This is all completed in about a minute, but the time it takes can greatly increase depending on the software being installed.
Once Vagrant finishes setting up the machine, you are left with a completely sandboxed, fully provisioned development environment. Due to the shared folders and networking, you continue using your own editor and your own browser to develop and test your applications, but the code itself runs on the virtual machine. Vagrant handles the entire lifecycle of the machine for you, so in addition to setting up your development environment, Vagrant can do all of the following:. Vagrant is a Swiss Army knife for development environments. It does everything you need to create and manage them, and helps enforce good practices by encouraging the use of automation and an environment that more closely resembles production.
If this ends up being something that a lot of people need, then your plug-in could be merged back into Vagrant core, since Vagrant itself is open source. In order to understand the need for a tool like Vagrant, it is important to understand the old ways that Vagrant is trying to replace.
Prior to Vagrant, the preferred method of working on a web application was to install and configure all the software you needed e. They also work well with multiple projects due to easy virtual hosts in Apache and database isolation with MySQL. But today, modern web applications have a lot more moving parts, a lot more options for underlying technologies, and a lot more overall complexity. For databases, there are now a handful of choices that are equally correct in their valid use case e. In addition to just languages and databases, there are multiple web servers, application servers, and backend services each with their own use cases e.
The various combinations of these technologies that may be used quickly becomes out of hand, and keeping everything properly configured and installed locally is a nightmare. There are other issues with the local install practice as well:. Vagrant is a modern solution to all of these problems.

While not strictly required, Vagrant encourages automation to set up your development environments using shell scripts or configuration management software. Vagrant allows you to work with the same operating system that is running in production, whether your physical development machine is running Linux, Mac OS X, or Windows. Because Vagrant puts your development environment into a virtual machine, working with multiple projects is easy, because each project just get its own virtual machine.
Finally, working with a team is easier than ever, since you can share the virtual machine image. And bringing a new team member on board is as simple as telling them to build their Vagrant machine with a single command. Before even installing Vagrant or seeing how it works, it is important to understand the high-level workflow of Vagrant in an actual working environment. In a world with Vagrant, developers can check out any repository from version control, run vagrant up , and have a fully running development environment without any human interaction.
Developers continue to work on their own machines, in the comfort of their own editors, browsers, and other tools. The existence of Vagrant is transparent and unimportant in the mind of the developer. Vagrant is the workhorse that creates consistent and stable development environments. System operations engineers work on system automation scripts, again using their choice of editors and tools on their own machines. The automation developed by system operations engineers is not only used in production, but also in development. With every vagrant up , developers are getting fully provisioned development environments using the same scripts that are used to set up production.
This way, developers work in environments that mimic production as closely as possible. If something goes wrong, or they just want to start over from a clean slate, developers and operations engineers can run vagrant destroy , which removes all traces of that development environment from their machines. Then a vagrant up again will re-create an identical, fully functioning development environment in a snap. At the end of the day, Vagrant can suspend, halt, or destroy the development environment, keeping the overall system clean. Never again can developers forget to shut down a stray server process and waste precious compute resources.
When ready, vagrant up will bring back a ready-to-go development environment in just a few minutes. The best part of all this is that this knowledge transfers to every project. Whether working on project A, project B, or even at company A or company B, as long as they follow the Tao of Vagrant, the workflow is exactly the same.
Vagrant is a general-purpose tool and can be molded into your environment as you see fit. But it is important to see and understand the larger vision behind Vagrant. There are various ways to achieve what Vagrant does using other technologies. And perhaps the biggest disadvantage of all is losing the workflow Vagrant enforces, forcing you to invent your own or mimic the workflow of Vagrant as closely as possible. Prior to Vagrant 1. However, since version 1.
Vagrant is a layer on top of some virtualization solution. Instead, you could use that virtualization solution directly. VirtualBox is free, but there are also many commercial alternatives e. Each of these can be used to mimic what Vagrant does. It is standard practice for this software to support sharing or exporting virtual machines, shared folders, port forwarding, and so on.
It is completely possible to do everything Vagrant does with these tools. The major downside is that the approach to do this would be completely manual, and cross-platform support would be nontrivial. Additionally, you lose the predictable Vagrant workflow. If you have a very specific goal and are OK with losing the benefits Vagrant offers, then this is a reasonable solution.
For some work environments, this is not an issue, but there is another major negative aspect of containers for development. Containers are highly specific to the host operating system.
OS X provides no container support, and neither does Windows. Therefore, container usage requires an entire team to use the same host operating system. In general, containers are ideal for production usage, since they offer a reasonably secure way to isolate resources within the same operating system without performance overhead. But for development, containers impose strict limitations that are often hard to work with. Another approach is to ditch desktop virtualization altogether and do development directly in the cloud, such as on EC2.
