I’ve installed tiny tiny rss as a replacement for Feedly once they started inserting ads that looked like articles. Deceptive advertising. I’m not a fan.
I’ve spun up linuxserver’s version of it in docker and it works pretty well except for updating articles. I couldn’t find a great guide on configuring it for updates specifically within a docker container, so here is mine. My solution was to have a cron job running on the docker host to run the feed update script within the docker container, inspired by this post.
The trick is to use the docker exec command to run a command from the docker host but execute it within the running container.
docker exec -u 1001 -it TinyTinyRSS /usr/bin/php /config/www/tt-rss/update.php --feeds --quiet
The -u command specifies which user ID to run the command as. TinyTinyRSS is the name of my container. I’ve set this to run every 15 minutes with the following crontab syntax:
*/15 * * * * /usr/bin/docker exec -u 1001 -d TinyTinyRSS /usr/bin/php /config/www/tt-rss/update.php --feeds --quiet
edit: Modified the crontab entry to make it work properly per this post.
