给个 S2i 模板 脚本

以下是一个简单的 S2i 模板脚本示例：

assemble 脚本：

#!/bin/bash

echo "Building application..."

# 编译应用程序
make

# 拷贝应用程序到指定目录
cp /usr/src/app/app /tmp/src/

run 脚本：

#!/bin/bash

echo "Starting application..."

# 启动应用程序
/tmp/src/app

save-artifacts 脚本：

#!/bin/bash

echo "Saving artifacts..."

# 保存应用程序的构建产物
cp /tmp/src/app /opt/app-root/src/

Dockerfile 文件：

FROM centos:7
MAINTAINER Your Name <your.email@example.com>

# 安装必要的依赖库
RUN yum -y install make gcc

# 拷贝 assemble、run、save-artifacts 脚本到镜像中
COPY s2i/bin/assemble s2i/bin/run s2i/bin/save-artifacts /usr/local/bin/

# 设置应用程序的工作目录
WORKDIR /opt/app-root/src

# 暴露应用程序的端口
EXPOSE 8080

# 设置应用程序的启动命令
CMD ["run"]

s2i 模板文件：

注：这只是一个简单的示例，具体的应用程序需要根据实际情况进行修改。
