Notes

TO GENERATE WAR FILE
SCM --------> git URL, Username: Password:
In Build --------> Execute shell
mvn clean
mvn compile
mvn exec:java
mvn war:war
Build it

TO DEPLOY WAR FILE IN TOMCAT

Create a job
SCM --------> git URL, Username: Password:
In Build ---------> Invoke top level maven targets
Goals: clean compile war:war
then build it

Manage Jenkins ---------> Manage Plugin -----> Install the deploy to container plugin
Deploy to container

Open terminal
sudo su
cd /opt/tomcat/conf
vi tomcat-users.xml -------------> Insert mode
Username: Anusha
Pass: Anusha
roles: manager-gui, manager-script

Then Stop and Start tomcat
sudo systemctl stop tomcat.service
sudo systemctl start tomcat.service

Configure job
In Post build actions -----------> Deploy war/ear to container
Fill the required
add container ------------> tomcat 9
Username:
Password
URL: http://localhost:8090/
Then build it again and check if war file deployed successfully or not

To Check it , open the url above and got to manage apps --------> list applications ----> at the bottom u can find the war file.

TO DEPLOY WAR FILE IN TOMCAT AS DOCKER CONTAINER

Open Terminal
sudo useradd -m Anusha
sudo passwd Anusha
-----------> give password as Anusha

Add user to docker grp
sudo useername -aG docker Anusha

Create a freestyle job for generating war file
SCM --------> git URL, Username: Password:

In build ---------> Execute shell

mvn clean
mvn compile
mvn exec:java
mvn war:war

Then build it

Manage Jenkins----> Manage Plugins -------> Install publish over SSh plugin
Publish over SSH

Manage Jenkins --------> Configure system ------> SSH servers add
After adding
Name: Dockerhost
Hostname: 172.31.22.6 ..........(IP address)
Username: Anusha
Advanced --------> check box tick ---> Use password as authentication and then
give password then test configuration -----> Success

Configure the same job-----> In Post build Actions
Send build artifacts over SSH
Name: Dockerhost
Source files: target/*.war
Remove: target/
Remote directory: opt/
Then build it

Open Terminal
cd /home/Anusha/opt
sudo vi Dockerfile ------------>
FROM tomcat:latest
RUN cp -R /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps
COPY ./*war /usr/local/tomcat/webapps
esc :wq!
then give docker build -t myimage .

Configure job ---------> In Post build actions
Exec command
cd /home/Anusha/opt
docker stop tomcat
docker rm tomcat
docker rmi myimage
docker build -t myimage .
docker run -p 8093:8080 -d --name tomcat myimage
or -p 5000:8080

then build it

checking : localhost:8093/warfile ----------> war file we get form /home/Anusha/opt ls --- here

DEPLOY WAR FILE IN TOMCAT USING ANSIBLE PLAYBOOK

Create a freestyle job for generating war file
SCM --------> git URL, Username: Password:

In build ---------> Execute shell

mvn clean
mvn compile
mvn exec:java
mvn war:war

Then build it

Open Terminal
sudo su
cd /home/Anusha/opt
sudo vi sample.yml ------------>
---
- name: sample
hosts: localhost
become: yes
tasks:
- name: task1
copy:
src: /home/labuser/opt/maven-war-0.0.1-SNAPSHOT.war
dest: /opt/tomcat/webapps
esc and give :wq!
then give ansible-playbook -i myhosts sample.yml

Configure job ---------> In Post build actions
Exec command
ansible-playbook -i myhosts sample.yml
then build it

checking : localhost:8093/warfile ----------> war file we get form /home/Anusha/opt ls --- here

TO INTEGRATE JENKINS WITH SONARQUBE

Manage Jenkins -----> Manage plugin -----> Install Sonarqube scanner plugin
Sonar scanner plugin

Manage Jenkins -------> Configure system
Sonar server name: Sonar
Server URL : or else give local server as -----------------------------------------------------
Server token authentication:

Manage Jenkins --> manage plugin -> Install Maven Integration plugin
Maven Integration

Create a new pipeline job
In pipeline ----> select pipeline from SCM and select git
give git Url
username:
password:
script path : Jenkins file
Then build it
---------> works if our git repo have jenkins file with the required script to build the pipeline

( or ) Instead of selecting pipeline from SCM give pipeline and write the pipeline script

Create a new freestyle job

SCM --------> git URL, Username: Password:
In Build Environment: ----> Prepare sonar qube scanner environment
In Build ----->
Invoke top level maven targets:
goals: clean Install sonar:sonar

Then build it

TO USE BLUE OCEAN INTERFACE: (JENKINS 2.0)

Manage Jenkins---> Manage plugins ----> Install Blue Ocean Plugin
Blue Ocean

then we can find blue ocean option at right side of the page
