> El entorno está preparado para funcionar tanto en docker(Recomendado) en local o con una maquina virtual vagrant
9+
## Versiones de software
10+
- Vagrant: >= 2.2.x
11+
- Docker Engine: >= 19
12+
- [Docker Compose >= 1.27.4](https://docs.docker.com/compose/install/)
13+
- VirtualBox >= 6.x
14+
15+
## Creación del entorno
16+
1. Permitimos registry inseguro a docker
17+
* En Linux En el fichero /etc/docker/daemon.json
18+
```
19+
{"insecure-registries" : ["gitlab.local:5001"]}
20+
```
21+
* En windows lo hacemos via Docker Desktop
22+
23+
2a. Preparando el entorno con docker(Linux y windows).
24+
>> Es necesario permisos sudo (Linux) o Administrador(Windows)
25+
```bash
26+
user@localhost:~$ cd 02-gitlab/gitlab/docker/
27+
user@localhost:~02-gitlab/$ sudo chmod +x build_gitlab_docker.sh && sudo ./build_gitlab_docker.sh
28+
```
29+
2b. Preparando el entorno con Vagrant y Virtualbox
30+
```bash
31+
user@localhost:~$ cd 02-gitlab/
32+
user@localhost:~02-gitlab/$ sudo vagrant up
33+
```
34+
3. Añadimos entrada al fichero hosts la entrada -> <Direccion_ip_local> gitlab.local
35+
* Linux en el fichero /etc/hosts
36+
* Windows en el fichero c:\windows\system32\drivers\etc\hosts
37+
