Final Exam Technical Notes
A user must have Admin access to a repository on GitHub for CircleCI integration. The Final Exam GitHub Classroom repositories were not set up that way and there is no way for me to edit the assignment and add that back in. So I have to manually change it for each repository. Of course, I cannot do that until the repository is created. I will check occasionally. If you need it allowed earlier, let me know.
Note: Your day and time will be different.

Announcement: Azure Practice Exam
I did not have access to these materials (slides, walkthroughs, review questions) when I prepared for the Certification Exam. I went through the Online AZ-900 Learning Paths (Scroll down the page until the “Two ways to prepare”), which you can consult for background.
Exercise 98: Azure Crossword Questions
As you go through the material and practice quizzes create questions and answers for an Azure Crossword. On the Google Form add at least 2 answers and questions for the crossword. Your question/answer pair must be unique. Try not to repeat any current answer, and if you do, you must come up with a unique question.
One source is questions on the quizzes that you missed or terms you did not know.
I posted this exercise first to keep this in mind as you go through the material, but I suggest completing it last.
Exercise 99: Azure Module 02 Review Questions
All module review questions allow multiple attempts.
Yes, I did forget to assign this when we covered the slides (and already had it made up).
Exercise 102: Azure Practice Exam
After I went through the Online AZ-900 Learning Paths, the way that I prepared was through practice exams.
See the separate post for information on how to access them.
To verify your Practice Exam set up, submit a screenshot of a single question from the practice exam.

Announcement:
IT here at UA is conducting the Certification Exam. They will conduct the via a VM from Centiport. IT reserves VMs from Centiport for specific time slots and a limit on concurrent test takers.
The Certification Exam will take place during Finals Week. Your schedule and these many constraints make scheduling of this non-trivial. Our course assigned Final Exam time is Wed, Dec 9 from 12:15 - 1:15 pm. However, these do not align perfectly with when we can schedule the Certification Exam, and there may be a limit as to how many students can take the exam at the same time.
Please do the first exercise right away, by midnight today (Mon Nov 23) at the latest, to figure out availability.
Note that it will not harm your grade in the course if you do not pass the Certification Exam. However, you do need to complete the Certification Exam.
The Final Exam is a take-home exam and will not have a specific class meeting. The only specific time that you need to be available during Finals Week is for the Certification Exam.
Exercise 93: Availability for Certification Exam
Complete first. Due by Mon Nov 23 11:59:59 pm at the latest.
You can edit your response for a day or two. After that directly inform me via email of any availability changes.

Week 13 Class 37 Wed Nov 18 Posted: Nov 18
We continue to explore Azure. This time, we have some Walkthroughs (i.e., labs) to perform. The training materials I have from Microsoft say to use these as demos (i.e., I would make a screencast) or labs. They are relatively easy to follow, and I think you would prefer running through them yourself.
The Walkthroughs and the Review Questions are direct from Microsoft. Not that educators are perfect, but companies tend to be a bit sloppier in training materials. Also, note that there is one best answer in the Review Questions and then on the Certification Exam.
Some of the walkthroughs require an RDP client to connect to Windows. For macOS, you can download Microsoft Remote Desktop.
Use the region US East. For me, many of the default regions were in Australia.
The instructions for the Walkthroughs all end with advice on deleting the resources. Make sure you do so as a) You don’t want to use up your allowance b) In some cases, you are limited in concurrent use of a type of resource.
For each exercise, there is a Brightspace assignment to upload a screenshot(s). The screenshot should verify that you went through the Walkthrough and got it running. Part of the assignment is figuring out what that would be. Multiple screenshots are allowed for each exercise.

Today we start on Azure Fundamentals. As a reminder, this material is provided by Microsoft towards the taking, and hopefully passing, the AZ900 Azure Fundamentals Certification. In exchange for the class going through this material, all students receive a chance to take the AZ900 Certification Exam for free.
John Corby, the CIO (Chief Information Officer) of UA, approached me about this late last Spring. I went ahead with it because:
To present this material, I taught myself the topic and took (and passed) the same certification exam you will be taking.
Microsoft provides the slides and labs. I will point out any changes that I make. I see Microsoft’s goals as a) generating more people who understand cloud in general and Azure in particular, and b) seeing how the notes and material could be improved.
I will discuss the Certification Exam later. The class will take the online exam during the last week of classes, and you will receive credit for taking the exam, even if you do not pass.
If you have any questions or issues, please let me know. Questions are particularly crucial as these are not my notes, and this is the first time we are using this material.

