Clone multiple VM's and create multiple VM's using vagrant

Vagrant is an excellent tool for automation and doing proof of concepts (POC's). In many of the POC's you might need cluster and vagrant can do the clustering in matter of minutes by cloning an existing VM and then making into multiple Virtual machines


  • You have basic idea of Linux & vagrant
  • we are going to use centos/7 for vagrant guest
  • The host is Fedora25/Redhat/CentOs system. Can be easily done for ubuntu as well

Let's see the overall Summary of what we are doing to do

  • create a working directory
  • download and install virtualbox, then vagrant
  • clean-up any unwanted boxes you have.
  • putting the config file and provisioning
  • Validating the nodes

Creating a working Directory

sudo su -
mkdir /opt/vagrantOps
cd /opt/vagrantOps

Download and Install vbox, vagrant to your host (Fedora 25)

vi /etc/yum.repos.d/virtualbox.repo  # with contents as per Virtualbox recommendation

dnf install VirtualBox-5.1   # This will install vbox  from above repo
dnf install vagrant              # Vagrant core
dnf install -y vagrant vagrant-libvirt libvirt-devel   # Addons to vagrant

clean-up and purge (if you want to start from scratch)

vagrant box list  # to check list of boxes available
vagrant global-status # Will show all running and available VM's
vagrant destroy -f ${id}   # Note the id from above command and destroy them

putting the config file and provision

vagrant init        # Ensure you are in vagrantOps directory and will create Vagrantfile
# Copy code from github repo  and paste it to Vagrantfile
# The config file will provision 4 VM nodes with sample node names

Validating the nodes

vagrant global-status # Will show all running and available VM's
vagrant ssh diaryfolio_vm1   # name of the VM1
vagrant ssh diaryfolio_vm2   # name of the VM2

Syslog Standards: A simple Comparison between RFC3164 & RFC5424

Syslog Standards: A simple Comparison between RFC3164 (old format) & RFC5424 (new format) Though syslog standards have been for quite long time, lot of people still doesn't understand the formats in detail. The original standard document is quite lengthy to read and purpose of this article is to explain with examples Some of things you might need to understand The RFC standards can be used in any syslog daemon (syslog-ng, rsyslog etc.) Always try to capture the data in these standards. Especially when you have log aggregation like Splunk or Elastic, these templates are built-in which makes your life simple. Syslog can work with both UDP & TCP  Link to the documents the original BSD format ( RFC3164 ) the “new” format ( RFC5424 ) RFC3164 (the old format) RFC3164 originated from combining multiple implementations (Year 2001)

VS Code & Portable GIT shell integration in Windows

Visual Studio Code & GIT Portable shell Integration Summary Many of your corporate laptop cannot install programs and it is quite good to have them as portable executables. Here we find a way to have Portable VS Code and Portable GIT and integrate the GIT shell into VS Code Pre-Reqs VS Code (Install version or Portable ) GIT portable Steps Create a directory in your Windows device (eg:  C:\installables\ ) Unpack GIT portable into the above directory (eg it becomes: C:\installables\PortableGit ) Now unpack Visual Studio (VS) Code and run it. The default shell would be windows based Update User or Workspace settings of VS Code (ShortCut is:  Control+Shift+p ) Update the settings with following setting { "workbench.colorTheme": "Default Dark+", "git.ignoreMissingGitWarning": true, "git.enabled": true, "git.path": "C:\\installables\\PortableGit\\bin\\git.exe", ""
