用於 docker 鏡像驗證的 Puppet manifest 配置
我對 devops/ci/cd 很陌生，所以請耐心等待。
目前，我正在為 docker 圖像驗證設置一個 puppet manifest 配置。讓我嘗試佈局它：
我有一個具有以下配置的 puppet master 伺服器：
- Puppetmaster 版本：5.5.10-4ubuntu3
- 兩台伺服器都是linux 20.04
- 全部託管在 AWS 上
/etc/puppet/code/environments/production/manifests/site.pp
node default { include 'docker' docker::image { 'jorgemauriciodev/ubuntu-dockerfile-dev-v1': } }每次在 .pp 中嘗試新的驗證命令時，我都會使用以下命令重新啟動 puppet master 伺服器：sudo systemctl restart puppet-master
我在我的兩台伺服器（代理和主伺服器）上都安裝了一個名為 garethr-docker 的模組。
在從/代理伺服器上，我有這個鏡像 docker 鏡像存在並正在執行：jorgemauriciodev/ubuntu-dockerfile-dev-v1 第一步，我只想檢查我的從屬伺服器中是否存在該鏡像。稍後，我將確定它正在執行或使用 Dockerfile 建構。
在從/代理伺服器上，我執行：sudo puppet agent –test
我收到以下錯誤消息：
錯誤：無法從遠端伺服器檢索目錄：伺服器上的錯誤 500：伺服器錯誤：評估錯誤：評估函式呼叫時出錯，找不到類 ::docker 用於 ip-123-123-123-123.us-east- 2.compute.internal（文件：/etc/puppet/code/environments/production/manifests/site.pp，行：2，列：5）在節點 ip-123-123-123-123.us-east-2 .compute.internal 警告：未在失敗的目錄上使用記憶體錯誤：無法檢索目錄；跳過跑步
有人知道我對 puppet 清單文件有什麼問題嗎？
編輯1：
我做了一些建議的更改。現在，我的文件有一個不同的名稱並更改了內容：/etc/puppet/code/environments/production/manifests/init.pp
include 'docker' class { 'docker': version => 'latest', } docker::image { 'jorgemauriciodev/ubuntu-dockerfile-dev-v1': }仍然返回相同的錯誤消息。
這是完整的消息：

我使用以下命令在主伺服器和從/代理伺服器上安裝了更多模組：
sudo puppet module install puppetlabs-docker --version 4.1.2它仍然向我返回一條錯誤消息，但現在似乎它是一個不同的消息。所以，現在可能是一個語法問題。
這是消息的重要部分。
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: Class[Docker] is already declared; cannot redeclare (file: /etc/puppet/code/environments/production/manifests/init.pp, line: 3) (file: /etc/puppet/code/environments/production/manifests/init.pp, line: 3, column: 1) on node ip-123-123-123-123.us-east-2.compute.internal Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run除了這條消息，它仍然向我返回那些警告，但列表要大得多。但是，我認為目前這不是問題。
puppet 中的錯誤 500 意味著編寫錯誤的程式碼，您能否分享整個配置（init.pp），我可以從那裡告訴您。
