NAME


docker-update - Update resource configs of one or more containers

SYNOPSIS


docker update [--blkio-weight[=[BLKIO-WEIGHT]]] [--cpu-shares[=0]] [--cpu-period[=0]]
[--cpu-quota[=0]] [--cpuset-cpus[=CPUSET-CPUS]] [--cpuset-mems[=CPUSET-MEMS]] [--help]
[--kernel-memory[=KERNEL-MEMORY]] [-m|--memory[=MEMORY]]
[--memory-reservation[=MEMORY-RESERVATION]] [--memory-swap[=MEMORY-SWAP]] CONTAINER
[CONTAINER...]

DESCRIPTION


The docker update command dynamically updates container resources. Use this command to
prevent containers from consuming too many resources from their Docker host. With a
single command, you can place limits on a single container or on many. To specify more
than one container, provide space-separated list of container names or IDs.

With the exception of the --kernel-memory value, you can specify these options on a
running or a stopped container. You can only update --kernel-memory on a stopped
container. When you run docker update on stopped container, the next time you restart it,
the container uses those values.

OPTIONS


--blkio-weight=0
Block IO weight (relative weight) accepts a weight value between 10 and 1000.

--cpu-shares=0
CPU shares (relative weight)

--cpu-period=0
Limit the CPU CFS (Completely Fair Scheduler) period

--cpu-quota=0
Limit the CPU CFS (Completely Fair Scheduler) quota

--cpuset-cpus=""
CPUs in which to allow execution (0-3, 0,1)

--cpuset-mems=""
Memory nodes(MEMs) in which to allow execution (0-3, 0,1). Only effective on NUMA
systems.

--help
Print usage statement

--kernel-memory=""
Kernel memory limit (format: <number>[<unit>], where unit = b, k, m or g)

Note that you can not update kernel memory to a running container, it can only be updated
to a stopped container, and affect after it's started.

-m, --memory=""
Memory limit (format: <number><optional unit>, where unit = b, k, m or g)

--memory-reservation=""
Memory soft limit (format: <number>[<unit>], where unit = b, k, m or g)

--memory-swap=""
Total memory limit (memory + swap)

EXAMPLES


The following sections illustrate ways to use this command.

Update a container with cpu-shares=512
To limit a container's cpu-shares to 512, first identify the container name or ID. You can
use docker ps to find these values. You can also use the ID returned from the docker run
command. Then, do the following:

$ docker update --cpu-shares 512 abebf7571666

Update a container with cpu-shares and memory
To update multiple resource configurations for multiple containers:

$ docker update --cpu-shares 512 -m 300M abebf7571666 hopeful_morse
