shell脚本发布docker springboot项目示例

docker、git、Maven、jdk8安装略过。
使git pull或者git push不需要输入密码操作方法

约定：

路径：/opt/springbootdemo，

项目：springbootdemo，

打包：springbootdemo.jar，

docker容器名字：springbootdemo

Dockerfile

内存不够自行调整："-Xmx6144m","-Xms6144m"

bash 复制代码

FROM openjdk:8
MAINTAINER "hsj<[email protected]>"
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
COPY ./target/springbootdemo.jar ./springbootdemo.jar
EXPOSE 55530
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Dfile.encoding=utf-8","-jar","-Xmx6144m","-Xms6144m","/springbootdemo.jar","--spring.profiles.active=prod"]

pro_build.sh

注意：#!/bin/bash -ilex ，如果jenkins远程ssh登录执行sh脚本，并且jekins安装在docker容器里面 ，这句代码很有必要。

bash 复制代码

#!/bin/bash -ilex
#环境变量
who am i
set -e
# ./nginx -s reload
#当前springboot目录
cd /opt/springbootdemo

echo "拉取gitlib最新代码..."
git status && git pull

#if判断其实是多余的，set -e 当$? 不等于0时候已经退出了
if [[ $? -ne 0 ]]
then
  echo "拉取gitlib最新代码失败，准备退出"
  exit 1

echo "拉取gitlib最新代码成功"

echo "准备构建jar包..."
mvn clean package

echo "正在扫描docker容器启动状态..."
set +e
start_time=$(date -d "today" +%s);
#springbootdemo: Started Application
while true; do docker logs springbootdemo 2>&1 | grep "Started Application" > /dev/null;
