.api.RundeckClient

rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

puts "RunDeck uptime : #{rundeck.systemInfo.uptime}"
puts "All RunDeck projects : #{rundeck.projects}"
puts "All RunDeck nodes : #{rundeck.nodes}"
puts "All RunDeck jobs : #{rundeck.jobs}"
puts "All RunDeck running executions : #{rundeck.runningExecutions}"

You can also add the library to the classpath : save the following script in a file named "rundeck.rb", and execute it with "jruby -rjava -J-cp /path/to/rundeck-api-java-client-VERSION-jar-with-dependencies.jar rundeck.rb".

import org.rundeck.api.RundeckClient

rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

puts "RunDeck uptime : #{rundeck.systemInfo.uptime}"
puts "All RunDeck projects : #{rundeck.projects}"
puts "All RunDeck nodes : #{rundeck.nodes}"
puts "All RunDeck jobs : #{rundeck.jobs}"
puts "All RunDeck running executions : #{rundeck.runningExecutions}"

Authentication

Starting with RunDeck API 2, there are 2 ways to authenticate :

  • the login-based authentication : with your login and password
  • the token-based authentication : with a unique token that you can generate from the RunDeck webUI
// using login-based authentication (admin/admin is the default login/password for a new RunDeck instance) :
rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin");

// using token-based authentication :
rundeck = RundeckClient.new("http://localhost:4440", "PDDNKo5VE29kpk4prOUDr2rsKdRkEvsD");

Running a job

import org.rundeck.api.RundeckClient
import org.rundeck.api.OptionsBuilder
import org.rundeck.api.NodeFiltersBuilder

rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

// find a job from its name, group and project
job = rundeck.findJob("my-project", "main-group/sub-group", "job-name")
puts "Found job with ID : #{job.id}"

// trigger a simple job with no options
execution = rundeck.triggerJob(job.id)
puts "Execution started, you can follow it at the URL : #{execution.url}"

// or with options...
execution = rundeck.triggerJob("job-id", OptionsBuilder.new().addOption("option1", "value one").addOption("option2", "value two").toProperties())

// you can also override the nodes on which the job should execute
execution = rundeck.triggerJob("job-id", OptionsBuilder.new().addOption("opt", "value").toProperties(), NodeFiltersBuilder.new().tags("prod+appserv").toProperties())

// last one : you can run a job and wait until its execution is finished :
execution = rundeck.runJob("job-id")
puts "Execution finished ! Status : #{execution.status}, duration : #{execution.duration}"

Running an ad-hoc command

import org.rundeck.api.RundeckClient
import org.rundeck.api.NodeFiltersBuilder

rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

// trigger the execution of the "uptime" command on the RunDeck server
execution = rundeck.triggerAdhocCommand("my-project", "uptime")

// run the "uptime" command on all unix nodes
execution = rundeck.runAdhocCommand("my-project", "uptime", NodeFiltersBuilder.new().osFamily("unix").toProperties())

Running an ad-hoc script

import org.rundeck.api.RundeckClient
import org.rundeck.api.OptionsBuilder
import org.rundeck.api.NodeFiltersBuilder

rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

// trigger the execution of a custom bash script on the RunDeck server
execution = rundeck.triggerAdhocScript("my-project", "/tmp/my-script.sh")

// run a bash script (with options) on all unix nodes
execution = rundeck.runAdhocCommand("my-project", "/tmp/my-script-with-options.sh", OptionsBuilder.new().addOption("option1", "value one").toProperties(), NodeFiltersBuilder.new().osFamily("unix").toProperties())

Exporting jobs

import org.rundeck.api.RundeckClient
rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

rundeck.exportJobsToFile("/tmp/jobs.xml", "xml", "my-project")
rundeck.exportJobToFile("/tmp/job.yaml", "yaml", "job-id")

Importing jobs

import org.rundeck.api.RundeckClient
rundeck = RundeckClient.new("http://localhost:4440", "admin", "admin")

result = rundeck.importJobs("/tmp/jobs.xml", "xml")
puts "#{result.succeededJobs.size} jobs successfully imported, #{result.skippedJobs.size} jobs skipped, and #{result.failedJobs.size} jobs failed"