The main benefit of this approach is that it allows developers to work from incredibly low-powered desktop machines in an environment that closely resembles production. It is also possible to mimic much more advanced production environments, since the remote machines can be much more powerful than a typical development machine.

The disadvantage here is that this approach requires an Internet connection, and it can have a much higher financial cost associated with it. If your organization is at the point where they have enough automation to support this sort of remote work, it is generally quite easy to make the switch to Vagrant, if possible.
Vagrant continues to evolve and improve by adding new features, fixing bugs, and improving existing functionality. It is important to understand the available Vagrant versions and what this book covers.
Installing Vagrant and VirtualBox
The first stable release of Vagrant was Vagrant 1. More importantly, perhaps, is that the Vagrant project promises to retain backward compatibility for configuration formats used by stable releases. This means that any projects that work with Vagrant 1. At the time of writing, Vagrant is on the 1. Since version 1. Organizations generally use the latest version of Vagrant because it contains the most bug fixes and improvements, but they also continue to use Vagrant 1.
Because of this, this book covers Vagrant 1. This ensures that the book remains correct while running on the latest, most bug-free core of Vagrant. The features of Vagrant 1. Vagrant must be installed on every computer that you want to run Vagrant-created development environments. Vagrant behaves identically across Linux, Mac OS X, and Windows, so your developers can work on the operating system they feel most productive on.
No more nightmares setting up Linux services on Windows! If you forget this step, Vagrant will give you a nice error message telling you to install it. VirtualBox is the only thing other than Vagrant that must be installed for Vagrant to function properly. Either way, the setup process is order independent. To get started, I recommend installing VirtualBox first.
VirtualBox is open source and cross-platform virtualization software from Oracle. At the time of writing, Vagrant supports VirtualBox versions 4.
Installation of a Vagrant machine
The Vagrant 1. Note that you should always use the latest version of Vagrant in order to get the best compatibility with VirtualBox. Installing VirtualBox also requires setting up a kernel driver for your operating system. The kernel driver is responsible for some low-level virtualization help, makes shared folders possible, optimizes network operating with VirtualBox, and more.
On Linux, you may need to install extra packages and run an extra command in order to set it up. On all platforms, it is highly recommended that you restart your computer after installing VirtualBox, just to make sure the kernel driver starts up cleanly. Like VirtualBox, Vagrant is distributed as a set of packages and installers for various platforms. This release series builds on top of the 1. Despite technically being a beta series, most companies quickly adopt the latest version of Vagrant because Vagrant has a history of being quite stable and each release introduces impressive improvements and better support for every combination of host and guest operating system.
Prior to the installation packages, Vagrant was distributed as a RubyGem.
Why Not WAMP or MAMP?
Installation packages are now the preferred way to install Vagrant, so you should uninstall the RubyGem version and follow the instructions for your platform. The RubyGem-based installation is still supported for Vagrant 1. By understanding how Vagrant versioning works, you can know when it is safe to upgrade, when backward compatibility issues may be introduced, and so on. Vagrant follows a predictable versioning pattern and release cycle. Vagrant versions are in the format of X. Z where X is the major version number, Y is the minor version number, and Z is the patch number. The purpose of using Vagrant is to facilitate the cluster of Consul s in virtual machines.
After installing Vagrant, you can use Initial Box. You can use other people's encapsulated Box, or you can encapsulate Box yourself, such as the following commands:. It's slow to download Box online. You can download Box first, then load the local Box to initialize. Then put the downloaded Box under the boxes folder, and then transfer the command to the boxes directory cd boxes , and then execute the add Box command:.
When initialization is complete, a VagrantFile configuration file is generated in the current directory, which contains some configurations of the virtual machine environment which can be manually modified , and then the virtual machine is started:. After the virtual machine has been started you can check whether it has been started in VirtualBox , you can log in to the virtual machine:.
This command means that you have entered the Ubuntu system and can use it as you would in a virtual machine. When using Vagrant, we encounter a problem: the created Ubuntu virtual machine needs to access the external network, so we need to set the network mode of the virtual machine to Bridged mode, so we use VirtualBox to set it up, but after the setup is successful, every time Vagrant starts the virtual machine, the network mode will be reset, but if using Virdged.
If Virtual Box starts, there's no problem. This problem has been going on for a long time.
The final solution is to modify the Vagrantfile configuration file and add the following configuration:. The bridge is followed by a bridged network mode WiFi network. If it is not set, the network mode will be selected each time the virtual machine is started. Because the previous version of Ubuntu was too low NET Core, and then another one was changed.
