The Jenkins server example

In this example we will learn how to set up a basic environment with Lago. The environment will consist of three virtual machines that will host Jenkins infrastructure.

The VMs

  • “vm0-server” - Jenkins server
  • “vm1-slave” - Jenkins slave
  • “vm2-slave” - Jenkins slave

The network

The vms will be connected to the same network, There will be also connectivity between the vms host and the internet.


git clone

Let’s start !

From within the cloned repository, run the following commands:

  • Create the environment.
lago init
  • Start the vms.
lago start
  • Installing the vms:
  • Jenkins will be installed on the server.
  • OpenJDK will be installed on the slaves.
lago deploy

The environment is ready! Now you can open your favorite browser, enter “vm0-server-ip-adress:8080” and the jenkins dashboard will be opened. How to figure out what is the ip of “vm0-server” ? Check out the following commands:

  • Open a shell to vm0-server (for any other vm, just replace ‘vm0-server’ with the name of the machine)
lago shell vm0-server
  • Print some usefull information about the environment.
lago status

When you done with the enviroment:

  • Turn off the vms.
lago stop

To turn on the vms, use:

lago start

And if you will not have a need for the environment in the future:

  • Delete the vms.
lago destroy
