The "knife bootstrap" command is a command-line utility in Chef, a configuration management tool. It is used to install and configure the Chef client on a remote server or node.
The command "knife bootstrap ${fqdn_or_ip}" is a specific usage of the "knife bootstrap" command. It is used to bootstrap a server by connecting to it over SSH, installing the Chef client, and configuring it to communicate with a Chef server.
The placeholder "${fqdn_or_ip}" should be replaced with the fully qualified domain name (FQDN) or IP address of the server or node you want to bootstrap. This identifies the target server that the command will connect to.
By running this command, Chef will remotely install the Chef client on the target server and perform initial configuration, such as registering it with the Chef server. This allows the node to communicate with the Chef server and receive instructions on how to configure itself according to the desired infrastructure defined in Chef cookbooks.
Note: The successful execution of this command assumes that your workstation has ChefDK or the Chef development kit installed, and it is properly configured to communicate with the Chef server.
