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.
|
|

`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.

`/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`
|
|
|

## 🛠️ 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;"
|
|
``` |
