### Parse Docker Image

```python

>>> from docker_image import reference

>>> 

>>> # with registry, repo, tag, and digest

>>> ref = reference.Reference.parse(

...     'daocloud.io/nginx:1.11-alpine@sha256:14bf491df1d58404433b577e093c906460871ee677d18caa276d9c03727e0b33'

... )

>>> print ref

{'tag': '1.11-alpine', 'name': 'daocloud.io/nginx', 'digest': 'sha256:14bf491df1d58404433b577e093c906460871ee677d18caa276d9c03727e0b33'}

>>> 

>>> # with registry and repo

>>> ref = reference.Reference.parse(

...     'daocloud.io/nginx'

... )

>>> print ref

{'tag': None, 'name': 'daocloud.io/nginx', 'digest': None}

>>> # get registry hostname

>>> hostname, name = ref.split_hostname()

>>> print 'hostname: {}, name: {}'.format(hostname, name)

hostname: daocloud.io, name: nginx

>>> # with registry, repo and tag

>>> ref = reference.Reference.parse(

...     'daocloud.io/nginx:latest'

... )

>>> print ref

{'tag': 'latest', 'name': 'daocloud.io/nginx', 'digest': None}

>>> # with repo and tag

>>> ref = reference.Reference.parse(

...     'nginx:latest'

... )

>>> print ref

{'tag': 'latest', 'name': 'nginx', 'digest': None}

>>> # only repo

>>> ref = reference.Reference.parse(

...     'nginx'

... )

>>> print ref

{'tag': None, 'name': 'nginx', 'digest': None}

>>> ref = reference.Reference.parse_normalized_named(

...     'containous/traefik'

... )

>>> print ref

{'name': 'docker.io/containous/traefik', 'tag': None, 'digest': None}

>>> hostname, name = ref.split_hostname()

>>> print 'hostname: {}, name: {}'.format(hostname, name)

hostname: docker.io, name: containous/traefik

```
