Node.js on DigitalOcean with Ansible
Complete playbook to create and deploy a Node.js application on Digital Ocean.
I wanted to:
- Automate build and configuration of a droplet
- Automate deployments of my project
Many thanks to https://github.com/yoshz/ansible-digitalocean cause I took a lot of his code.
This script will:
- Generate an SSH key on the local machine if it doesn't exist
- Create a droplet with the SSH key
- Add a domain and point it to the droplet
- Add swapfile to droplet
- Add a new root-user to the droplet and enable sudo
- Secure with ufw and restrict SSH to pub-key access only
- Setup Papertrail logging
- Add nginx as a reverse proxy
- Request a certificate from LetsEncrypt
How to use it
You need Ansible to start with this project. So go get it!
- Clone this repo
tasks/project.ymland add your own rules
Make sure to add the
deploy tags (or any other you need) to your own tasks.
ansible-playbook main.yml --tags=launch to launch the server
ansible-playbook main.yml or
ansible-playbook main.yml --tags=launch
for the initial setup. Make sure that you've obtained your domain and already pointed to DigitalOcean's nameservers. It's better to wait a few hours for the changes to be propagated.
ansible-playbook main.yml --tags=deploy
to deploy your app. Make sure to add the apropriate tags in tasks/project.yml when adding your custom tasks.
ansible-playbook main.yml --tags=certificate
to renew the certificate.
The main entrypoint is the main.yml file. The playbook is divided in three plays one for the DigitalOcean configuration, one for the server initial configuration which runs as root user and the third for the specific project configuration.
The tasks folder contains all tasks required by the playbook. It's file is named after it's concern so it's easy to spot where something is happening.
You can place your project's specific files at the files folder.
Tweak the project using the defaults/vars.yml file. All of the values there are required, so make sure that are valid and cover your needs.
The main file you need to edit is the tasks/project.yml. This file is called after the server is up and running. The example file will:
- Pull your repo (http://docs.ansible.com/ansible/git_module.html) only if it has changes to pull
- install local dependecies (http://docs.ansible.com/ansible/npm_module.html)
- install global dependecies like
- build your repo using
- start it using
