Lab A - Build Software

Goals

We’ll setup a CI Pipeline with source code tests, build, and then push the artifact to a remote repository!

Steps

1. In Harness:

   click:	#
   Projects (blue bar)	1
   Your Project: ?project	2

   

2. If you see the Welcome screen with Get Started pane, kick it to the curb with the “X” top right.

   Create the pipeline

3. In your project:

   click:	#
   Projects (blue bar)	1
   Your Project: ?project	2

4. In the box that pops up:

   click:	#	value
   Name	1	Python Build
   Inline	2
   Start	3

   

   Inline vs. Remote

   We’re using inline for this lab, but you can also use a remote repository like GitHub. This is useful for teams that want to keep their pipelines as code bundled up snuggly with application code. Cozy!

5. then:

   click:	#
   Add Stage	1
   build	2

   

6. then: 1 enter any name (ex: build), 2 ensure Clone Codebase is selected, 3 click for repo selector and pick harnessrepo, 4 click Set Up Stage

   Configure the infrastructure and tests

7. On the infrastructure page: 1 click Cloud, 2 click Continue

   Harness Cloud is the BESTEST cloud

   Something awesome happened right there. With zero configuration (well ok… ooooooone click!) you instantly configured an autoscaling build environment in the cloud that requires no management on your part and is dramatically less expensive than on-premise. Plus Harness is using the fastest bare-metal hardware in the Solar System. Seriously. Astronauts checked.

8. On the execution page: 1 click Add Step, 2 click Add Step

9. In the Step Library: 1 (optional) type tests in search box, 2 click Run Tests

10. In the Run Tests pane: 1 name the test Run Tests with Intelligence, 2 choose python, 3 Pytest, 4 Click Additional Configuration to expand…

    …5 copy and paste the install command below into the Pre-Command field…

    pip install pytest & cd ./python-tests

    … then: 6 click Apply Changes

    Leverage a template for software build!

11. Back in the Execution pane: 1 click Add Step, 2 click Use Template

12. In the Template Library: 1 click Compile Application, 2 click Use Template (far bottom right of screen)

13. In the template box: 1 name the template Compile, 2 click Apply Changes

    Save the completed build artifact

14. Back in the Execution pane: 1 click Add Step, 2 click Add Step

15. In the Step Library: 1 type docker in search box, 2 click Build and Push an image to Dockerhub

16. In the Build and Push pane:
    1 name the step Push to DockerHub
    2 select dockerhub for Docker Connector
    3 for Docker Respository paste:

    nikpap/harness-workshop

    4 click +Add in Tags, then paste:

    <+variable.username>-<+pipeline.sequenceId>

    5 Click Optional Configuration to expand
    6 For DockerFile paste:

    /harness/frontend-app/harness-webapp/Dockerfile

    7 For Context paste:

    /harness/frontend-app/harness-webapp

    8 Click Apply Changes. That was the biggest step in the workshop, you did it! ⭐️

17. In the top right of Pipeline Studio: 1 click Save, 2 click Run

    Note

    You might have noticed an option to pick the branch before running the pipeline. We’re using main for simplicity, but it’s a great example of how this complete build pipeline could easily be reused for other branches (or repositories or services).
