Deployment

Deploy your Aegis Stack project to a remote server with a single command. The deployment system handles file syncing, Docker builds, and service orchestration over SSH.

Prerequisites

  • A VPS or server with SSH access (Ubuntu, Debian, or Fedora)
  • SSH key authentication configured for your server
  • rsync installed locally (included on macOS and most Linux distributions)
  • A domain (optional, required for TLS/HTTPS)

Quick Start

# 1. Initialize deployment config
aegis deploy-init --host 192.168.1.100

# 2. Provision the server (installs Docker, configures firewall)
aegis deploy-setup

# 3. Deploy your application
aegis deploy

Your application is now running at http://your-server-ip.

Configuration

Deployment settings are stored in .aegis/deploy.yml, created by deploy-init:

# .aegis/deploy.yml
server:
  host: 192.168.1.100
  user: root
  path: /opt/my-project

docker:
  context: my-project-remote

# Optional: backup settings (defaults shown)
backup:
  keep_count: 5           # Number of backups to retain
  include_database: true  # pg_dump before deploy

# Optional: health check after deploy (defaults shown)
health_check:
  retries: 3              # Number of retry attempts
  auto_rollback: true     # Rollback on failed health check
Field Description
server.host Server IP address or hostname
server.user SSH user (default: root)
server.path Application directory on server (default: /opt/{project-name})
docker.context Docker context name (used by generated Makefile deploy-* targets)
backup.keep_count Number of backups to keep on server (default: 5)
backup.include_database Include PostgreSQL dump in backup (default: true)
health_check.retries Number of health check attempts (default: 3)
health_check.auto_rollback Auto-rollback on failed health check (default: true)

All backup and health_check fields are optional — missing fields use defaults. Existing deploy.yml files work without changes.

Git-ignore deploy config

Add .aegis/ to your .gitignore to keep deployment config out of version control. deploy-init will remind you if it's missing.

Command Reference

aegis deploy-init

Initialize deployment configuration for a project.

Usage: 

aegis deploy-init [OPTIONS]

Options:

  • --host, -h TEXT — Server IP address or hostname (prompted if not provided)
  • --user, -u TEXT — SSH user for deployment (default: root)
  • --path, -p TEXT — Deployment path on server (default: /opt/{project-name})
  • --project-path TEXT — Path to the project (default: current directory)

Examples: 

# Interactive (prompts for host)
aegis deploy-init

# Specify host directly
aegis deploy-init --host 192.168.1.100

# Custom user and path
aegis deploy-init --host myserver.com --user deploy --path /srv/myapp

aegis deploy-setup

Provision a remote server for deployment. Run this once on a fresh server before your first deploy.

Usage: 

aegis deploy-setup [OPTIONS]

Options:

  • --project-path TEXT — Path to the project (default: current directory)

What it does:

  1. Verifies SSH connectivity (adds host key if needed)
  2. Copies scripts/server-setup.sh to the server
  3. Runs the setup script, which:
    • Installs Docker and Docker Compose plugin
    • Installs uv (Python package manager)
    • Installs build tools (build-essential / gcc)
    • Configures firewall (ports 22, 80, 443)
    • Sets up Docker daemon with log rotation
    • Creates application directory with proper permissions
    • Applies system optimizations (file limits, TCP BBR)

Examples: 

aegis deploy-setup

Requires ingress component

The server-setup.sh script is generated when the ingress component is included. If you see "Server setup script not found", add ingress first: aegis add ingress.

aegis deploy

Deploy (or redeploy) the application to the configured server.

Usage: 

aegis deploy [OPTIONS]

Options:

  • --build / --no-build — Build Docker images before deploying (default: --build)
  • --backup / --no-backup — Create backup before deploying (default: --backup)
  • --health-check / --no-health-check — Run health check after deploying (default: --health-check)
  • --project-path TEXT — Path to the project (default: current directory)

What it does:

  1. Creates a backup of the current deployment (files + database)
  2. Syncs files to the server via rsync
  3. Copies .env file separately (excluded from rsync for safety)
  4. Stops existing services with docker compose down
  5. Builds and starts services with production compose overrides
  6. Restarts Traefik if the ingress component is present (ensures container re-discovery)
  7. Runs health check against /health/ endpoint
  8. Auto-rollback if health check fails — restores the backup from step 1

Excluded from sync:

Files and directories excluded from the rsync transfer:

  • .git — Git history
  • __pycache__ — Python cache
  • .venv — Virtual environment
  • *.pyc — Compiled Python files
  • .pytest_cache — Test cache
  • .ruff_cache — Linter cache
  • data/ — Local database files
  • .env — Environment file (copied separately)
  • .aegis/ — Deploy configuration
  • backups/ — Server-side backups

Examples: 

# Full deploy with build (backup + health check enabled by default)
aegis deploy

# Skip image rebuild (faster, uses cached images)
aegis deploy --no-build

# Deploy without backup or health check (original behavior)
aegis deploy --no-backup --no-health-check

aegis deploy-backup

Create a backup of the currently deployed application on the remote server.

