Need help to create a jar war file from my project

Question

Hello all

I am new to DevOps. I want to make a .jar, .war file from my project which is .php, and upload it on any container.
 I have 3 VM which is 1st is GitLab, 2nd is Jenkins, and 3rd is apache Tomcat all off VMs are running.  

Please suggest to me.

Answer 1

For sake of ease, you can scale down your VM's to 2.

The 3rd VM for git-hub is really not necessary.

For you to make a build in jar or war, you need to install the deploy to container plugin on Jenkins and you will need a pom.XML maven file
