Though this is unlikely to be required in small deployment, you can fine-tune some other settings like number of workers using environment variables that are processed by [Rocket](https://rocket.rs), please see details in [documentation](https://rocket.rs/guide/configuration/#environment-variables).

### Fail2Ban Setup
Bitwarden_rs logs failed login attempts to stdout. We need to set this so the host OS can see these. Then we can setup Fail2Ban.
#### Logging failed login attempts to syslog
We need to set the logging driver to syslog so the host OS and Fail2Ban can see them. Add the following to your docker-compose file:
```
bitwarden:
logging:
driver: "syslog"
options:
tag: "$TAG"
```
With the above settings in the docker-compose file. Any failed login attempts will look like this in your syslog file:
`$DATE $TIME $SERVER $TAG[979]: ERROR: Username or password is incorrect. Try again. IP: XX.XX.XX.XX. Username: email@domain.com.`
You can change the '$TAG' to anything you like. Just remember it because it will be in the Fail2Ban filter.
#### Fail2Ban Filter
Create the filter file
```
sudo nano /etc/fail2ban/filter.d/bitwarden.conf
```
And add the following
```
[INCLUDES]
before = common.conf
[Definition]
failregex = ^%(__prefix_line)s.*$TAG.* ERROR: Username or password is incorrect. Try again. IP: <HOST>\. Username:.*$
ignoreregex =
```
Dont forget to change the '$TAG' to what you set it as from above.
#### Fail2ban Jail
Now we need the jail, create the jail file
```
sudo nano /etc/fail2ban/jail.d/bitwarden.local
```
and add:
```
[bitwarden]
enabled = true
port = 80,443,8081
filter = bitwarden
action = iptables-allports[name=bitwarden]
logpath = /var/log/syslog
maxretry = 3
bantime = 14400
findtime = 14400
```
Feel free to change the options as you see fit.
#### Testing Fail2Ban
Now just try to login to bitwarden using any email (it doesnt have to be a valid email, just an email format)
If it works correctly and your IP is banned, you can unban the ip by running:
```
sudo fail2ban-client unban XX.XX.XX.XX bitwarden
```
