## Deploying Teleport on a Linux Ubuntu Server: A Step-by-Step Guide

Introduction:
Teleport is an open-source platform designed to secure and manage access to infrastructure. In this guide, we'll walk through the process of deploying Teleport on a Linux Ubuntu Server. By the end of this tutorial, you'll have a robust access management solution for your infrastructure.

Prerequisites:
Before we begin, make sure you have the following:

A Linux Ubuntu Server (18.04 LTS or later).
SSH access to your server with sudo privileges.
A domain or subdomain pointing to your server's IP address.
Step 1: Update and Upgrade Packages
Ensure that your server is up to date by running the following commands:

sudo apt update
sudo apt upgrade

Step 2: Install Docker and Docker Compose
Teleport relies on Docker, so let's install it along with Docker Compose:

sudo apt install docker.io docker-compose

Start and enable the Docker service:

sudo systemctl start docker
sudo systemctl enable docker

Step 3: Create Teleport Configuration
Create a directory to store your Teleport configuration:

sudo mkdir -p /etc/teleport

Now, create a teleport.yaml configuration file. You can use a text editor of your choice:

sudo nano /etc/teleport/teleport.yaml

Copy and paste the following example, replacing with your actual domain:

teleport:
  nodename: teleport-node
  data_dir: /var/lib/teleport
  ca_pin: ""
auth_service:
  enabled: "yes"
  listen_addr: 0.0.0.0:3025
  tokens: ["<your_secure_token>"]
  cluster_name: "<your_cluster_name>"
  authentication:
    oidc_connectors: []
ssh_service:
  enabled: "yes"
  listen_addr: 0.0.0.0:3022
  labels:
    env: "prod"
proxy_service:
  enabled: "yes"
  listen_addr: 0.0.0.0:3023
  web_listen_addr: 0.0.0.0:3080
  tunnel_listen_addr: 0.0.0.0:3024
  public_addr: "<your_domain>:3080"

Save and exit the text editor.

Step 4: Deploy Teleport
Use Docker Compose to deploy Teleport:

sudo docker-compose up -d

Teleport should now be running on your server.

Step 5: Access the Teleport Dashboard
Open your web browser and navigate to https://:3080. You'll be prompted to log in with the token specified in the configuration file.

Congratulations! You've successfully deployed Teleport on your Linux Ubuntu Server. This powerful tool provides secure access to your infrastructure, making it easier to manage and control user permissions.
