Step 1. Setup JIRA and Jenkins env with Docker images
docker pull atlassian/jira-software
docker volume create –name jiraVolume
docker run -v jiraVolume:/var/atlassian/application-data/jira –name=”jira” -d -p 8080:8080 atlassian/jira-software
docker pull jenkins/jenkins:lts
docker run –name jenkins -d -p 9090:8080 -p 50000:50000 jenkins/jenkins:lts

Step 2. Configure JIRA on http://locahost:8080/ and create project DevOps

Step 3. Configure Jenkins on http://locahost:9090/ and install/setup JIRA Trigger Plugin

Step 4. Create WebHook on JIRA

Step 5. create a Freestyle job on Jenkins

Step 6. Add a comment “build this please” on JIRA, then verify it triggered the Jenkins job successfully!

1. in Jenkins select create new item, give name as "java-web-project", type as "Maven Project". Keep all default value, only add "wildfly:deploy" in "Build => Goals and options" then apply and save.
   
2. in /var/lib/jenkins/workspace/, run maven command to create webapp:
   mvn archetype:generate -DgroupId=com.pythondesign.web -DartifactId=java-web-project -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
   you will get files:

   
   (base) ubuntu@ubunu2004:/var/lib/jenkins/workspace/java-web-project$ tree
   .
   ├── pom.xml
   ├── src
   │   └── main
   │       ├── resources
   │       └── webapp
   │           ├── index.jsp
   │           └── WEB-INF
   │               └── web.xml

3. update pom.xml as below:
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    </dependency>
  </dependencies>
  <build>
    <finalName>java-web-project</finalName>
        <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
         <plugins>
        <plugin>

            <artifactId>wildfly-maven-plugin</artifactId>
            <version>2.1.0.Beta1</version>
            <configuration>
                <hostname>localhost</hostname>
                <port>9990</port>
                <username>admin</username>
                <password>pas8word@</password>
            </configuration>
        </plugin>
         </plugins>
        </pluginManagement>
  </build>
</project>

3. you can test it with command:
   mvn package
   mvn wildfly:deploy
4. now we can click "Build Now" in Jenkins, check the console, you will get:
   BUILD SUCCESS! and verify the webapp on jboss:
   http://192.168.0.43:8090/java-web-project/index.jsp

1. sudo apt install openjdk-8-jdk
2. wget -q -O – https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add –
3. sudo sh -c ‘echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list’
4. sudo apt update
5. sudo apt install jenkins
6. sudo ufw allow 8080
7. (jenkins_url)/restart – Forces a restart without waiting for builds to complete.
