Setup Laravel with Docker containers

Docker

Docker has captured my attention lately and has been growing exponentially for last few years. Docker has revolutionized the virtualization space and has given DevOps engineers and developers a new set of tools that can ease their development as well as infrastructure resource utilization. Mostly Node.js apps have been deployed with Docker but it is not limited to only that. If you’ve been developing apps for web using PHP and Laravel framework then you are lucky that community has developed some great tools to utilize docker in their development workflow. If you are new to Docker and want to learn more about Docker then visit their website docker.com specially the section What is Docker?

Laradock

Laradock does the hard part and facilitate developers to quickly and easily setup Laravel development environment in seconds. Follow the these steps to get started.

Setup fresh environment then install Laravel inside docker

  • Create project directory. e.g. myproject
  • Create another directory within myproject directory for source that you will use commit to git repo. eg. app
  • Clone the laradock repo inside myproject folder, this will create laradock folder
git clone https://github.com/laradock/laradock.git
  • Edit the docker-compose.yml file to map to your project directory once you have it (eg. – ../app:/var/www)
  • Run the following command
docker-compose up -d nginx mysql redis beanstalkd
  • Enter the workspace
docker-compose exec workspace bash
  • cd to /var
  • Install Laravel
composer create-project laravel/laravel www
  • Open your .env file and set the following
DB_HOST=mysql
REDIS_HOST=redis
QUEUE_HOST=beanstalkd

Now open your browser and visit http://localhost

You will see running Laravel app. That was cool!

You can also connect to mysql using these settings.

Host: localhost
User: root
Password: root

If you want to add more services see the official laradock docs. It support tons of other services like memcache, pgsql etc.

Daily Use

Following are some docker related commands that you want to use on daily basis once your development environment is setup.

  • To bring up the servers to run application
docker-compose up -d nginx mysql
  • Enter workspace container to run commands like artisan, composer, phpunit, gulp etc.
docker-compose exec workspace bash

or on Windows PowerShell

docker exec -it {containerid} bash
  • List current running containers
docker ps
  • List current project containers
docker-compose ps
  • Close all running containers
docker-compose stop
  • Delete all existing containers
docker-compose down
  • View the log files
docker logs {container-name}

 

 

How to use wildcard domain with OpenShift hosting?

If you have a domain name and want to use OpenShift for hosting then using wildcard domain name is bit tricky with some domain registrars like GoDaddy. The reason is IP address of app on OpenShift doesn’t remain same and to use wildcard domain a DNS A record is setup with the IP address of hosting server. So, how do we make sure following to be true:

That is, the www prefix is always displayed anywhere on the site.

But due to the non-static IP of OpenShift app it is not possible to adjust the A record. But you can set up a cname with the following:

www > appname-username.rhcloud.com

where the format for the OpenShift app is

http://appname-username.rhcloud.com.

This means the site is accessible at http://www.mysitename.com but not at mysitename.com. To make it work you need to do the following.

On domain registrar like GoDaddy
– Create new Record with
Record Type CNAME
HOST: www
POINT TO: appname-username.rhcloud.com

On Openshift
1. Select Application tab > select application appname-username.rhcloud.com > click change
2. Enter Domain name http://www.mysitename.com

That’s it! Wait for 10-15 min and see the magic.
