## Instalando Terraform
2+
3+
La instalación de Terraform es un simple ejecutable que añadiremos a nuestro path. Podemos usar los gestores de paquetes de nuestro sistema operativo para instalarlo.
4+
5+
## Instalación Manual
6+
7+
Este paso es común a todos los sistemas operativos.
8+
9+
Descargar el paquete adecuado para nuestro sistema operativo en [este enlace](https://www.terraform.io/downloads).
10+
11+
### Instalación Manual Mac o Linux
12+
13+
Una vez descargado lo descomprimimos, y lo movemos al directorio de ejectutables.
14+
15+
```bash
16+
mv ~/Downloads/terraform /usr/local/bin/
17+
```
18+
19+
Para confirmar la instalación, simplemente ejecutar:
20+
21+
```bash
22+
terraform -help
23+
```
24+
25+
### Instalación Manual Windows
26+
27+
Una vez descargado lo descomprimimos y lo ubicamos en una carpeta fácilmente reconocible por ejemplo `C:\terraform`.
28+
29+
Para editar el `PATH`, seguiremos los siguientes pasos:
30+
31+
1. Ir a `Control panel` --> `System` --> `System settings` --> `Environment Variables`
32+
2. Buscar `PATH`
33+
3. Pulsar `edit` y modificarlo de forma adecuada
34+
4. Asegurar que hemos incluido `;` --> `c:\path;c:\path2`
35+
36+

# Introducción
2+
3+
## Infraestructura como código
4+
5+
> Proveer infraestructura a través del software para conseguir despliegues consistentes y predecibles.
6+
7+
## Conceptos fundamentales
8+
9+
* Definido en Código
10+
* Almacenamiento en control de versiones
11+
* Declarativo o imperativo
12+
* Idempotente y consistente
13+
* Push o Pull
14+
15+
## Declarativo vs Imperativo
16+
17+
```ini
18+
# Make me a campero
19+
get mollete
20+
get ham
21+
get cheese
22+
get tomato
23+
get lettuce
24+
get mayonnaise
25+
26+
put ham in mollete
27+
put cheese on ham
28+
put lettuce on cheese
29+
put tomato on lettuce
30+
```
31+
32+
```ini
33+
# Make me a campero
34+
get mollete
35+
get ham
36+
get cheese
37+
get tomato
38+
get lettuce
39+
get mayonnaise
40+
41+
put ham in mollete
42+
put cheese on ham
43+
put lettuce on cheese
44+
put tomato on lettuce
45+
put mayonaise on tomato
46+
```
47+
48+
```ini
49+
# Make me a campero
50+
food campero "classic-campero" {
51+
ingridients = [
52+
"ham", "cheese", "tomato", "lettuce", "mayonnaise"
53+
]
54+
}
55+
```
56+
put mayonaise on tomato
57+
```
58+
59+
```ini
60+
# Make me a campero
61+
food campero "classic-campero" {
62+
ingridients = [
63+
"ham", "cheese", "tomato", "lettuce", "mayonnaise"
64+
]
65+
}
66+
```
67+
68+
> Terraform es un ejemplo de aproximación declarativa para desarrollar Infraestructure as Code.
69+
70+
## Idempotente y Consistente
71+
72+
* Mi amigo: Hazme un Campero
73+
* Mi respuesta Toma tu Campero
74+
75+
En un mundo **idempotente**, si **mi amigo pregunta de nuevo** por el `campero`
76+
77+
* Mi amigo: Hazme un Campero
78+
* Mi respuesta Toma tu Campero
79+
80+
No te voy a hacer otro porque ya tienes uno.
81+
82+
> Terrafom intenta ser idempotente en el sentido de que si n has cambiado nada en tu código y lo aplicas de nuevo al mismo entorno, nada cambiará en el entorno porque tu código coincide con la realidad de la infraestructura que existe.
83+
84+
## Push or Pull
85+
86+
* ¿Pushing o Pulling al entorno?
87+
* Terraform es de tipo PUSH
88+
89+
## Beneficios de la Infraestructura como Código
90+
91+
* Despliegues automatizados
92+
* Proceso repetible
93+
* Entornos consistentes
94+
* Componentes reusables
95+
* Arquitectura documentada

# Desplegando la configuración base
2+
3+
## AWS account
4+
5+
Crear una nueva cuenta AWS
6+
7+
## Pasos
8+
9+
### Paso 1. Crear directory de trabajo
10+
11+
Creamos los nuevos drirectorios `lab/lc_web_app` y dentro añadimo el fichero `main.tf`
12+
13+
```bash
14+
mkdir -p lab/lc_web_app
15+
cp ./.start-app/main.tf ./lab/lc_web_app
16+
```
17+
18+
Cambiamos el directorio de trabajo a `lab/lc_web_app`
19+
20+
```bash
21+
cd ./lab/lc_web_app
22+
```
23+
24+
### Paso 2. Actualizamos las crednciales
25+
26+
Actualizar `access_key` y `secret_key`
27+
28+
```diff
29+
provider "aws" {
30+
+ access_key = "ACCESS_KEY"
31+
+ secret_key = "SECRET_KEY"
32+
region = "eu-west-3"
33+
}
34+
```
35+
36+
### Paso 3. Comenzar la inicialización
37+
38+
```bash
39+
terraform init
40+
```
41+
42+
Obtendremos un output similar a este:
43+
44+
```
45+
Initializing the backend...
46+
47+
Initializing provider plugins...
48+
- Finding latest version of hashicorp/aws...
49+
- Installing hashicorp/aws v3.70.0...
50+
- Installed hashicorp/aws v3.70.0 (signed by HashiCorp)
51+
52+
Terraform has created a lock file .terraform.lock.hcl to record the provider
53+
selections it made above. Include this file in your version control repository
54+
so that Terraform can guarantee to make the same selections by default when
55+
you run "terraform init" in the future.
56+
57+
Terraform has been successfully initialized!
58+
59+
You may now begin working with Terraform. Try running "terraform plan" to see
60+
any changes that are required for your infrastructure. All Terraform commands
61+
should now work.
62+
63+
If you ever set or change modules or backend configuration for Terraform,
64+
rerun this command to reinitialize your working directory. If you forget, other
65+
commands will detect it and remind you to do so if necessary.
66+
```
67+
68+
### Paso 4. Obtener un Plan
69+
70+
Ahora que nuestra configuración ha sido inicializada, podemos obtener un plan:
71+
72+
```bash
73+
terraform plan -out d1.tfplan
74+
```
75+
76+
> Con este comando, estamos indicando que queremos el `plan` volcado sobre el fichero `d1.tfpplan`
77+
78+
Terraform nos indica las acciones que va a relizar.
79+
80+
```
81+
Plan: 7 to add, 0 to change, 0 to destroy.
82+
83+
──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
84+
85+
Saved the plan to: d1.tfplan
86+
87+
To perform exactly these actions, run the following command to apply:
88+
terraform apply "d1.tfplan"
89+
90+
```
91+
92+
### Paso 5. Aplica el Plan
93+
94+
```bash
95+
terraform apply "d1.tfplan"
96+
```
97+
98+
Si aplicamos este comando, sin alimentar un plan, nos mostrarán un diálogo de confirmación de plan previo.
99+
100+
Después de unos minutos el despliegue finaliza, podemos acceder a la consola de AWS
101+
102+
## Clean Up
103+
104+
```bash
105+
terraform destroy
106+
```
