Question

我也使用Chef 11（开源服务器）和chef-client 11。我试图搜索具有特定角色的节点。使用刀我能得到我希望使用的结果： knife search node "run_list:role\[cassandra\]"。我也可以使用食谱中的search(:node, "run_list:role\\[cassandra\\]")进行搜索。但是，如果我尝试使用属性访问该角色，我无法使其正常工作。我尝试了最明显的方法search(:node, "run_list:role\\[#{node[:role][:cassandra]}\\]")，并尝试在搜索行（query = 'run_list:role\[' + node[:cassandra][:seed_role]）之外撰写查询，但我得到了同样的错误。我在Chef-client编译阶段得到错误500（我认为）。这是我使用的代码和输出日志的一部分。

 # Searching for Cassandra nodes inside the same Chef environment
  cassandra_seeds = []
  cassandra_nodes_macs = []
  query = 'run_list:role\[' + node[:cassandra][:seed_role] + '\] AND chef_environment:#{node.chef_environment}'
  log query
  search(:node, query).each do |n|
#  search(:node, "run_list:role\\[cassandra\\]  AND \
#    chef_environment:#{node.chef_environment}").each do |n|
#  search(:node, "roles:*#{node[:cassandra][:seed_role]}  AND \
#    chef_environment:#{node.chef_environment}").each do |n|
    cassandra_seeds << n[:fqdn] unless n[:fqdn] == node[:fqdn]
  end

Answer 1

评论之后我玩了chef-shell（尝试在与食谱相同的上下文中搜索）

我发现有效的语法（没有引用角色名称）：

search(:node, 'run_list:role\[mysql-server-wso2\] AND chef_environment:I1')
search(:node, "run_list:role\\[mysql-server-wso2\\] AND chef_environment:I1")

对于变量插值，双引号方式听起来最简单。例如：

query = "run_list:role\\[#{node[:cassandra][:seed_role]}\\] AND chef_environment:#{node.chef_environment}"

您可以通过在此之后添加日志行来确保正确插值：

Chef::Log.info "Query is: #{query}"

旧答案：我不知道你为什么用单引号设置它，但它可能是你的问题：

 query = 'run_list:role\[' + node[:cassandra][:seed_role] + '\] AND chef_environment:#{node.chef_environment}'

单引号中，＃{node.chef_environment}不会被替换，并按原样发送到Chef服务器，服务器无法正常解析并因500错误而失败。

这样写的查询应该没问题：

query = "run_list:role['#{node[:cassandra][:seed_role]}'] AND chef_environment:#{node.chef_environment}"

Chef：在recipe中搜索节点返回错误500。
