Why I did it Part implementation of dhcp_server. HLD: sonic-net/SONiC#1282. Add dhcpservd to dhcp_server container. How I did it Add installing required pkg (psutil) in Dockerfile. Add copying required file to container in Dockerfile (kea-dhcp related and dhcpservd related) Add critical_process and supervisor config. Add support for generating kea config (only in dhcpservd.py) and updating lease table (in dhcpservd.py and lease_update.sh) How to verify it Build image with setting INCLUDE_DHCP_SERVER to y and enabled dhcp_server feature after installed image, container start as expected. Enter container and found that all processes defined in supervisor configuration running as expected. Kill processes defined in critical_processes, container exist.
