setup_scripts

contains some of my scripts to start development faster. Since my build and development environment is getting bigger, I wanted to have some reproducible scripts for setting up SSH connections and installing software. In future, I plan to extend this repo with some additional, reusable functions on demand, so I don't have to remind how to do this repeating tasks.

ssh-keys

Generates SSH keys on a client PC and deploys them to the build/server PC.

Options

Flag	Description
--generate	Generate a new SSH key of the specified type (rsa, dsa, ecdsa, ed25519)
--key-path	Directory where keys are stored/generated (defaults to ~/.ssh)
--deploy-to-host	Deploys the public key to <user>@<host> via SSH
--password_type	Password input type: prompt or dotenv
--dotenv-file	Path to .env file containing PASSWORD=yourpassword

Usage

Generate a new SSH key

ssh-keys --generate rsa --key-path ~/.ssh

Deploy an existing key

If a key already exists in --key-path, it is detected automatically — no --generate needed:

ssh-keys --deploy-to-host user@host --key-path ~/.ssh

Generate and deploy in one step

ssh-keys --generate ed25519 --key-path ~/.ssh --deploy-to-host user@host

Deploy with a dotenv password file

ssh-keys --deploy-to-host user@host --password_type dotenv --dotenv-file /path/to/.env

The .env file requires just one line:

PASSWORD=yourpassword

How it works

• Key generation: uses ssh-keygen to create keys in --key-path.
• Deployment: uses paramiko to copy the public key to ~/.ssh/authorized_keys on the remote host.
• Key detection: when --deploy-to-host is used without --generate, the script scans --key-path for existing .pub files (id_rsa.pub, id_ed25519.pub, etc.) to determine the key type automatically.
• Password: prompted interactively by default, or read from a .env file when --password_type dotenv is specified.

Testing

Tests are implemented in tests/ directory.

To install development dependencies (pytest, python-dotenv etc.):

pip install -e ".[dev]"

To run tests:

pytest

Or with coverage reporting:

pytest --cov=scripts --cov-report=term-missing

To build the package:

pip install build
python -m build

Improvements / Nice to have

If you have any suggestions to improve code/tests, feel free to create a PR for the scripts or write me a message. More specifically:

• I want to test password prompt automatically.
• add a connection check at the end of test_ssh_keys_deployment.
