I currently have the need to create an image from a Dockerfile with the Python Docker SDK, and then run a container based on that image. I know how to run a container based on an image I manually create, however, when I try to use the Python Docker SDK to create the image, I can't figure out how to pass a name to the image, which I can then reference when I run a container based on the image. Looking at the docs here I don't see a parameter for name.

When I do create the image, based on the Dockerfile, using the SDK, it creates an unnamed image, however has an ID.

import docker

def main():
 folder_path = './node-sample'
 client = docker.from_env()

 try:
 image = client.images.build(path=folder_path)
 print image
 except RuntimeError as e:
 print e

if __name__ == '__main__':
 main()

This is the image it creates, it doesn't have a name: <Image: ''>

It has an ID, though: 1e3bc3e1eb43

The Dockerfile I have is super-simple, right now:

FROM node:6.14.2
EXPOSE 8080
COPY server.js .
CMD node server.js

I'd like to be able to create an image, with a name I choose, and then run a container based on that image using the Python Docker SDK.

I was able to pull out the ID from the image, and then pass that in when creating the container.

import docker
import re

def main():
 folder_path = './node-sample'
 client = docker.from_env()

 try:
 image = client.images.build(path=folder_path)[0]
 image_id = re.sub(r'(sha256:)', '', image.short_id)
 client.containers.run(image_id, detach=True, ports='8080/tcp': 8080)
 except RuntimeError as e:
 print e

if __name__ == '__main__':
 main()
