9.4. Adding dynamic metadata to instances

Procedure

1. Open your Compute environment file.

2. Add DynamicJSON to the vendordata provider module:

   parameter_defaults:
     ComputeExtraConfig:
       nova::config::nova_config:
         ...
         api/vendordata_providers:
           value: StaticJSON,DynamicJSON

3. Specify the REST services to contact to generate the metadata. You can specify as many target REST services as required, for example:

   parameter_defaults:
     ComputeExtraConfig:
       nova::config::nova_config:
         ...
         api/vendordata_providers:
           value: StaticJSON,DynamicJSON
         api/vendordata_dynamic_targets:
           value: target1@http://127.0.0.1:125
         api/vendordata_dynamic_targets:
           value: target2@http://127.0.0.1:126

   The Compute service generates the JSON file, vendordata2.json, to contain the metadata retrieved from the configured target services, and stores it in the config drive directory.

   注記

   Do not use the same name for a target service more than once.

4. Save the updates to your Compute environment file.

5. Add your Compute environment file to the stack with your other environment files and deploy the overcloud:

   (undercloud)$ openstack overcloud deploy --templates \
    -e [your environment files] \
    -e /home/stack/templates/<compute_environment_file>.yaml \
