docker run命令
docker run [选项] [镜像名] [shell命令] [参数]
# 常用选项:
-i, --interactive Keep STDIN open even if not attached，通常和-t一起使用
-t, --tty 分配pseudo-TTY，通常和-i一起使用,注意对应的容器必须运行shell才支持进入
-d, --detach 后台运行，并打印容器ID
--name string 给容器命名
--h, --hostname string Container host name
--rm 退出的时候自动删除容器
-p, --publish list 指定容器端口发布映射到宿主机指定端口
-P, --publish-all 发布所有的容器端口到宿主机的随机端口
--dns list Set custom DNS servers
--entrypoint string Overwrite the default ENTRYPOINT of the image
--restart policy 设置策略，决定容器是否随宿主机重启而重启
--privileged Give extended privileges to container
-e, --env=[] 设置环境变量
--env-file=[] 从指定文件中读取环境变量设置
--cpus decimal 指定容器可用的虚拟cpu数量
-m, --memory bytes 限制容器可使用的内存最大值
创建容器并退出
注意：容器启动后,如果容器内没有前台运行的进程,将自动退出停止
# exit正常退出后容器停止
[root@ubuntu2004:~]# docker run -it --name alpine-1 alpine

创建守护式容器
守护式容器的三个特点：
- 能够长期运行
- 无需交互式会话
- 适合运行应用程序和服务
# 直接docker run 守护式进程，进程会以前台方式运行

docker cp命令
docker cp命令类似于scp命令，可以实现宿主机和容器之间的文件互传
[root@ubuntu2004:~]# docker cp --help
Usage: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH
Copy files/folders between a container and the local filesystem
Use '-' as the source to read a tar archive from stdin
and extract it to a directory destination in a container.
Use '-' as the destination to stream a tar archive of a
container source to stdout.

-a, --archive Archive mode (copy all uid/gid information)
-L, --follow-link Always follow symbol link in SRC_PATH
容器中的文件传到宿主机
