Docker and SQLite

The performance of the handful of tags to the SQLite DB is not great and I get a lot of log errors with file locked etc.

This is no surprise. SQLite just isn't made for the Tag History use-case. Recent discussion on SQLite:

SQLite DB failed to load after polling rate

This. Use a real database. A SQLite DB, fundamentally, is a generic configuration file manipulated with SQL. Its codebase is optimized for compact single file storage and a minimalist library footprint. It is not and never will be suitable for Tag History in any ordinary sense. If you want maximum utility in a free database, I recommend PostgreSQL. I think MariaDB is also a good choice.
