docker exec	交互式进入docker容器中
docker run	拉取镜像，创建容器、启动容器
dcoker kill	强行终止docker进程

2、例子

2.1、查询、拉取容器

# docker images 			---列出本地镜像
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

# docker search nginx 		  ---- 查询nginx镜像

2.2、创建并且启动容器

# docker ps -a				---查询所有进程
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
8f7f5e453029        nginx               "/docker-entrypoint.…"   13 seconds ago      Created                                 condescending_einstein
# docker start 8f7f5e453029				---启动nginx进程
8f7f5e453029
# docker ps					---查看启动进程
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
8f7f5e453029        nginx               "/docker-entrypoint.…"   49 seconds ago      Up 9 seconds        80/tcp              condescending_einstein
[root@docker ~]# 

最简单的拉取、创建、启动

[root@docker ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@docker ~]# docker run -d -it nginx

3、终止容器进程

# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
8f7f5e453029        nginx               "/docker-entrypoint.…"   5 minutes ago       Up 15 seconds       80/tcp              condescending_einstein
# docker stop 8f7f5e453029				---停止nginx容器进程
8f7f5e453029
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
# docker restart 8f7f5e453029			---重启
8f7f5e453029
# docker kill 8f7f5e453029				---强行终止
8f7f5e453029
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
#

4、进入容器

# docker exec -it 8f7f5e453029 /bin/bash
root@8f7f5e453029:/# ls
bin   dev		   docker-entrypoint.sh  home  lib64  mnt  proc  run   srv  tmp  var
boot  docker-entrypoint.d  etc			 lib   media  opt  root  sbin  sys  usr
root@8f7f5e453029:/# exit

5、删除容器和镜像

1、关闭所有该容器进程

2、删除容器

4、删除镜像

# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
8f7f5e453029        nginx               "/docker-entrypoint.…"   10 minutes ago      Up About a minute   80/tcp              condescending_einstein
# docker stop 8f7f5e453029
8f7f5e453029
# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
