Chef Node API与/ nodes / nodename一样,将返回完整的节点对象,如:
{
"name": "node_name",
"chef_environment": "_default",
"run_list": [
"recipe[recipe_name]"
]
"json_class": "Chef::Node",
"chef_type": "node",
"automatic": { ... },
"normal": { "tags": [ ] },
"default": { },
"override": { "cookbook1_name"=>{
"attribute1"=>"overridevalue"
}}
}
我正在尝试使用Chef :: Search :: Query.search REST API来返回一些必需的列而不是完整的节点对象。例如:
Chef::Search::Query.new("server url").search(:node, '*:*', :filter_result => {'name' => ['name'] } )
它只能返回节点名称,但是当我尝试添加覆盖数据时,它总是返回null ...
Chef::Search::Query.new("server url").search(:node, '*:*', :filter_result => {'name' => ['name'], 'override' => ['override'] } )
似乎filter_result可以用于像string或array这样的类型,但是override是一个json对象,如何在结果中包含它?
谢谢!
答案 0 :(得分:1)
et filter_result
中的关键路径是针对合并的属性表单运行的。你会想要'attribute1' => ['cookbook1_name', 'attribute1']
。

直接举例:
$ knife node show foo -z -l -Fj
{
"name": "foo",
"chef_environment": "_default",
"run_list": [
]
,
"normal": {
},
"default": {
},
"override": {
"key1": {
"key2": "value"
}
},
"automatic": {
}
}
$ knife exec -z -E 'puts search(:node, "*:*").inspect'
