vmware sandbox with docker layer , need networking help with docker /etc/docker/daemon.json

vmware sandbox with docker layer , need networking help with docker /etc/docker/daemon.json

Explorer

Hi , on my docker host machine

under /etc/docker/daemon.json has the following entries

{ "bip": "128.222.110.246/24",

"fixed-cidr": "128.222.110.246/25",

"mtu": 1500,

"default-gateway": "128.222.110.1",

"dns": ["10.253.140.73"] }

I am not familiar with IPv6 ,so I have no entries on those.

Also , I suspect something wrong with "fixed-cidr": "128.222.110.246/25",

what I want is to have the docker host machine

128.222.110.246 ( my bridge IP )

Then on the docker "guest" machine to have 128.222.110.247/24

right now it is randomly giving me a ip address of 128.222.110.2 , which is already been used by other computer.

How do I specify different "desire" ip on the guest machine. ? What I have to do in daemon.json to make that work ?

Any work around ?

How do I suggest to the sandbox building people to create a sandbox purely base on vmware ( without docker ?)

it is time consuming for me , especially when I spent 4 weeks with docker and still not successful.

I am trying to test dedupe appliance with hortonworks, I felt that I need to abandon hortonworks sandbox and go with Cloudera.
