inPack Spec Define

inPack Spec 配置以文本形式放置在项目根目录的指定位置: project/inpack.spec 或 project/misc/inpack/inpack.spec , 打包程序会自动在这两个位置读取 inpack.spec 并作后续操作.

一个标准的 inpack.spec 文件可以参考一个 nginx inpack.spec 实例，如下:

[project]
name = nginx
version = 1.12.2
vendor = nginx.org
homepage = http://nginx.org/
groups = dev/sys-srv
description = High Performance Load Balancer, Web Server, Reverse Proxy

%build

PREFIX="{{.project__prefix}}"

cd {{.inpack__pack_dir}}/deps

if [ ! -f "nginx-{{.project__version}}.tar.gz" ]; then
    wget http://nginx.org/download/nginx-{{.project__version}}.tar.gz
fi
if [ -d "nginx-{{.project__version}}" ]; then
    rm -rf nginx-{{.project__version}}
fi
tar -zxf nginx-{{.project__version}}.tar.gz

cd nginx-{{.project__version}}

inpack.spec - project

[project] 标识定义包的基本信息，比如包名,版本号,描述等等,…

[project]
name = nginx
version = 1.12.2
vendor = nginx.org
homepage = http://nginx.org/
groups = dev/sys-srv
description = High Performance Load Balancer, Web Server, Reverse Proxy

其中 groups 为 inPack 的分类标识，完整的定义清单如下:

Name	Description
app/biz	Business
app/co	Collaboration
app/prod	Productivity
app/dev	Development Tools
app/other	App Others
dev/web-static	Web Frontend Static Library
dev/web-lib	Web Backend Library
dev/sys-lib	System Library
dev/db	Database Server or Service
dev/stor	Storage Server or Service
dev/sys-srv	System Server or Service
dev/sys-runtime	System Runtime Environments
dev/other	Dev Others

inpack.spec - build

%build 标识定义编译脚本,　如

%build
PREFIX="{{.project__prefix}}"

cd {{.inpack__pack_dir}}/deps

./configure --prefix=/home/action/apps/nginx
make -j4
... ...

在 build 脚本块中，包含动态模版参数，格式为 {{.var_name}}, 其完整的参数清单如下:

Name	Description
buildroot	打包编译的临时目录
inpack__pack_dir	当前打包项目的物理路径
project__version	当前打包项目的版本号
project__release	当前打包项目的发行号
project__dist	当前打包环境的操作系统别名 (目前仅支持 el7, 兼容 CentOS7 和 rhel 7)
project__arch	当前打包环境的硬件架构，固定为 x64 (即 x86_64或amd64)
project__prefix	项目安装的默认根路径，部分软件在运行时依赖这个参数，在 sysinner 系统下统一设置为 /home/action/apps/project-name

inpack.spec - files

%files 标识定义静态文件,　用于批量复制相同路径的文件到目标包，一般用于静态文件，或者不需要编译的脚本类文件,如

%files
/public/static/
/libs/
