Python script to run docker containers

Question

I want to write a python script that run docker containers and then show logs for that particular container, I have use some functions that are working and starting or stoping containers for me. Can somebody help me to show logs for the containers ?? I tried to use container.logs() function, but it is not working for me, i am also trying to study docker-py library ! I don't know much about python, any help will be highly appreciated !

#!/usr/bin/python
import docker
c = docker.Client(base_url='unix://var/run/docker.sock',version='1.12',timeout=10)
ctr = c.create_container('ubuntu:16.04') 
c.start(ctr)

which version of docker are you using? You are using old python client it seems — Tarun Lalwani, Sep 11 '17 at 07:38

You are using a old docker client. Run below to fix that

pip uninstall docker-py
pip install docker

Once done you can use something like below

import docker

c = docker.DockerClient(base_url='unix://var/run/docker.sock',timeout=10)
ctr = c.containers.run('ubuntu:16.04',command="bash -c ' for((i=1;i<=10;i+=2)); do echo Welcome $i times; sleep 10; done'", detach=True) 
logs = ctr.logs(stream=True)

for line in logs:
    print(line)

Please test it in a fresh new virtual environment, the code has been tested on my end and then only shared. The code has nothing wrong. Please us https://virtualenvwrapper.readthedocs.io/en/latest/ – Tarun Lalwani Sep 11 '17 at 11:42
