Simple Ansible Playbook: Configure and Run Go Web Server

Overview

This Ansible playbook automates the deployment and configuration of a Go web server on remote servers. It performs tasks such as creating directories, copying files, and configuring services to set up a functional Go web application.

Prerequisites

• Ansible installed on the control machine.
• Access to remote servers via SSH.
• Proper SSH credentials (e.g., private key) for connecting to remote servers.

Usage

1. Clone this repository:

   git clone https://github.com/your-username/your-repo.git
   cd your-repo

2. Update the Ansible inventory (hosts file) with your server details:

   [web_servers]
   server1 ansible_user=your-ssh-user ansible_ssh_private_key_file=your-ssh-key.pem

3. Modify playbook variables and configurations (if needed) in playbook.yaml.

4. Run the Ansible playbook:

   ansible-playbook -i hosts playbook.yaml

Playbook Structure

1. Create Destination Directory: Ensure the existence of the /home/app-ansible directory.
2. Remove Existing goapp File: Delete any existing goapp file in /home/app-ansible.
3. Copy New Binary File: Copy the latest binary file to /home/app-ansible/goapp.
4. Copy Nginx Configuration: Place the go.conf Nginx configuration file in /etc/nginx/conf.d/.
5. Reload systemd (daemon-reload): Execute systemctl daemon-reload to reload systemd configurations.
6. Reload Nginx: Restart the Nginx service to apply the new configuration.
7. Configure systemd Service: Use a template to configure the goapp systemd service.
8. Restart goapp Service: Restart the goapp service using sudo service goapp restart.

Notes

• This playbook assumes the target servers are running systemd and Nginx.
• Customize the playbook according to your specific environment and requirements.
