Jenkins 自动打包java项目镜像部署到服务器

前置操作参考

配置好git地址、账号凭证、远程执行token、打通jinkens服务器到目标服务器免密传输等

Java Dockerfile

bash 复制代码

# 使用 JDK 8 精简版镜像
FROM frolvlad/alpine-java:jdk8-slim

# 作者信息
LABEL maintainer="flgb"

# 设置环境变量
ENV SPRING_OUTPUT_ANSI_ENABLED=ALWAYS \
    JAVA_OPTS="-Xms2048m -Xmx2048m -Dspring.profiles.active=uat"

# 复制 JAR 包到容器内
COPY xx-admin.jar /ky-admin.jar

# 运行应用
ENTRYPOINT exec java $JAVA_OPTS -jar /ky-admin.jar

# 显示暴露端口
EXPOSE 6088

Shell脚本

bash 复制代码

# 到工作空间目录
cd ${codeRootDir}
