docker基础:容器操作命令

Blog:博客园 个人

容器操作

  • docker ps:列出容器;
  • docker inspect:获取容器/镜像的元数据;
  • docker top:查看容器中运行的进程信息;
  • docker events:从服务器获取实时事件;
  • docker logs:获取容器的日志;
  • docker wait:阻塞运行直到容器停止,然后打印出它的退出代码;
  • docker export:将文件系统作为一个tar归档文件导出到STDOUT;
  • docker port:列出指定的容器的端口映射,或者查找将PRIVATE_PORT NAT到面向公众的端口;
  • docker stats:显示容器资源使用情况统计信息的实时流;

      --help            Print usage
  -s,--size            Display total file sizes if the type is container
      --type string     Return JSON for specified type

查看容器中运行的进程信息

语法如下:

docker top CONTAINER [ps OPTIONS]

获取事件

语法如下:

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 logs since timestamp
      --tail string    Number of lines to show from the end of the logs (default "all")
  -t,--timestamps     Show timestamps

阻塞运行

语法如下:

docker wait CONTAINER [CONTAINER...]

导出容器

语法如下:

docker export [OPTIONS] CONTAINER

Options:
  -o,--output string   Write to a file,instead of STDOUT

端口映射

语法如下:

docker port CONTAINER [PRIVATE_PORT[/PROTO]]

显示资源使用

语法如下:
