About this Hands-on Lab

In order to optimize the performance of our application, we need to check the memory allocated to the container during build time. Using a GitHub Action, we will send input and output parameters to the runner in order to insert a greeting as well as verify total memory from within the build logs.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Shell Script to Output Memory Info

In order to retrieve memory info from the container, we must create a script to retrieve this information, and then run the script on the container.

Create a Container to Run the Action

In order to run our GitHub action, we must create a container. Set up the build instructions for our container in order to run the container on our GitHub runner.

Create a Container GitHub Action

The action type must be a Container and include the following:

  • A name and description
  • At least one required input
  • At least one output
Add GitHub Workflow

In order to run the build, we must provide a workflow. Insert the workflow in the directory required by GitHub, then run the build on ubuntu-latest with the following steps:

  • Checkout the repo
  • Run the action from the previous step
  • Output the total memory to the build log

Additional Resources

To complete this lab, you will need a GitHub account and access to via a web browser (Chrome, Firefox, or Edge).

Once you've logged into GitHub, you will create a new repository and proceed with the objectives for this hands-on lab.
