# Tiny Tiny RSS on dokku

Runs as a [Dockerfile deployment](http://dokku.viewdocs.io/dokku/deployment/methods/dockerfiles/) with a [Postgres database](https://github.com/dokku/dokku-postgres). Pulls [TTRSS release](https://git.tt-rss.org/git/tt-rss) into an [nginx base image](https://hub.docker.com/_/nginx/) with PHP7, parses `DATABASE_URL` environment variable and starts the fetch daemon using supervisord.

## Setup

```bash
dokku plugin:install https://github.com/dokku/dokku-postgres.git

dokku apps:create ttrss
dokku ps:scale ttrss web=0
dokku postgres:create ttrssdb_11_2
dokku postgres:link ttrssdb_11_2 ttrss
dokku config:set ttrss SELF_URL_PATH=http://ttrss.example.com/

git remote add dokku dokku@example.com:ttrrs
git push dokku

dokku run ttrss php7 /var/lib/tt-rss-install/install-db.php
dokku ps:scale ttrss web=1
```

### Setup

```bash
dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git

dokku config:set --no-restart ttrss DOKKU_LETSENCRYPT_EMAIL=todo@example.com

## Upgrade

### TTRSS

* Upgrade base image in `Dockerfile`: https://hub.docker.com/_/nginx?tab=tags
* Upgrade TTRSS release in `Dockerfile`
* Propagate updates in `config.php-dist` to `config.php`: https://git.tt-rss.org/fox/tt-rss/src/19.8/config.php-dist

```bash
dokku postgres:export ttrssdb_11_4 > ttrss.db
git push dokku
# go to Tiny Tiny RSS, it will ask to upgrade database, do it and check app is working
rm ttrss.db
```

### Database

```bash
# upgrade from Postgres 10.2 to 11.4
dokku plugins:upgrade postgres
dokku postgres:create ttrssdb_11_4
dokku postgres:export ttrssdb_10_2 > ttrss.db
dokku postgres:import ttrssdb_11_4 < ttrss.db
dokku postgres:link ttrssdb_11_4 ttrss
dokku postgres:promote ttrssdb_11_4 ttrss

# check app is working, then delete old database
dokku postgres:unlink ttrssdb_10_2 ttrss
dokku postgres:destroy ttrssdb_10_2
