 Paheko on Alpine Linux with Docker. With Alpine 3.1.16, PHP 8.1 and Nginx 1.22.0.
 
-## Usage
+Fork of https://github.com/HluthWigg/docker-paheko to adapt to latest paheko releases.
 
-Pre-requisite : *Docker Desktop*.
+Support paheko release 1.3.4 only.
 
-**Option 1** from [*Docker Hub*](https://hub.docker.com/r/hluthwigg/paheko) : download the image and launch the container in one line
-```
-sudo docker run -d -t --name ga -p 80:80 -v vol-ga:/var/www/paheko/data/ hluthwigg/paheko 
-```
-
-
-**Option 2** from the *Github* repository : build the image and launch the container
+## how to build
 
 ```
-# clone the repository
-git clone https://github.com/HluthWigg/docker-paheko.git
-cd docker-paheko
+docker build -t paheko .
 
-# build the image
-sudo docker build -t paheko .
+docker tag paheko forge.lefuturiste.fr/mbess/paheko:1.3.4
 
-# launch the container
-sudo docker run -d -t --name ga -p 80:80 -v vol-ga:/var/www/paheko/data/ paheko 
+docker push forge.lefuturiste.fr/mbess/paheko:1.3.4
 ```
-**Then open [http://localhost:80](http://localhost:80) in your browser.**
-
-<hr>
-
-To stop and remove the container
-```
-sudo docker rm -f ga
-```
-
-To shell inside the container :
-```
-sudo docker exec -it ga sh
-```
-
-To start off a new database, just remove the volume :
-```
-sudo docker volume rm vol-ga
-```
-and run again.

-## Acknowledgements
-
-This is inspired by [Aurélien Janvier](https://github.com/ajanvier/docker-garradin)'s and [Tim de Pater](https://github.com/TrafeX/docker-php-nginx)'s works. Thanks to them !
-
-It also relies on resources hosted on Garradin's fossil server :
-
-+ [general installation page](https://fossil.kd2.org/garradin/wiki?name=Installation) in French
-+ [Debian/Ubuntu setup page](https://fossil.kd2.org/garradin/wiki?name=Installation%20sous%20Debian-Ubuntu)
-+ [Nginx configuration](https://fossil.kd2.org/garradin/wiki?name=Installation/nginx)

-## More explanations
-
-*Disclaimer : those comments come from a newbie.*
-
-**Garradin/Paheko** is a PHP-written website, not a simple software.
-Therefore, its installation is not that easy.
-It requires a web server (Nginx or Apache), with a PHP interpreter (PHP-FPM).
-
-**Supervisord** is used to launch the two required services, Nginx and PHP-FPM, as you can see in *config/supervisord.conf*.
-Because the conf file has no "supervisorctl" section (I don't know how to write a working one), it is not possible to use `supervisorctl restart nginx` inside the container.
-This would be nice to test new parameters without restarting the whole container. 
-Instead I intensively used this command.
-```
-sudo docker rm -f ga ; sudo docker build -t garradin . ; sudo docker run -d -t --name ga -p 80:80 -v vol-ga:/var/www/garradin/data/ garradin 
-```
-You can still make sure that both Nginx and PHP-FPM services work with a simple `ps`.
-And you can check that your configuration is well taken into account by `nginx -T` (with a lowercase `-t`, it checks the configuration file) and by `php-fpm81 -tt`.
-
-**Nginx and PHP-FPM** communicate through a socket (*/run/garradin.socket*) as you can see in *config/nginx-garradin.conf* and *config/fpm-garradin.conf*.
-As I imagine it, when Nginx receive a request over a PHP file, it sends it to PHP for interpretation and PHP hands back a HTML file to Nginx which sends it to the browser.
-
-**Beware :** in the nginx configuration file *paheko.conf*, the root has to be the ***www***, **inside** the *garradin* folder, not the *garradin* itself.
-Otherwise, you would receive a warning "Garradin n'est pas installé sur un sous-domaine dédié."
-
-### Version compatibility
-
-If you want to test another Paheko version, you first need to check [available versions of Paheko](https://fossil.kd2.org/garradin/uvlist).
-Then you can put it as `PAHEKO_VERSION` in the *Dockerfile*.
-If the version you want is only provided with the format *.tar.bz2*, change `tar xzvf garradin-$GARRADIN_VERSION.tar.gz` by `tar xjvf paheko-$PAHEKO_VERSION.tar.bz2`.
-
-Then you have to check which PHP version is required for this Garradin version. You can do that with a case-sensitive "PHP" search on the [changelog](https://fossil.kd2.org/garradin/wiki/?name=Changelog).
-
-Depending on this, you may want a newer or an older Alpine version, so that the PHP version you're looking for is available. Just change `ALPINE_VERSION` in the *Dockerfile*.
-
-**Modules** Make sure you have installed all necessary modules.
-For instance, I experienced a crash because the PHP function `finfo_open()`, provided by the module *php81-fileinfo*, was not found.
-Indeed the module was not installed.
-I added it to the `RUN apk add` line in the **Dockerfile**
-
-### Plugins
-
-(Thanks @gromain) All available plugins as of July 3rd, 2022 in the docker image.
-You can install more plugins as explained [here](https://fossil.kd2.org/garradin-plugins/index).
-You need to download the `.tar.gz` in the directory `/var/www/garradin/data/plugins` and then connect to garradin (*localhost:80*) > *Configuration* > *Plugins* and then tick and install desired plugins.
-**DomPDF** requires **php-zip**.
