can't make forever to stay up forever

glensc commented 5 years ago

can't figure out how to make forever not to stop. I really need my application to be up forever, not stopped even if it dies immediately.

ok, value 1 seems to do the thing, but the warning is still printed. what the meh?

$ cat forever.json
{
    "minUptime": 1,
    "spinSleepTime": 1,
    "script": "lib/server.js"
}
$ docker-compose logs | head

crontab -e

@reboot /usr/bin/forever start --minUptime 5000 --spinSleepTime 2000 --sourceDir /root/source/kea_dhcp/kea-anterius ./bin/www > /dev/null 2>&1

I wanted --minUptime 0, but that disabled the feature, so I used 1
