docker 安装
容器常用操作
查找镜像
docker search xxx
下载镜像
docker pull xxx:TAG
// TAG表示版本，不写默认最新版latest
查找镜像
docker images
删除镜像
docker rmi -f 镜像ID或镜像名(有版本号需要带版本号)
# 删除指定本地镜像
# -f 强制删除
# ID可以不用填写完
删除元信息
docker inspect 镜像ID或镜像名(有版本号带版本号)
# 获取镜像的元信息,详情信息
容器常用操作
运行
docker run --name 容器名 -i -t -p 主机端口:容器端口 -d -v 主机目录:容器目录:ro 镜像ID或镜像名:TAG
# --name 指定容器名, 不指定自动命名
# -i 以交互模式运行容器
# -t 分配一个伪终端(命令行), 通常-it组合使用
# -p 指定端口 主机端口映射到容器端口
# -d 后台运行容器
# -v 指定挂载主机到容器目录, 默认为rw读写模式, ro表示只读
# --rm t
容器列表
docker ps -a -q
# docker ps 查看正在运行的容器
# -a 查看使用容器(运行中、未运行)
# -q 只查看容器ID
启动容器
docker start 容器ID或容器名
停止容器
docker stop 容器ID或容器名
删除容器
docker rm -f 容器ID或容器名
# -f 强制删除
以交互模式执行容器内
docker exec -it 容器ID或容器名 /bin/bash
# 进入正在运行的容器并且开启交互模式终端
# /bin/bash 固有写法, 作用是因为docker后台必须运行一个进程，否则容器就会退出，在这里表示启动容器后启动
bash
# 也可以用docker exec在运行中的容器执行命令
拷贝文件
docker cp 主机文件路径 容器ID或容器名:容器路径 #主机中文件拷贝到容器中
docker cp 容器ID或容器名:容器路径 主机文件路径 #容器中文件拷贝到主机中
删除停掉的容器
docker system prune -f
