Update the article Terraform

Update to the article about terraform. I made changes to the structure and divided the article into three parts AWS AZ vSPhere. Made changes to the table of contents of the article. Added links to resources in git. Added troubleshooting as well as a detailed description of the files.

+Terraform for VyOS
+==================
+
+VyOS supports development infrastructure via Terraform and provisioning via Ansible.
+Terraform allows you to automate the process of deploying instances on many cloud and virtual platforms. 
+In this article, we will look at using terraforms to deploy vyos on platforms - AWS, AZURE, and vSphere.
+More detailed about what is Terraform you can write using the link_.
+
+Need to install_ Terraform
+
+Structure of files in the standard Terraform project:
+
+.. code-block:: none
+
+ .
+ ├── main.tf             # The main script
+ ├── version.tf          # File for the changing version of Terraform.
+ ├── variables.tf        # The file of all variables in "main.tf"
+ └── terraform.tfvars    # The value of all variables (passwords, login, ip adresses and so on)
+
+
+General commands that we will use for running Terraform scripts
+
+
+.. code-block:: none
+
+  #cd /<your folder>         # go to the Terrafom project
+  #terraform init          # install all addons and provider (aws az and so on)
+  #terraform plan          # show wtah is changing
+  #terraform apply         # run script
+  #yes                     # apply running
+
+
+Deploying vyos in the AWS cloud
+-------------------------------
+With the help of terraforms, you can quickly deploy Vyos-based infrastructure in the AWS cloud. If necessary, the infrastructure can be removed using terraform.
+Also we will make provisioning using Ansible.
+
+
+.. image:: /_static/images/aws.png

+   :alt: Network Topology Diagram
+
+In this case, we'll create the necessary files for Terraform and Ansible next using Terraform we'll create a single instance on the AWS cloud and make provisioning using Ansible.
+
+
+Preparation steps for deploying VyOS on AWS 
+-------------------------------------------
+
+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
+
+.. image:: /_static/images/keypairs.png
+   :width: 50%
+   :align: center
+   :alt: Network Topology Diagram
+
+1.3 Create a security group_ for the new VyOS instance and open all traffic

+   :alt: Network Topology Diagram
+
+Terraform
+
+
+2.1 Create a0 UNIX or Windows instance
+
+2.2 Download and install Terraform
+
+2.3 Create the folder for example /root/awsterraform
+
+.. code-block:: none
+
+ mkdir /root/awsterraform
+
+2.4 Copy all files into your Terraform project "/root/awsterraform" (vyos.tf, var.tf, terraform.tfvars,version.tf), more detailed see `Structure of files Terrafom for AWS`_
+
+2.5 Type the commands :
+
+.. code-block:: none
+
+   #cd /<your folder> 
+   #terraform init
+
+
+Ansible
+
+
+3.1 Create a UNIX instance whenever you want (local, cloud, and so on)
+
+3.2 Download and install Ansible
+
+3.3 Create the folder for example /root/aws/
+
+3.4 Copy all files into your Ansible project "/root/aws/" (ansible.cfg, instance.yml, mykey.pem and "all"), more detailed see `Structure of files Ansible for AWS`_
+
+mykey.pem you have to get using step 1.2
+
+
+Start 
+
+
+4.1 Type the commands on your Terrafom instance:
+   
+.. code-block:: none
+
+   #cd /<your folder>
+   #terraform plan  
+   #terraform apply  
+   #yes
+
+
+Start creating an AWS instance and check the result

+After executing all the commands you will have your VyOS instance on the AWS cloud with your configuration, it's a very convenient desition.
+If you need to delete the instance please type the command:
+
+.. code-block:: none
+
+   #terraform destroy
+
+
+Troubleshooting
+---------------
+
+1. Ansible doesn't connect via SSH to your AWS instance: you have to check that your SSH key has copied into the path /root/aws/.
+Also, increase the time in the file instance.yml from 300 sec to 500 sec or more. (It depends on your location).
+Make sure that you have opened access to the instance in the security group.
+
+2. Terraform doesn't connect via SSH to your Ansible instance: you have to check the correct login and password in the part of the file vyos. tf
+
+.. code-block:: none
+
+  connection {
+   type     = "ssh"  
+   user     = "root"              # open root access using login and password on your Ansible
+   password = var.password        # check password in the file terraform.tfvars isn't empty
+       host = var.host            # check the correct IP address of your Ansible host
+  }
+
+
+Make sure that Ansible is pinging from Terrafom.

-Deploying vyos in the AWS cloud

-With the help of terraforms, you can quickly deploy Vyos-based infrastructure in the AWS cloud. If necessary, the infrastructure can be removed using terraform.
-Also we will make provisioning using Ansible.

-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

---------------------------------------------
-
-How to create a single instance and install your configuration using Terraform+Ansible+Azure 
-Step by step:
-
-Azure
------
-
-1.1 Create an account with Azure
-
-Terraform
----------
-
-2.1 Create a UNIX or Windows instance
-
-2.2 Download and install Terraform
-
-2.3 Create the folder for example ../azvyos/
-
-2.4 Copy all files from my folder /Terraform into your Terraform project (main.tf, variables.tf)
-
-2.5 Login with Azure  using the command 
-
-  #az login
-
-2.6 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/az/
-
-3.4 Copy all files from my folder /Ansible into your Ansible project (ansible.cfg, instance.yml and /group_vars)
-
-Start 
------
-
-4.1 Type the commands on your Terrafom instance:
-   
-   #cd /your folder 
-
-   #terraform plan  
-
-   #terraform apply  
-   
-   #yes
-
