This is the command knife-ssl-fetch that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
knife-ssl-fetch - The man page for the knife ssl fetch subcommand.
The knife ssl fetch subcommand is used to copy SSL certificates from an HTTPS server to
the trusted_certs_dir directory that is used by knife and the chef-client to store trusted
SSL certificates. When these certificates match the hostname of the remote server, running
knife ssl fetch is the only step required to verify a remote server that is accessed by
either knife or the chef-client.
WARNING:
It is the user's responsibility to verify the authenticity of every SSL certificate
before downloading it to the trusted_certs_dir directory. knife will use any
certificate in that directory as if it is a 100% trusted and authentic SSL certificate.
knife will not be able to determine if any certificate in this directory has been
tampered with, is forged, malicious, or otherwise harmful. Therefore it is essential
that users take the proper steps before downloading certificates into this directory.
Syntax
This subcommand has the following syntax:
$ knife ssl fetch URI_FOR_HTTPS_SERVER
