Install Docker: 

Install Docker on a Linux VM. You don't want to install it on your computer, because it will interfere with other functions on your computer. Open a Linux VM, set the network configuration to be NAT. Download and install Docker inside the Linux VM as an admin. The remaining exercises are to be performed inside the Linux VM. Open a terminal inside the Linux VM. The following exercises won't run on Windows VM.

 There are also several YouTube videos that can be helpful in learning about Docker.

 

Part I

For the following screen shots make sure that the image includes the actual commands that were entered!

 

Question 1:

From the terminal, type in the following commands and take snapshots after running each command. 

To validate the installation is correct, type 

 $ docker run hello-world  

Provide a screen grab or snapshot of all the above information in the answer.

 

Question 2:

 Run a Busybox container. The pull command fetches the busybox image from the Docker registry and saves it to the VM.  

 $ docker pull busybox 

           Provide a screen grab or snapshot of all the above information in the answer.

 

 Question 3:

Find available docker images in your VM.  

 $ docker images 

 Check that busybox container is  

 Provide a screen grab or snapshot of all the above information in the answer.

 

Question 4:

Run the Docker container busybox. When you run the Docker image bosybox, Docker loads up the container and then runs a command in the container. When we run "docker run busybox", there is no command, so Docker did nothing and exited. 

 

$ docker run busybox 

$ 

If you provide a command after "docker run busybox", that command will be executed 

           $ docker run busybox echo "hello world from Someone" 

 Replace 'Someone' with Ogochukwu

 Provide a screen grab or snapshot of all the above information in the answer.

 

Question 5:

 Run the following command to check what containers are currently running. 

 $ docker ps  

 It should be no docker running. 

 Run the following command to see a list of all containers that we ran. Notice the STATUS column shows that these containers exited a few minutes ago. Take a snapshot. 

 $ docker ps -a  

 Run the following local host command to see the difference with and without Docker. 

 $ ps -a 

  Provide a screen grab or snapshot of all the above information in the answer
