selfoss is a new multipurpose rss reader, live stream, mashup, aggregation web application.

This Dockerfile provides a selfoss image.

Setup

All data is stored in /var/www/html/data, which is persisted as a volume, but it might be reasonable to export it to the local file system. Port 80 is exposed for the web application.

Data Folders

Selfoss requires a bunch of folders in the data directory. Make sure to create them if you export the volume, running following from the data volume's root:

mkdir cache favicons logs thumbnails sqlite
chown -R 33 . # UID 33 is www-data inside the container

Configuration

Usually, the configuration file would be stored in /var/www/html/config.ini, and thus not persisted. The image symlinks it into the data directory, so you can edit /var/www/html/data/config.ini instead. For configuration directives, follow the selfoss documentation. Generally, no documentation is required; but strongly recommended (ie., to make it password protected).

Database

Per default, selfoss relies on SQLite, which should be fully sufficient for a single-user application like selfoss. If you prefer a "real" database management application, the image might be missing PHP modules (patches to the Dockerfile are welcome).

Update Cronjob

Add a cronjob somewhere to fetch updates feeds on a regular base. Following line would update the feeds all 15 minutes:

*/15 * * * * curl -s http://example.org/update >/dev/null

If you set up a password-protected login, you will be required to allow anonymous updates, adding

allow_public_update_access=1

to your config.ini.

Nginx Proxy

In case you want to proxy selfoss with Nginx, this is a proposal for the server { } directive:

location ~* ^/(data\/logs|data\/sqlite|config\.ini|\.ht|password) {
    deny all; # Disable temporarilly to generate a password usingi the `/password` page
}

location /update {
    proxy_set_header Host $http_host;
    proxy_read_timeout 300;
    proxy_pass http://selfoss:80;
}

location / {
    proxy_set_header Host $http_host;
    proxy_pass http://selfoss:80;
}

Running a Container

The most basic run command would be:

docker run -d \
    --name 'selfoss' \
    --publish 80:80 \
    --volume /srv/selfoss:/var/www/html/data \
    jenserat/selfoss

Upgrading and Maintenance

Selfoss will automatically upgrade the database. For other maintenance tasks during upgrades, refer to the selfoss documentation.

To enter the container and perform maintenance, use (given you named the container selfoss):

docker exec -ti selfoss /bin/bash