Today’s overall goal is to get Jenkins using Docker to build on a different Linux distribution than the one Jenkins is using.
We almost get there. All we have to do is to change the agent in the pipeline. We need to install a Docker plugin for Jenkins. Unfortunately, the plugin server for Jenkins was down all of Thursday and still not up at this time.
Once that is up, we are very close to building in a Docker container on a per-distro basis.

Screencast: Jenkins Setup
On Sunday, I was setting up so that ports, such as 8080, were open on the class server. That way, you could run your Jenkins in a container on the class server and get access to it via a web browser. To do so, I have to manage ports. There are many ways to manage ports, but I chose ufw . When I set it up, it warned me about ssh sessions, but I did not think about it.
So I enabled ufw to manage ports. By default, ufw blocks all ports. I enabled port 8080 and was able to see in my local browser Jenkins running in a container on the class server.
Later that night, watching some TV, I noticed the Discord messages about the class server being down. I quickly realized what I had done. I had blocked the SSH port. Luckily, I had an open ssh session to the class server as root and was able to open it back up quickly.
When you will do something that could affect SSH, they always say to have an open SSH session as root running. I know that Linode has another way into the machine (that bypasses the restrictions), but that would take a lot more time.
Exercises 77 & 78: Jenkins Setup
Get Jenkins running in a container and add a project from a GitHub URL. Jenkins can be in a container on your local machine, or you can use the class server (see notes on this below).
In the screencast, I forgot to run the command with a named volume, so be sure to do so:

Screencast: Hub: Git & Docker
When you connect a GitHub account to a Docker Hub acccount, if you have access to a repository on GitHub, then the Docker Hub account has access to it, including those of organizations you belong to (i.e., work). Better to use a separate account.
My accounts used in the screencast:

I swear that it will kill the job if you exit a remote system unless you use nohup. It just takes a while to do so, so I could not demo that in the screencast. Besides, with a critical, long-running program, you do not want to take a chance.

Exercise 49: Demo CMake File
If you are writing a program and go to use part of an API that you are not sure about, you can add it to your program and write a series of output statements (or assertions) to check the results. The problem with this is that it makes the overall program more complicated. It is easy to get confused because you are mixing the large program’s behavior with understanding the API’s behavior. The behavior that you observe is dependent on the behavior of the large program and the behavior of the API you are trying to use. In good design we try to isolate dependencies.
So when I investigate or present parts of an API, I write small, focused programs whose only purpose is to use the API. For example, if I am not sure how a particular part of std::vector works, I write a small C++ program to try it.
We can do the same with CMake. Below is the start of a small demo program for
get_filename_component().
Create an empty directory, copy this file into it, and run cmake. You can even run cmake “in-source” because there is not any “source”.
For this exercise, finish this demo example for all options of get_filename_component(). Replace the hard-coded filename with the filename from the crossword questions in Exercise 50.
Upload your CMakeLists.txt to DevOps Exercises 49: Demo CMake File
Exercise 50: ctest Crossword
Crossword answers can include underscores (‘_’) for multi-part names, and slashes (‘/’) and periods (‘.’) for filenames.

Announcement:
We have three screencasts today, all devoted to CMake. Since they ran for almost 50 minutes, there is no exercise to enter the examples.
However, there is Project 1, where much of this is useful.
Screencast: CMake Source Directories
I struggle with good naming and directory structure. For srcML, I considered:
src
├── client
└── libsrcml
test
├── client
└── libsrcml
(a)
client
├── src
└── test
libsrcml
├── src
└── test
(b)
client
└── test
libsrcml
└── test
(c)
Choice (a) separates src and test first, (b) separates by application first, and (c)
the source files are not in a subdirectory, but the tests are.
We went with (a) as it fits the build files better (more on that later).
I would have named the client the client’s name, srcml, but thought that may be
confusing as it is the name of the entire thing.
Another decision: test or tests?

