容器操作
docker ps
:列出容器;docker inspect
:獲取容器/鏡像的元數據;docker top
:查看容器中運行的進程信息;docker events
:從伺服器獲取實時事件;docker logs
:獲取容器的日誌;docker wait
:阻塞運行直到容器停止,然後列印出它的退出代碼;docker export
:將文件系統作為一個tar歸檔文件導出到STDOUT;docker port
:列出指定的容器的埠映射,或者查找將PRIVATE_PORT
NAT到面向公眾的埠;docker stats
:顯示容器資源使用情況統計信息的實時流;
列出容器
語法如下:
docker ps [OPTIONS]
Options:
-a, --all Show all containers (default shows just running)
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print containers using a Go template

-l, --latest Show the latest created container (includes all states)
--no-trunc Don't truncate output
-q, --quiet Only display numeric IDs
-s, --size Display total file sizes
獲取容器/鏡像的元數據
語法如下:
docker inspect [OPTIONS] NAME|ID [NAME|ID...]
Options:
-f, --format string Format the output using the given Go template
--help Print usage
-s, --size Display total file sizes if the type is container
--type string Return JSON for specified type
查看容器中運行的進程信息
語法如下:
docker top CONTAINER [ps OPTIONS]
獲取事件
語法如下:
docker events [OPTIONS]
Options:
-f, --filter filter Filter output based on conditions provided
--format string Format the output using the given Go template
--since string Show all events created since timestamp
--until string Stream events until this timestamp
獲取日誌
語法如下:
docker logs [OPTIONS] CONTAINER
Options:
--details Show extra details provided to logs
-f, --follow Follow log output
--since string Show logs since timestamp
--tail string Number of lines to show from the end of the logs (default "all")
-t, --timestamps Show timestamps
阻塞運行
語法如下:
docker wait CONTAINER [CONTAINER...]
導出容器
語法如下:
docker export [OPTIONS] CONTAINER
Options:
-o, --output string Write to a file, instead of STDOUT
埠映射
語法如下:
docker port CONTAINER [PRIVATE_PORT[/PROTO]]
顯示資源使用
語法如下:
docker stats [OPTIONS] [CONTAINER...]
Options:
-a, --all Show all containers (default shows just running)
--format string Pretty-print images using a Go template
--no-stream Disable streaming stats and only pull the first result
