 # feed2toot-docker
 
+A Docker image for [feed2toot](https://gitlab.com/chaica/feed2toot).
+
+## Usage
+
+Create a `feed2toot` directory and your custom `feed2toot.ini` with the [feed2toot config](https://gitlab.com/chaica/feed2toot#use-feed2toot) in this directory. You can use the path `/feed2toot` in that file, as the directory will be mounted to that path. 
+
+Example:
+
+```ini
+[mastodon]
+instance_url=<mastodon-url>
+; Here you need the two files created by register_feed2toot_app
+user_credentials=/feed2toot/feed2toot_usercred.txt
+client_credentials=/feed2toot/feed2toot_clientcred.txt
+; Default visibility is public, but you can override it:
+; toot_visibility=unlisted
+
+[cache]
+cachefile=/feed2toot/feed2toot.db
+cache_limit=10000
+
+[lock]
+lock_file=/feed2toot/feed2toot.lock
+lock_timeout=300
+
+[rss]
+uri=<rss-url>
+; uri_list=/feed2toot/rsslist.txt
+toot={title} {summary:400}
+
+[hashtaglist]
+; several_words_hashtags_list=/feed2toot/hashtags.txt
+
+[feedparser]
+accept_bozo_exceptions=true
+
+[media]
+; custom=/feed2toot/media/logo.png
+```
+
+To [create the authorization for feed2toot](https://gitlab.com/chaica/feed2toot#create-the-authorization-for-the-feed2toot-app) you can also use this image:
+
+```bash
+docker run --rm -it -v /your/path/feed2toot:/feed2toot samuelph/feed2toot register_feed2toot_app
+```
+
+Finally copy the [`cron`](cron) file in the `feed2toot` directory and run the docker image:
+
+```bash
+docker run -d -v /your/path/feed2toot:/feed2toot samuelph/feed2toot
+```
+
+Optionally you can adjust the cron job to fit your needs by editing the `cron` file. Per default the cron job runs every minute.
+
+To run the image with Docker Compose you can just use this:
+
+```yaml
+services:
+  feed2toot:
+    image: samuelph/feed2toot
+    restart: always
+    volumes:
+      - /your/path/feed2toot:/feed2toot
+```
+
+## Usage with multiple feeds
+
+You can also use a single container to handle multiple feeds. Therefore you should create a folder for each feed in the `feed2toot` folder from above. Don't forget to update the paths in the `*.ini` files. Finally you can add a cronjob for each feed in the `cron` file:
+
+```
+*/3 * * * * /usr/local/bin/feed2toot -c /feed2toot/feed1/feed2toot.ini > /proc/1/fd/1 2>/proc/1/fd/2
+*/7 * * * * /usr/local/bin/feed2toot -c /feed2toot/feed2/feed2toot.ini > /proc/1/fd/1 2>/proc/1/fd/2
+```
+
+Now you can run the image like before.
