Configuring automatic push by successfully build


Posted on Sunday Mar 01, 2015 at 11:19PM in Jenkins


Making Jenkins to push to an another remote repository if build finishes successfully.

Recipe

  1. Create a bare repository

    $ mkdir trader-stable.git
    $ cd trader-stable.git
    $ git init --bare
    Initialized empty Git repository in /Users/Shared/trader-stable.git/
    $
  2. Click Add Repository

  6. Click Add post-build actionGit Publisher

    44eeab12 4cf2 4c4a 81a9 785b99514659
  7. Check Push Only If Build Succeeds

  8. Click Add Tag

    60946cca e837 4245 a2c8 8e74c98c1f23
  9. Enter $BUILD_NUMBER to Tag to push

  10. Check Create new tag

  11. Enter stable to Target remote name

  12. Click Save

Test

$ pwd
/Users/kyle/tmp/trader
$ echo 'push if succeeds test' >> hi.txt
$ git commit -am 'push if succeeds test'
$ git push origin master

Jenkins said Pushing tag 8 to repo stable

Configuring automatic build by push for git repository


Posted on Sunday Mar 01, 2015 at 07:15PM in Jenkins


We can start the build by send request to following URL.

http://YOURHOST/jenkins/job/PROJECTNAME/build

Recipe

In my case, Jenkins is deployed in /, and the server is running on port 18080. so the command to start a build of the job named trader will be:

curl http://localhost:18080/job/trader/build

So put following shell script into $ORIGIN_BARE_REPOSITORY/hooks/post-receive and execute chmod +x post-receive.

#!/bin/sh
curl http://localhost:18080/job/trader/build

Testing

Push some modification as follows:

$ echo hook test >> hi.txt
$ git add hi.txt
$ git commit -m 'hook test'
$ git push origin master

Check the build was run automatically as expected, and the output.

Lean example of integration test Maven project for WildFly


Posted on Monday Feb 23, 2015 at 11:20PM in Technology


I created similar example before, but it was redundant. I created more lean version so leave here with some notes. check my GitHub repository for details.

The project contains AppServer class, which extends ExternalResource so it can be used with @Rule annotation of JUnit as follows. note that mavenit is the name of WAR file to be tested.

public class HelloImplIT {

    @ClassRule
    public static AppServer appServer = new AppServer();
    private static Hello sut;

    @BeforeClass
    public static void beforeClass() {
        sut = appServer.lookup("mavenit", HelloImpl.class, Hello.class);
    }

    @Test
    public void test() {
        Assert.assertEquals("Hello world!", sut.hello());
    }
}

The project is easy to use with both of IDE and standalone. to run IT classes with IDE, you need to launch the application server, deploy the project as WAR package, then run a IT class from IDE. if you launched the server at not 8080 port, specify the port in app-server.port system property.

To run IT classes in standalone Maven, use following command. it automatically launches WildFly instance with port offset of 30000, deploy the WAR file, running IT classes, undeploy the WAR and stops WildFly. the command is intended to use from a Jenkins job.

mvn verify -Pintegration-test-with-wildfly \
 -Djava.home=/Library/Java/JavaVirtualMachines/jdk8/Contents/Home/jre \
 -Djboss-as.home=/Users/kyle/servers/wildfly-8.2.0.Final \
 -Dwildfly.port=39990 \
 -Dapp-server.port=38080 \
 -Dwildfly.jvmArgs="-Djboss.server.base.dir=/Users/kyle/servers/wildfly-8.2.0.Final/standalone-mavenit -Djboss.socket.binding.port-offset=30000 -ea"

You can configure following parameters through command line argument:

  • JAVA_HOME-Djava.home

  • WildFly distribution ⇒ -Djboss-as.home

  • jboss.server.base.dir ⇒ inside -Dwildfly.jvmArgs

  • Port offset ⇒ -Djboss.socket.binding.port-offset inside -Dwildfly.jvmArgs. you need to set -Dwildfly.port and -Dapp-server.port accordingly.


Deploying after integration test with Jenkins


Posted on Wednesday Mar 05, 2014 at 04:09PM in Jenkins


Requirements

  • I want to deploy the production resource after integration test.
  • But some resources are environment-specific.
  • So, after integration test succeeded, I want to replace such resources for production version.

How to achieve it?

  • The deployment job is need to be a parameterized job.
  • After integration test completed, then another mvn starts at post-build step of Jenkins.
    • This mvn does only package goal with no tests.
  • Deployment will be executed by SSH deploy plugin at post-build action of Jenkins.

How to apply this way to a Jenkins job?

  1. Create a parameterized job that can integration-test and deployment be done successfully.
  2. Go to job configuration page
  3. Click “Add post-build step”
  4. Click “Invoke top-level Maven targets”
  5. Select “Run only if build succeeds”
  6. Select Maven Version “Default”
    • Not (Default) which one with enclosed in parentheses. it won't work.
  7. Enter “Goals”
  8. Click “Advanced…”
  9. Enter “POM”, “Properties”.
    • “hogeApp.environmentId=prod” triggers to Maven to include production resources in my pom.xml.
  10. Ensure that there is a post-build action which deploys the artifact to the production environment.
  11. Click “Save” of bottom of the page.
