Docker and Laravel

Storyline

I will never learn all the technologies and The technology always is changing,then I thought I must choose which I like and to do this my backbone, I would have a basic platform for deal with it, good and reliable tools.

On a project I has a problem is created thinking in windows and all would be so easy and save a lot of time if I had chosen windows but I love Archlinux and Neovim, use the terminal (sigh cheesy), and wherever it can be my future like programmer I want to be a master with this tools.

Archlinux is wonderful the documentation is excellent and install a software is easy peasy has a strong community beautiful always update .. and yes always update, this was my problem one day I use php 5.x BOOM! now I have php 7.0 great but the project does not use 7.0 and although it is possible control which package is updating I don't want always take care about it.

Laravel has homestead then vegrant was my first option I was learning but I found a compatibility problems between vagrant and virtualbox I needed downgrade my vegrant, the case it the same I don't want deal with this then I tried docker.

Docker

Docker has IMAGES and CONTAINERS

1. IMAGES is your base like a image of Ubuntu or Fedora etc.
2. CONTAINERS is the place where you can play do everything you want experiment.
3. Host is your computer.

Everytime you run an image this will become container this mean you can run 5 times ubuntu and in an instant, really! in an instant you have 5 different places where you can play delete/install everything you want, it does not work throw it in trash (delete your container) and run ubuntu (image) one more time, beautiful no?.

Docker has 2 options to custom your cointaner

1. Dockerfile: it is a file where you write every instruction, build this file and SHAZAM! you have your environment.
   write your file DOCKERFILE => BUILD => a new IMAGE
2. run your image install everything you want and commit the changes. UBUNTU => CONTAINER UBUNTU (configure your environment) => commit => a new IMAGE

I chose the number 2 because I feel control everything I do, sometimes I feel so stupid, understand this take me a lot of time in essence is an easy concept, well let's continue.

Using Docker and Laravel

The fact is simple, I need other environment (SO) but I want to use my neovim I want this.

1. Laravel and Mysql in container.
2. I saw vagrant can communicate the files in the same directory...of course I want it.
3. Mysql workbreach and Neovim in host (neovim not within of a container because I don't want stay setting every container, in my life, take time and space).

let's go

Installation

sudo pacman -S docker sshfs 
docker pull ubuntu:14.04
docker images (you can see ubuntu)
docker run -it --name NAMECONTAINER -p 8090:8000 -p 8050:22 -p 3308:3306 ubuntu:14.04 bash

Considerations

1. user/nameproject is the convection name but I prefer nameprojectc, in the end a c only indicates the name and c of container because is a short name.
2. You can choose every port you want: -p HOST:CONTAINER
3. Command exit stop and exit your container
4. ctrl+p ctrl+q go to host but doesn't stop your container.
5. PROMPTHOST > docker attach NAMECONTAINER return to CONTAINERPROMPT but if it does not appear, press ctrl+c
6. PROMPTHOST > docker inspect NAMECONTAINER show you gateway= IP host and IPAddress = IP cointainer

Now, in the prompt of the container

apt-get update
apt-get -y install vim openssh-server git curl
apt-get -y install mysql-server libapache2-mod-auth-mysql php5-mysql
apt-get -y install php5  php5-mcrypt php5-cli 
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Edit /etc/php5/cli/php.ini search the section of mcrypt and adds extesion=mcrypt.so

Create your project laravel, I am in /home.

composer create-project laravel/laravel HelloDocker "~5.0.0" --prefer-dist
cd /home/HelloDocker
php artisan serve --host=0.0.0.0 --port=8090

go to your browser IPCONTAINER:8090, great! you can see the website.

Mysql

Comment this line in /etc/mysql/my.cf
bind-address = 127.0.0.1

PROMPTCONTAINER > service mysql start

on mysql run

GRANT ALL PRIVILEGES ON * . * TO 'USER'@'IPGATEWAY';
FLUSH PRIVILEGES;

on mysql workbreanch, create a new connection, hostname: GATEWAY and port:3308; Do you remember? we used -p 3308:3306

as said steve jobs, one more thing

SSHFS

San wikipedia:
SSHFS (SSH Filesystem) is a filesystem client to mount and interact with directories and files located on a remote server or workstation over a normal ssh connection

PROMPTCONTAINER >

mkdir /var/run/sshd
echo 'root:screencast' | chpasswd
sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
ssh-keygen
/usr/sbin/sshd -D &

PROMPTHOST>

sshfs root@HostIp:/path/to/project /path/to/directory/to/mount/ -p 8050
# password is screencast
cd /path/to/directory/mounted

Everything is ready, there is the laravel project.

if you want to save your container like a image
PROMPTHOST> docker commit NAMECONTAINER NEWNAMEIMAGE
PROMPTHOST> docker images

Tl;dr

Docker rocks
