Preparing easy-jenkins demo, 2018-06-22

Executive Summary

This document details the steps to reproduce the demo given by @gmacario during the last day of the Jenkins & Java 10+ Hackathon which took place on 2018-06-22.

YouTube Video: https://www.youtube.com/watch?v=1ZX9qA0AZjM (from 18:52 to 28:10)

See #268

Prerequisites

Please refer to section "System Requirements" of https://github.com/gmacario/easy-jenkins

Step-by-step instructions

Login to a Bash shell on the machine where you installed Docker (in our example, login as gmacario@mac-tizy)

Deploy easy-jenkins inside a VirtualBox VM

Clone easy-jenkins source code from GitHub

mkdir -p $HOME/github/gmacario && cd $HOME/github/gmacario && \
[ ! -e easy-jenkins ] && git clone https://github.com/gmacario/easy-jenkins

Switch to development branch

cd $HOME/github/gmacario/easy-jenkins && \
git checkout feature/install-nexus-oss && git pull --all --prune

Bring-up easy-jenkins

cd $HOME/github/gmacario/easy-jenkins && \
./runme.sh

If everything is OK, you should get an output similar to the following:

...
Creating easy-jenkins_myjenkins_1 ... done
INFO: Run the following command to configure your shell:
INFO: eval $(docker-machine env easy-jenkins)
INFO: Browse http://192.168.99.100:9080/ to access the Jenkins dashboard
INFO: Initial administrator password: c253570cfcec43b79e92f47008dc0ac0
gmacario@mac-tizy:~/github/gmacario/easy-jenkins (wip/try-java10-jcasc)$

NOTE: Take note of the displayed URL and initial administrator password (they may differ from the ones shown here) since you will need them later on.

(Optional) Check docker-compose logs

eval $(docker-machine env easy-jenkins) && \
docker-compose logs -f

Configure easy-jenkins instance

Browse ${JENKINS_URL} -- example: http://192.168.99.100:9080/

  • On page "Unlock Jenkins", paste the Jenkins initial administrator password (see output of ./runme.sh or type docker-compose logs), then click "Continue"
  • On page "Getting Started", click "Install suggested plugins"
  • On page "Create First Admin User", fill in the requested details, then click "Save and Continue"
  • On page "Instance Configuration", accept the proposed value for Jenkins URL, then click "Save and Finish"
  • If requested, click button "Restart" and refresh the browser until you get the "Welcome to Jenkins!" login page
  • On page "Welcome to Jenkins!", login with the credentials of the first admin user you have created, then click "Sign in"
  • On the main Jenkins dashboard page, click "Build Executor Status", then click the "Configure" icon of node "master" and fill in the following data
    • Labels: docker
    • Click "Save"

Install sample Pipelines (my-jenkins-pipelines)

Browse ${JENKINS_URL}

  • Click "Open Blue Ocean"
  • Click "Create a new Pipeline"
  • Where do you store your code? GitHub
  • Connect to GitHub: Create an access token
    • On page "New personal access token" fill in the following data:
      • Token description: Choose a meaningful name (example: easy-jenkins @mac-tizy)
      • Click "Generate token"
    • Copy the access token and paste it to the Pipeline setup page, then click "Connect"
  • Which organization does the repository belong to? An organization you belong to (example: gmacario)
  • Choose a repository: my-jenkins-pipelines (you may fork it from https://github.com/gmacario/my-jenkins-pipelines)
  • Click "Create Pipeline"

Result: TODO

Tear-down

cd $HOME/github/gmacario/easy-jenkins && \
eval $(docker-machine env easy-jenkins) && \
docker-compose down -v && \
docker-machine stop easy-jenkins

If anything fails...
