Docker 镜像及容器命令
作者：互联网
十年河东，十年河西，莫欺少年穷
学无止境，精益求精
授人以鱼不如授人以渔，先列出官方命令文档
docker命令文档地址：https://docs.docker.com/engine/reference/commandline/images/
镜像相关指令
镜像是容器的模板，这句话是考点，记住啦
docker 镜像基本命令大致分为，查看镜像，搜索镜像，下载镜像、删除镜像
1、查看镜像
查看镜像命令/
docker images
查看镜像帮助命令
docker images --help
列出所有镜像
docker images -a
列出镜像ID
docker images -q
列出所有镜像ID
docker images -aq
2、搜索镜像
docker search mysql
搜索镜像后，会根据搜索到的镜像名称，描述，星数量等信息展示
docker search --help --查看帮助
根据条件搜索镜像【搜索星星在3000颗以上的MqSQL】
docker search mysql --filter=stars=3000
3、下载镜像 docker pull
下载MySQL镜像，没有指定版本号的情况下，会下载最新的MqSQL版本
docker pull mysql
下载指定版本的Mysql镜像
docker pull mysql:5.7
4、删除镜像 docker rmi -f
删除指定ID的镜像
docker rmi -f c20987f18b13
删除指定查询范围的镜像
docker rmi -f $(docker images -aq)
上述指令会删除所有镜像，他的条件是 docker images -aq
我的练习指令如下：
[root@localhost ~]# docker images

容器命令
在容器命令之前，先说个考点，有了镜像，我们就可以创建容器了
首先我们先下载个centos 镜像
docker pull centos
1、新建一个名字为：mycentos 的容器并运行它
docker run -it --name=mycentos centos:latest /bin/bash-i 运行容器-t 容器启动后进入该容器执行命令，加入这两个参数，容器创建就能登录进去-name 为创建的容器命名
-v 表示目录的映射关系 本地目录和docker容器目录映射起来 前面宿主机目录，后者是容器的目录，可以使用多个-v 注意：最好做目录映射，在宿主机上面修改文件，然后共享到容器中
-d 在run后面加上-d参数，则会创建一个守护进程在后台运行（这样创建后不会自动登录容器，如果只加-it聚会在创建容器后进入容器）
-p 标识端口映射，前者宿主机端口，后者是容器的映射端口，可以使用多个-p做多个端口映射
-P 随机分配端口
–dns 8.8.8.8 指定容器使用的DNS，默认和宿主机一样
–dns-search example.com 指定容器的DNS搜索的域名，默认和宿主机一致
-h “host——001” 指定容器的hostname
-e username=‘cat’ 设置环境变量
–env-file=[] 从指定文件读入环境变量
–cpuset=“0-2” or --cpuset=“0,1,2” 绑定容器到指定CPU运行
-m 设置容器使用内存大小
–net=“bridge” 指定容器的网络连接类型，支持：bridge/host/none/container四种类型
–link=[] 添加连接到另一个容器
2、退出容器且容器停止运行
exit
如果要退出容器但不想让容器停止运行，可以使用快捷键，ctrl+p+q
使用快捷键后，我们可以看到我们的容器还是在运行的，如下,docker ps
3、查看当前运行的容器
docker ps
4、查看容器
docker ps -l --查看最近一次运行的容器
docker ps -a --查看全部容器
5、查看已经关闭的容器
docker ps -f status=exited
6、停止运行的容器
docker stop 容器ID 平滑关闭 docker kill 容器ID 强制关闭
7、重启容器
docker restart 容器名称OR容器ID
8、查看容器内运行的进程
docker top 容器名 or 容器ID
9、查看容器日志
- -t 显示时间
- -f 追加查看
- –tail 看最后几条 n是几条
docker logs -t -f 容器ID（or 容器名称） docker logs -f -t db950b0be73a
docker logs -t -f --tail n 容器ID（or 容器名称）n是显示几条
10、删除容器
docker rm 容器名称 OR 容器ID 容器必须要关闭 docker rm -f 容器名称 OR 容器ID 强制删除容器（运行和未运行的）
11、删除全部正在运行的容器
docker rm -f $(docker ps -q) -q 是运行容器的容器ID
