ruby - 自定义 Chef 资源在 ubuntu 中启动 newrelic-infra

Question

最初我开始查看 Configure New Relic Infrastructure using Chef设置newrelic infra chef cookbook对于我使用 chef solo 的项目，经过一些研究，我发现 Recipe 中的依赖项不再受支持。

所以我决定在 Recipe 中编写一个自定义资源，这样我就可以利用 Chef 幂等性。

我试过following steps在 下为 Ubuntu 安装 在我的 ubuntu 盒子中并验证了新的 relic-infra 安装:

现在我正在尝试编写这样的 Chef 资源:

Step1:创建一个配置文件，并添加您的许可证 key :

echo "license_key: YOUR_LICENSE_KEY" | sudo tee -a /etc/newrelic-infra.yml

在我的第 1 步配方中添加了此资源 block :

file '/etc/newrelic-infra.yml' do
  content 'license_key: added_key_here'
  mode '0755'
  owner 'root'
  group 'root'
end

Step2:启用New Relic的GPG key :

curl https://download.newrelic.com/infrastructure_agent/gpg/newrelic-infra.gpg | sudo apt-key add -

在我的第 2 步配方中添加了此资源 block :

apt_repository 'newrelic_key' do
  uri 'https://download.newrelic.com/infrastructure_agent/gpg'
  trusted true
  key 'https://download.newrelic.com/infrastructure_agent/gpg/newrelic-infra.gpg'
end

我通过使用以下命令列出 key 在本地框中验证了此步骤:

sudo apt-key list

第 3 步:使用适用于您的分发版本的命令创建代理的 apt 存储库:

printf "deb [arch=amd64] https://download.newrelic.com/infrastructure_agent/linux/apt bionic main" | sudo tee -a /etc/apt/sources.list.d/newrelic-infra.list

在我的第 3 步配方中添加了此资源 block :

file '/etc/apt/sources.list.d/newrelic-infra.list' do
  content 'deb [arch=amd64] https://download.newrelic.com/infrastructure_agent/linux/apt bionic main'
  mode '0755'
  owner 'root'
  group 'root'
end

第 4 步:更新您的 apt 缓存并运行安装脚本:

sudo apt-get update
sudo apt-get install newrelic-infra -y 

在我的第 4 步配方中添加了此资源 block :

apt_update
apt_package 'newrelic-infra'

错误:

但是安装失败并出现以下错误:

我运行了我的流浪文件，它成功地适用于每一步，但在最后的安装步骤中失败了......我做错了什么？任何故障排除提示都会有所帮助。谢谢!

Answer 1

首先，您可以使用 apt_repository 将步骤 2 和 3 组合在一起通过使用 arch和 distribution .

如果您阅读 apt_repository文档，您可以看到您甚至可以删除 apt update在第 4 步

Adding a new repository will update the APT package cache immediately.

其次，回到你的问题...

通过查看您的日志，特别是

default:       execute[apt-get -q update] (/opt/chefdk/embedded/lib/ruby/gems/2.5.0/gems/chef-14.4.56/lib/chef/provider/apt_update.rb line 70) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '100'

看来您没有在节点上运行 chef-client，而是使用 chef-dk。确保您正在运行 chef-client (或现在的 Chef 基础设施客户端)在您想要聚合的节点内。

你可以运行chef-client通过指定 log_level 在更高的日志级别显示更多关于执行的信息

The level of logging to be stored in a log file. Possible levels: auto (default), debug, info, warn, error, or fatal. Default value: warn (when a terminal is available) or info (when a terminal is not available).

我希望它能帮助你解决你的问题
