docker container 動態修改記憶體限制

docker動態修改配置用docker update,用法：

docker update -h

flag shorthand -h has been deprecated, please use --help
usage: docker update [options] container [container...]
update configuration of one or more containers
options:
--blkio-weight uint16 block io (relative weight), between 10 and 1000, or 0 to disable (default 0)
--cpu-period int limit cpu cfs (completely fair scheduler) period
--cpu-quota int limit cpu cfs (completely fair scheduler)
quota
--cpu-rt-period int limit the cpu real-time period in microseconds
--cpu-rt-runtime int limit the cpu real-time runtime in microseconds
-c, --cpu-shares int cpu shares (relative weight)
--cpuset-cpus string cpus in
which to allow execution (0-3, 0,1)
--cpuset-mems string mems in
which to allow execution (0-3, 0,1)
--help print usage
--kernel-memory string kernel memory limit
-m, --memory string memory limit
--memory-reservation string memory soft limit
--memory-swap string swap limit equal to memory plus swap: '-1' to enable unlimited swap

docker update -m 2048m gitlab

memory limit should be smaller than already set memoryswap limit, update the memoryswap at the same time

將memory-swap 設定值為 -1，表示容器程式使用記憶體受限，而 swap 空間使用不受限制。

docker update --memory 2048m --memory-swap -1 gitlab
