Bug 1687227

Adding relevant upstream docs: https://docker-py.readthedocs.io/en/stable/api.html?highlight=init#docker.api.container.ContainerApiMixin.create_host_config

Your customer specifically asks to update docker-py to a newer version: we can't do that because there was a major backwards incompat change between docker-py version 1 and 2.

I will backport the init parameter.

# rpm -q docker python-docker-py
docker-1.13.1-96.gitb2f74b2.el7.x86_64
python-docker-py-1.10.6-9.el7_6.noarch

#docker pull busybox
#updatedb
#locate docker-init
/usr/libexec/docker/docker-init-current
/usr/libexec/docker/docker-init-latest

# cat init.py 
import docker
c = docker.Client()
x = c.create_container('busybox', 'ls', host_config=c.create_host_config(init=True, init_path="/usr/libexec/docker/docker-init-current"))
print x
print c.inspect_container(x)
