Since Eucalyptus is coded in python, I spend the past week going through online tutorials and learning more about how to code in python. In comparison to any programming languages I have used before, the syntax is very straight forward and easy to comprehend and learn. It may be that python isn’t by far the first programming language that I have learned, or that it is just an easy to learn language in general. Im going to continue with the tutorials I have been using and hopefully understand most of what is going on in the Eucalyptus code so I can contribute to commenting it.
In addition to learning python, I also had to redownload and initialize Euca2ools on my new laptop. This time was actually much more successful than the first time I attempted doing this. I couldn’t figure out how to download the credentials .zip from our matrix cluster yet, so I tested this process out with the ECC credentials. I was able to initialize, create a key pair, find an image, and create an instance of it. In addition to that I was also able to assign that instance an availible IP, SSH into it, and terminate the instance using euca2ools. I did have to use a few extra commands in order to make the process from our euca2ools wiki page work, which i later added in.
This is how you can generate an accessible instance IP:
euca-allocate-address
Associate the allocated address with your VM instance:
euca-associate-address <IP from allocate> -i <instance ID>
Last monday I was put on the task of figuring out how to get multiple people the permissions to receive user requests and approve them. After some research and playing around with our matrix graphical interface I couldn’t figure out how to get multiple users the ability to do that. So as of right now, the only way that I know how to have multiple people receive requests is to give them all access to the email address the requests get sent to. If we wish to have professor Wurst have access to user requests, then we will either have to make a new email address that our “Administrators” can access, or just switch the email address to professor Wurst’s so he will receive them.
Now that I have a better understanding of python and euca2ools, I plan on getting to know more about eutester and how that area of our project works. I also plan on looking at more of the Eucalyptus code to see if I can start commenting parts of it. But more of that stuff soon enough! I’m looking forward to this coming week and seeing where our next step is as a class.
