我对 devops/ci/cd 还很陌生，所以请耐心等待。
目前，我正在为 docker 镜像验证设置一个 puppet 清单配置。让我尝试布局一下：
我有一个 Puppet 主服务器，其配置如下：
- 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': }
}
每次我在 .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（代理服务器和主服务器）上都安装了一个名为 garethr-docker 的模块。
在从属/代理服务器上，我有此镜像 docker 镜像并正在运行：jorgemauriciodev/ubuntu-dockerfile-dev-v1 第一步，我只想检查该镜像是否存在于我的从属服务器中。稍后，我将弄清楚以确保它正在运行或使用 Dockerfile 构建。
在从属/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 ip-123-123-123-123.us-east-2.compute.internal 的类 ::docker （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 上警告：未在失败的目录上使用缓存错误：无法检索目录；跳过运行
有谁知道我的 Puppet 清单文件出了什么问题？
编辑1：
我按照建议做了一些更改。现在，我的文件有一个不同的名称，并且更改了内容：/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。
以下是完整信息：

编辑2：
我使用以下命令在主服务器和从属/代理服务器上安装了更多模块：
sudo puppet module install puppetlabs-docker --version 4.1.2
它仍然返回错误消息，但现在似乎是一个不同的消息。所以，现在可能是语法问题。
这是该消息的重要部分。
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
除了这条消息之外，它还会向我返回那些警告，但列表要长得多。不过，我认为这目前不是一个值得担心的问题。
答案1
puppet 中的错误 500 意味着代码编写不正确，您能否分享整个配置（init.pp）以便我可以从那里告诉您。
class { 'docker':
version => 'latest',
}
docker::image { 'jorgemauriciodev/ubuntu-dockerfile-dev-v1': }
