docker rmi删除镜像

删除指定的容器
docker rmi -f image_id# 删除所有的镜像
docker rmi -f $(docker images -aq)

docker image 打包镜像

Docker 把应用程序及其依赖，打包在 image 文件里面。只有通过这个文件，才能生成 Docker 容器。image 文件可以看作是容器的模板。Docker 根据 image 文件生成容器的实例。同一个 image 文件，可以生成多个同时运行的容器实例。

image 是二进制文件。实际开发中，一个 image 文件往往通过继承另一个 image 文件，加上一些个性化设置而生成。举例来说，你可以在 Ubuntu 的 image 基础上，往里面加入 Apache 服务器，形成你的 image。

# 列出本机的所有 image 文件。
$ docker image ls# 删除 image 文件
$ docker image rm [imageName]

image 文件是通用的，一台机器的 image 文件拷贝到另一台机器，照样可以使用。一般来说，为了节省时间，我们应该尽量使用别人制作好的 image 文件，而不是自己制作。即使要定制，也应该基于别人的 image 文件进行加工，而不是从零开始制作。

为了方便共享，image 文件制作完成后，可以上传到网上的仓库。Docker 的官方仓库 Docker Hub 是最重要、最常用的 image 仓库。此外，出售自己制作的 image 文件也是可以的。

2 容器命令

docker run 启动镜像

docker run [] image# 参数说明
--name="Name" 容器名字，，同一个镜像可以由多个不同的容器。
-d 后台方式运行
-it 使用交互方式运行。金融容器查看内容
-p  指定容器端口-p 主机端口:容器端口-p 容器端口容器端口puu-p ip:主机端口:容器端口
-P  随机指定端口exit
退出容器。如果交互形式运行，退出后容器就会终止。

docker ps查看容器

• 查看正在运行的容器

docker ps-a 所有运行的容器，包括停止的容器。历史运行过的容器
-n=? 显示最近创建的容器
-q 只显示容器的编号。➜  ~ docker ps -a
CONTAINER ID   IMAGE                                                                    COMMAND                  CREATED             STATUS                         PORTS                    NAMES

退出容器

exit 容器停止退出
ctrl +p +q 容器不停止退出[root@192 ~]# docker run -it centos /bin/bash
[root@bfcea13c40cd /]# [root@192 ~]# docker ps ##注意这里会自动给个命令，删掉

docker rm删除容器

• 删除容器

docker rm container_id 删除指定的容器，不能删除正在运行的容器。
-f 可以删除正在运行的容器
-f $(docker ps -aq) 删除所有的容器。包括没在运行的容器
docker -aq |xargs docker rm 也能删除容器

启动、停止容器

docker start container_id 启动容器
docker restart container_id 重启容器
docker stop container_id 停止当前正在运行容器
docker kill container_id 强制停止当前容器

3 其他命令

后台启动容器

docker run -d centos
* docker run -d 后台运行，但是镜像停止了。后台运行，就必须有一个前台进程，docker发现没有提供服务或者没有程序应用，会自动停止。

实例：nginx容器

1. 搜索镜像search
2. 下载镜像pull
3. 创建运行run -d 后台运行–name 名称-p port端口映射
4. 查看运行ps /curl
5. 进入容器exec /attach

端口映射的原理

run --rm stop后删除
run -e 添加启动参数和启动环境参数

实例：es+kibana

• 两个容器可以通过端口映射和内网ip访问彼此的服务。
