Vagrant

 

 Vagrant Overview :

• Vagrant is a computer software for creating and configuring virtual development environments

• It can be seen as a wrapper around virtualization software such as VirtualBox, KVM, VMware and around configuration management software such as Ansible, Chef, Salt or Puppet

• Vagrant is a simpler way for Virtualization and Configuration Management.


Uses of Vagrant :

• Vagrant is used to set up one or more virtual machines by:

• Importing pre-made images (called "boxes")

• Setting VM-specific settings (IP address, hostnames, port forwarding, memory, etc.)

• Running provisioning software like Puppet or Chef

• Set Up Multi-VM Networks with Ease

• Source Control

• Various Platforms


Uses of Vagrant :

• For Developers

• If you are a developer, Vagrant will isolate dependencies and their configuration within a single disposable, consistent environment, without sacrificing any of the tools you are used to working with (editors, browsers, debuggers, etc.).

• For Operators

• If you are an operations engineer or DevOps engineer, Vagrant gives you a disposable environment and consistent workflow for developing and testing infrastructure management scripts

• For Designers

• If you are a designer, Vagrant will automatically set everything up that is required for that web app in order for you to focus on doing what you do best: design


Alternatives to Vagrant :

• Docker

• Kubernetes

• Nanobox

• Apache Mesos

• virt-manager

• Stakkr

• Singularity Container

• Fig

• FreeBSD Jails

• BoxGrinder

• Arkose

• Datacol

• plash


Vagrant Versions : Vagrant has installers for:

• Debian

• Windows

• CentOS

• Linux

• macOS

• Arch Linux


Installing Vagrant :

• Before we start with Vagrant we need to install Virtual Box as Vagrant uses it to run the virtual machines

• Download VirtualBox from https://www.virtualbox.org/wiki/Downloads

• Next download and install Vagrant

• Go to https://www.vagrantup.com/downloads.html

• And get the appropriate installer or package for your platform

• Install the package using standard procedures for your operating system


Setting up Vagrant :

• Once you have vagrant on your machine, open the terminal (Linux or Mac) or command prompt (Windows)

• Create a separate directory for vagrant and initialise a vagrantfile

mkdir my_vagrant 

cd my_vagrant 

vagrant init


Setting up Vagrant :

• After creating a new Vagrantfile, specifying the box to use for your Vagrant environment is always the first step

• Instead of building a virtual machine from scratch, which would be a slow and tedious process, Vagrant uses a base image to quickly clone a virtual machine

• These base images are known as boxes in Vagrant, we will use centos box

• Start the VM and access it using ssh using Putty or Oracle VM Virtualbox

vagrant box add centos-6.5 

vagrant up

Terraform

  Terraform is an infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently. HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle. Terraform can manage low-level components like compute, storage, and networking resources, as well as high-level components like DNS entries and SaaS features. How does Terraform work? Terraform creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API. HashiCorp and the Terraform community have already written  thousands of providers  to manage many different types of resources...

Different Types of Reports in Scrum - Agile

Image
  Introduction to Agile Reporting I’m not going to elaborate on the Agile Framework itself here.  1. Sprint Burndown At a Sprint-level, the burndown presents the  easiest way to track and report status  (the proverbial  Red / Amber / Green ), i.e., whether your Sprint is on or off-track, and what are the chances of meeting the Sprint goals. The burndown chart – when used right – can provide  near-real time updates  on Sprint progress. “If your team do it right, then they would take in just the right amount of work into a sprint.” At the beginning of a Sprint, the Scrum team perform Sprint Planning and agree to take on development work worth a certain number of Story points. This forms the basis for the Sprint Burndown chart. The total story points agreed at the beginning of the sprint make up the y-axis, and the individual dates in the Sprint make up x-axis. If your team do it right, then they would take in just the right amount of work into ...
