+AWS_terraform_ansible_single_vyos_instance
+------------------------------------------
+
+How to create a single instance and install your configuration using Terraform+Ansible+AWS
+Step by step:
+
+AWS
+---
+
+1.1 Create an account with AWS and get your "access_key", "secret key"
+
+1.2 Create a key pair and download your .pem key
+
+1.3 Create a security group for the new VyOS instance
+
+Terraform
+---------
+
+2.1 Create a UNIX or Windows instance
+
+2.2 Download and install Terraform
+
+2.3 Create the folder for example ../awsvyos/
+
+2.4 Copy all files into your Terraform project (vyos.tf, var.tf)
+2.4.1 Please type the information into the strings 22, 35, 36 of file "vyos.tf"
+
+2.5 Type the commands :
+
+ #cd /your folder
+
+ #terraform init
+
+Ansible
+-------
+
+3.1 Create a UNIX instance
+
+3.2 Download and install Ansible
+
+3.3 Create the folder for example /root/aws/
+
+3.4 Copy all files from my folder /Ansible into your Ansible project (ansible.cfg, instance.yml, mykey.pem)
+
+mykey.pem you have to get using step 1.2
+
+Start
+-----
+
+4.1 Type the commands on your Terrafom instance:
+
+ #cd /your folder
+
+ #terraform plan
+
+ #terraform apply
+
+ #yes

+
+Terraform
+---------
+
+2.1 Create a UNIX or Windows instance
+
+2.2 Download and install Terraform
+
+2.3 Create the folder for example ../vsphere/
+
+2.4 Copy all files from my folder /Terraform into your Terraform project
+
+2.5 Type the commands :
+
+ #cd /your folder
