SSH Key Provisioner

TLDR(אמ;לק) – A Python CLI tool to provision SSH keys to your servers

I’ve been working on a new project lately, a Python CLI tool that helps you provision SSH keys to your servers. The idea came from a need to manage multiple SSH keys across different servers, and I wanted to make it easier to do so.

The tool is called ssh-key-provisioner and it’s available on GitHub. Here’s what it does:

  1. Reads your SSH keys from a specified directory
  2. Connects to your servers using SSH
  3. Adds your public keys to the authorized_keys file
  4. Supports multiple servers and multiple keys

Here’s how to use it:

# Install the tool
pip install ssh-key-provisioner

# Run the tool
ssh-key-provisioner --keys-dir ~/.ssh --servers server1.example.com server2.example.com

The tool will:

  1. Read all your public keys from the specified directory
  2. Connect to each server
  3. Add your keys to the authorized_keys file
  4. Show you the progress and any errors that occur

You can also specify a single key to provision:

ssh-key-provisioner --key ~/.ssh/id_rsa.pub --servers server1.example.com

The tool is still in development, but it’s already functional. I’m working on adding more features like:

  • Support for different SSH key types
  • Backup of existing authorized_keys file
  • Support for different SSH ports
  • Support for different SSH users

You can find the source code on GitHub: ssh-key-provisioner
