How to Securely Deploy Your App to a Server Using GitHub Actions

# How to Securely Deploy Your App to a Server Using GitHub Actions Manual SSH deployments are easy to break and hard to scale. This guide explains how to automate deployments with GitHub Actions using secure secrets. ## Required Secrets Set five repository secrets: SERVER_HOST, SERVER_USER, SERVER_PORT, SERVER_SSH_KEY, and SERVER_RESTART_COMMAND. ## Generate Dedicated SSH Key Create an ED25519 key pair specifically for deployment automation. Add the public key to authorized_keys on the server and store the private key in GitHub Actions secrets. ## Restart Command Options Use a restart command based on your runtime stack, such as systemd, supervisor, or nginx reload only for static apps. ## Deployment Checklist Use a repeatable checklist so every environment can be configured safely and consistently.
