一.从镜像启动一个容器
1>.前台启动容器
[root@docker201.yinzhengjie.org.cn ~]# docker image ls

[root@docker201.yinzhengjie.org.cn ~]# docker run -d nginx #后台启动容器，并生成随机的容器ID和名称。
3>.创建容器时并进入容器（依赖于"-i"(保持一个标准输入)和"-t"(分配一个tty终端)两个参数）
[root@docker201.yinzhengjie.org.cn ~]# docker image ls

[root@docker201.yinzhengjie.org.cn ~]# docker run -it nginx bash #会打开一个bash并直接进入到容器，并随机生成容器ID和名称。
4>.自定义容器名称(一般在单机上会有点作用，在k8s集群中咱们很少去自定义容器名称哟~)
[root@docker201.yinzhengjie.org.cn ~]# docker image ls

5>.单次运行容器(容器退出后会自动删除,主要用于临时验证镜像内容的是否符合咱们的标准，如配置文件目录组织结构等信息)
6>.启动容器时指定DNS服务器地址及主机名等
[root@docker201.yinzhengjie.org.cn ~]# docker image ls

7>.创建容器时传递运行参数(容器需要有一个前台运行的进程才能保容器的运行，通过传递运行参数是一种方式，另外也可以在构建镜像的时候指定容器启动时在前台的运行命令)
[root@docker201.yinzhengjie.org.cn ~]# docker image ls
