# Dockerized tt-rss using docker-compose
|
|
|
|
The idea is to provide tt-rss working (and updating) out of the box with minimal fuss.
|
|
|
|
**This setup uses official prebuilt images from Docker Hub. Note that images are only available for Linux/amd64.**
|
|
|
|
- [FAQ](https://git.tt-rss.org/fox/ttrss-docker-compose/wiki#faq)
|
|
|
|
General outline of the configuration is as follows:
|
|
|
|
- separate containers (frontend: nginx, database: pgsql, app and updater: php/fpm)
|
|
- tt-rss latest git master (and nginx_xaccel plugin) baked into container on build
|
|
- local plugins are updated on container restart
|
|
- images are pulled from [Docker Hub](https://hub.docker.com/u/cthulhoo) (automatically built and published on tt-rss master source update)
|
|
- working copy is stored on (and rsynced over on restart) a persistent volume so plugins, etc. could be easily added
|
|
- database schema is updated automatically
|
|
- nginx has its http port exposed to the outside
|
|
- feed updates are handled via update daemon started in a separate container (`updater`)
|
|
- optional `backups` container which performs tt-rss database backup once a week
|
|
|
|
### Installation
|
|
|
|
#### Get [docker-compose.yml](https://git.tt-rss.org/fox/ttrss-docker-compose/src/static-dockerhub/docker-compose.yml) and [.env-dist](https://git.tt-rss.org/fox/ttrss-docker-compose/src/static-dockerhub/.env-dist)
|
|
|
|
```sh
|
|
git clone https://git.tt-rss.org/fox/ttrss-docker-compose.git ttrss-docker
|
|
cd ttrss-docker
|
|
git checkout static-dockerhub
|
|
```
|
|
|
|
You're interested in ``docker-compose.yml`` stored in root directory, as opposed to ``src``.
|
|
|
|
Latter directory is used to build images for publishing on Docker Hub. Use it if you
|
|
want to build your own containers.
|
|
|
|
#### Edit configuration files
|
|
|
|
Configuration is done primarily through the [environment](https://git.tt-rss.org/fox/ttrss-docker-compose/wiki#how-do-i-set-global-configuration-options). Copy ``.env-dist`` to ``.env`` and edit any relevant variables you need changed.
|
|
|
|
You will likely have to change ``TTRSS_SELF_URL_PATH`` which should equal fully qualified tt-rss
|
|
URL as seen when opening it in your web browser. If this field is set incorrectly, you will
|
|
likely see the correct value in the tt-rss fatal error message.
|
|
|
|
Legacy configuration file (`config.php`) is not created automatically, if you need it, copy it from `config.php-dist` manually.
|
|
|
|
By default, frontend container binds to `localhost` port `8280`. If you want the container to be
|
|
accessible on the net, without using a reverse proxy sharing same host, you will need to
|
|
remove ``127.0.0.1:`` from ``HTTP_PORT`` variable in ``.env``.
|
|
|
|
Please don't rename the services inside `docker-compose.yml` unless you know what you're doing. Web container expects application container to be named `app`, if you rename it and it's not accessible via Docker DNS as `http://app` you will run into 502 errors on startup.
|
|
|
|
#### Pull and start the container
|
|
|
|
```sh
|
|
docker-compose pull && docker-compose up -d
|
|
```
|
|
|
|
See ``docker-compose`` documentation for more information and available options.
|
|
|
|
#### Default login credentials
|
|
|
|
Username: `admin`, password: `password`
|
|
|
|
### Updating
|
|
|
|
You will need to pull a fresh image from Docker Hub to update tt-rss source code. Working copy
|
|
will be synchronized on startup.
|
|
|
|
[Ouroboros](https://hub.docker.com/r/pyouroboros/ouroboros) or [Watchtower](https://hub.docker.com/r/containrrr/watchtower) easily automates this process.
|
|
|
|
If database needs to be updated, tt-rss will prompt you to do so on next page refresh. Normally this happens
|
|
automatically on container startup.
|
|
|
|
#### Updating container scripts
|
|
|
|
Latest tt-rss source code expects latest container scripts and vice versa. Updating both is a good idea. Docker Hub image is less dependent on container scripts because most of startup logic is baked into the image so you don't need to worry too much about it.
|
|
|
|
1. Stop the containers: ``docker-compose down && docker-compose rm``
|
|
2. Update scripts from git: ``git pull origin static-dockerhub`` and apply any necessary modifications to ``.env``, etc.
|
|
3. Pull fresh images and start the containers: ``docker-compose pull && docker-compose up``
|
|
