Conu

New Features

* Docker image now have method `run_via_api()`
* We have introduced OpenShift `origin` and Kubernetes `k8s` backends.
* Support for three k8s primitives - `Pod`, `Service`, `Deployment`
* CentOS CI, thanks to jpopelka
* Docker backend now has `push()` and `login()` methods
* Origin backend has `oc_new_app()` method
* Automatic updates of dependencies using [kebechet bot](https://github.com/thoth-station/kebechet), thanks to fridex
* Codacy hook, thanks to lachmanfrantisek
* Examples for origin and k8s backends

Fixes
* [Use Popen in run_cmd and pipe outputs to logger](https://github.com/user-cont/conu/pull/263), thanks to SkullTech

Breaking changes

* We have changed behavior of `.get_metadata` method. It now returns an
instance of `Metadata` class. Method `.inspect` is meant to return raw data
of the selected backend.

New Features

* Introduction of a new class to hold [container and image
metadata](https://github.com/user-cont/conu/blob/d19accbbc82b7a04090fc6339f4974c73f2987d6/conu/apidefs/metadata.pyL4).
In coming weeks, we'll be working on integrating this class into the library.
Our main intent is to make the Metadata class generic across all backends.

[204](https://github.com/user-cont/conu/pulls/204),
[207](https://github.com/user-cont/conu/pulls/207))
* conu now has an API to access image layers ([207](https://github.com/user-cont/conu/pulls/203))
* We've added [Contribution guide](https://github.com/user-cont/conu/blob/master/CONTRIBUTING.md), thanks to Rado Pitonak ([208](https://github.com/user-cont/conu/pulls/208)).

Fixes

* Provide docker container filesystem using `docker export` instead of `atomic
mount` — conu no longer requires
[atomic](https://github.com/projectatomic/atomic). This also means that root
privileges are no longer required.
* Don't depend on `enum34` for python 3, thanks to Rado Pitonak ([214](https://github.com/user-cont/conu/pulls/214))

New Features

* Introduced fixtures and helper functions to simplify container testing.
* Support was added for another backend - nspawn.
* It is possible to decide cleanup policy when initializing backend.
* Methods for listing containers and images were added to both supported backends.
* Image mounting is possible also without superuser privileges.
* To represent and work with docker volumes, there is a new class `Volume`.
* `run_via_binary` accepts commands in form of list of strings
to make running images more intuitively.
* It is possible to build image from Dockerfile using `DockerImage.build()`.
* There is a new method to check GPG signatures of RPMs in images.
* Documentation is updated, there is also asciinema demo in README.md.

Please note, that our API is still not marked stable yet.

Breaking changes

* We have changed how `logs()` method works. It now returns iterator always. On
top of it, we have implemented more convenience methods to return logs as
bytes and unicode.

* Backend class can (and should) be used as a context manager. This was done
for the sake of creating a temporary directory meant for the backend
instance. The context manager ensures the temporary directory will be removed.

New Features

* We added support for docker-py version 1 so it can work in CentOS.
* conu will check whether required binaries are present and if not,
`CommandDoesNotExistException` will be raised.
* Our documentation was improved and contains now more examples and the python
interface should be explained in more detail.
* When creating docker containers, conu now utilizes option `--cidfile`.
* `execute()` method can be blocking and non-blocking.
* Backend provides a new methos `cleanup_containers()` to cleanup containers
created during the session.

* Initial release.
