win10 下springcloud打包docker镜像部署。

1：建一个最简单的springcloud应用。

2:在根目录下新建dockerfile，文件如下：

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

3：pom.xml中填加依赖：

4：在idea下terminal下执行打包镜像指令：mvn install dockerfile:build 。成功后会返回镜像id,也可以在cmd中用docker -images指令看新打包的镜像id。我电脑上已经安装了docker for window.

5:运行打包好的springcloud项目。指令：docker run --name Test-v1.2 -d -p 9001:8080 3750bb60f76c

（Test-v1.2--为运行镜像时取的一个名称，-d 在后台运行， -p 端口映射，3750bb60f76c 镜像id）

 

6:在本机访问docker内的应用：http://localhost:9001/user/find

最基本的应用部署ok了，后面可能尝试下.net core webapi 部署到docker，本地docker镜像上传到腾讯云运行，本地docker镜像上传docker hub(https://www.cnblogs.com/longdb/p/10500891.html)。

最后感谢 永恒||承诺 兄弟的远程帮忙。
