Cloudify - Openstack-Plugin - How to grant permissions to write/read key to the path specified into KeyPair Cloudify building block

Question

when i try to deploy a blueprint with a keypair block, Cloudify returns the subsequent error:

Task failed 'nova_plugin.keypair.create' -> [Errno 13] Permission denied: '/root/key.key'

Where '/root/key.key' is the full path where i want the private key will be written on Cloudify manager machine.

I think that the issue is generated becouse of Cloudify itself does'nt knows access credentials of the cloudify manager machine. So I ask you how can I specify them to be used by Cloudify to write correctly the key in specified path.

Answer 1

The user cloudify is using doesn't have permissions to write to /root. We usually put our key pairs in /etc/cloudify.

Answer 2

All manager-side plugin operations in Cloudify, are run as the user cfyuser.

You are getting this error because the user cfyuser doesn't have permissions to write into /root.

cfyuser is created with /etc/cloudify as its home directory, and by default, it has access to write to it.
