Install Docker BCode. This is a copy of Charlie's development environment in a Docker container. It is based on the official Docker image for Ubuntu. It is a bit like having Pristine Lubuntu in a Docker container.
For now, it should be:
docker pull charliecalvert/bcode:bcoder
Confirm that it downloaded:
Create a container and run it:
docker run -it charliecalvert/bcode:bcoder
You are placed at the root of the container logged in a the super user:
That is the way we create a new container and use it. Below I will explain how to start an existing container.
We don't want to be super user. So become bcuser and navigate to the git dirctory:
su bcuser gd ll
As you can see, the aliases used by JsObjects are loaded, and JsObjects itself is installed.
For the next step, you need to know the IP address of your copy of Pristine Lubuntu. Open up a new bash tab and type the following:
ip addr | grep inet
You will see several lines of output. One of them contains your IP. The line you want might start a bit like this:
inet 192.168.2.26/24 ETC
In this case 192.168.2.26 is your IP address.
No go to the .ssh directory in the container and copy your private key from Pristine Lubuntu. You will need to modify the following line of code to use your IP address:
scp bcuser@<YOUR IP HERE>:/home/bcuser/.ssh/prog272-key .
Create a symbolic link to it:
ln -s prog272-key main-key
Load it: sshadd
While we are at it, type cd to get to your home directory and copy your .gitconfig into the home directory of your container. Again, you will have to put in your IP address:
scp firstname.lastname@example.org:/home/bcuser/.gitconfig .
Remember to type in your IP address. Use nano to edit your .gitconfig and change your name to reflect that you are in a Docker container.
[user] email = email@example.com name = Charlie on Docker BCode
NOTE: You may need to install nano:
sudo apt-get install nano
Go back to the Git directory and clone your repo:
gd git clone firstname.lastname@example.org:username/prog272-lastname-2019.git
You will, of course, have to modify the Git URL.
Make several changes to your README.md file from your repo both in the container and in Pristine Lubuntu. I want to be able to see changes in your Git log showing you made changes in both places.
Once again, lets use the Docker Starter assignment to walk us through these steps.
Get the container name from the Docker Starter.
Start and exec the container.
Mostly I will be looking at your at the log for your repo with this command: git log. However, also include one screen shot showing that you are logged into the container and inside your repo. I'm hoping to see a screenshot with something like this in it:
