Today I used as the blog post as a starting point https://libcloud.apache.org/blog/2016/02/05/libcloud-containers-example.html. I came across a couple of issues with the example code that meant it didn't work. I have made some small changes to your example to get it to work. I also found that the install_image(path) method sometimes gets a JSON parsing error due to the docker API streaming multiple new line limited json messages. By adding the check if the image has been downloaded allows it to be rerun again and the deployment will work. With the docker image tomcat:8.0 you need to provide a command parameter in deploy_container call otherwise the container starts and immediately stops. Will continue to evaluate as it looks like it will be very useful.  

Code for my working example below:  

from libcloud.container.providers 
import get_driver from libcloud.container.types
import Provider
driver = get_driver(Provider.DOCKER)
docker_driver = driver(host='https://198.61.239.128', port=4243, key_file='key.pem', cert_file='cert.pem')
path='tomcat:8.0'

# Check to see if image already downloaded 

image = None 
images = docker_driver.list_images() 
dl = [ dl_image for dl_image in images if dl_image.path == path] 
if len(dl) > 0:
  image = dl[0]

if image is None: 
  # Need to download & install 
  image = docker_driver.install_image(path) 
bindings = { "22/tcp": [{ "HostPort": "11022" }], "8080/tcp": [{ "HostPort": "18080" }] } 
container = driver.deploy_container('my_test_container', image, command='catalina.sh run', port_bindings=bindings)
