shinsenter/codeigniter4 repository overview

⁠shinsenter/codeigniter4

🔋 (PHP / CodeIgniter) Production-ready Docker images with automatic CodeIgniter installer.

• Docker Hub: https://hub.docker.com/r/shinsenter/codeigniter4⁠
• GitHub Packages: https://code.shin.company/php/pkgs/container/codeigniter4⁠
• You can also find and use other pre-built Docker images for some popular PHP applications and frameworks here⁠.

The Docker images are available for both Debian and Alpine versions.

⁠Introduction

Our PHP Docker images, available on Docker Hub⁠, are designed for easy configuration of PHP and PHP-FPM settings via environment variables. This approach eliminates the need to rebuild images when making configuration changes.

These images also come with the latest version of Composer⁠, enabling you to start projects quickly without additional installations.

⁠Usage

Check out our documentation⁠ to learn how to customize these Docker images for your projects.

⁠Creating a New Project

When you mount an empty directory into the container, it will automatically download the entire source code for the framework, allowing you to bootstrap a new project quickly.

⁠Steps to Create a New Project

1. Create an empty directory on your host machine for your project code. For example:

mkdir codeigniter4

1. Run the container and mount the empty directory as a volume. For example:

docker run -p 80:80 -p 443:443 -p 443:443/udp \
    -v ./codeigniter4:/var/www/html \
    shinsenter/codeigniter4:latest

The container will detect the empty directory mounted to /var/www/html and clone the framework source code into it.

⁠Using an Existing Project

You can mount your application code from your host machine to the /var/www/html directory inside the container.

Because the source code is mounted as a volume, any changes made on the host machine will be reflected inside the container. This setup allows you to run builds, tests, and other tasks within the container while keeping your code on the host.

⁠Using HTTPS

The Docker images come with pre-generated SSL certificate files for testing HTTPS locally:

• /etc/ssl/site/server.crt
• /etc/ssl/site/server.key

To use valid HTTPS certificates for your production website, replace these files with your own valid SSL certificates. You can do this by copying or mounting your certificates from the host machine into the container. Simply overwrite the default certificate files with your valid certificate and key files to enable true HTTPS for your production website.

⁠Using Dockerfile

FROM shinsenter/codeigniter4:latest

# Copy your own certs into the container
COPY my_domain.crt /etc/ssl/site/server.crt
COPY my_domain.key /etc/ssl/site/server.key

# Add your instructions here
# For example:
# ADD --chown=$APP_USER:$APP_GROUP ./codeigniter4/ /var/www/html/

⁠Using docker run

docker run -p 80:80 -p 443:443 -p 443:443/udp \
    -v ./codeigniter4:/var/www/html \
    -v ./my_domain.crt:/etc/ssl/site/server.crt \
    -v ./my_domain.key:/etc/ssl/site/server.key \
    shinsenter/codeigniter4:latest

⁠Using docker-compose

services:
  web:
    image: shinsenter/codeigniter4:latest
    volumes:
      - ./codeigniter4:/var/www/html
      - ./my_domain.crt:/etc/ssl/site/server.crt
      - ./my_domain.key:/etc/ssl/site/server.key

⁠Stable Image Tags

The release versions on this GitHub repository⁠ don't guarantee that Docker images built from the same source code will always be identical.

We build new Docker images daily to ensure they stay up-to-date with the latest upstream updates for PHP, base OS, Composer, etc. The images in this repo are regularly updated under the same tag names.

But you can pull the image from shinsenter/codeigniter4:latest, and tag it with a name that indicates its stability, such as your-repo/codeigniter4:stable using the below commands:

docker pull shinsenter/codeigniter4:latest
docker tag  shinsenter/codeigniter4:latest your-repo/codeigniter4:stable
docker push your-repo/codeigniter4:stable

Then use the image your-repo/codeigniter4:stable as a base image to build containers for production.
