Proxy thread unable to start: Address already in use

[rb1whitney]

I am trying to run the example piece of code given for chef-provisioning-docker using chef zero. When I try to run it appears that Chef is already listening on port 172.17.0.1 port 8889 and causing the code the inability to use 172.17.0.1 to communicate from the container to the host. Is there something I need to do to resolve this issue?

Output:
Starting Chef Client, version 12.9.38
...

• machine_image[ssh_server] action create

• update node ssh_server at chefzero://localhost:8889
  ...
