Persistent Storage

Master the core principles and configuration of persistent storage in ClawCloud Run to ensure container data security and durability.

Why Persistent Storage Matters

ClawCloud Run allows rapid scaling and rebuilding of container instances, but data stored inside containers is ephemeral—it disappears when containers terminate. Persistent storage acts as a "safe deposit box" by:

• ✅ Securing data through external storage, even if containers restart, migrate, or rebuild.

• ✅ Enabling flexible scaling with dynamically adjustable storage capacity.

When to Use Persistent Storage

• File storage services (Nextcloud, ownCloud, etc.)

• User session data

• Long-term log retention

• Any application requiring persistent business data

Nextcloud Deployment Example

For a Nextcloud cloud storage service, critical data resides in the container’s /var/www/html directory, including:

• User configurations (config/)

• Database files (data/)

• Uploaded files (files/)

• Plugins (apps/)

Configuring Persistent Storage

1. Mount External Storage: Link the container’s data directory to secure external storage.

Persistent Storage Configuration

1. Key Settings:

• Container Path: Specify /var/www/html for Nextcloud.

• Storage Size: Adjust based on business needs (e.g., 100GB).

How It Works

• Zero Downtime: If a Nextcloud instance fails, a new container automatically mounts the same external storage, preserving all data.

• Cross-Instance Consistency: All instances access the same centralized data source.
