Docker Level 1 Test

Docker
#1

In one of the question they are asking to create docker network.
I am using below command to create network.
[tony@stapp01 ~]$ docker network create
–driver=bridge
–subnet=182.18.0.1/24
–gateway=182.18.0.1
mysql-network

It gives me below error:

Error response from daemon: invalid network config:
invalid subnet 182.18.0.1/24: it should be 182.18.0.0/24

Please help.

#2

If you read the error message it says the subnet should be 182.18.0.0/24 not 182.18.0.1/24

Yes, but they are asking ( in a question ) to use this subnet 182.18.0.1/24 only, if I am using 182.18.0.0/24 it system says wrong answer.

Thank you, but I have already cleared the test so, I think I will not be able to perform again.
