amazon-web-services - Chef 运行期间的 AWS OpsWorks 层

Question

我想将自定义 JSON 传递给我的厨师运行，但显然这只能为整个堆栈完成。我可以将 JSON 上的图层名称/ID 与所需数据一起使用，但我如何检查厨师正在处理的实例的图层？

Answer 1

解决了。SSH 连接到我的实例，然后：

sudo opsworks-agent-cli get_json

这向我展示了与 Chef Custom JSON 合并的 Opsworks JSON……还有我的图层名称：

node["opsworks"]["instance"]["layers"][0]

然后我在我的食谱中使用了一些逻辑......

node_instance = search(:node, "hostname:#
{node['hostname'].upcase}").first
Chef::Log.info "This is an instance object as returned by Chef Server. 
EC2 Instance ID is #{node_instance['ec2']['instance_id']}"

aws_instance = search(:aws_opsworks_instance, "hostname:#
{node['hostname'].upcase}").first
Chef::Log.info "This is the AWS OpsWorks instance object. It has AWS 
OpsWorks specific attributes, like the Layer IDs for the instance: #
{aws_instance['layer_ids'].join(',')}"

aws_instance['layer_ids'].each do |layer_id|
  layer = search(:aws_opsworks_layer, "layer_id:#{layer_id}").first
  Chef::Log.info "The instance belongs to layer #{layer['layer_id']}, 
it's name is #{layer['name']}"
