How to deploy a dockerized php application

I have a Laravel application and docker setup for local development using docker-compose. My source code for the application is kept in BitBucket and now I would like to deploy the application to a Linode instance and serve it from the docker system. How this can be done ? As of now I have a LAMPP image running in Linode and I push my source code to the corresponding path when deployment is triggered. Now I would like to use the same docker image in the server instead of the LAMPP server I am using. How this can be done ? Or this is the correct method of doing it ?

It will be helpful if someone can point out a tutorial or guide for doing this ?

Solution

If you are locked on staying with linode, I would try one of these options:

Linode docker machine driver - note that this is a non official docker machine driver.
Linode containers guide - using Kubernetes, which I usually try to avoid for my small-scale apps.

If you are NOT locked on staying with linode, and you wish to avoid the complexities of Kubernetes, I can tell you I have had success with running a docker machine on Digital Ocean - this solution (as most other docker-machine solutions) makes deployment as easy as running it locally.

As for how to get your code PHP code to the container, here is an example Dockerfile I have been using for one of my PHP dockerized apps:

FROM php:7-apache

# Packages
RUN apt-get -y update && apt-get -y install git zip
RUN a2enmod rewrite && docker-php-ext-install sockets

# App
COPY . .

# Composer
COPY private/composer.phar /usr/local/bin/composer
RUN chmod +x /usr/local/bin/composer
RUN [[ ! -f composer.json ]] || composer install --ansi --no-interaction

You can adjust it to your needs.
