The command "kops create secret sshpublickey ${key_name} -i ${~--ssh-id_rsa-pub}" is used to create a secret containing an SSH public key for use with Kubernetes Operations (kops).

Let's break down the command:

• "kops" refers to the command-line tool kops, which is used to install and manage Kubernetes clusters on cloud infrastructure.
• "create secret sshpublickey" is the specific command within kops for creating a secret containing an SSH public key.
• "${key_name}" is a placeholder for the name you want to give to the secret. You should replace it with an actual name, like "my-ssh-key".
• "-i" is an option specifying the input source for the public key.
• "${~--ssh-id_rsa-pub}" is a placeholder for the source of the SSH public key file. It seems like there might be a typo in the command - "~" should be a tilde (~), representing the home directory. So, it's trying to reference the file "~/.ssh/id_rsa.pub", which is the default location for the SSH public key file. This will need to be corrected to work properly.

To use this command, you need to replace "${key_name}" and fix the "~--ssh-id_rsa-pub" part with the correct SSH public key file path. For instance, if your SSH public key file is located at "/home/user/.ssh/my_key.pub", the corrected command would be:

"kops create secret sshpublickey my-ssh-key -i /home/user/.ssh/my_key.pub"

This will create a secret named "my-ssh-key" in kops, containing the provided SSH public key.
