# IDRAC Fan Controller Docker Image

- `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 hexadecimal value (from 0x00 to 0x64) you want to set the fans to. Default value is 5(%).
- `MAXIMUM_TEMPERATURE` parameter is the 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 32(°C).

To use:

  --restart unless-stopped \
  -e FAN_SPEED=<dec or hex fan speed> \
  -e MAXIMUM_TEMPERATURE=<dec temp treshold> \
  alombardo4/idrac-fan-control:latest
```

2. with LAN iDRAC:
