Krishnan's Personal Website

This blog and website is built on PhalconPHP and to initially set it up I had to run multiple configurations to get it up and running on my localhost as well as on my server. This was complicated to start with and imagine if I’m trying out multiple frameworks from different languages then making specific configurations for each one of them would become a nightmare.

So I decided to give Docker a try.

To start with I watched the following Docker tutorial on Youtube. It was wonderful and gave me exactly what I wanted (which was to learn Docker from a developer’s perspective).

Once I understood the basic concepts of Docker, I installed Docker on my computer.

After that I googled for a PhalconPHP docker image that I could use as a starting point. My search landed me to the following medium article which explained setting up PhalconPHP Docker containers. I simply followed the article.

Working with Phalcon Framework and Docker

Once I had Phalcon application setup I closed the containers.

$ docker-compose down

I use mysql with this website and hence needed a volume to store the database.

$ docker volume create --name=volumename

To confirm if the volume got created.

$ docker volume ls

Then I opened docker-compose.yml and made the following changes.

version: '3'
services:
 app:
  container_name: app
  build: .
  working_dir: /var/www/html
  volumes:
   - ./:/var/www/html
  ports:
   - '5000:80' {port of my choice}
  expose:
   - '5000'

 mysql:
  image: mysql:8
  container_name: app-db
  volumes:
   - volumename:/var/lib/mysql #Added volumes for persistent data storage
  environment:
   MYSQL_ROOT_PASSWORD: root
   MYSQL_DATABASE: {DB Name}
   ports:
    - '3307:3306' {port of my choice}
  environment:
   - ALLOW_EMPTY_PASSWORD=yes

volumes:
 volumename:


I saved the file and created Docker containers again.

$ docker-compose up -d

I checked to see if the docker containers got created,

$ docker ps

The containers should get created with the container name that you chose in the docker-compose.yml file.

I could login into the containers by typing,

$ docker exec -it app /bin/bash

$ docker exec -it app-db /bin/bash

This should setup PhalconPHP in Docker containers and you can now easily bring in your old applications or start building something new.
