HW3: OpenStack Exercise


  • Assignments must be completed individually.
  • Discussion is allowed (e.g. via Slack) but the submission should be made by yourself. Acknowledge your helpers/collaborators name in the submission if you discussed or got help from anyone.
  • Use an individual github repository. A repository in FutureSystems will be given later.

Create IU GitHub Account

  • Simply login https://github.iu.edu with your IU Username and Password (It is a same IU Credential that you use on other IU sites e.g. one.iu.edu)

OpenStack Command Line Tool nova

OpenStack Kilo is ready to use (as of 02/04/2016) on FutureSystems and you will have a virtual instance (server) using OpenStack Command Line Tool nova, if you complete all the tasks in this assignment. The tasks you need to complete are:

  • SSH into india.futuresystems.org and
    • enable nova command
  • Register a SSH key on OpenStack
    • rsa type

    • with default key file names
      • public: $HOME/.ssh/id_rsa.pub
      • private: $HOME/.ssh/id_rsa
    • passphrase enabled

  • Start a single instance:
    • on fg491 project
    • with a m1.small flavor,
    • a Ubuntu-15.10-64 image,
    • the registered key above,
    • and hw3-$OS_USERNAME vm name
    • Assign a Floating IP address
  • Install required software on a virtual instance
    • virtualenv
    • pip
    • ansible


Do not terminate your instance, even if you completed and submitted hw3.

Test Program

We provide hw3.py test file in your repository, checkout hw3 branch. Run this on india.futuresystems.org, if you completed all tasks above. All available tests should be succeeded without errors. First, clone your private repository from IU GitHub. See details here: IU GitHub Guidelines. You will use virtualenv to prepare packages.


bash setup.sh
source $HOME/bdossp_sp16/bin/activate

Now, you can run the test program:

python hw3.py

Completed all? You may see:

Ran 11 tests in 1.646s


Find hw3-results.txt file after you ran hw3.py python program in your current directory. Add this file in your IU GitHub repository.


Q. Where should I run the test program hw3.py? A. It is on india.futuresystems.org, not your VM instance.

Q. bash setup.sh produces command not found errors. A. Make sure you can use nova command to start a new VM like you did in the hw3 tasks. Otherwise, the test program can’t verify what you accomplished.

Q. The hw3.py test program was failed due to missing python package named lib. A. Run hw3.py in a main directory of the hw3 branch. hw3.py itself won’t work. Helper functions are required.

Submission via IU GitHub (github.iu.edu)

From now on, you will use IU GitHub to submit assignments on a private repository. IU GitHub Guidelines

  1. Clone your private repository from the course organization. You IU Username is the name of your repository.
  2. Create a hw3 branch
git branch hw3
git checkout hw3
  1. Run pull command to fetch and merge with the template repository:

    git pull git@github.iu.edu:bdossp-sp16/assignments.git hw3

  2. Sync with remote:

    git push -u origin hw3

  3. Add hw3-results.txt to your repository:

    git add hw3-results.txt

  4. Merge the template

    git commit -am "initial merge with the template"
  5. Sync your changes:

    git push -u origin hw3

Challenging Tasks (Optional)

The following tasks are optional but strongly recommended to try. These are related to Python packages and APIs (application program interface). OpenStack nova is also extended to get more experience.

‘Hello Big Data’ Flask Web Framework

Find a flask sub-directory in challange directory in your assignment repository. We provide hello.py python file and you can run the file in your VM but there are a few requirements that we request:

* Use virtualenv named 'bdossp-sp16' in your home directory
* Open a web port to the Flask application to allow access from outside


The two terms, VM or virtual instance, are exchangeable in this context.

  1. What command(s) do you run to create and enable the virtualenv?
  2. python hello.py may not work if you run only with standard python libraries. What command(s) do you run to resolve the issue? (hint. Flask is not a Python standard package)
  3. If you ran the application successfully, you can see ‘Hello Big Data’ message on your web browser with the 15000 web port. However, it is not accessible from outside e.g. http://IP_ADDRESS:15000. It is because that there is no rule for the port in OpenStack Security Group. (We assume there is no firewall here). What nova command(s) do you need to create/add a security group for the port?
  4. flask rule is provided in fg491 project. What nova command(s) do you need to see current rule(s) in the security group and to apply it to your VM?

Write your solution in the name of flask-sol.txt text file after completing the tasks above. Add this file in the flask sub-directory.
