-e CPU_TEMPERATURE_TRESHOLD= \
-e CHECK_INTERVAL= \
--device=/dev/ipmi0:/dev/ipmi0:rw \
tigerblue77/dell_idrac_fan_controller:latest
```
2. with LAN iDRAC:
```bash
docker run -d \

## Parameters
All parameters are optional as they have default values (including default iDRAC username and password).
- `IDRAC_HOST` parameter can be set to "local" or to your distant iDRAC's IP address. **Default** value is "local".
- `IDRAC_USERNAME` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "root".
- `IDRAC_PASSWORD` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "calvin".
- `FAN_SPEED` parameter can be set as a decimal (from 0 to 100%) or hexadecimaladecimal value (from 0x00 to 0x64) you want to set the fans to. **Default** value is 5(%).
- `CPU_TEMPERATURE_TRESHOLD` parameter is the T°junction (junction temperature) threshold beyond which the Dell fan mode defined in your BIOS will become active again (to protect the server hardware against overheat). **Default** value is 50(°C).
- `CHECK_INTERVAL` parameter is the time (in seconds) between each temperature check and potential profile change. **Default** value is 60(s).
