Workshop about Docker! https://ibm.github.io/docker101/

Docker

Series of labs and instructions to introduce you to containers and Docker. Learn to run a container, inspect a container and understand the isolation of processes, create a Dockerfile, build an image from a Dockerfile and understand layers, tag and push images to a registry, scale and update containers, and more.

docker101's Issues

Broken link to gitbook lab

Link in README https://ibm-developer.gitbook.io/docker
should be
https://ibm-developer.gitbook.io/docker101/

Rename the repo to Docker

Rename the repo to “docker”? The gitbook converts different levels of the workshop, as defined in SUMMARY.md to sections: docker 101 section; docker 102 section; docker 201 section; some of these can/will be more than "intro to docker"

Incorrect Python Script in Web tutorial (developerWorks)

The python script defined in lab2.md and the lab 2 tutorial in the developerWorks page appears to be incorrect.

Running the python script with python3 app.py would return an error :

File "app.py", line 1
    echo 'from flask import Flask
                                ^
SyntaxError: EOL while scanning string literal

Possible fix: update the lab2.md file in this repo with the copy found at this forked repo, and update the tutorial page as well for future students...

Port 5001 not exposed in the Dockerfile

You gotta add:
EXPOSE 5001

To your Dockerfile or else you'll get a Refused connection
