描述
顯示容器資源使用統(tǒng)計信息的實時流
使用
docker stats [OPTIONS] [CONTAINER...]
備選方案
名字，簡寫 | 默認 | 描述 |
|---|---|---|
--all, -a | 假 | 顯示所有容器（默認顯示正在運行） |
--format | 使用Go模板打印出圖像 | |
--no-stream | 假 | 禁用流式統(tǒng)計信息并僅提取第一個結(jié)果 |
父命令
命令 | 描述 |
|---|---|
docker | Docker CLI的基本命令。 |
擴展描述
docker stats命令返回一個用于運行容器的實時數(shù)據(jù)流。要將數(shù)據(jù)限制到一個或多個特定容器，請指定由空格分隔的容器名稱或ID列表。您可以指定已停止的容器，但已停止的容器不會返回任何數(shù)據(jù)。
如果您想了解有關(guān)容器資源使用情況的更多詳細信息，請使用/containers/(id)/statsAPI端點。
實例
docker stats針對Linux守護進程運行所有正在運行的容器。
$ docker stats CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O 1285939c1fd3 0.07% 796 KiB / 64 MiB 1.21% 788 B / 648 B 3.568 MB / 512 KB 9c76f7834ae2 0.07% 2.746 MiB / 64 MiB 4.29% 1.266 KB / 648 B 12.4 MB / 0 B d1ea048f04e4 0.03% 4.583 MiB / 64 MiB 6.30% 2.854 KB / 648 B 27.7 MB / 0 B
docker stats通過名稱和id在Linux守護進程上運行多個容器。
$ docker stats fervent_panini 5acfcb1b4fd1 CONTAINER CPU % MEM USAGE/LIMIT MEM % NET I/O 5acfcb1b4fd1 0.00% 115.2 MiB/1.045 GiB 11.03% 1.422 kB/648 B fervent_panini 0.02% 11.08 MiB/1.045 GiB 1.06% 648 B/648 B
docker stats在所有（運行和停止）容器上運行自定義格式。
$ docker stats --all --format "table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}"CONTAINER ID NAME CPU % MEM USAGE / LIMIT

docker stats針對Windows守護進程運行所有正在運行的容器。

格式化
格式化選項（--format）可以使用Go模板打印容器輸出。
Go模板的有效占位符列在下面：
占位符 | 描述 |
|---|---|
.Container | 容器名稱或ID（用戶輸入） |
.Name | 容器名稱 |
.ID | 容器ID |
.CPUPerc | CPU百分比 |
.MemUsage | 內(nèi)存使用情況 |
.NetIO | 網(wǎng)絡(luò)IO |
.BlockIO | 塊IO |
.MemPerc | 內(nèi)存百分比（Windows上不可用） |
.PIDs | PID數(shù)量（在Windows上不可用） |
使用該--format選項時，stats命令可以完全按照模板聲明輸出數(shù)據(jù)，或者在使用table指令時也包含列標題。
以下示例使用不帶標題的模板，并輸出由冒號分隔的所有圖像Container和CPUPerc條目：
$ docker stats --format "{{.Container}}: {{.CPUPerc}}"09d3bb5b1604: 6.61%9db7aa4d986d: 9.19%3f214c61ad1d: 0.00%若要以表格格式列出所有容器的統(tǒng)計數(shù)據(jù)及其名稱、CPU百分比和內(nèi)存使用情況，請使用：
$ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"CONTAINER CPU % PRIV WORKING SET
