Update running container resource constraints

Fields

resources: Option<PathBuf>

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

blkio_weight: Option<u64>

Set a new I/O weight

cpu_period: Option<u64>

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

cpu_quota: Option<u64>

Set CPU usage limit within a given period (in microseconds)

cpu_rt_period: Option<u64>

Set CPU realtime period to be used for hardcapping (in microseconds)

cpu_rt_runtime: Option<u64>

Set CPU realtime hardcap limit (in microseconds)

cpu_share: Option<u64>

Set CPU shares (relative weight vs. other containers)

cpuset_cpus: Option<String>

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

cpuset_mems: Option<String>

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

memory: Option<u64>

Set memory limit to num bytes.

memory_reservation: Option<u64>

Set memory reservation (or soft limit) to num bytes.

memory_swap: Option<i64>

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

pids_limit: Option<i64>

Set the maximum number of processes allowed in the container

l3_cache_schema: Option<String>

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

mem_bw_schema: Option<String>

Set the Intel RDT/MBA memory bandwidth schema.

container_id: String

Trait Implementations

impl Args for Update
