![]() ![]() Only thing different is that Vagrantfile created by vagrant init contains many detailed comments. To achieve substantially equivalent results with previous cat command. Ubuntu-20.04$ vagrant init ubuntu/focal64 To search a official ubuntu 20.04 box (no longer called mirror), we can go to, the copy below content from this web pageįor the content of Vagrantfile, the following commands do the same thing as above Multiple virtual machines can be defined in one single Vagrantfile file, this is more convenient, will be explained below. By modifying the environment variable VAGRANT_CWD, we can change the search start position. For example, if we want to create a Ubuntu 20.04 LTS virtual machine, just create a folder ubuntu-20.04, and then put a file Vagrantfile insideĮxecuting vagrant command will search for Vagrantfile in order, from current to the root folder. ![]() If we want to create multiple virtual machines on the same host, we usually create a separate directory for each Vagrantfile. Let's take a look at how the vagrant command creates, starts, ssh and shutdown a virtual machine.ĭocker has a Dockerfile, which corresponds to Vagrant is Vagrantfile. The current version isĪt this time, using vagrant's up, halt or other sub-commands can be treated as communicating with virtual machine commands such as VirtualBoxVM, VBoxManage. Just select an online box.įirst of all, if we want to use Vagrant under Mac OS X, we should install Virtualbox, then Vagrant, which can be installed with brew commandsĪfter installation, we can run the Vagrant command. Or manually import a compressed virtual machine file exported by others. With Vagrant, no longer to download OS installation ISO image file, then take a long time to setup a new virtual machine step-by-step. Vagrant can support multiple Operation Systems. Understand that Vagrant is just the shell of a virtual machine, so it requires different virtual machine implementations, such as VirtualBox, Hyper-V, VMware, etc., and we can use Vagrant to interact with Docker as well. Since Vagrant corresponds to a virtual machine, the operation status with Vagrant and the installed software will be retained after Vagrant virtual machine shutdown, while the operations status in Docker are all for the current container (copy-on-write), which does not affect the corresponding image, Unless it is committed as a new image with docker commit. Docker image is usually a trimmed system, just has necessary command to run our service. Vagrant is a tool for the development environment, and Docker is a tool for the deployment environment Vagrant operates a standard Linux or Windows operating system, and the Docker is very critical on image size. of the process with a namespace, making the container process look like a virtual OS. Vagrant is essentially a virtual machine shell, allowing us to use Vagrant commands to interact with the virtual machine more conveniently, instead of switching back and forth between the host machine and the virtual machine, it is more convenient to manage multiple virtual machines in one single terminal while Docker is a container, The essence of a container is a process on the host machine, but it is isolated from the file system, process, network, etc. Speaking of Vagrant, I have to mention the similar Docker, in fact, they are quite different, while they both give people the external feeling that they are command line control Linux. Others of HashiCorp's famous tools include Terraform , Consul , Vault , Boundary , Packer , Nomad and Waypoint . ![]() Vagrant is a member of the HashiCorp family. It is time to write a blog for some frequently used Vagrant commands. Many of my demos about Kafka, Docker, Python, Kubernates, and etc. ![]()
