[Tt-rss](https://tt-rss.org) is an open source web-based news feed (RSS/Atom) reader and aggregator, designed to allow you to read news from any location, while feeling as close to a real desktop application as possible.
Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
This image provides various versions that are available via tags. `latest` tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.
| Tag | Description |
| :----: | --- |
| latest | Stable Tiny Tiny RSS releases |
| develop | Develop Tiny Tiny RSS releases from HEAD of their master branch |
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.
You must create a user and database for tt-rss to use in a mysql/mariadb or postgresql server. PostgreSQL is recommended, as InnoDB is required if using MySQL. A basic nginx configuration file can be found in /config/nginx/site-confs , edit the file to enable ssl (port 443 by default), set servername etc.. Self-signed keys are generated the first time you run the container and can be found in /config/keys , if needed, you can replace them with your own.
The container can configure itself using environment variables, the gaurd for this logic to run is if the variable `DB_TYPE` is set. The most common variables to set are a URL for the application and a database endpoint. IE:
Please note if you use this method you need to have an already initialized database endpoint. We do our best to ensure that anything in the config.php can be set via these environment variables.
