I have just tried using dumb-init
now i am getting following three processes
`15-096-Goyal:exanova-templates gaurav.goyal$ docker exec -it d053f9d31436
ps -ef
PID USER TIME COMMAND
1 root 0:00 dumb-init /opt/nifi/bin/nifi.sh run
7 root 0:00 {nifi.sh} /bin/sh /opt/nifi/bin/nifi.sh run
19 root 0:00 {nifi.sh} /bin/sh /opt/nifi/bin/nifi.sh run`
executing docker stop gave "ExitCode": 143.
is it correct way to use dumb-init?
`def run():
logger.info('Starting Nifi.')
os.execl('/usr/bin/dumb-init', 'dumb-init', '/opt/nifi/bin/nifi.sh',
'run')`
