LEMP Stack Dockerized Example

Description:

This project is a full LEMP stack example that is dockerized. It consists of a basic bootstrap + jQUery front-end which communicates with the simple PHP endpoints via AJAX. The PHP endpoints then access a MySQL database which exists locally. The entire project is dockerized for both local development through local file mounting and for more robust vps deployment. The web-app can actually be somewhat useful: I utilize a personal deployment of this project to keep track of errands :)

Local Usage:

Local testing is facilitated through file mounting, allowing for faster development:

• Make sure that docker and docker-compose are installed
• make run handles everything involved in installing, building and running the server in the background: access the server locally on: http://localhost:8080
• Remember to stop the server when you're finished: make stop
• You can reset the database with make reset; otherwise changes made to the website are persistent across uses

Deployment:

Deployment to DigitalOcean is quite simple with the following steps:

1. Create a DigitalOcean account and a personal access token through their API tab
2. Install docker-machine if necessary
3. Create a new droplet configured for docker: docker-machine create --driver digitalocean --digitalocean-access-token PERSONAL_ACCESS_TOKEN DROPLET_NAME
4. Use the newly created machine: eval $(docker-machine env temp)
5. Build the containers on the remote droplet: make deploy
6. Stop the containers using make stop and reset the database using make reset
7. Stop using the machine and return to the local environment: eval $(docker-machine env -u)
8. Destroy the droplet using docker-machine rm DROPLET_NAME (be careful)
