Scripts which perform an installable binary image build for SONiC
Role in this project:
DevOps Engineer
DevOps EngineerContributions:180 reviews, 84 commits, 128 PRs in 2 years 9 months
Contributions summary:Yong primarily contributed to the automation and reliability of the SONiC build image by implementing and modifying services and container configurations. Their work involved adding auto-restart mechanisms for various services (SNMP, Router-advertiser, Platform-monitor, Teamd, DHCP-Relay, LLDP, Telemetry, Sflow, and BGP), integrating a container monitoring system (Monit), and configuring systemd to manage container restarts based on configuration settings. They also updated the Dockerfiles and service files for several components and improved the overall build image, making the system more robust and resilient to failures.
