TT-RSS MYSQL

A simple Tiny Tiny RSS image which only supports MySQL with integrated feed updates.

• Support MySQL server.
• Built in Feed updating.
• Built-in TT-RSS updating.

IMPORTANT NOTES

This Docker image has several assumptions/prerequisites which need to be fulfilled, ignoring them will bring failure.

1. This Docker Image is for MySQL ONLY.
2. This image is for domains or sub-domains with /tt-rss/ in the URL. e.g. http://reader.mydomain.tld
3. MySQL needs to be installed in a separate Docker container.
4. MySQL needs to be configured and setup BEFORE this image is deployed (explained below).
5. If a previous MySQL instance is used and and old TT-RSS instance was using PHP 7.x then a “Data Fix” will need to be applied to the database as this image used PHP 8.1 and generates JSON differently. Failure to “Data Fix” the database could result in duplicate posts appearing in TT-RSS (explained below)

MySQL Setup

This image requires a database and database user be set up PRIOR to bringing up the image.

A new database and user can be created using the mysql command.

e.g. If you’re running the MySQL container from the Docker Compose example below you will need to run the following commands to create the database and user.

docker exec -it <MYSQL_CONTAINER> /bin/bash

Once inside the container run the following command to access MySQL.

mysql -u root -p

You will be prompted for the MYSQL_ROOT_PASSWORD (see Docker Compose example) Once in mysql run the following SQL commands to set up the database and user (see Docker Compose example to match up the values).

CREATE DATABASE <TTRSS_DB_NAME>;
CREATE USER '<TTRSS_DB_USER>' IDENTIFIED BY '<TTRSS_DB_PASS>';
GRANT ALL ON <TTRSS_DB_NAME>.* TO '<TTRSS_DB_USER>';
FLUSH PRIVILEGES;
\q

Now the tt-rss-mysql image can be started.

PHP 7 -> PHP 8 “Data Fix”

NOTE: If this is a fresh install of Tiny Tiny RSS then ignore this section.

PHP 7 stores the unique GUID used by each article in the following format:

{"ver":2,"uid":"2","hash":"SHA1:2b10b494802dc70e9d9d7676cdef0cf0f9969b78"}

PHP 8 stores the unique GUID used by each article in the following format:

{"ver":2,"uid":2,"hash":"SHA1:2b10b494802dc70e9d9d7676cdef0cf0f9969b78"}

Notice that the “uid” value is quoted with PHP 7 but not PHP 8.

The fix

To fix a previous MySQL database populated by PHP 7 the following SQL commands need to be used via the mysql commandline tool.

USE <TTRSS-DATABASE>;

UPDATE ttrss_entries
SET guid = replace(replace(guid,'"uid":"', '"uid":'),'", "hash":', ',"hash":')
WHERE guid LIKE '%"uid":"%"%';
