## 3. 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) or [Github registry](https://github.com/JcDenis/docker-dotclear/pkgs/container/docker-dotclear)
* Dotclear docker sources are avaialable at [Github repository](https://github.com/JcDenis/docker-dotclear)


### 3.1 TAGS

Docker images are based on __Alpine Linux OS, Nginx server and PHP-FPM language__. 
Image tags are composed of Dotclear version or release type:

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


### 3.2 BUILDS

Clone this repository:

    git clone https://github.com/JcDenis/docker-dotclear.git

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 testing canal, from the Dokerfile path, execute:

    docker build -t dotclear:testing --build-arg CANAL=testing .

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 and sqlite database
* linux/386,linux/amd64,linux/arm64,linux/arm/V7 plateforms
* docker container healthcheck


### 3.3 DOCKER


#### 3.3.1 Exemple of a docker compose file with a mariadb database

Create and edit a **docker-compose.yaml** file and put into it this contents :

    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
        healthcheck:
          test: ["CMD", "healthcheck.sh", "--connect", "--innodb_initialized"]
          start_period: 10s
          interval: 10s
          timeout: 5s
          retries: 3
    
      # 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
            condition: service_healthy # Waiting for database ready
        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...


#### 3.3.2 Exemple of a docker compose file with an SQLite database and a single container

Create and edit a **docker-compose.yaml** file and put into it this contents :

    services:
      dotclear:
        image: jcpd/docker-dotclear:latest
        container_name: dotclear
        restart: unless-stopped
        volumes:
          - ./dotclear:/var/www/dotclear
        ports:
          - 80:80
        environment:
          DC_DBDRIVER: sqlite
          DC_DBNAME: \var\www\dotclear\sqlite.db
          DC_ADMINMAILFROM: contact@exemple.com

Then execute:

    docker-compose up -d


#### 3.3.3 Direct docker run without docker compose

Exemple with a simple docker command :

    docker run -d --name dotclear -p 80:80 -v dotclear:/var/www/dotclear -e DC_DBDRIVER=sqlite -e DC_DBNAME=/var/www/dotclear/sqlite.db -e DC_ADMINMAILFROM=contact@exemple.com jcpd/docker-dotclear:latest

SQLite database will be stored in folder \var\www\dotclear


### 3.4 BLOG


#### 3.4.1 Standard configuration by subfolders

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 this configuration,
you must use the _blog_id_ with the trailing slash in blog URL setting like http://localhost/blog_id/

__Web server configuration__

To customized web server configuration for subfolders, edit:

> /var/www/dotclear/app/servers/subfolder.conf

Original contents looks like:

    server {
        server_name localhost;
        include /etc/nginx/snippets/snippets_subfolder.conf;
        include /etc/nginx/snippets/snippets_common.conf;
    }


#### 3.4.2 Standard configuration by subdomains

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://default.domain.tld/
 * http://blog2.domain.tld/
 * ...

Blogs administration is available at http://xxx.domain.tld/admin

When you create a new blog in this configuration,
you must use the _blog_id_ as subdomain in blog URL setting like http://blog_id.domain.tld/

__Web server configuration__

To customized web server configuration for subdomains, edit:

> /var/www/dotclear/app/servers/subdomain.conf

Original contents looks like:

    server {
        server_name ~^(?<dc_blog_id>\w*?)?\.?(\w+\.\w+)$;
        if ($dc_blog_id = '') {
                set $dc_blog_id default;
        }
        if ($dc_blog_id = 'blog') {
                set $dc_blog_id default;
        }
        include /etc/nginx/snippets/snippets_subdomain.conf;
        include /etc/nginx/snippets/snippets_common.conf;
    }


#### 3.4.3 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


### 3.5 STRUCTURE

Default root path of this image structure is in __/var/www/dotclear__ with sub folders:

 * _app_ : Dotclear application files
 * _blogs_ : Blogs public directories
 * _cache_ : Dotclear template cache
 * _plugins_ : Third party plugins directory
 * _servers_ : Nginx servers configurations
 * _themes_ : Dotclear themes directory
 * _var_ : Dotclear var directory


### 3.6 UPGRADE

To upgrade Dotclear to next version it is recommanded to pull latest image and restart the docker container:

    docker pull jcpd/docker-dotclear:latest && docker compose up -d

or use Dotclear buitin update system but themes wiil not be updated.
