- 5.4 根据容器的id或name进入容器并修改容器里面的内容
- 六、通过commit将容器变为新的镜像
- 七、通过Dockerfile创建镜像
- 八、docker镜像和tar文件之间的转换
- 8.1 docker save
- 8.2 docker load
- 九、将宿主机上文件路径挂载到容器内部的某个路径
- 十、宿主机上文件和容器内部文件互相拷贝
一、说明
如图所示，docker的核心就是docker镜像，我们可以通过docker命令来实现各个单元的互相转化。
下面我们可以通过镜像文件 “nginx” 来感受一下 Docker。
二、docker服务端信息
| 服务器ip | 主机名 | 系统版本 |
|---|---|---|
| 192.168.2.201 | myhost | Centos7.2 |
docker安装教程请参考前面的文章：Centos7.2上安装Docker
三、查看docker服务启动状态
[root@myhost ~]# /bin/systemctl status docker.service

Hint: Some lines were ellipsized, use -l to show in full.四、从镜像仓库拉取镜像文件到本地
命令：docker pull image_name
说明：如果镜像名后面不加上版本信息，则默认拉取此镜像的最新版本。
例如： docker pull nginx == docker pull nginx:latest
4.1 拉取nginx镜像文件最新版本
[root@myhost ~]# docker pull nginx:latest
Trying to pull repository docker.io/library/nginx ...

4.2 拉取nginx镜像文件1.16.1版本
[root@myhost ~]# docker pull nginx:1.16.1

4.3 根据镜像文件的id或name删除镜像
命令： docker rmi image_name/image_id
说明：一个镜像如果关联某个或几个容器，是不能直接被删除的，必须先停止并删除所有相关容器之后才能够删除此镜像。如果不先停止并删除所有相关容器，也可以使用 docker rmi image_name/image_id -f 命令来强制删除此镜像。
[root@myhost ~]# docker rmi 62d49f9bab67

4.4 查看系统存在的镜像文件
命令： docker images 查看现在存在的镜像文件。
参数： --no-trunc 不截断输出，显示完整的镜像信息（比如：会显示镜像文件的完整ID）。

五、通过镜像文件来创建一个新的容器并运行一个命令
命令：docker run image_name/image_id 通过镜像文件来创建一个新的容器并运行一个命令。
’常用参数：
- -d 后台运行容器，并返回容器ID；
- -p 指定端口映射，格式为：主机(宿主)端口:容器端口
- -i 以交互模式运行容器，通常与 -t 同时使用；
- -e username=“root”: 设置运行容器时的环境变量；
- – name=“mynginx”: 为容器指定一个名称；
5.1 使用nginx:latest 镜像以后台模式启动一个容器，并将容器端口映射到宿主机80端口
[root@myhost ~]# docker run -d -p 80:80 nginx:1.16.1

七、通过Dockerfile创建镜像
命令： docker build -t new_image_name
参数：–tag, -t: 镜像的名字及标签，通常 name:tag 或者 name 格式；可以在一次构建中为一个镜像设置多个标签。
[root@myhost ~]# pwd
/root
[root@myhost ~]# vi Dockerfile
[root@myhost ~]# cat Dockerfile
from nginx:1.16.1
add ./index.html /usr/share/nginx/html/

十、宿主机上文件和容器内部文件互相拷贝
从宿主机复制到容器中： docker cp host_path container_id:container_path
从容器复制到宿主机中： docker cp container_id:container_path host_path
注意： container_id 必须是容器的完整id，查看容器长id： docker ps --no trunc
docker容器内无法删除文件
