# A primitive set of scripts to deploy tt-rss via docker-compose
|
|
|
|
The idea is to provide tt-rss working (and updating) out of the box with minimal fuss.
|
|
|
|
Not fully tested yet, don't use in production unless you know what you're doing. Some features may be unimplemented or broken, check the [TODO](https://git.tt-rss.org/fox/ttrss-docker-compose/wiki/TODO).
|
|
|
|
The general outline of the configuration is as follows:
|
|
|
|
- three linked containers (frontend: caddy, database: pgsql, application: php/fpm)
|
|
- caddy has its http port exposed to the outside
|
|
- feed updating is done via embedded cron job, every 15 minutes
|
|
- tt-rss source updates from git master repository on container restart
|
|
- schema is installed automatically if it is missing
|
|
- config.php is generated if it is missing
|
|
- SSL termination not included, use a sidecar container for that (TODO)
|
|
- tt-rss code is stored on a persistent volume so plugins, etc. could be easily added
|
|
|
|
### Installation
|
|
|
|
#### Check out scripts from Git:
|
|
|
|
```
|
|
git clone https://git.tt-rss.org/fox/ttrss-docker-compose.git ttrss-docker && cd ttrss-docker
|
|
```
|
|
|
|
#### Edit configuration files:
|
|
|
|
Copy ``.env-dist`` to ``.env`` and edit any relevant variables you need changed.
|
|
|
|
* You will likely have to change ``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.
|
|
|
|
Note: ``SELF_URL_PATH`` is updated in generated tt-rss ``config.php`` automatically on container
|
|
restart. You don't need to modify ``config.php`` manually for this.
|
|
|
|
* By default, 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``.
|
|
|
|
#### Build and start the container
|
|
|
|
``docker-compose up --build``
|
|
|
|
See docker-compose documentation for more information and available options.
|
|
|
|
### Updating
|
|
|
|
Restarting the container will update tt-rss from the origin repository. If database needs to be updated,
|
|
tt-rss will prompt you to do so on next page refresh.
|
|
|
|
#### Updating container scripts
|
|
|
|
1. Stop the containers: ``docker-compose down && docker-compose rm``
|
|
2. Update scripts from git: ``git pull origin master`` and apply any necessary modifications to ``.env``, etc.
|
|
3. Rebuild and start the containers: ``docker-compose up --build``
|
|
|
|
|
|
### Using SSL with Letsencrypt (untested!)
|
|
|
|
- ``HTTP_HOST`` in ``.env`` should be set to a valid hostname (i.e. no localhost or IP address)
|
|
- comment out ``web`` container, uncomment ``web-ssl`` in ``docker-compose.yml``
|
|
- ports 80 and 443 should be externally accessible i.e. not blocked by firewall and/or conflicting with host services
|
|
|
|
### How do I add plugins and themes?
|
|
|
|
By default, tt-rss code is stored on a persistent docker volume (``app``). You can find
|
|
its location like this:
|
|
|
|
``docker volume inspect ttrss-docker_app | grep Mountpoint``
|
|
|
|
Alternatively, you can mount any host directory as ``/var/www/html`` by updating ``docker-compose.yml``, i.e.:
|
|
|
|
```
|
|
volumes:
|
|
- app:/var/www/html
|
|
```
|
|
|
|
Replace with:
|
|
|
|
```
|
|
volumes:
|
|
- /opt/tt-rss:/var/www/html
|
|
```
|
|
|
|
Copy and/or git clone any third party plugins into ``plugins.local`` as usual.
|
|
|
|
### How do I put this container behind a reverse proxy?
|
|
|
|
A common pattern is shared nginx doing SSL termination, etc.
|
|
|
|
```
|
|
location /tt-rss/ {
|
|
proxy_set_header Host $host;
|
|
proxy_set_header X-Real-IP $remote_addr;
|
|
proxy_set_header X-Forwarded-For $remote_addr;
|
|
proxy_set_header X-Forwarded-Proto $scheme;
|
|
|
|
proxy_pass http://127.0.0.1:8280/tt-rss/;
|
|
break;
|
|
}
|
|
```
|
|
|
|
You will need to set ``SELF_URL_PATH`` to a correct (i.e. visible from the outside) value in the ``.env`` file.
