cakephp-app

This is a quickstart Dockerfile for deploying CakePHP in a Docker container, able to connect to a remote database, and inject ENV vars to configure your application.

Note: The CakePHP application is forked from here.

Based on Centos 7 and PHP 7.3

Note: This project is meant to be an example to study the basics and essentials of Kubernetes Operators using the Openshift platfrom with the CakePHP application in a Docker environment, therefore it is build on an Centos base image rather then a PHP base image.

Usage

To create the image quay.io/rocrisp/cakedemo, execute the following command on the cakephp-app directory: Note: Replace quay.io/rocrisp with your own registry.

docker build --no-cache -t quay.io/rocrisp/cakedemo:v1 .

Openshift Operator requires the image to pull from a registry. You can now push your new image to a registry:

docker push quay.io/rocrisp/cakedemo

Running your CakePHP docker image

1: Connecting to a MySQL container

Start a MySQL container

docker run -d \
	--name mysql-server \
	-e MYSQL_ROOT_PASSWORD=cakephp \
	-e MYSQL_DATABASE=cakephp \
	mysql:5.7

2: Running your CakePHP docker image and and link it to the MySQL container you just started.

docker run -d -p 80:8080 \
	--name cakephp \
	-e "DATABASE_URL=mysql://root:cakephp@mysql-server/cakephp?encoding=utf8&timezone=UTC&cacheMetadata=true" \
	-e "SESSION_DEFAULTS=database" \
	-e "DATABASE_NAME=cakephp" \
	-e "FIRST_LASTNAME=Rose Crisp" \
	--link mysql-server:mysql \
	quay.io/rocrisp/cakedemo:v1

Test your deployment

Visit http://localhost/ in your browser or

curl http://localhost/

You can now start using your CakePHP container!

Troubleshooting

If you get this error: Bind for 0.0.0.0:80 failed: port is already allocated.

docker ps -a | grep 80
docker rm -f <container id >
