Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

docker image ls

C:\WINDOWS\system32>docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              fce289e99eb9        4 months ago        1.84kB

Starting Images

docker run --interactive --tty ubuntu bash

or

docker run -it ubuntu bash

Then do your apt-get magic to customize the container.

Alternatively you can start and then attach

docker start xxxxx
docker attach xxxxx

Your Containers

docker container

docker ps -a

Using commit

docker ps -l
docker commit xxxxxxxx  ubuntu-vxx
docker run -it ubuntu-vxx

Installing Software on a Container

Let's say we want to configure a container - say ubuntu - with python3:

docker ps -l
docker commit ubuntu ubuntu-v01
docker run -it ubuntu-v01

Once attached work through the installations you require:

apt-get install python3
apt-get install python3-pip

Make some more changes:

C:\WINDOWS\system32>docker ps -l
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES

C:\WINDOWS\system32>docker commit dc6d36dec3c4 ubuntu-v07

C:\WINDOWS\system32>docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

ubuntu-v06          latest              c2a231c0c6ce        13 minutes ago      181MB
...
ubuntu              latest              7698f282e524        12 days ago         69.9MB
hello-world         latest              fce289e99eb9        4 months ago        1.84kB

And then use the updated version as:

docker run -it ubuntu-v07
