resources - Chef : Modify existing resource from another cookbook

Question

我有两本 cooking 书:elasticsearch 和 curator。

Elasticsearch 说明书安装并配置 Elasticsearch。以下资源(来自 elasticsearch Recipe )必须从 curator Recipe 进行修改:

elasticsearch_configure 'elasticsearch' do
    configuration ({
        'http.port' => port,
        'cluster.name' => cluster_name,
        'node.name' => node_name,
        'bootstrap.memory_lock' => false,
        'discovery.zen.minimum_master_nodes' => 1,

        'xpack.monitoring.enabled' => true,
        'xpack.graph.enabled' => false,
        'xpack.watcher.enabled' => true
    })
end

我需要在 curator Cookbook 上修改它并添加一行:

'path.repo' => (["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"])

我怎样才能做到这一点？

Answer 1

我最初打算向您指出 chef-rewind gem，但这实际上指向 edit_resource现已内置于 Chef 中的提供程序。一个基本的例子:

# cookbook_a/recipes/default.rb
file 'example.txt' do
  content 'this is the initial content'
end

.

# cookbook_b/recipes/default.rb
edit_resource! :file, 'example.txt' do
  content 'modified content!'
end

如果这两个内容都在 Chef run_list 中，则 example.txt 中的实际内容是已编辑资源的内容，修改后的内容!.

在没有完全测试您的案例的情况下，我假设可以以相同的方式使用提供程序，如下所示:

edit_resource! :elasticsearch_configure, 'elasticsearch' do
    configuration ({
        'http.port' => port,
        'cluster.name' => cluster_name,
        'node.name' => node_name,
        'bootstrap.memory_lock' => false,
        'discovery.zen.minimum_master_nodes' => 1,

        'xpack.monitoring.enabled' => true,
        'xpack.graph.enabled' => false,
        'xpack.watcher.enabled' => true,

        'path.repo' => ["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"]
    })
end
