Currently WebServer consists of such images:

• Data-only container (based on official busybox image)
• logrotate container (based on official debian:jessie image)
• MariaDB (based on official MariaDB image)
• Nginx (based on official Nginx image)
• PHP-FPM (based on nazarpc/php:fpm image, which is official image + bunch of frequently used PHP extensions)
• SSH (based on phusion/baseimage image, contains pre-installed curl, git, mc, wget, php-cli and composer for your convenience)
• PhpMyAdmin (based on nazarpc/phpmyadmin image, which is official php image with Apache2, where PhpMyAdmin was installed)
• Consul (based on official debian:jessie image)
• HAProxy (based on official haproxy image)
• backup container (based on official busybox image)
• restore container (based on official busybox image)
• nazarpc/webserver-apps for ready to use applications that plays nicely with images mentioned above

How to use

The most convenient way to use all this is Docker Compose

At first you'll need to create persistent data-only container that will store all files, databases, ssh keys and settings of all these things:

docker run --name example.com nazarpc/webserver:data

This container will start and stop immediately, that is OK.

After this create directory for your website, it will contain docker-compose.yml file and potentially more files you'll need:

mkdir example.com
cd example.com

Now create docker-compose.yml inside with following contents:

data:
  image: nazarpc/webserver:data
  volumes_from:
    - example.com

logrotate:
  image: nazarpc/webserver:logrotate
  restart: always
  volumes_from:
    - data

mariadb:
  image: nazarpc/webserver:mariadb
  restart: always
  volumes_from:
    - data

nginx:
  image: nazarpc/webserver:nginx
  links:
    - php
#  ports:
#    - {ip where to bind}:{port on localhost where to bind}:80
  restart: always
  volumes_from:
    - data

php:
  image: nazarpc/webserver:php-fpm
  links:
    - mariadb:mysql
  restart: always
  volumes_from:
    - data

#phpmyadmin:
#  image: nazarpc/webserver:phpmyadmin
#  links:
#    - mariadb:mysql
#  restart: always
#  ports:
#    - {ip where to bind}:{port on localhost where to bind}:80

ssh:
  image: nazarpc/webserver:ssh
  restart: always
  volumes_from:
    - data
#  ports:
#    - {ip where to bind}:{port on localhost where to bind}:22

Now customize it as you like, feel free to comment-out or remove mariadb, php or ssh container if you have just bunch of static files, also you can uncomment phpmyadmin container if needed.

When you're done with editing:

That is it, you have whole WebServer up and running!

Also you might be interested in advanced examples with load balancing, scaling and using Docker Networking feature.

Upgrade

You can easily upgrade your WebServer to new version of software.

Using Docker Compose upgrade is very simple:

docker-compose pull
docker-compose up -d

All containers will be recreated from new images in few seconds.

Backup/restore images are not present in docker-compose.yml, so if you're using them - pull them manually.

Alternatively you can pull all images manually:

docker pull nazarpc/webserver:data
docker pull nazarpc/webserver:logrotate
docker pull nazarpc/webserver:mariadb
docker pull nazarpc/webserver:nginx
docker pull nazarpc/webserver:php-fpm
docker pull nazarpc/webserver:ssh
docker pull nazarpc/webserver:backup
docker pull nazarpc/webserver:restore

And again in directory with docker-compose.yml:

Backup

To make backup you need to only backup volumes of data-only container. The easiest way to do that is using nazarpc/webserver:backup image:

docker run --rm --volumes-from example.com -v /backup-on-host:/backup --env BACKUP_FILENAME=new-backup nazarpc/webserver:backup

This will result in /backup-on-host/new-backup.tar file being created - feel free to specify other directory and other name for backup file.

All other containers are standard and doesn't contain anything important, that is why upgrade process is so simple.

NOTE: You'll likely want to stop MariaDB instance before backup (it is enough to stop first node in case of MariaDB cluster with 2+ nodes)

Restore

Restoration from backup is not more difficult that making backup, there is nazarpc/webserver:restore image for that:

docker run --rm --volumes-from example.com -v /backup-on-host/new-backup.tar:/backup.tar nazarpc/webserver:restore

That is it, empty just created example.com container will be filled with data from backup and ready to use.

SSH

SSH might be needed to access files from outside, especially with git.

Before you enter ssh container via SSH for the first time, you need to create file /data/.ssh/authorized_keys and put your public key contents inside (how to generate SSH keys). For example, you can do that from Midnight Commander file manager

docker-compose run ssh mc

Now you should be able to access container as git user:

Internal structure

Internally all that matters is /data directory - it contains all necessary symlinks for your convenience - here you can see files for Nginx and MariaDB, their logs and configs, PHP-FPM's config, SSH config and SSH keys directory. That is all what will be persistent, everything else outside /data will be lost during upgrade.

Update configuration

If you update some configuration - you don't need to restart everything, restart only things you need, for instance:

docker-compose restart nginx
