Requirements

• Terraform installed (Version used: v0.13.0)
• Ansible installed (Version used: 2.9.12)
• SSH private and public keys
• Google Cloud Platform or Digital Ocean account.

Usage

• Clone the repository

git clone –depth 1 https://github.com/aaaguirrep/offensive-docker-vps.git vps
cd vps

• Credentials
  • Create credentials folder. mkdir credentials

• For Google Cloud Platform
  • Create a new project.
  • Create service account with “Compute Admin” role and download a key in json format in credentials folder.
  • Rename the key to gcp.json
  • Enable “Compute Engine API” for the project.

• For Digital Ocean
• Create a Personal access tokens with write permission and copy it. See Tutorial
• SSH Private and Public keys
• Inside credentials folder run ssh-keygen -t rsa -f offensive in the terminal. Empty passphrase is ok.
• It creates two files: private and public key.

• Terraform

• Google Cloud Platform
  • Enter to gcp folder and modify the next value:
    • In main.tf file change the project value with your project-id.
    • Run the next commands:

# Initialize terraform provider
$ terraform init
Terraform has been successfully initialized!

# Create the resources
$ terraform apply -auto-approve
Apply complete! Resources: 3 added, 0 changed, 0 destroyed.
Outputs:
external_ip = x.x.x.x

• Copy the external_ip value

Note: The instance type and the region used are: n1-standard-1 and us-central1. You can change the values on server.tf and main.tf

Demo

Digital Ocean

• Enter to digital-ocean folder
• With the personal access token copied run export TF_VAR_do_token="Personal_Access_Token_Here"
• Run the next commands:

# Initialize terraform provider
$ terraform init
Terraform has been successfully initialized!

# Create the resources
$ terraform apply -auto-approve
Apply complete! Resources: 3 added, 0 changed, 0 destroyed.
Outputs:
external_ip = x.x.x.x

• Copy the external_ip value

Demo

Ansible

• Enter to ansible folder
• In hosts.yaml change the x.x.x.x by external_ip value copied.
• Run the next command:

$ ansible-playbook playbook.yaml
TASK [Configuration finished] *******************************************************
ok: [x.x.x.x] => { “msg”: “System configured correctly.”
}

Demo

Access to VPS

• In gcp or digital-ocean folder run the next command. Change x.x.x.x by external_ip value copied.

# Access to VPS
$ ssh offensive@x.x.x.x -i ../credentials/offensive

Demo

Destroy the VPS

• In gcp or digital-ocean folder run the next command.

# Destroy the resource
$ terraform destroy -auto-approve

Note: For Digital Ocean, if you dont have a default VPC created in the region used it shows an error to destroy the VPC but no problem, it will destroy the others resources.
