# Wallabag

Wallabag is a self-hosted webapp which allows you to save URLs to "read later", similar to [Instapaper](https://www.instapaper.com/u) or [Pocket](https://getpocket.com/a/). Like Instapaper (_but **not** Pocket, sadly_), Wallabag allows you to **annotate** any pages you grab for your own reference.

All saved data (_pages, annotations, images, tags, etc_) are stored on your own server, and can be shared/exported in a variety of formats, including ePub and PDF.

There are plugins for [Chrome](https://chrome.google.com/webstore/detail/wallabagger/gbmgphmejlcoihgedabhgjdkcahacjlj) and [Firefox](https://addons.mozilla.org/firefox/addon/wallabagger/), as well as apps for [iOS](https://appsto.re/fr/YeqYfb.i), [Android](https://play.google.com/store/apps/details?id=fr.gaulupeau.apps.InThePoche), etc. Wallabag will also integrate nicely with my favorite RSS reader,  [Miniflux](https://miniflux.net/) (_for which there is an [existing recipe](/recipes/miniflux)_).

[Here's a video](https://player.vimeo.com/video/167435064) which shows off the UI a bit more.

## Ingredients

1. [Docker swarm cluster](/ha-docker-swarm/design/) with [persistent shared storage](/ha-docker-swarm/shared-storage-ceph.md)
2. [Traefik](/ha-docker-swarm/traefik) configured per design
3. DNS entry for the hostname you intend to use, pointed to your [keepalived](ha-docker-swarm/keepalived/) IP

## Preparation

### Setup data locations

We need a filesystem location to store images that Wallabag downloads from the original sources, to re-display when you read your articles, as well as nightly database dumps (_which you **should [backup](/recipes/duplicity/)**_), so create something like this:

```
mkdir -p /var/data/wallabag
cd /var/data/wallabag
mkdir -p {images,db-dump}
```

### Prepare environment

Create wallabag.env, and populate with the following variables. The only variable you **have** to change is SYMFONY__ENV__DOMAIN_NAME - this **must** be the URL that your Wallabag instance will be available at (_else you'll have no CSS_)
```
# For the DB container
POSTGRES_PASSWORD=wallabag
POSTGRES_USER=wallabag

# For the wallabag container
SYMFONY__ENV__DATABASE_DRIVER=pdo_pgsql
SYMFONY__ENV__DATABASE_HOST=db
SYMFONY__ENV__DATABASE_PORT=5432
SYMFONY__ENV__DATABASE_NAME=wallabag
SYMFONY__ENV__DATABASE_USER=wallabag
SYMFONY__ENV__DATABASE_PASSWORD=wallabag
SYMFONY__ENV__DOMAIN_NAME=https://wallabag.example.com
SYMFONY__ENV__DATABASE_DRIVER_CLASS=Wallabag\CoreBundle\Doctrine\DBAL\Driver\CustomPostgreSQLDriver
SYMFONY__ENV__MAILER_HOST=127.0.0.1
SYMFONY__ENV__MAILER_USER=~
SYMFONY__ENV__MAILER_PASSWORD=~
SYMFONY__ENV__FROM_EMAIL=wallabag@example.com
SYMFONY__ENV__FOSUSER_REGISTRATION=false


# If you decide to protect wallabag with an oauth_proxy, complete these
OAUTH2_PROXY_CLIENT_ID=
OAUTH2_PROXY_CLIENT_SECRET=
OAUTH2_PROXY_COOKIE_SECRET=
```

Now create wallabag-backup.env in the same folder, with the following contents. (_This is necessary to prevent environment variables required for backup from breaking the DB container_)

```
# For database backups
PGUSER=wallabag
PGPASSWORD=wallabag
PGHOST=db
BACKUP_NUM_KEEP=7
BACKUP_FREQUENCY=1d
```


### Setup Docker Swarm

Create a docker swarm config file in docker-compose syntax (v3), something like this:

!!! tip
        I share (_with my [patreon patrons](https://www.patreon.com/funkypenguin)_) a private "_premix_" git repository, which includes necessary docker-compose and env files for all published recipes. This means that patrons can launch any recipe with just a ```git pull``` and a ```docker stack deploy``` 👍

!!! note
    Setup unique static subnets for every stack you deploy. This avoids IP/gateway conflicts which can otherwise occur when you're creating/removing stacks a lot. See [my list](/reference/networks/) here.



## Serving

### Launch Wallabag stack

Launch the Wallabag stack by running ```docker stack deploy wallabag -c <path -to-docker-compose.yml>```

Log into your new instance at https://**YOUR-FQDN**, with user "wallabag" and default password "wallabag".

### Enable asynchronous imports

You'll have noticed redis, plus the pocket/instapaper-importing containers included in the .yml above. Redis is there to allow [asynchronous](https://github.com/wallabag/doc/blob/master/en/admin/asynchronous.md) imports, and pocket and instapaper are there since they're likely the most popular platform you'd _want_ to import from. Other possibilities (_you'll need to adjust the .yml_) are **readability**, **firefox**, **chrome**, and **wallabag_v1** and **wallabag_v2**.

Even with all these elements in place, you still need to enable Redis under Internal Settings -> Import, via the **admin** user in the webUI. Here's a screenshot to help you find it:

## Chef's Notes 📓

1. If you wanted to expose the Wallabag UI directly (_required for the iOS/Android apps_), you could remove the oauth2_proxy from the design, and move the traefik-related labels directly to the wallabag container. You'd also need to add the traefik_public network to the wallabag container. I found the iOS app to be unreliable and clunky, so elected to leave my oauth_proxy enabled, and to simply use the webUI on my mobile devices instead. YMMMV.
2. I've not tested the email integration, but you'd need an SMTP server listening on port 25 (_since we can't change the port_) to use it
