Before this change, a process running inside every SONiC container dealt with FEATURE table 'auto_restart' field and depending on the value decided whether a container has to be killed or not. If killed service auto restart mechanism restarts the container. This change moves the logic from container to the host daemon - hostcfgd. The 'auto_restart' handling is kept in supervisor-proc-exit-listener but now it is not required for container that wants to support auto restart feature. hostcfgd refactoring - move feature handling in another class. override systemd service Restart= setting from hostcfgd. remove default systemd Restart=always. Signed-off-by: Stepan Blyshchak stepanb@nvidia.com - Why I did it Remove the need to deal with container orchestration logic from the container itself. Leave this logic to the orchestrator - host OS. - How I did it hostcfgd configures 'Restart=' value for systemd service. - How to verify it root@r-tigon-11:/home/admin# sudo config feature autorestart lldp enabled root@r-tigon-11:/home/admin# show feature status | grep lldp lldp enabled enabled root@r-tigon-11:/home/admin# docker exec -it lldp pkill -9 lldpd root@r-tigon-11:/home/admin# docker ps -a | grep lldp 65058396277c docker-lldp:latest "/usr/bin/docker-lld…" 2 days ago Exited (0) 20 seconds ago lldp root@r-tigon-11:/home/admin# docker ps -a | grep lldp 65058396277c docker-lldp:latest "/usr/bin/docker-lld…" 2 days ago Up 5 seconds lldp root@r-tigon-11:/home/admin# sudo config feature autorestart lldp disabled root@r-tigon-11:/home/admin# docker exec -it lldp pkill -9 lldpd root@r-tigon-11:/home/admin# docker ps -a | grep lldp 65058396277c docker-lldp:latest "/usr/bin/docker-lld…" 2 days ago Up 35 seconds lldp root@r-tigon-11:/home/admin# docker ps -a | grep lldp 65058396277c docker-lldp:latest "/usr/bin/docker-lld…" 2 days ago Exited (0) 3 seconds ago lldp root@r-tigon-11:/home/admin# docker ps -a | grep lldp 65058396277c docker-lldp:latest "/usr/bin/docker-lld…" 2 days ago Exited (0) 39 seconds ago lldp root@r-tigon-11:/home/admin# |
