Nodemation on DigitalOcean with Ansible

Complete ansible playbook to provision and deploy nodemation to a Digital Ocean droplet.

Intro

This project created to be a one step playbook to deploy new nodemation instances to DigitalOcean using Ansible.

I wanted to:

• Provision the droplet with a configurable admin user

• Manage fetching an SSL Certificate from Lets Encrypt
• Configure Nginx to pass the n8n application to the https://

How to setup the project

You need Ansible to start with this project. So go get it! I used ansible 2.9.10 for the project.

• Clone this repo into a folder on your computer:

git clone https://github.com/johnkraczek/n8n-ansible-install.git

• Edit group_vars/n8n/vars.yml with your values, Specifically update:

  • system_user:
  • lets_encrypt_email:
  • domain:

• Edit hosts and insert the IP address of your newly minted Digital Ocean Droplet (Ubuntu 22.04.3 LTS x64)

  • Don't have a Digital Ocean Acccount yet? Get One Here use my link to get $100 off for the first 60 days.

• Point the domain you added to group_vars/n8n/vars.yml to the IP address you added to the hosts file. [Cloudflare DNS] (https://dash.cloudflare.com/) Note: you will need to have cloudflare NOT proxy the domain (Orange Cloud => Grey Cloud).

Run ansible-galaxy install -r requirements.yml to install the galaxy roles used by the playbook.

Provision the server:

ansible-playbook main.yml
