Vagrant is a lightweight dev-envs tool.

As someone that likes to experiment (languages/tecnologies), it can often be a massive pain to get local dev-envs set up before jumping into a new project.

... the dependencies hell ... the settings hell ...

Tools like Vagrant exist to make this process much easier. Once again, the idea is a tiny VM fully configured. Changes only last as long as the VM exists and they don't pollute the host machine w unused runtimes and SDKs.

Vagrant: ability to define a complete dev-env within a single, human-readable file. This file can be kept in the project's repo so any time you need to do further work, you can simply spin up the dev-env and get to work.

  • 2. Creo un Vagrant env using the hashicorp/bionic64 box

box ~ base image for a vm, usually defining the underlying os and eventual installed runtimes.

boxes at Vagrant Cloud, or alternatively created by us.

vagrant init  # new Vagrantfile
```sh

```rb
Vagrant.configure("2") do |config|
  config.vm.box = "base"
end
vagrant up
The provider 'virtualbox' that was requested to back the machine 'default' 
is reporting that it isn't usable on this system. The reason is shown below:

Vagrant could not detect VirtualBox! Make sure VirtualBox is properly installed.
Vagrant uses the `VBoxManage` binary that ships with VirtualBox, and requires
this to be available on the PATH. If VirtualBox is installed, please find the
`VBoxManage` binary and add it to the PATH environmental variable.

Vagrant precisa un hipervisor. Pude ser Virtual Box u otro, pero lo necesita por debajo. Ver esto

No VirtualBox en ubuntu 23.10 ? Pues Mejor. Ver QEMU/KVM stack with Virt-manager as GUI

QEMU: quoting https://www.qemu.org/download/#linux

  • For full system emulation run: apt-get install qemu-system

  • For emulating Linux binaries run: apt-get install qemu-user-static

  • 3. inicio la máquina virtual --> vagrant up

  • 4. conexión a la máquina virtual--> vagrant ssh

  • 5. creo un holamundo en un editor de texto nano

sudo apt install qemu -> qemu-system qemu-kvm -> libvirt-daemon libvirt-daemon-system libvirt-clients bridge-utils
