AWS ALB
2+
==============
3+
4+
This module is for create alb with related resources.
5+
6+
###### main.tf
7+
contain resource code for alb.
8+
9+
###### variables.tf
10+
contain variables declaration. all variables are empty by default. we will define or put value to variables in equls.tf (main file for infrastructure). these are input vars.
11+
12+
###### outputs.tf
13+
is alse contain variables but we will these variables for output like ec2 instance id.
14+
15+
## Infrastructure creats by this module
16+
17+
1. Alb
18+
2. Alb listener
19+
3. Alb target group
20+
4. Alb target group attachment.
