What is Pipeline in Jenkins

• Workflow with group of events or jobs that are chained & integrated with each other in sequence.
• Every job in a pipeline has some dependency on one or more other jobs

Continuous Delivery Pipeline

• Build Jobs
  • Notification Feedback
• Deploy Jobs
  • Notification Feedback
• Test Jobs
  • Notification Feedback
• Release Jobs
  • Notification Feedback

Jenkins Email Notifications

Note: firewall settings might need to be updated for BOTH outbound & inbound ports

• Extended E-mail Notification
  • SMTP server
  • Default user E-mail suffix
  • Use SMTP Authentication
    • UserName
    • Password
  • Advanced Email Properties
  • Use SSL
  • SMTP port
    • 465
  • Charset UTF-8

Test Configuration

'Email was successfully sent'

PreReq: JDK7/8

Add tomcat user & add to sudoer list

sudo adduser tomcat
sudo passwd tomcat
Changing password for user tomcat.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
sudo gpasswd -a tomcat wheel
Adding user tomcat to group wheel

Create tomcat group & adduser

sudo groupadd tomcat

Then create a new tomcat user. We'll make this user a member of the tomcat group, with a home directory of /opt/tomcat (where we will install Tomcat), and with a shell of /bin/false (so nobody can log into the account):

sudo useradd -M -s /bin/nologin -g tomcat -d /opt/tomcat tomcat

Now that our tomcat user is set up, let's download and install Tomcat.

Automated Deployment in Jenkins

put sample.war in project workspace

place sample.war in the build workspace

/opt/jenkins/workspace/AutomatedDeploymentTest/sample.war

General

Description

<h3>Deploy a war file to system</h3>

Use Custom Workspace

${JENKINS_HOME}/workspace/AutomatedDeploymentTest

Display Name

AutomatedDeploymentTest

Build

Command

pwd

Post Build

Deploy WAR/EAR file to container

**/*.war

Context path

sample.war

Containers

Tomcat 7.x

Credentials

deployer | deployer

Note: Tomcat user MUST have 'manager-script' role assigned in tomcat [ /opt/tomcat/conf/tomcat-users.xml ]

<user username="deployer" password="deployer" roles="manager-script"/>

Tomcat URL

Automated Deployment ( Jenkins Chaining )

CI Stages

Build > Deploy > Test > Release

Automated Deployment is the process of Automating the deployment process in a Continuous Delivery system

• Developers > Commit > VCS
• Jenkins Build Job > Poll > VCS
• Jenkins Deploy > Environments (Functional, Performance)
• Jenkins Deploy > Environments (Production)

Catlight For Jenkins Integration

Manage Plugins > Deploy to container

Jenkins Integration with Git

• Create Java project
• Push to GitHub

Jenkins Jobs

Add Project Item

Descriptiong

Source Code Management

None \ Git \ Subversion

Build Triggers

• Remotely
  • Add Token (1234)
  • Jenkins will provide URL
    • <ip>:8080/job/TestJavaProject1/build?token=1234
    • Tried wget on linux, but getting access denied(is it possible?)
      • even with --referer and --user uname:pwd
• Before Build
• After Build
  • Cascade Projects
    • Based on health?

Basic Jenkins Configurations

Manage Jenkins > Configure System

Managing Users & Roles

Default Logic

• Before Roles are Created, ALL users are admin
• Need Role Strategy Plugin to create/manage 'Roles'
  •  
• Create Roles, then assign users to lock system down
• Manage Jenkins > Manage Users > Create User
• API Token
• User must login to view the API Token ( for REST calls to Jenkins )

Role Strategy Plugin

Manual Installation

Download Manually

• https://wiki.jenkins.io/display/JENKINS/Role+Strategy+Plugin
• https://github.com/jenkinsci/role-strategy-plugin
• *.hpi file

cd /var/lib/jenkins/plugins
wget --no-cookies "https://updates.jenkins.io/download/plugins/role-strategy/2.8.1/role-strategy.hpi"
systemctl restart jenkins
