以上就是所有的docker的命令,你也可以使用如下指令来查看docker中更加详细的配置项
docker COMMAND --help
下面介绍一下常用的命令吧:
- docker ps 显示正在运行的容器
- docker ps -a 显示所有的容器,包括暂停的
- docker images 显示所有镜像
- docker rm 容器ID 删除某个容器
- docker rmi 镜像ID 删除某个镜像
注意 删除操作的时候有一个稍微可以让你简单一点点的小技巧
这时候你想要删除这个容器的话,你可以直接输入
docker rm d
就可以了,因为因为开头为d的只有那么一个,所以docker可以找到,所有操作都可以这样做,只要你给的标识唯一的话,docker就可以进行操作
- docker build -t tag . 构建镜像,tag用于标示这个镜像,后面的 . 表示Dockerfile在当前目录,如果Dockerfile不在当前目录需要将Dockerfile的路径完整写上去
- docker run -p 80:80 -d tag 运行这个容器,-p表示本地80端口映射到容器80端口以后面的端口运行, -d表示后台运行
- docker stop/start/restart tag 表示停止,开启,重启容器
- docker exec -it containerID /bin/bash 进入容器内部
- docker logs -f container-name 显示该容器所有命令
- docker logs -n 10 container-name 显示最近10行日志
