|`spec.requiredAvailableStorage`| The minimum disk space for the pipeline’s build volume in`Gi`. <br> When defined, Codefresh assigns either a cached disk with sufficient disk space or a new empty disk at the start of the build. <br>When empty, only the space not allocated for caching is available for the build volume. <br>See[Set minimum disk space for a pipeline build]({{site.baseurl}}/docs/pipelines/pipelines/#set-minimum-disk-space-for-a-pipeline-build).| string| Optional|

|`spec.lowMemoryWarningThreshold`| The memory-usage threshold for the pipeline's build exceeding which to display banner alerts. Useful to get timely warnings and prevent build failures. <br>Can be one of the following:{::nomarkdown}<ul><li><b>WARNING</b>: Displays a banner when memory usage exceeds 70% of the available memory. </li><li><b>CRITICAL</b>: Displays a banner when memory usage exceeds 90% of the available memory. </li><li><b>REACHED_LIMIT</b>: Displays a banner when memory usage exceeds 100% of the available memory. Setting this threshold means that the pipeline build has already failed when the banner is displayed.</li></ul>{:/}See also[Set memory usage threshold for pipeline build]({{site.baseurl}}/docs/pipelines/pipelines/#set-memory-usage-threshold-for-pipeline-build).| string| Optional|

|`spec.packId`| Required for SaaS environments. Optional for hybrid environments.<br>The package identifier based on the resource size.
