Packer will not install vagrant, nor will it install the underlying virtualization platforms or extra providers; We expect when you run this builder that you have already installed what you need. By default, this builder will initialize a new Vagrant workspace, launch your box from that workspace, provision it, call vagrant package to package it into a new box, and then destroy the original box.

Please note that vagrant will not remove the box file from your system we don't call vagrant box remove. You can change the behavior so the builder doesn't package it not all provisioners support the vagrant package command by setting the skip package option. Please note that if you are using the Vagrant builder, then the Vagrant post-processor is unnecesary because the output of the Vagrant builder is already a Vagrant box; using that post-processor with the Vagrant builder will cause your build to fail.

Similarly, since Vagrant boxes are already compressed, the Compress post-processor will not work with this builder. If your source is a.

You may only set one or the other, not both. We always create this directory and run from inside of it to prevent Vagrant init collisions.

If unset, it will be set to packer- plus your buildname. Defaults to unset. Valid values are nonemd5sha1shaor sha Our default template can be found here.

You must provide a template if your default vagrant provider is Hyper-V. Below is a Hyper-V compatible template. Defaults to "halt". Currently this builder only works for SSH connections, and automatically fills in all information needed for the ssh communicator using vagrant's ssh-config. If you would like to connect via a different username or authentication method than is produced when you call vagrant ssh-configthen you must provide the.

Seven elements of the modern Application Lifecycle.Learn the Learn how Packer fits into the. Packer also has the ability to take the results of a builder such as an AMI or plain VMware image and turn it into a Vagrant box.

This is done using post-processors. These take an artifact created by a previous builder or post-processor and transforms it into a new one.

In the case of the Vagrant post-processor, it takes an artifact from a builder and transforms it into a Vagrant box file. Post-processors are a generally very useful concept. While the example on this getting-started page will be creating Vagrant images, post-processors have many interesting use cases. For example, you can write a post-processor to compress artifacts, upload them, test them, etc.

If you followed along in the previous page and setup DigitalOcean, Packer can't currently make Vagrant boxes for DigitalOcean, but will be able to soon. Post-processors are added in the post-processors section of a template, which we haven't created yet. Modify your example. Your template should look like the following:. In this case, we're enabling a single post-processor named "vagrant".

This post-processor is built-in to Packer and will create Vagrant boxes. You can always create new post-processorshowever. The details on configuring post-processors is covered in the post-processors documentation. Just run a normal packer build and it will now use the post-processor. The command should look like the following:.

But where did the Amazon EBS builder artifact go?

When using post-processors, Vagrant removes intermediary artifacts since they're usually not wanted. Only the final artifact is preserved.

This behavior can be changed, of course. Changing this behavior is covered in the documentation. Typically when removing intermediary artifacts, the actual underlying files or resources of the artifact are also removed. For example, when building a VMware image, if you turn it into a Vagrant box, the files of the VMware image will be deleted since they were compressed into the Vagrant box. Seven elements of the modern Application Lifecycle. Why Use Packer?Packer: Create identical machine images for multiple platforms from a single source configuration.

Packer automates the creation of any type of machine image. It embraces modern configuration management by encouraging you to use automated scripts to install and configure the software within your Packer-made images; Vagrant: A tool for building and distributing development environments. Vagrant provides the framework and configuration format to create and manage complete portable development environments. These development environments can live on your computer or in the cloud, and are portable between Windows, Mac OS X, and Linux.

Packer and Vagrant are primarily classified as "Infrastructure Build" and "Virtual Machine Management" tools respectively. Packer and Vagrant are both open source tools.

It seems that Vagrant with LaunchDarkly is almost a five year old company, and our methodology for deploying was state of the art We recently undertook a project to modernize the way we deploy our software, moving from Ansible -based deploy scripts that executed on our local machines, to using Spinnaker along with Terraform and Packer as the basis of our deployment system. We've been using Armory 's enterprise Spinnaker offering to make this project a reality. We are starting to work in automated provisioning and management with TerraformPackerand Ansible.

For this we chose Vagrant. This, combined with Chef, allows us to do our local dev in sandboxed Linux instances running locally via VirtualBox in a configuration as similar to production as possible.

In addition to making dev environment setup much easier than it used to be, this ensures that each engineer has a consistent environment that is ready to run tests out of the box. The user SSHs into the local linux server and runs spec commands like they would on their host OS, and generally everything Just Works.

Most people on our team combine this with Zeus, which allows the Rails environment to be preloaded for lightning fast relatively speaking test runs. Not blazing fast but we pick Vagrant for all our projects because the console mode without gui leads to a low consumption of ram memory making it the best way for DevOps ready environment requiring less configuration. Vagrant allows me to ensure that anyone I'm collaborating with will be able to test my web application in the same environment.

This helps to reduce the number of defects when our software goes to production. Building development environments that closely match real world web environments, enabling more rapid and accurate testing and development. Packer Stacks. Vagrant 5.

Need advice about which tool to choose? Ask the StackShare community! Packer vs Vagrant: What are the differences? Some of the features offered by Packer are: Super fast infrastructure deployment. Packer images allow you to launch completely provisioned and configured machines in seconds, rather than several minutes or hours. Multi-provider portability. Improved stability.Learn the Learn how Packer fits into the. There are a handful of terms used throughout the Packer documentation where the meaning may not be immediately obvious if you haven't used Packer before.

Luckily, there are relatively few. This page documents all the terminology required to understand and use Packer. The terminology is in alphabetical order for quick referencing. Artifacts are the results of a single build, and are usually a set of IDs or files to represent a machine image.

