## WHAT IS DOCKER-DOTCLEAR

This repository contains all features to build or run Dotclear on a Docker environment.
It is hightly based on work from [darknao](https://github.com/darknao/docker-dotclear).

* Dotclear docker images are avaialable at [Docker hub](https://hub.docker.com/r/jcpd/docker-dotclear)
* Dotclear docker sources are avaialable at [Github repository](https://github.com/JcDenis/docker-dotclear)

### TAGS

Docker image tag is based on __Alpine Linux OS, Nginx server and PHP-FPM language__
It is composed of Dotclear version or release type.

* x.x : A given Dotclear version (ex: 2.31.1)
* latest : The latest stable Dotclear release
* dev : A Dotclear unstable (nightly) release

To build image from stable canal, from the Dokerfile path, execute :

    docker build -t dotclear:latest --build-arg CANAL=stable .

Or to build image from unstable canal, from the Dokerfile path, execute :

    docker build -t dotclear:dev --build-arg CANAL=unstable .

Builds should support postgresql and mysql database.

### DOCKER

Exemple of a docker compose file with a mariadb database.

    services:
      # MYSQL database service
      dc_db:
        image: mariadb:latest
        container_name: dotcleardb
        restart: unless-stopped
        command: --transaction-isolation=READ-COMMITTED --log-bin=binlog --binlog-format=ROW
        volumes:
          - dc_db:/var/lib/mysql
        environment:
          MYSQL_ROOT_PASSWORD: dotclear_root
          MYSQL_DATABASE: dotclear_db
          MYSQL_USER: dotclear_user
          MYSQL_PASSWORD: dotclear_pwd
    
      # PHP-FPM Service
      dc_app:
        image: jcpd/docker-dotclear:latest
        container_name: dotclearphp
        restart: unless-stopped
        volumes:
          - dc_app:/var/www/dotclear
        ports:
          - 80:80
        depends_on:
          - dc_db # MYSQL database service
        environment:
          # These variables are only used for first install, see inc/config.php
          DC_DBDRIVER: mysqlimb4 # MYSQL full UTF-8
          DC_DBHOST: dc_db # MYSQL database service
          DC_DBNAME: dotclear_db # MYSQL_DATABASE
          DC_DBUSER: dotclear_user # MYSQL_USER 
          DC_DBPASSWORD: dotclear_pwd # MYSQL_PASSWORD 
          DC_DBPREFIX: dc_ # Database tables prefix
          DC_ADMINMAILFROM: contact@exemple.com # Dotclear mail from
    
    volumes:
      dc_app: # NGINX (dotclear) volume
      dc_db: # MYSQL (database) volume

 * You __MUST__ replace database USER and PASSWORD by something else.

Then execute 

    docker-compose up -d

Dotclear is now available on your server host at http://locahost/
On first run Dotclear does its installation process and ask you to create a first user.
On first run you should wait that container download and install required version of Dotclear,
this may takes a while...

### BLOG

__Standard configuration__

These images use Dotclear URL rewriting in PATH INFO mode.
By default URL and path should be corrected by a custom plugin automatically.
Blogs URLs looks like:
 * http://localhost/default/
 * http://localhost/blog2/
 * ...

Blogs administration is available at http://localhost/admin

When you create a new blog in standard configuration,
you must use the _blog_id_ with the trailing slash in blog URL setting like http://localhost/blog_id/

__Non standard configuration__

Setup nginx server configuration (see bellow):
 * adapt _/var/www/dotclear/servers/*.conf_ to your needs
 
Then to configure blog:
 * go to the administration interface at http://my_custom_domain/admin,
 * left side menu _Blog settings_
 * panel _Advanced parameters_
 * set _Blog URL_ to http://my_custom_domain/ (with trailing slash)
 * set _URL scan method_ to 'PATH_INFO'

Then fix public_path and public_url for the blog:
 * go to the administration interface at http://my_custom_domain/admin,
 * left side menu _about:config_
 * panel _system_
 * set _public_path_ to the real path on system to public directory of the blog
 * set _public_url_ to the URL of the public directory of the blog

### STRUCTURE

Default root path of this image structure is in __/var/www/dotclear__
 * _app_ : Dotclear software files
 * _blogs_ : Blogs public directories
 * _cache_ : Dotclear template cache
 * _plugins_ : Third party plugins directory
 * _servers_ : Nginx servers configurations
 * _var_ : Dotclear var directory

### UPGRADE

To upgrade Dotclear to next version, just pull latest image and restart the docker container (recommanded)
or use Dotclear buitin update system.

Reminder: a dedicated dashboard is available at http://localhost/admin/upgrade.php

### TODO

* Add support of Dotclear's DEBUG mode for Dotclear and logs.
* Add better cache management. From another container or from Dotclear container.
* Add mail support.
* Enhance server and php configuration. From x.conf files.
