Advice, skype assistance - Docker containers on Centos7: daemon does not start

My docker containers on centos 7 host do not start. When I do 'docker -d -D' the output is the following: INFO[0000] +job serveapi(unix:///var/run/[login to view URL]) INFO[0000] Listening for HTTP on unix (/var/run/[login to view URL]) DEBU[0000] Registering GET, /info DEBU[0000] Registering GET, /version DEBU[0000] Registering GET, /images/viz DEBU[0000] Registering GET, /containers/ps DEBU[0000] Registering GET, /containers/{name:.*}/top DEBU[0000] Registering GET, /containers/{name:.*}/stats DEBU[0000] Registering GET, /images/{name:.*}/json DEBU[0000] Registering GET, /_ping DEBU[0000] Registering GET, /events DEBU[0000] Registering GET, /images/json DEBU[0000] Registering GET, /images/get DEBU[0000] Registering GET, /images/{name:.*}/get DEBU[0000] Registering GET, /images/{name:.*}/history DEBU[0000] Registering GET, /containers/{name:.*}/changes DEBU[0000] Registering GET, /containers/{name:.*}/logs DEBU[0000] Registering GET, /exec/{id:.*}/json DEBU[0000] Registering GET, /images/search DEBU[0000] Registering GET, /containers/json DEBU[0000] Registering GET, /containers/{name:.*}/export DEBU[0000] Registering GET, /containers/{name:.*}/json DEBU[0000] Registering GET, /containers/{name:.*}/attach/ws DEBU[0000] Registering POST, /auth DEBU[0000] Registering POST, /exec/{name:.*}/start DEBU[0000] Registering POST, /exec/{name:.*}/resize DEBU[0000] Registering POST, /containers/{name:.*}/start DEBU[0000] Registering POST, /containers/{name:.*}/rename DEBU[0000] Registering POST, /images/create DEBU[0000] Registering POST, /images/load DEBU[0000] Registering POST, /images/{name:.*}/push DEBU[0000] Registering POST, /containers/{name:.*}/wait DEBU[0000] Registering POST, /containers/{name:.*}/attach DEBU[0000] Registering POST, /containers/{name:.*}/copy DEBU[0000] Registering POST, /containers/{name:.*}/exec DEBU[0000] Registering POST, /build DEBU[0000] Registering POST, /containers/{name:.*}/unpause DEBU[0000] Registering POST, /containers/{name:.*}/restart DEBU[0000] Registering POST, /containers/{name:.*}/kill DEBU[0000] Registering POST, /containers/{name:.*}/pause DEBU[0000] Registering POST, /containers/{name:.*}/stop DEBU[0000] Registering POST, /containers/{name:.*}/resize DEBU[0000] Registering POST, /commit DEBU[0000] Registering POST, /images/{name:.*}/tag DEBU[0000] Registering POST, /containers/create DEBU[0000] Registering DELETE, /containers/{name:.*} DEBU[0000] Registering DELETE, /images/{name:.*} DEBU[0000] Registering OPTIONS, DEBU[0000] docker group found. gid: 997 DEBU[0000] libdevmapper(6): ioctl/libdm-iface.c:1795 (4) dm version OF [16384] (*1) DEBU[0000] libdevmapper(6): ioctl/libdm-iface.c:1795 (4) dm version OF [16384] (*1) DEBU[0000] devicemapper: udev sync support: true DEBU[0000] Generated prefix: docker-253:1-259000 DEBU[0000] Checking for existence of the pool 'docker-253:1-259000-pool' DEBU[0000] libdevmapper(6): ioctl/libdm-iface.c:1795 (4) dm info docker-253:1-259000-pool OF [16384] (*1) DEBU[0000] libdevmapper(6): ioctl/libdm-iface.c:1795 (4) dm status docker-253:1-259000-pool OF [16384] (*1) FATA[0000] EOF
