将ruby应用程序部署到Cloud Foundry，rubygems失败

问题描述

我是红宝石的新手。我正在部署一个ruby应用程序，该应用程序从Slack读取Bug ID，将请求发送到Jira，并向Slack发送响应，并附上Bug详细信息。在将此应用程序部署到Cloud Foundry时遇到问题。我在用， cloud Foundry build pack版本：1.8.25 捆绑器2.1.4 红宝石2.7.0 红宝石3.1.4。

我有一个包含命令bundle exec rackup config.ru -p $PORT的proc文件，当我执行cf push时，出现以下错误：

让我知道是否需要其他信息。

在运行“捆绑安装”尝试安装gem时，发生此故障。

解决方法

目前提供的信息尚不清楚，但是存在以下错误：

2020-10-06T23：07：22.40-0400 [STG / 0]错误/tmp/rubygems270167546/lib/rubygems/core_ext/kernel_require.rb:92：在require': /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: version 中找不到OPENSSL_1_1_1（由/tmp/contents329128731/deps/0/ruby/lib/ruby/2.7.0/x86_64-linux/openssl.so）-/tmp/contents329128731/deps/0/ruby/lib/ruby/2.7.0/x86_64-linux /openssl.so（LoadError）

看起来您有一个需要在cflinuxfs2上使用cflinuxfs3的构建包。这两个堆栈具有不同的OpenSSL版本，cflinuxfs3具有1.1.1。

切换堆栈至少应允许您克服此错误。

cf push -s cflinuxfs3或在manifest.yml中设置stack: cflinuxfs3。

对于它的价值，在我写这篇cflinuxfs2的时候，它已经过时了，已经超出了支持范围。如果您使用的平台仍默认为cflinuxfs2堆栈，或者甚至可以选择使用该平台，则应与您的平台运营团队讨论如何尽快升级。
