Introduction

This project contains Dockerfiles that power apporz.com -- my personal website. I want to share my ideas and designs about Web-Deploying using Docker with you.

Structure

The whole app is divided into four Containers:

1. Nginx is running in Nginx Container. Recieves requests from Clients then respond.
2. My App business-logic code and scripts is located at WWW Container. It just stores php scripts and static files.
3. PHP or PHP-FPM is put in PHP-FPM Container, it fetches php scripts from WWW then interpretes and executes them, making response to Nginx Server. If necessary, it will connect to MySQL server as well.
4. Considering the flexibility and security, MySQL server must be independent of other containers.

Build and Run

Build Images

At first, you should have had Docker installed.

# Add https(SSL) support 
# before build the Nginx Image , you should put your server.crt(or server.pem) , server.key to ./ca folder 

# build Nginx Image
$ sudo docker build --tag sndnvaps/nginx -f nginx/Dockerfile .

# build PHP-FPM Image
$ sudo docker build --tag sndnvaps/php-fpm -f php-fpm/Dockerfile .

# build WWW Image
$ sudo docker build --tag sndnvaps/www -f www/Dockerfile .

# pull MySQL Official Image
$ sudo docker pull mysql:latest

Run Containers

You must run the contaners in the following sequence:

1. MySQL Container
2. WWW Container
3. PHP-FPM Container
4. Nginx Container

The first two of which can be exchanged.

# Run MySQL Container

Mounting the database file volume

In order to persist the database data, you can mount a local folder from the host on the container to store the database files. To do so:

docker run -d -p 5003:3306 --name mysql_datavolume  -v /path/in/host:/var/lib/mysql -e MYSQL_ROOT_PASSWORD="you_password_here" -d  mysql /bin/bash -c "/usr/sbin/mysqld --initialize --user=mysql"

This will mount the local folder /path/in/host inside the docker in /var/lib/mysql (where MySQL will store the database files by default). mysqld --initialize --user=mysql creates the initial database structure.

Remember that this will mean that your host must have /path/in/host available when you run your docker image!

After this you can start your MySQL image, but this time using /path/in/host as the database folder:

# not mount the data_volume from host 

$ sudo docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql

# see https://github.com/docker-library/docs/tree/master/mysql

# Run WWW Container
# enable sshd for ssh connect
# connect ->$ ssh admin@localhost -p 5001 
$ sudo docker run --name www -p 5001:22 -d sndnvaps/www

# Run PHP-FPM Container
$ sudo docker run --name php-fpm --volumes-from www --link mysql:mysql -d sndnvaps/php-fpm
# see https://github.com/docker-library/docs/tree/master/php

# Run Nginx Container
# enable sshd for ssh connect
# connect ->$ ssh admin@localhost -p 5002
$ sudo docker run --name nginx -p 80:80 -p 443:443 -p 5002:22 --volumes-from www --link php-fpm:fpmservice -d sndnvaps/nginx
# see https://github.com/docker-library/docs/tree/master/nginx

Stop Containers

You must stop the contaners in the following sequence:

1. Nginx Container

2. PHP-FPM Container

3. WWW Container

4. MySQL Container

   get the runing container commit id

   $ docker ps

    root@sn-WorkStation:/opt/docker-lnmp# docker ps
CONTAINER ID        IMAGE                     COMMAND                CREATED              STATUS              PORTS                                      NAMES

# stop the container one by one 

# stop Nginx Container 
$ docker stop 93a5574fa67a

# stop PHP-FPM Container 
$ docker stop 4d6690e1bc39

# stop WWW Container

Have fun!