Screencast: Project 1 & Project 2
Motivation: Jekyll is a static website generator closely associated with GitHub Pages. Besides fixed .html pages, it is the most common way to create a GitHub Pages website. Jekyll generates the website you are looking at now.
Jekyll supports data files in the text data formats YAML, JSON, CSV, and TSV. I recently had to convert srcML documentation pages from an XML format to one of these data formats (JSON or YAML). This conversion was much more difficult than I expected. After much searching and experimentation, I first converted to JSON, manually fixed the JSON, and then converted it to YAML. In addition to the manual work, this involved multiple tools and multiple dead ends.
Screencast: CMake Object Libraries
Note: Seems on some platforms (WSL2?) CMake doesn’t pick up that the Object library needs to compile with -fPIC. So add the following to your srcmlxpathobj target:
set_target_properties(srcmlxpathobj PROPERTIES POSITION_INDEPENDENT_CODE ON)
Exercises 45 & 46: CMake for SEComplexity
Create a CMake build for SEComplexity. You can start with your CMakeLists.txt that has both shared and static libraries.
Then, create a showterm session where you generate, build, and run with a Debug build and then with a Release build.
Upload your CMakeLists.txt and showterm URL to DevOps Exercises 45 & 46: CMake for SEComplexity (Not to Brightspace).
Screencast Folder: Class 19 Wed Oct 07
Exercise Due Date: 4 pm on Thursday, Oct 08
Reminders:
Project 1 is due by 11:59:59 pm Friday, Oct 16 Monday, Oct 19.
There are multiple text data formats, including XML, JSON, CSV, TSV, and YAML. Conversion between these formats is not as easy as it should be. Some tools only include two of these formats. Many tools are not customizable and make conversion decisions that do not reflect an understanding of the formats.
The markturn project is a conversion program for text data formats, e.g., XML, JSON, and YAML. It is a command-line program and corresponding library that allows easy conversion between data in these formats. The ultimate goal is to provide customization so a user would not have to use multiple tools when converting between these formats. And, of course, the program is a platform for additional text data formats.
The project is just starting, with mostly skeleton code. I.E., many of the files are there but are unimplemented. Regardless, the necessary files exist, and the dependencies on external libraries are in place.
You can get your repository through the GitHub Classroom link on the Brightspace page.
The project does not currently have a build. Developers are entering build commands manually. So you are to create a CMake build for the project. This build is to accomplish the following:
tgz, zipI will update the code throughout the project as I implement more parts of the code. These updates are in the form of pull requests so you can control when they are part of your repository. At the end of the project, all pull requests must be accepted.
As you create this, keep in mind the following:
Project 2 is due by 11:59:59 pm on Friday, Oct 23 Monday, Oct 26.
The markturn project is going ahead with development. Someone is creating an automated build using CMake.
What is missing are environments to build the project.
Create Docker files that will provide containers for the markturn project. The project needs containers for the following platforms:
The idea behind this mix is a stable, long-term version and the latest version to prepare for the future.
A GitHub Classroom repository is available for you to work on these. You are encouraged to use as many different images as you need for the project.

Announcement: Using the bind mount, we used a subshell for the pwd command, as in:
docker run --mount type=bind,source=$(pwd),target=/srcComplexity,readonly
At one point, I briefly mentioned that examples of this had quotes around the subshell. I have not been doing that, even in the screencasts for today.
However, I ran into a problem with pathnames that contain spaces. Ironically enough, when running your CMake files from the previous class:
invalid argument "type=bind,source=..." for "--mount" flag: target is required
as the path, i.e., /Users/collard/Library/Mobile Documents/ contains spaces.
From now on, I will use double quotes around the subshell when it produces a path/filename:
docker run --mount type=bind,source="$(pwd)",target=/srcComplexity,readonly ...
Note that the problem here is not the subshell, but that it returns a filename that may contain spaces.
Exercise 42: CMake Static Library
Create a CMake build for SEComplexity that creates and links only to a static library.
Enter it in steps, and check what occurs on each step.
Upload your CMakeLists.txt to Brightspace.
Exercise 43: CMake Shared Library
Create a CMake build for SEComplexity that creates and links only to a shared library. This CMake file does not include the static library at all.

So the Makefile tab issue. I was getting your Makefiles by going to the form and copying it off the form in the browser. I then tried downloading a CSV file of your submissions. That fixed many of them, but not all. To summarize, with “Correct” meaning a tab and “Incorrect” meaning spaces:
One lesson from this is to be careful with how you copy/exchange files. Keeping it in file form is always best.

