Provision a VM using Packer and Vagrant

About 8 years back I worked for a company serving customers of the Payment Card Industry. They had a dire need of Infrastructure as Code(IaC) to build a Windows Active-Passive Cluster with Connect:Direct and engineers spent day and night to set it up manually. The ruckus created by that is still etched in my mind.

Now when I tried a simple recipe it worked like a charm. It isn’t very complicated as it is a simple test.

I started with this repo.

C:\Packer\ubuntu\ubuntu>packer build -only=vmware-iso -var='ssh_fullname=mirage' -var='ssh_password=mirage' -var-file=ubuntu1804.json ubuntu.json
vmware-iso: output will be in this color.

Warnings for build 'vmware-iso':

* A checksum type of 'none' was specified. Since ISO files are so big,
a checksum is highly recommended.
* Your vmx data contains the following variable(s), which Packer normally sets when it generates its own default vmx template. This may cause your build to fail or behave unpredictably: numvcpus, memsize

Add box to Vagrant

C:\Packer\ubuntu\ubuntu\box\vmware>vagrant box add --name vmwarepackeransible
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'vmwarepackeransible' (v0) for provider:
box: Unpacking necessary files from: file://C:/Packer/ubuntu/ubuntu/box/vmware/
==> box: Successfully added box 'vmwarepackeransible' (v0) for 'vmware_desktop'!


C:\Packer\ubuntu\ubuntu\box\vmware>vagrant init vmwarepackeransible
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`` for more information on using Vagrant.

Shell provisioner in Vagrantfile

config.vm.provision "shell", inline: <<-SHELL
add-apt-repository ppa:openjdk-r/ppa -y
apt-get update
echo "\n----- Installing Java 8 ------\n"
apt-get -y install  openjdk-8-jdk
update-alternatives --config java

SSH into vagrant and check

SHELLvagrant@vagrant:~$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1~18.04-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

There are other scenarious that are complicated but a simple test like this works as expected.
