runc update - update container resource constraints
SYNOPSIS
runc update [command options]
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
--resources value, -r value path to the file containing the resources to update or '-' to read from the standard input --blkio-weight value Specifies per cgroup weight, range is from 10 to 1000 (default: 0) --cpu-period value CPU CFS period to be used for hardcapping (in usecs). 0 to use system default --cpu-quota value CPU CFS hardcap limit (in usecs). Allowed cpu time in a given period --cpu-rt-period value CPU realtime period to be used for hardcapping (in usecs). 0 to use system default --cpu-rt-runtime value CPU realtime hardcap limit (in usecs). Allowed cpu time in a given period --cpu-share value CPU shares (relative weight vs. other containers) --cpuset-cpus value CPU(s) to use --cpuset-mems value Memory node(s) to use --kernel-memory value Kernel memory limit (in bytes) --kernel-memory-tcp value Kernel memory limit (in bytes) for tcp buffer --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
