Prerequisites: you are running gitlab in a docker container.
First step, attach shell to docker container:
sudo docker exec -it gitlab /bin/bash
Next step, start redis:
/opt/gitlab/embedded/bin/redis-cli -s /var/opt/gitlab/redis/redis.socket
Check for rack keys:
/var/opt/gitlab/redis/redis.socket> KEYS *rack*The result should be similar to:
1) "cache:gitlab:rack::attack:allow2ban:ban:172.17.0.1"
Finally, delete the rack key:
DEL "cache:gitlab:rack::attack:allow2ban:ban:172.17.0.1"
