Managing Allow and Deny Lists
Last updated
This page explains how to add entries to the Allow and Deny lists at runtime and the manual steps needed to remove one.
Removing
There is no removal API. Because Check queries Redis first, editing the file alone has no effect; do all of the following:
- Delete the Redis key:
redis-cli DEL allow:203.0.113.10 - Remove the entry from the list file
- Restart every instance to clear the memory caches
Multi-Instance Boundaries
| Case | Behavior |
|---|---|
Instance A calls Add |
Redis applies to every instance at once; only A's memory cache and list file have the entry |
| Several instances share one list file | Each Add overwrites the whole file from its own cache, erasing entries other instances added |
| Restart after Redis is flushed | Only entries written to the list file come back |
When consistency across instances matters, treat Redis as the source of truth and the list file as a single-instance backup.
For how the lists load, are queried, and behave across instances, see Allow and Deny Lists.
