==== Kubernetes ====

The following is a set of possible use cases for Kubernetes/Containers based on existing workflows - particularly related to CIS Undergraduate Courses.

==== Visual Studio Code ====

SoCS Students are increasingly using remote code execution through Visual Studio Code to write and test their assignments. Assignments are coded through VS Code on a students personal computer, which then connects to a remote environment in which it executes the code. This is currently typically done on the SoCS Linux/NoMachine cluster. 

It is also possible to use Kubernetes containers as a remote execution environment. This has two major benefits. 

  * Each container is run independently of any other student environments. This makes it easier to limit resources
  * As each development environment is a Docker container, it is easy to provide a customized environment for courses or even individual requirements.

Below are two VSCode Remote Kubernetes Options. 

=== Okteto Extension ===

== Instructor Workflow ==

  * Instructors will define the software required for their course/assignment/project.
  * SoCS IT will build a Docker Container based on these specifications.
  * A customized yaml file will be provided to each student which defines their work environment to use the specified Docker Container. See an example below.

<code>
name: socslinux-test
image: socsguelph/socslinux:latest
autocreate: true
workdir: /tmp
command: ["bash"]
namespace: vscodetest
volumes:
  - /root/.vscode-server    # persist vscode extensions
securityContext:
  capabilities:
    add:
    - SYS_PTRACE
persistentVolume:
  enabled: true
  storageClass: nfs-client
</code>

== Student Workflow ==

First set up the dev environment to install the extensions and configuration files required to connect to Kubernetes. These steps only need to be done once.

  * Install the Okteto Extension in VSCode.
  * Download the Kubeconfig and add to local machine. 

Set up the project. This needs to be done once for each project.

  * Create a folder/git repo to hold code, and add the above yaml file to it. 
  * Create a namespace in Kubernetes to work within.

Daily Workflow.

  * Run Okteto Extension from within VSCode to connect to remote environment
  * Code and Test
