spring boot与docker结合

spring boot可以直接将程序打包成image

新建docker registry

在180.xxx.xx.147服务器

在/etc/docker/daemon.json
添加"insecure-registries":["180.xx.xx.147:5000"] 

本地的docker也要设置

"insecure-registries":["180.xx.xx.147:5000"] 

好像因为https原因.

启动

docker run -d -p 5000:5000 --name registry registry:2

私有化docker仓库建立成功

具体可以查官方示例

新建Dockerfile文件

FROM java:openjdk-8-jre-alpine
VOLUME /tmp
ARG JAR_FILE
ADD ${JAR_FILE} app.jar

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Duser.timezone=GMT+08","-jar","/app.jar"]

其中docker.image.prefix 中”180.xxx.xx.147:5000”为私有化docker仓库地址

执行命令

mvn clean package -DskipTests

会发现先在本地生成180.xxx.xx.147:5000/test:1.0 镜像,再提交到私有仓库

换个服务器,从远程仓库拉取镜像

docker pull 180.xxx.xx.xxx:5000/test:1.0
