Which SLIs/SLOs are relevant for Container build performance?

When managing the performance of container builds, certain Service Level Indicators (SLIs) and Service Level Objectives (SLOs) are critical to ensure efficient operations. Here are some relevant SLIs/SLOs for container build performance:

  • Build Time: The total time taken from the start to the completion of a container build.
  • Success Rate: The percentage of successful builds compared to the total number of builds initiated.
  • Resource Utilization: The CPU and memory usage during the build process, ensuring optimal use of resources.
  • Image Size: The size of the container images produced; smaller images are often preferable as they are faster to pull and deploy.
  • Build Frequency: How often builds are triggered within a given time frame, indicating the development pace.

Example of SLI/SLO Monitoring in PHP

<?php // Example to measure build time in a container $startTime = microtime(true); // Simulating container build process sleep(5); // Simulates a 5 second build time $endTime = microtime(true); $buildTime = $endTime - $startTime; if ($buildTime <= 10) { // Setting an SLO of 10 seconds echo "Build Successful! Time taken: " . $buildTime . " seconds."; } else { echo "Build Failed! Time exceeded SLO of 10 seconds."; } ?>
