 Alternatively, you can use the [docker image](https://hub.docker.com/r/shizunge/endlessh-go):
 
 ```
-sudo docker run -d -p 2222:2222 shizunge/endlessh-go -logtostderr -v=1
+docker run -d -p 2222:2222 shizunge/endlessh-go -logtostderr -v=1
 ```
 
 It listens to port `2222` by default.

 The GeoIP Database will be saved in a mounted volume in: `./geo-data`. And the endlessh-go container will use this database to do the location lookups.
 
 This example exposes the following ports. Except the SSH port, you should not expose other ports to public without protections (not included in this example) in production.
