SYNOPSIS

runc update [command options] <container-id>

 

DESCRIPTION

The data can be read from a file or the standard input, the accepted format is as follow (unchanged values can be omitted):

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

Note: if data is to be read from a file or the standard input, all other options are ignored.

 

OPTIONS

--memory value               Memory limit (in bytes)
--memory-reservation value   Memory reservation or soft_limit (in bytes)
--memory-swap value          Total memory usage (memory + swap); set '-1' to enable unlimited swap
--pids-limit value           Maximum number of pids allowed in the container (default: 0)
