runc-update - update running container resource constraints

       The update command change the resource constraints of a running container instance.

       The  resources  can  be set using options, or, if -r is used, parsed from JSON provided as a file or from
       stdin.

       In case -r is used, the JSON format is like this:

       {
            "memory": {
                 "limit": 0,
                      "reservation": 0,
                      "swap": 0,
                      "kernel": 0,
                      "kernelTCP": 0
            },
                 "cpu": {
                      "shares": 0,
                      "quota": 0,
                      "burst": 0,
                      "period": 0,
                      "realtimeRuntime": 0,
                      "realtimePeriod": 0,
                      "cpus": "",
                      "mems": ""
                 },
                 "blockIO": {
                      "blkioWeight": 0
                 }
       }

runc-update - update running container resource constraints

--resources|-rresources.json
              Read the new resource limits from resources.json. Use - to read from  stdin.  If  this  option  is
              used, all other options are ignored.

       --blkio-weightweight
              Set a new io weight.

       --cpu-periodnum
              Set CPU CFS period to be used for hardcapping (in microseconds)

       --cpu-quotanum
              Set CPU usage limit within a given period (in microseconds).

       --cpu-burstnum
              Set CPU burst limit within a given period (in microseconds).

       --cpu-rt-periodnum
              Set CPU realtime period to be used for hardcapping (in microseconds).

       --cpu-rt-runtimenum
              Set CPU realtime hardcap limit (in usecs). Allowed cpu time in a given period.

       --cpu-sharenum
              Set CPU shares (relative weight vs. other containers).

       --cpuset-cpuslist
              Set CPU(s) to use. The list can contain commas and ranges. For example: 0-3,7.

       --cpuset-memslist
              Set memory node(s) to use. The list format is the same as for --cpuset-cpus.

       --memorynum
              Set memory limit to num bytes.

       --memory-reservationnum
              Set memory reservation, or soft limit, to num bytes.

       --memory-swapnum
              Set total memory + swap usage to num bytes. Use -1 to unset the limit (i.e. use unlimited swap).

       --pids-limitnum
              Set the maximum number of processes allowed in the container.

       --l3-cache-schemavalue
              Set the value for Intel RDT/CAT L3 cache schema.

       --mem-bw-schemavalue
              Set the Intel RDT/MBA memory bandwidth schema.
