Docker常用命令介绍

1、docker常用命令

命令 作用
docker search 查询镜像
docker pull 从网上拉取镜像
docker create 创建容器
docker ps 查看容器进程
docker start 启动容器进程
docker stop 终止容器进程
docker logs 查看日志
docker images 查看docker中的镜像
docker rm 删除镜像
docker rmi 删除docker容器
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

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
