项目容器化
- Dockerfile
# 指定基础镜像，在此基础上制作自己的镜像
FROM openjdk:8-jre-alpine
# 声明维护者信息
MAINTAINER liuming216448
# 环境变量
Env APP_NAME spring-boot-sample
Env APP_VERSION 1.0.0-SNAPSHOT
# 创建目录
RUN mkdir -p /opt/app/${APP_NAME}
RUN mkdir -p /opt/logs/${APP_NAME}
# 将项目中已经打包好的jart包添加到镜像中
ADD target/spring-boot-sample-*.jar /opt/app/spring-boot-sample/app.jar
# 镜像的启动入口
ENTRYPOINT ["java","-jar","/opt/app/spring-boot-sample/app.jar"]
- 制作镜像
- mvn打jar包
在项目的根目录下执行mvn clean package，会在项目根目录下的target目录下生成spring-boot-sample-1.0.0-SNAPSHOT.jar - 制作镜像
在项目的根目录下执行docker build -t spring-boot-sample:1.0.1 .，开始制作镜像 ，过程如下：
- mvn打jar包
