Prepare Linux Instances for Provider Installation

This guide will walk you through setting up and deploying a provider using Ansible. The steps cover installation on a local system, configuring a remote server, and managing deployments. This document provides best practices and recommendations for doing so.

Pre Requisites

• A Linux server with Ubuntu 22.04.
• Ansible installed on your local machine.
• Basic knowledge of server administration, Ansible, and Kubernetes.

To install Ansible on a Mac, you can use various methods such as Homebrew, pip, or by installing it from source. Here are the steps for each method:

1. Setup Ansible Using Homebrew

Install Homebrew

If you haven't installed Homebrew yet, open Terminal and run:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Ansible

Once Homebrew is installed, run:

brew install ansible

Alternatively, if you have Python installed, you can use:

pip install ansible

For other distributions, refer to the Ansible Community Documentation (opens in a new tab) for specific installation instructions.

Verify the Installation

Check the version of Ansible to confirm it's installed:

ansible --version

2. Setup Domain for the Provider

Create the following name entries on your domain provider.

This is the records you need to put for your domain - yourdomain.com

3. Firewall & Port Policy for Master node

To ensure the master node on your provider functions correctly, you must expose specific TCP ports on your server. The required configuration includes:

1. TCP Ports Range: Open all TCP ports from 1000 to 65535. This wide range ensures that all necessary communications and services can operate without restriction.
2. Standard Web Ports:
   • Port 80: This port is typically used for HTTP traffic, allowing web services to be accessible over the internet.
   • Port 443: This port is used for HTTPS traffic, ensuring secure, encrypted communications for web services.

By exposing these ports to the internet, you enable the master node to interact with various components and services, ensuring seamless operation and connectivity.

Steps to Expose Ports

1. Firewall Configuration: Adjust your firewall settings to allow inbound and outbound traffic on the specified ports.
2. Network Settings: Ensure that your network configuration (e.g., router, security groups) permits traffic on these ports.
3. Server Security: Regularly monitor and secure these ports to protect against unauthorized access and potential vulnerabilities.

Following these steps will help maintain the proper functionality and security of your master node on the provider.

4. Prepare Linux Instance for Installation Using Ansible

Step 1: Clone the Repository

Clone this repo onto your local system: GitHub - spheronFdn/provider-deployment (opens in a new tab)

git clone https://github.com/spheronFdn/provider-deployment

Repo has the following file structure:

Step 2: Edit Inventory File

Now, edit the playbook/inventory.ini file with your server details, Example:

[testnet] 
server-name ansible_host=23.158.40.38 ansible_user=root ansible_ssh_private_key_file=~/.ssh/id_rsa

Step 3: Edit Playbook

Now edit the hostname in playbook/playbook.yaml

hostname: provider.example.com        ## this can be your registered domain name that will be used for the provider

Step 4: Execute the Playbook

Now execute the playbook

cd playbook
ansible-playbook -i inventory.ini playbook.yml

After the whole execution, the server will restart.
