[root@izr86 ~]#
创建容器：
docker create nginx(容器的名称)
此时创建的容器是停止状态的，没有运行的
[root@izr86 ~]# docker create nginx

删除容器
容器删除之前，要停止运行
首先要查看要删除的容器是否在运行
docker ps 查看当前运行的容器
[root@izr86 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
查看了当前的容器之后，我们删除一个容器
256192dc46e4 hello-world "/hello" 2 days ago Exited (0) 2 days ago great_gould
[root@izr86 ~]# docker rm 256192dc46e4
256192dc46e4
可以根据容器的id删除一个容器，或者是根据名称删除一个id
docker 启动容器
docker start 容器名称/id
[root@izr86 ~]# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
39ab25ad95fa nginx "nginx -g 'daemon of…" 15 minutes ago Exited (0) About a minute ago nginx1
[root@izr86 ~]# docker start nginx1
nginx1
docker 关闭运行的容器
docker stop 容器名称/id
[root@izr86 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
39ab25ad95fa nginx "nginx -g 'daemon of…" 10 minutes ago Up 10 minutes 80/tcp, 0.0.0.0:8090->90/tcp nginx1
[root@izr86 ~]# docker stop 39ab25ad95fa
39ab25ad95fadocker 运行一个容器
docker run -d -p 8090:90
-d 表示容器在后台运行，-p 表示将容器的 80 端口映射到宿主机的 8080 端口，
[root@izr86 ~]# docker run -d -p 8090:90 nginx

[root@izr86 ~]# 但是我们现在是无法外网8090的，或者说访问不通
因为我们绑定的是docker的90端口，我们必须绑定docker的80端口才能进行通过外网访问
[root@izr86o15kikb3az ~]# docker run -d -p 8090:80 nginx

上面介绍的docker的基础，一些基本的应用
希望对你有所帮助
