Download docker-compose.yml to dir named sentry
Change SENTRY_SECRET_KEY to random 32 char string
Run docker-compose up -d
Run docker-compose exec sentry sentry upgrade to setup database and create admin user
(Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
Run docker-compose restart sentry

Notes

If your local network use public IP ranges instead of private ones, make sure to add respecive RETURN rules to iptables to prevent looping issue
Set clash as DHCP's only DNS server to allow domain-based filter (shunting) rules work
Use lsof -i udp:53 to check if clash's DNS module work fine, otherwise you may have to kill systemd-resolved and any other processes occupying the UDP 53 port
The given scripts will NOT hangle the traffic of gateway itself since it is not recommend to do so. If you want to redirect the egress traffic of the gateway, the following material may be useful
