Need to select the target for appctl commands:

[root@compute1 ~]# docker exec openvswitch_vswitchd ls /var/run/openvswitch/
db.sock
ovs-vswitchd.5.ctl
ovsdb-server.12.ctl
ovsdb-server.14.ctl
[root@compute1 ~]# docker exec openvswitch_vswitchd ovs-appctl -t /var/run/openvswitch/ovsdb-server.14.ctl memory/show
