cat /usr/lib/systemd/system/podman-coaster-celery-agent.service [Unit] Description=Celery Service via podman After=network.target

[Service] Type=forking User=root Group=root EnvironmentFile=-/etc/sysconfig/celeryd.sysconfig Environment=POD_IMG=hub.easystack.cn/escl-switch/es8 Environment=POD_OPTS="--privileged
--network=host
--pid=host
--volume /proc:/proc
--volume /var/lib/celery:/var/lib/celery
--volume /var/log/celery:/var/log/celery"

Note the -f: don't fail if there is no PID file

ExecStartPre=/bin/rm -f /var/lib/celery/${CELERYD_NODES}.pid ExecStartPre=mkdir -p /var/lib/celery /var/log/celery ExecStart=podman run $POD_OPTS $POD_IMG sh -c '${CELERY_BIN} multi start ${CELERYD_NODES}
-A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} -n celery
--logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}' ExecStop=podman run $POD_OPTS $POD_IMG /bin/sh -c '${CELERY_BIN} multi stopwait ${CELERYD_NODES}

--logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'

questions: Why is there no error when entering the container to start ExecStart, but a rough error is reported about 'conmon c82ee1934e559bd5868f : stdio_input read failed Resource ' when starting the podman-coaster-celery-agent.service?
