Hi All, I am working with OpenStack Pike and cloud-init 21.1. I am able to successfully pass dynamic vendor data to the config drive of an instance. However, cloud-init 21.1 just reads all the 'x' bytes of the vendor_data2.json but it doesn't execute the contents of the json. Although, static vendor data works perfectly fine and the YAML file in the JSON is executed as expected by cloud-init 21.1 * Now, the person who wrote the code for handling dynamic vendordata in cloud-init (https://github.com/canonical/cloud-init/pull/777) says that the JSON cloud-init expects is of the form:
{"cloud-init": "#cloud-config\npackage_upgrade: True\npackages:\n - black\nfqdn: cloud-overridden-by-vendordata2.example.org."}
* I believe that the JSON should have another outer key (as mentioned here https://specs.openstack.org/openstack/nova-specs/specs/newton/implemented/ve...) which is the name of the microservice specified in nova.conf file and that the inner key should be cloud-init. In nova.conf: vendordata_dynamic_targets=name1@ http://example.com,name2@http://example2.com <http://example.com,name2@http//example2.com> {
"name1": { "cloud-init": "#cloud-config\n..." }, "name2": { "cloud-init": "#cloud-config\n..." } }
Who is right and who is wrong?