Every builder produces a single artifact. For the VMware builder, the artifact is a directory of files comprising the created virtual machine. Builds are a single task that eventually produces an image for a single platform. Multiple builds run in parallel. Builders are components of Packer that are able to create a machine image for a single platform. Builders read in some configuration and use that to run and generate a machine image.

A builder is invoked as part of a build in order to create the actual resulting images. Builders can be created and added to Packer in the form of plugins. Commands are sub-commands for the packer program that perform some job. An example command is "build", which is invoked as packer build. Packer ships with a set of commands out of the box in order to define its command-line interface. Post-processors are components of Packer that take the result of a builder or another post-processor and process that to create a new artifact.

Examples of post-processors are compress to compress artifacts, upload to upload artifacts, etc. Provisioners are components of Packer that install and configure software within a running machine prior to that machine being turned into a static image. They perform the major work of making the image contain useful software.

Example provisioners include shell scripts, Chef, Puppet, etc.Since I am a bit tired of yapping the same every single time, I've decided to write it up and share with the world this way, and send people to read it instead.

I will explain it on "live-example" of how the Rome got built, basing that current methodology exists only of readme. It always starts with an app, whatever it may be and reading the readmes available while Vagrant and VirtualBox is installing and updating.

As our Vagrant environment is now functional, it's time to break it! Sloppy environment setup? This is the point, and the best opportunity, to upcycle the existing way of doing dev environment to produce a proper, production-grade product. I should probably digress here for a moment and explain why. I firmly believe that the way you deploy production is the same way you should deploy develop, shy of few debugging-friendly setting. This way you avoid the discrepancy between how production work vs how development works, which almost always causes major pains in the back of the neck, and with use of proper tools should mean no more work for the developers.

That's why we start with Vagrant as developer boxes should be as easy as vagrant upbut the meat of our product lies in Ansible which will do meat of the work and can be applied to almost anything: AWS, bare metal, docker, LXC, in open net, behind vpn - you name it. We must also give proper consideration to monitoring and logging hoovering at this point. My generic answer here is to grab ElasticsearchKibanaand Logstash.

While for different use cases there may be better solutions, this one is well battle-tested, performs reasonably and is very easy to scale both vertically within some limits and horizontally. If we are happy with the state of the Ansible it's time to move on and put all those roles and playbooks to work.

For me, the choice is obvious: TeamCity. It's modern, robust and unlike most of the light-weight alternatives, it's transparent. What I mean by that is that it doesn't tell you how to do things, doesn't limit your ways to deploy, or test, or package for that matter.

Instead, it provides a developer-friendly and rich playground for your pipelines.

You can do most the same with Jenkinsbut it has a quite dated look and feel to it, while also missing some key functionality that must be brought in via plugins like quality REST API which comes built-in with TeamCity. It also comes with all the common-handy plugins like Slack or Apache Maven integration.

The exact flow between CI and CD varies too greatly from one application to another to describe, so I will outline a few rules that guide me in it: 1. Make build steps as small as possible. This way when something breaks, we know exactly where, without needing to dig and root around. All security credentials besides development environment must be sources from individual Vault instances. This is pretty self-explanatory, as anything besides dev may contain sensitive data and, at times, be public-facing.Learn the Learn how Vagrant fits into the.

Vagrant is a tool focused on providing a consistent development environment workflow across multiple operating systems. Docker is a container management that can consistently run software as long as a containerization system exists. Containers are generally more lightweight than virtual machines, so starting and stopping containers is extremely fast.

Docker uses the native containerization functionality on macOS, Linux, and Windows.

Currently, Docker lacks support for certain operating systems such as BSD. If your target deployment is one of these operating systems, Docker will not provide the same production parity as a tool like Vagrant.

Vagrant will allow you to run a Windows development environment on Mac or Linux, as well. For microservice heavy environments, Docker can be attractive because you can easily start a single Docker VM and start many containers above that very quickly. This is a good use case for Docker.

Docker Vs Vagrant

Vagrant can do this as well with the Docker provider. A primary benefit for Vagrant is a consistent workflow but there are many cases where a pure-Docker workflow does make sense. Both Vagrant and Docker have a vast library of community-contributed "images" or "boxes" to choose from.

Vagrant vs. Docker Vagrant is a tool focused on providing a consistent development environment workflow across multiple operating systems.Learn the Learn how Vagrant fits into the. Vagrant and Terraform are both projects from HashiCorp. Vagrant is a tool focused for managing development environments and Terraform is a tool for building infrastructure.

Terraform can describe complex sets of infrastructure that exist locally or remotely. It is focused on building and changing that infrastructure over time.

The minimal aspects of virtual machine lifecycle can be reproduced in Terraform, sometimes leading to confusion with Vagrant. Vagrant provides a number of higher level features that Terraform doesn't. Synced folders, automatic networking, HTTP tunneling, and more are features provided by Vagrant to ease development environment usage. Because Terraform is focused on infrastructure management and not development environments, these features are out of scope for that project.

The primary usage of Terraform is for managing remote resources in cloud providers such as AWS. Terraform is designed to be able to manage extremely large infrastructures that span multiple cloud providers. Vagrant is designed primarily for local development environments that use only a handful of virtual machines at most. Vagrant is for development environments. Terraform is for more general infrastructure management. Seven elements of the modern Application Lifecycle. What is Vagrant? Vagrant vs.
