用于 docker 镜像验证的 Puppet manifest 配置

我对 devops/ci/cd 很陌生，所以请耐心等待。

目前，我正在为 docker 图像验证设置一个 puppet manifest 配置。让我尝试布局它：

我有一个具有以下配置的 puppet master 服务器：

• Puppetmaster 版本：5.5.10-4ubuntu3
• 两台服务器都是linux 20.04
• 全部托管在 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 中尝试新的验证命令时，我都会使用以下命令重新启动 puppet master 服务器：sudo systemctl restart puppet-master

我在我的两台服务器（代理和主服务器）上都安装了一个名为 garethr-docker 的模块。

在从/代理服务器上，我有这个镜像 docker 镜像存在并正在运行：jorgemauriciodev/ubuntu-dockerfile-dev-v1 第一步，我只想检查我的从属服务器中是否存在该镜像。稍后，我将确定它正在运行或使用 Dockerfile 构建。

在从/代理服务器上，我运行：sudo puppet agent –test

我收到以下错误消息：

错误：无法从远程服务器检索目录：服务器上的错误 500：服务器错误：评估错误：评估函数调用时出错，找不到类 ::docker 用于 ip-123-123-123-123.us-east- 2.compute.internal（文件：/etc/puppet/code/environments/production/manifests/site.pp，行：2，列：5）在节点 ip-123-123-123-123.us-east-2 .compute.internal 警告：未在失败的目录上使用缓存错误：无法检索目录；跳过跑步

有人知道我对 puppet 清单文件有什么问题吗？

编辑1：

我做了一些建议的更改。现在，我的文件有一个不同的名称并更改了内容：/etc/puppet/code/environments/production/manifests/init.pp

include 'docker'
class { 'docker':
  version => 'latest',
}
docker::image { 'jorgemauriciodev/ubuntu-dockerfile-dev-v1': }

仍然返回相同的错误消息。

这是完整的消息：

编辑2：

我使用以下命令在主服务器和从/代理服务器上安装了更多模块：

sudo puppet module install puppetlabs-docker --version 4.1.2

它仍然向我返回一条错误消息，但现在似乎它是一个不同的消息。所以，现在可能是一个语法问题。

这是消息的重要部分。

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

除了这条消息，它仍然向我返回那些警告，但列表要大得多。但是，我认为目前这不是问题。
