8080 default port of jenkins so, you should add security inbound rule 8000 port on your IP

4. show the password of jenkins

• Now you can access jenkins by using your ec2 instance public Ip with jenkins default port 8000
• for example ( myIp:8000)
• after that , you can see the jenkins interface
• /var/lib/jenkins/secrets/initialAdminPassword ( using this location to take your unique password to open the jenkins )

Use this in your ubuntu VM

sudo cat /var/lib/jenkins/secrets/initialAdminPassword
