Angular Service Build Failed because of Jenkins Hardware Limits

Description

We are adding angular service deployment support to Jazz Platform. For this process, Jazz platform have to take angular build to generate html,css & js files & deploy it to cloud. But before that Jazz have to install/update library packages from node package manager(NPM). This npm install or npm update requires sufficient cpu units and memory to properly build cache and pull packages and install it to the service. This is getting failed sometimes because of the Jenkins container hardware limits.

Observations

1. During jenkins build website buildpack failed. Reason: npm ERR! nospc ENOSPC: no space left on device
2. In AWS, the CPUUtilization of the service ecs_cluster_jenkins hits 100% during npm process.

Suggestions

1. Increase the value of Task CPU which is part of the Jenkins Task Definition (ecs_task_definition_jenkins).
2. Clear possible temp files & workspace directories of Jenkins at the initial stage of the Jenkins build process.
3. reduce disk free space threshold & temp free space threshold in the Jenkins master node configuration.

@suryajak @deepusundar Please have a look.

@francis-ve Thanks for reporting the issue. Please find the Limitations section in Jazz-Installer https://github.com/tmobile/jazz-installer/wiki#limitations

As suggested, we are already working on decreasing the threshold limits. Also can increase the CPU limit based on the requirement https://github.com/tmobile/jazz-installer/blob/668020d3e44b0d128b5ceaedc1eaa51e1e14ce70/installscripts/jazz-terraform-unix-noinstances/variables.tf#L128.

At this time, we are not clearing any work space related files for the core services through code. But can manually delete those files/folders through Jenkins script console.

@rajeevr2715 Thank you for the information you shared.
