Dockerfile 及其常见指令介绍

Dockerfile 其实一个文本文件，其中包含了若干个符合 Docker 解析规范的指令，指令描述了构建镜像的步骤或者一些细节。

Nginx 小例子

首先，我们新建一个简单的 Dockerfile,文件名就叫做Dockerfile，其内容如下:

?

1 2	FROM nginx RUN echo '<h1>SpringCloud-Docker</h1>' > /usr/share/nginx/html/index.html

上面的 Dockerfile 基于 nginx 镜像修改了 index.html 首页，首页显示SpringCloud-Docker内容。

我们可以通过 Docker 来构建此镜像并运行：

tom@ubuntu:~/Desktop/3/docker1$ sudo docker build -t nginx-demo .
Sending build context to Docker daemon 2.048kB
Step 1/2 : FROM nginx

随后访问http://localhost:8080得到如下响应：

或者控制台执行如下指令：

curl localhost:8080
 响应如下：

<h1>SpringCloud-Docker</h1>常见指令

上面的 Dockerfile 提到了 FROM、RUN 指令。事实上，Dockerfile 有十多个指令，一般格式是：指令名称 参数。   FROM 指定基础镜像：FROM <image>:<tag> 比如基于 Java JDK 环境的镜像：openjdk:8-jre-alpine:latest   ADD 复制文件：ADD <src> <dest> 从src目录复制文件到容器的dest目录,其中 src 可以是 Dockerfile 所在目录的相对路径，也可以是一个 URL，还可以是一个压缩包。   COPY 复制文件：COPY <src> <dest> COPY 和 ADD 指令类似，COPY 不支持 URL 的压缩包。   ENTRYPOINT 入口点：ENTRYPOINT command param1 param2

　　

指定 Docker 容器启动时执行的命令。

更多指令可以参考官方文档，这里不一一讲解。接下来开始对我们前面的 Eureka Server 微服务进行改造，使其运行在 Docker 容器中。

 No plugin found for prefix 'dockerfile' in the current project and in the plugin groups [org.apache

 

错误原因：
插件不在maven配置文件settings.xml中pluginGroups的白名单里面

解决方法：
修改maven的settings.xml配置文件，在<pluginGroups>节点中添加
