Nginx settings that permits to proxy a wallabag docker

docker-wallabag-proxy

AppKernel.php file that permits to Wallabag to ignore 'domain_name' / 'SYMFONY__ENV__DOMAIN_NAME' parameter (https://your-wallabag-url-instance.com) and provide service from any domain or behind any proxy.

How it works

Compared to original wallabag/wallabag (https://github.com/wallabag/wallabag) and wallabag/docker (https://registry.hub.docker.com/r/wallabag/wallabag) the only change is a comment into AppKernel.php (app/AppKernel.php of wallabag, /var/www/wallabag/app/AppKernel.php of wallabag docker)

...
        $loader->load(function ($container) {
            if ($container->getParameter('use_webpack_dev_server')) {
                $container->loadFromExtension('framework', [
                   'assets' => [
                       'base_url' => 'http://localhost:8080/',
                   ],
               ]);
            } else {
                $container->loadFromExtension('framework', [
                    'assets' => [
-                        'base_url' => $container->getParameter('domain_name'),
+                        // 'base_url' => $container->getParameter('domain_name'),
                    ],
                ]);
            }
        });
...

The standard wallabag redirect to (defaul) https://your-wallabag-url-instance.com (or custom domain_name / SYMFONY__ENV__DOMAIN_NAME parameter) after connetion to the service. Also all URLs of images and CSS contains the same domain.

With this comment Symfony behind wallabag doesn't use a specific base_url but 'relative' to the domain that expose the service.

Even if the service is behind one or more proxies there will be no problems.

Easy guide for Synology NAS docker

Into File Manager create the folder structure docker/wallabag/var/www/wallabag/app

Create/upload the file AppKernel.php of this GitHub repository.

Install the docker app, downoload wallabag/wallabag from Registry and double click on it in Image.

On Volume tab click Add File and select from File Manager docker/wallabag/var/www/wallabag/app/AppKernel.php and write /var/www/wallabag/app/AppKernel.php into Mount path.

The docker will see, and use, the modified file.

_{PS: the mount of folder docker/wallabag/var/www/wallabag/data to mount data /var/www/wallabag/data permits the easy upgrade of docker new image versions mantaining databases and users password.}

On Port Settings tab click Add and specify a Local Port for Container Port 80.

You can now provide a wallabag service for any domain.
