Since the chef-client provisioner is cleaning the node and client at the chef-server from the provisioned node
it needs to have a flexible configuration
This is replacing the used knife flags: -s '<chef-server-url>' -k '/tmp/packer-chef-client/client.pem' -u '<client-name>'
and puts their values into a generated knife.rb
Additionally the knife.rb may include the optional ssl_verify_mode attribute to enable the verify mode verify_none
Background:
When deleting node and client to a self-hosted chef-server using self signed cerfiticates the usage of
knife node delete <node-name> -y -s '<chef-server-url>' -k '/tmp/packer-chef-client/client.pem' -u '<client-name>'
will lead into a ssl verification failure.
The error output of the knife call is somthing like:
