3. Virtualizing devopsubuntu1804 on Vagrant

This section covers easy to use steps to get started with downloading and virtualizing devopsubuntu1804 virtual environment.

3.1. Single Machine Mode:

Single Machine mode is a mode where you will only be initializing a fresh vagrant virtual envrionment to usedevopsubuntu1804. Open CMD (for Windows host) or Terminal (for Linux/OSX host), then change to a directory of your liking on the Command Prompt or Terminal and run the following command:

vagrant init darkwizard242/devopsubuntu1804

Now that Vagrantfile has been created for devopsubuntu1804, you can initialize/boot up the box (it will download the box if not already downloaded) using the following command:

vagrant up

Once the box is up, do vagrant ssh and you will be within the virtualized box.

3.2. Multi Machine Mode:

As per Vagrant's website, "Vagrant is able to define and control multiple guest machines per Vagrantfile. This is known as a 'multi-machine' environment." So if you are running in a multi-machine mode, you can simple add the following chunk within the existing Vagrantfile:

config.vm.define "mydevopsbox" do |mydevopsbox|
   mydevopsbox.vm.box = "darkwizard242/devopsubuntu1804"
   mydevopsbox.vm.hostname = 'mydevopsbox'
end

Now run the following command so that the box can be downloaded (if not already) and be booted up:

vagrant up mydevopsbox

Once the box is up, do vagrant ssh mydevopsbox and you will be within the virtualized box.

4. Users - for devopsubuntu1804 Vagrant box

Docker, Ansible and Jenkins each have their own respective system users i.e. docker , ansible & jenkins.

Like any other vagrant box, you can easily ssh into devopsubuntu1804 using the default vagrant ssh command and make use of any of the other system level users or application level ones as you like.

4.1. Type and list of users and passwords:

Below is table listing the type of users as well as their usernames and passwords:

User Type Username Password
System User vagrant password
System User root password
System User docker password
System User ansible password
System User jenkins password

NOTE: Though, the passwords for all of the users have been set by default by me so that anyone can use them easily. I would highly recommend to change the passwords of system level users via root user using the following commands:

  • passwd vagrant
  • passwd root
  • passwd docker
  • passwd ansible
  • passwd jenkins

4.2. Users and permissions:

Following users have already been added as sudoers with privileges to perform desired operations without supplying passwords:
