Setup Jenkins Job to start on Git Commit

 

This is the fifth post in the series of ‘Continuous Integration and Delivery with Docker Trusted Registry on Microsoft Azure’. This is a step by step guidance for implementing http://www.docker.com/sites/default/files/UseCase/RA_CI%20with%20Docker_08.25.2015.pdf on Microsoft Azure.

You can read the previous post in this series at https://manesh.me/2015/11/15/continuous-integration-and-delivery-with-docker-trusted-registry-on-microsoft-azure/. In the previous post, we have created a job in Jenkins to have on-demand start based on Git source repository. In this post, we will explore, how we can setup Git/Jenkins to work together to invoke the job for every check-in. To configure and try out this post, you will need write permission to Git repository. I am using a forked repository https://github.com/Manesh-R/hello-jenkins, for this post.

Prerequisites

  • Microsoft Azure Subscription
  • Followed steps in all prior posts
  • Write permission on Git repository (Forking the Git project will be the easiest way)

Setup Sequence

  • Configure GitHub Service Hook
  • Configure Build Trigger on Git Commit
  • Test build trigger with a commit to Git repository

Configure GitHub Service Hook

Open browser and navigate to your GitHub repository (https://github.com/Manesh-R/hello-jenkins). Note that you need admin permissions on the repository.

Click on Settings, then Webhooks & services and then Add service

Search for Jenkins and click on Jenkins (GitHub plugin)

Update Jenkins hook URL, keep service Active and click Add service.

Now for every commit to the repository, service hook will send notification to Jenkins.

Configure Build Trigger on Git commit

Open browser and navigate to http://mme-j-master.southcentralus.cloudapp.azure.com:8080/

Click on job dtr-cicd.

Click on Configure

In project details select Build when a change is pushed to GitHub in Build Triggers and click Save.

Test build trigger with a commit to Git repository

Open browser and navigate to https://github.com/Manesh-R/hello-jenkins/edit/master/README.md

Make a minor modification to the file content and commit changes directly to master.

Now you should see a build automatically triggering on Jenkins server based on the service hook notification. J

Summary

With this we have gone through the complete cycle of setting up a continuous integration / delivery pipeline using Docker & Jenkins on Microsoft Azure.

Setup Jenkins Slave on Microsoft Azure for CICD with DTR

This is the third post in the series of ‘Continuous Integration and Delivery with Docker Trusted Registry on Microsoft Azure’. This is a step by step guidance for implementing http://www.docker.com/sites/default/files/UseCase/RA_CI%20with%20Docker_08.25.2015.pdf on Microsoft Azure.

You can read the previous post in this series at https://manesh.me/2015/11/15/continuous-integration-and-delivery-with-docker-trusted-registry-on-microsoft-azure/.

Prerequisites

  • Microsoft Azure Subscription

Setup Sequence

  • Create virtual machine for Jenkins Slave
  • Assign DNS name for Jenkins Slave machine
  • Install JRE on Jenkins Slave
  • Install and Configure Docker Engine on Jenkins Slave
  • Register slave node in Jenkins Master

Create virtual machine for Jenkins Slave

Open browser and navigate to https://portal.azure.com/

From Azure Portal, click New, then Compute, then Marketplace

Type Ubuntu Server in the search box and press Enter, then click on ‘Ubuntu Server 14‘ from the search results

Read virtual machine image description, choose Resource Manager as the deployment model and click Create

Note: It is important to choose ‘Resource Manager’ deployment model, to have this created in the same resource group of DTR and Jenkins Master.

Provide basic configuration details for the virtual machine (you can change details as per your environment) and click OK

  • Name: mme-j-slave01
  • User name: cicdagent
  • Authentication Type: Password
  • Password: Azure101!
  • Resource Group: DTR
    • Select existing Resource Group, you created for DTR virtual machine
  • Location: South Central US

For size configuration, choose D1 Standard and click Select

Choose default values for optional configurations, and click OK

Review summary details and click OK

Wait for virtual machine to get into state ‘Running’.

Assign DNS Name for Jenkins Slave

Follow the similar steps in previous post to create a DNS name label for the virtual machine. In my environment FQDN of the virtual machine is mme-j-slave01.southcentralus.cloudapp.azure.com

Install JRE on Jenkins Slave

Use SSH to connect to Jenkins Slave machine and execute the following commands.

ssh cicdagent@mme-j-slave01.southcentralus.cloudapp.azure.com

# install jre package on the virutal machine

sudo apt-get install default-jre

Install and Configure Docker Engine on Jenkins Slave

Use SSH to connect to Jenkins Slave machine and execute the following commands.

ssh cicdagent@mme-j-slave01.southcentralus.cloudapp.azure.com

# download and install CS Engine

curl -s https://packagecloud.io/install/repositories/Docker/cs-public/script.deb.sh | sudo bash

sudo apt-get install docker-engine-cs

Since we do not have a valid SSL certificate on Docker Trusted Registry server for HTTPS, we need to ensure that docker service starts with ‘–insecure-registry mme-dtr.southcentralus.cloudapp.azure.com’ option. For this we need to edit /etc/default/docker file.

You can use vim editor to make required changes on the file. To start inserting text in vim, press the ‘i’ key to enter insert mode. When you have finished editing, press ESC to exit insert mode, then type ‘:wq’ to save and exit the editor.

sudo vim /etc/default/docker

Once the file is updated, reboot the Jenkins Slave virtual machine.

sudo reboot

Register slave node in Jenkins Master

Open browser and navigate to http://mme-j-master.southcentralus.cloudapp.azure.com:8080

Click on Manage Jenkins

Click on Manage Nodes

Click on New Node

Enter mme-j-slave01 as the node name, choose option dump slave and click OK

On node details page, provide slave node information. Click on Add button for credentials and create a username with password credential. It is important to keep label for node as docker. This label is used later to associate Jenkins Job to the slave node.

You should see that the node is added and is in active state.
