收集所有rpm依赖项以部署项目 [英] Collect all rpm dependencies to deploy a project

问题描述

我需要将软件项目（打包为rpm）从开发者机器部署到服务器中。我正在使用Fedora 23以及dnf软件包管理器。在部署到服务器之前，我必须收集所有rpm的依赖关系。由于内部监管，服务器无法连接到互联网（但是我可以在其上安装ssh）。运行存储库镜像等不是一个选项。恐怕我只需要收集开发者机器上的所有依赖关系，并将它们scp（或可以）安装到服务器上，然后安装在服务器上。

I need to deploy a software project (packaged as an rpm) from a developer machine into a server. I'm using Fedora 23, along with the dnf package manager. I have to collect all dependencies of my rpm before I deploy to the server. The server can't be connected to the internet due to internal regulation (But I can ssh onto it). Running repository mirrors, etc. is not an option. I'm afraid I just have to collect all dependencies on the developer machine, scp (or ansible) them to the server and install them on the server.

我希望dnf中的 - installroot 选项可能会有很大的帮助，因为我可以检索将被安装到dnf认为是空系统的所有rpms。但是这不行。

I hoped that --installroot option in dnf could be of much help, as I could retrieve all rpms that would get installed into what dnf thinks is an empty system. This however doesn't work.

mkdir foo&& sudo dnf install --installroot = $ PWD / foo golang

给出错误：

无法为repo'fedora'同步缓存

为什么会失败？我有什么选择？

Why does this fail? What are my options?

我想看到一个优雅而强大的解决方案。我不想在服务器上安装任何东西（我最乐意做一个单一的scp，后跟一个或两个命令通过ssh）。 rpm + yum / dnf魔术的组合将是巨大的，但其他解决方案，包括apt + deb也是很有意思的。我不喜欢使用docker，我强烈反对运行任何其他基础设施（docker注册表，rpm镜像等）。

I'd like to see an elegant and robust solution. I'd prefer not to install anything on the server (I'd be most happy to do a single scp followed by one or two commands over ssh). A combination of rpm + yum/dnf magic would be great, but other solutions, including apt + deb are also of interest. I'd prefer not to use docker, and I'm strongly against running any additional infrastructure (docker registry, rpm mirror, etc.)

推荐答案

这是一个（临时的，轻微测试的）脚本（假设您已经安装了rpm系统）来生成安装给定软件包所需的所有rpm软件包名称的列表（脚本假定为bash ，编辑以品尝）

Here is a (ad hoc, lightly tested) script (assuming you have an already installed rpm system) to generate the list of all the rpm package names needed to install a given package (the script assumes goal="bash", edit to taste).

将输出名称输入到dnf / yum进行安装。

Feed the output names to dnf/yum to install.

#!/bin/sh
goal=bash
deps=$(rpm -q --qf '[%{REQUIRENAME}\n]'  $goal | egrep -v '^(rpmlib|rtld|config|/)')
goals=
while true; do
  subs=$(rpm -q --qf '%{NAME}\n' --whatprovides $deps | sort -u | tr '\n' ' ')
  if [ ."$subs" = ."$goals" ]; then
    echo "--- packages needed"
    echo "$goals" | tr ' ' '\n'
    exit 0
  fi
  goals=$(echo $goals $subs | tr ' ' '\n' | sort -u | tr '\n' ' ')
  for sub in $subs; do
    subdeps=$(rpm -q --qf '[%{REQUIRENAME}\n]' $sub | egrep -v '^(rpmlib|rtld|config|/)')
    deps=$(echo $deps $subdeps | sort -u)
  done
done