Usage: 

aegis deploy-backup [OPTIONS]

Options:

  • --project-path TEXT — Path to the project (default: current directory)

What it does:

  1. Creates a timestamped backup directory on the server
  2. Copies all deployed files into the backup via server-side rsync
  3. Dumps the PostgreSQL database if a postgres container is running
  4. Prunes old backups beyond the retention count (default: 5)

SQLite databases are automatically included in the file backup since they live in the deploy directory.

Examples: 

aegis deploy-backup

aegis deploy-backups

List available deployment backups on the remote server.

Usage: 

aegis deploy-backups [OPTIONS]

Options:

  • --project-path TEXT — Path to the project (default: current directory)

Example output: 

Backups on 143.198.20.208 (3 total):

  Timestamp                Size         Database

Usage: 

aegis deploy-rollback [OPTIONS]

Options:

  • --backup, -b TEXT — Backup timestamp to rollback to (default: latest)
  • --project-path TEXT — Path to the project (default: current directory)

What it does:

  1. Stops all running services
  2. Restores files from the backup snapshot
  3. Restores the PostgreSQL database if a dump exists in the backup
  4. Rebuilds and starts all services
  5. Restarts Traefik if present

Examples: 

# Rollback to the most recent backup
aegis deploy-rollback

# Rollback to a specific backup
aegis deploy-rollback --backup 2026-03-11_183045

aegis deploy-logs

Usage: 

aegis deploy-logs [OPTIONS]

Options:

  • --follow / --no-follow, -f — Follow log output in real-time (default: --follow)
  • --service, -s TEXT — Show logs for a specific service
  • --project-path TEXT — Path to the project (default: current directory)

aegis deploy-shell --service redis

# Shell into Traefik
aegis deploy-shell -s traefik

Opens a /bin/bash session inside the container via SSH.

TLS/HTTPS with Let's Encrypt

Enable automatic HTTPS on a deployed project using aegis ingress-enable.

aegis ingress-enable

Configure TLS (HTTPS) with automatic Let's Encrypt certificates.

Usage: 

aegis ingress-enable [OPTIONS]

Options:

  • --domain, -d TEXT — Domain name for the TLS certificate (e.g., example.com)
  • --email, -e TEXT — Email for Let's Encrypt certificate notifications
  • --project-path, -p TEXT — Path to the project (default: current directory)
  • --yes, -y — Skip confirmation prompts

What it does:

  1. Adds the ingress component if not already present
  2. Configures traefik/traefik.yml with HTTPS entrypoint and ACME resolver
  3. Updates Docker Compose labels for TLS routing
  4. Adds traefik-letsencrypt Docker volume for certificate storage
  5. Configures HTTP → HTTPS redirect

Examples: 

# Interactive (prompts for domain and email)
aegis ingress-enable

# Fully specified
aegis ingress-enable --domain example.com --email admin@example.com

# Non-interactive
aegis ingress-enable -d example.com -e admin@example.com -y

# On a different project
aegis ingress-enable -p ../my-project -d example.com

Full TLS Workflow

# 1. Enable TLS on your project
aegis ingress-enable --domain example.com --email admin@example.com

# 2. Deploy to your server
aegis deploy

# 3. Ensure DNS is configured
#    Point your domain's A record to your server IP

# 4. Certificates auto-provision on first request
#    Traefik handles Let's Encrypt automatically

After deployment:

  • http://example.com redirects to https://example.com
  • Certificates renew automatically before expiration
  • Certificate data persists in the traefik-letsencrypt Docker volume

DNS must be configured first

Let's Encrypt validates domain ownership via HTTP challenge. Your domain's A record must point to the server IP before requesting certificates.

Deployment Workflow

First Deployment

# 1. Create project with ingress
aegis init my-app --components ingress
cd my-app

# 2. Configure and test locally
uv sync && cp .env.example .env
make serve  # Verify everything works

# 3. Set up deployment
aegis deploy-init --host your-server-ip
aegis deploy-setup

# 4. Deploy
aegis deploy

Subsequent Deployments

# Make changes, then redeploy (auto-backup + health check)
aegis deploy

# Or skip rebuild for config-only changes
aegis deploy --no-build

Backup and Rollback

Every aegis deploy automatically creates a backup before making changes. If the health check fails after deploy, the previous version is restored automatically.

# Create a manual backup
aegis deploy-backup

# List available backups
aegis deploy-backups

# Rollback to the most recent backup
aegis deploy-rollback

# Rollback to a specific backup
aegis deploy-rollback --backup 2026-03-11_183045

How backups work:

  • Backups are stored on the server at {deploy_path}/backups/{timestamp}/
  • Each backup contains a full snapshot of deployed files
  • PostgreSQL databases are dumped via pg_dump (SQLite files are included automatically)
  • Old backups are pruned automatically (default: keep last 5)
  • Backups are never synced or overwritten during deploys

Auto-rollback flow:

aegis deploy
  → backup current state
  → sync new code
  → docker compose up
  → health check (GET /health/)
    → pass: done
    → fail: restore backup automatically

Monitoring

# Check service health
aegis deploy-status

# Follow logs in real-time
aegis deploy-logs

# Check a specific service
aegis deploy-logs --service webserver

# Debug inside a container
aegis deploy-shell
