In a future release, --detach=false will become the default. $ docker service ls ID NAME MODE REPLICAS IMAGE PORTS 2ihgni3msvgx influxdb replicated 1/1 influxdb:1.3 *:8083->8083/tcp,*:8086->8086/tcp $ docker service ps influxdb ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS ur5tk4emglcu influxdb.1 influxdb:1.3 Mai-II Running Running about a minute ago ```   #### cAdvisor on swarm ```powershell $ docker service create --network logging --name cadvisor --mode global --mount source=/var/run,type=bind,target=/var/run,readonly=false --mount source=/,type=bind,target=/rootfs,readonly=true --mount source=/sys,type=bind,target=/sys,readonly=true --mount source=/var/lib/docker,type=bind,target=/var/lib/docker,readonly=true google/cadvisor:v0.23.8 -storage_driver=influxdb -storage_driver_host=influxdb:8086 -storage_driver_db=cadvisor itcf68rul93zwpybg6vhvt17e Since --detach=false was not specified, tasks will be created in the background.
