# ⚡ My Cloud Hub: Daily Cheat Sheet

## 🚀 Dashboard Updates
Run this after pushing changes from your local PC to Gitea.

# Using the alias we created
`updatedash`

# Or manually:
`cd /opt/docker/dashboard && ./update-dash.sh`

## 🐳 Docker Maintenance
Essential commands for managing your container stack.

# View all running containers and their health
`docker ps`

# Restart a specific service (e.g., memos)
`cd /opt/docker/memos && docker compose restart`

# View live logs for a service to troubleshoot
`docker compose logs -f [service_name]`

# Clean up unused images/volumes (Run this if disk gets full)
`docker system prune -a --volumes`

## 🐘 Database (Postgres) Operations
Quick commands for interacting with your Universal DB.

# Access the Postgres CLI as the superuser
`docker exec -it global_postgres psql -U postgres`
```sql
# SQL Commands (run these inside psql):
# \l                                  -- List all databases
# \du                                 -- List all users/roles
# SELECT datname, pg_size_pretty(pg_database_size(datname)) FROM pg_database;
```

## ☁️ Backup & Cloud Storage
Manual triggers and verification for your S3 backups.

# Run a manual backup immediately
`/opt/docker/backups/backup-homelab.sh`

# List files in your Linode Object Storage bucket
`rclone ls linode-s3:davisdre-backups-chicago`

# Check the backup log for errors
`tail -n 20 /opt/docker/backups/backup.log`

## 🖥️ System Health & Monitoring
Keep an eye on that 2GB RAM limit and swap space.

# The 'Gold Standard' for real-time monitoring
`htop`

# Check disk space usage
`df -h`

# Check swap utilization specifically
`swapon --show`

## 🛠️ Infrastructure SOP: Adding a New App
1. Update global-db/compose.yaml environment list.
2. Manually provision the DB on the live instance:
```bash
docker exec -it global_postgres psql -U postgres -c "CREATE DATABASE app_name;"
docker exec -it global_postgres psql -U postgres -c "CREATE USER app_name WITH PASSWORD 'my-custom-password';"
docker exec -it global_postgres psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE app_name TO app_name;"
docker exec -it global_postgres psql -U postgres -c "ALTER DATABASE app_name OWNER TO app_name;"
```
