Continuous Integration and deployment of Angular 2+ application using Jenkins on AWS EC2
Install Jenkins on AWS EC2
Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Mac OS X and other Unix-like operating systems. As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project.
Prerequisites
EC2 Instance
Security Group with Port 8080 open for internet
Java v1.8.x
Install Java
We will be using open java for our demo, Get the latest version from http://openjdk.java.net/install/
#yum install java-1.8*
yum -y install java-1.8.0-openjdk
#Confirm Java Version and set the java home
java -version
find /usr/lib/jvm/java-1.8* | head -n 3
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04–1.el8_0.x86_64
export JAVA_HOME
PATH=$PATH:$JAVA_HOME
# To set it permanently update your .bash_profile
vi ~/.bash_profile
The output should be something like this,
[root@~]# java -version
openjdk version “1.8.0_151”
OpenJDK Runtime Environment (build 1.8.0_151-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
Install Jenkins
We can install jenkins using the rpm or by setting up the repo. We will set up the repo so that we can update it easily in the future.
Get the latest version of jenkins from https://pkg.jenkins.io/redhat-stable/ and install
yum -y install wget
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm — import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
yum -y install jenkins
Start Jenkins
# Start jenkins service
service jenkins start
# Setup Jenkins to start at boot,
chkconfig jenkins on
Accessing Jenkins
By default jenkins runs at port 8080, You can access jenkins at
http://YOUR-SERVER-PUBLIC-IP:8080
Configure Jenkins
The default Username is admin
Grab the default password
Password Location:/var/lib/jenkins/secrets/initialAdminPassword using cat command
Skip Plugin Installation; We can do it later
Change admin password
Admin > Configure > Password
Configure java path
Manage Jenkins > Global Tool Configuration > JDK
Test Jenkins Jobs
Create “new item”
Enter an item name — AngularProject
Chose Freestyle project
Under the Build section Execute shell: echo “Welcome to Jenkins Demo”
Save your job
Build job
Check “console output”
Configure Git plugin on Jenkins
Git is one of the most popular tools for version control system. you can pull code from git repositories using jenkins if you use github plugin.
Prerequisites
Jenkins server
Install Git on Jenkins server
Install git packages on jenkins server
yum install git -y
Setup Git on jenkins console
Install git plugin without restart
Manage Jenkins > Jenkins Plugins > available > github
Configure git path
Manage Jenkins > Global Tool Configuration > git
Install Latest Nodejs and PM2 on AWS EC2
Step 1 — Configure Yum Repository
First of all, we need to enable node.js yum repository in our system provided by the Node.js official website. You also need development tools to build native add-ons to be installed on your system.
For Latest Release-
sudo yum install -y gcc-c++ make
curl -sL https://rpm.nodesource.com/setup_13.x | sudo -E bash -
For Stable Release-
sudo yum install -y gcc-c++ make
curl -sL https://rpm.nodesource.com/setup_12.x | sudo -E bash -
Step 2 — Install Node.js on Amazon Linux
After adding a yum repository in your system let’s install the Node.js package. NPM will also be installed with node.js. This command will also install many other dependent packages on your system.
sudo yum install -y nodejs
sudo npm install pm2 -g
Setup NodeJS Plugin on jenkins console
Install NodeJS plugin without restart
Manage Jenkins > Jenkins Plugins > available > NodeJs Plugin
Configure Node JS installations
Manage Jenkins > Global Tool Configuration > NodeJs Installations
Jenkin Jobs —
Create a Free style project in Jenkins
Configure the Source Code management
Add webhook in github project’s setting..
- Payload URL — http:<EC2 instance IP: 8080>/github-webhook/
- Content-Type -application/json
Select the build trigger in Jenkins — Github hook trigger for GITScm Polling
In Build Section
we can further configure post build for test and deploy build on server container.