Please check the feedback for Exercises 33 & 34 Makefile. Multiple students (but not all) had
spaces instead of tab indentation. I had to run the Makefile through unexpand to fix them. This issue may be due to how you
copy/paste it into the form. Just make sure that that the Makefile in your directory works.
There are a couple of ways to go through the material for today. View both screencasts, then do the crossword (which involves both), then do the Makefile exercises. Or do the Makefile exercise as you finish the corresponding screencast. Whatever you do, follow the order of static then shared.
I am not entirely confident in how well I prepared you for today’s Makefile exercises. If you have any questions or confusion, please contact me. It will help your answer and benefit the class as this affects what I post on Wednesday.
Exercise 35: Static Library Makefile
A reminder that your previous Makefile (from Exercises 33 & 34) did the following:
make - Runs srcComplexity (uses the first target by default)make run - Runs srcComplexity with an example filemake clean - Cleans up generated filesTake that Makefile (from Exercises 33 & 34) and perform the following changes so that these commands run correctly:
make static - Builds program srcComplexityStatic using a static library libsrcmlxpath.amake runstatic - Runs the program srcComplexityStaticmake clean - Now also removes the static libraryMake sure that the commands all run correctly.
Note: You can add a target for static and srcComplexityStatic in the following manner:
.PHONY: static
static : srcComplexityStatic
You do not need an action for the target static. Then, create the target for srcComplexityStatic.
Upload your Makefile to DevOps Exercises 35 Static Library Makefile
Screencast: Shared Libraries showterm Session
Appears the last minute is messed up. A sync problem in the edit(able) version. Here is the text of the last minute:
I should also point out here that there are many libraries. Where you cannot get the code or get the libraries with the dot, you have an -fpic run on them or the option when they were compiled in that’s one reason we sometimes have to build libraries from scratch if you’re using them in other applications.
Okay. I’m going to stop now.
I was even less abrupt in this one.
Exercise 36: Shared Library Makefile

In DevOps, there are a large number of new technologies with associated special-purpose languages. One term used for this is DSL (Domain Specific Language). Just with Docker, we use general Unix & bash commands, Dockerfile instructions, docker (CLI) commands, and will eventually use Docker Compose declarations. And this is only one technology in the course.
To be successful, do the following:
Style is very important. I have never seen Dockerfile instructions, e.g., “RUN”, in lowercase. I had assumed that these instructions must be uppercase. In the Dockerfile exercise, some of you did not use uppercase. Yes, it worked, but it did not follow the style, and if you were applying for a job and wrote them that way, they would not hire you.
So follow the style you of the examples and documentation:
Doing so is even more critical than with source code. In DevOps, we tend to:
A brief overview of using CMake using sortDevOps as an example:
/sortDevOpsMany Makefiles assume an in-source build where the generated object code, libraries, and executables are created in the source directory
CMake is typically used with an out of source build where the generated files are in a separate directory from the source. This separation:
make cleanCreate a build directory. Typically these are at the same level as the source
and have a name based on the source directory name, e.g., /sortDevOps-Build.
Invoke the cmake command to generate the Makefile

Screencast: Build Image Part A showterm Session, SimpleDockerfile Repository
One thing I should have mentioned is that tokens (as with dockerhub) allow a more restricted access an account than a password. E.g., a token cannot be used to change a password. This follows the “principle of least privilege”. I.e., we only need to pull and push images, not change the account.

Screencast: Running Docker showterm Session
I am trying something new with this screencast. The screencast is a video of me narrating a showterm session. You can also view the showterm session directly (with no audio, of course). Note that the timing is not quite the same as the video is edited, and sometimes showterm is paused as I discuss the command. If you have trouble seeing the commands, refer to the showterm session.
Exercise 21 & 22: Demonstrate the docker commands used in the Running Docker screencast. This assignment counts as 2 exercises.
Use showterm to record your session. Install showterm on your local machine (highly recommended) (see showterm.io for installation instructions, or use the class server (accounts class1, class2, .., class5).
Your session does not have to be perfect. You can mess up commands, etc. Also, don’t enter my mess ups. Note that you can copy and paste from my showterm session, but I suggest you limit it to URLs. Entering the commands will help you to understand and remember them. You may want to follow in the showterm Session as you can move around the session much more easily.
To start your recorded session:
showterm
To end a recorded session, use a “Control-D” or type:
exit
I suggest you first experiment recording a showterm session with just a few simple commands.
After recording your showterm session, a URL of the form http://showterm.io/… will appear. Upload this URL to DevOps Exercises 21 & 22 Running Docker Session
Make sure to view your session via the URL (enter it into a browser). If you want to break this up, you can create multiple showterm sessions. Just make sure to give me all the URLs.

Multiple students had issues today with SSH agent forwarding. It appears to boil down to whether you had an ssh-agent running or not.
Suppose you are on a UNIX-based OS using a GUI (Linux desktop, macOS). Then ssh-agent is automatically set up and running. If you are using Linux on a server or WSL, then the ssh-agent is not automatically setup.
So, you have to set them up. The commands to do so are in the notes
