Can't run the docker example

[rajiknows]

i cloned the repo and was going through the code , i decided to run the example and see ....

  cargo run --release --example docker
    Updating git repository `https://github.com/peterhuene/bollard`
error: failed to load source for dependency `bollard`

Caused by:
  Unable to update https://github.com/peterhuene/bollard?branch=nodes-api

Caused by:
  failed to find branch `nodes-api`

Caused by:
  cannot locate remote-tracking branch 'origin/nodes-api'; class=Reference (4); code=NotFound (-3)

can someone help me out , guess there is issue related to pulling the fork of bollard
