+
+
+OPTIONS
+-------
+The following container options are available:
+
+*-n, --name='NAME'*::
+	Specify container name.
+
+*--blockio-device-weight='DEVICE WEIGHT'*::
+	Specify device specific blockio weight, see systemd.resource-control(5).
+
+*--blockio-read-bandwidth='DEVICE BYTES'*::
+	Specify device specific blockio read bandwidth, see systemd.resource-control(5).
+
+*-b, --blockio-weight='WEIGHT'*::
+	Specify general blockio weight, see systemd.resource-control(5).
+
+*--blockio-write-bandwidth='DEVICE BYTES'*::
+	Specify device specific blockio write bandwidth, see systemd.resource-control(5).
+
+*-c, --cpu-quota='QUOTA'*::
+	Specify CPU quota, see systemd.resource-control(5).
+
+*--cpu-shares='SHARES'*::
+	Specify CPU shares, see systemd.resource-control(5).
+
+*-m, --memory-limit='BYTES'*::
+	Specify memory limit, see systemd.resource-control(5).
+
+*-t, --tasks-max='NUMBER'*::
+	Specify tasks max, see systemd.resource-control(5).
+
+
+EXAMPLES
+--------
+*Set blockio weight for the example.net container:*::
+	sudo container limit -n example.net --blockio-weight 100
+
+*Set CPU quota for the example.net container:*::
+	sudo container limit -n example.net --cpu-quota 10%
+
+*Set memory limit for the example.net container to 1GB:*::
+	sudo container limit -n example.net --memory-limit 1G
+
+*Set tasks max for the example.net container to 100:*::
+	sudo container limit -n example.net --tasks-max 100
