+# NocoDB Module
+
+This module deploys [NocoDB](https://www.nocodb.com/), an open-source no-code database platform that transforms PostgreSQL into a smart spreadsheet interface, as Docker containers in the homelab environment.
+
+## Overview
+
+The NocoDB module:
+
+- Deploys two Docker containers:
+  - `nocodb`: The main NocoDB application server
+  - `nocodb-postgres`: A PostgreSQL database backend
+- Creates a dedicated Docker network (`nocodb-network`) for container communication
+- Persists data to volumes on the host
+- Provides service definition for integration with networking modules
+
+## Usage
+
+```hcl
+module "nocodb" {
+  source           = "./modules/20-services-apps/nocodb"
+  volume_path      = "/path/to/volumes"
+  networks         = ["homelab-network"]
+  postgres_user    = "postgres"
+  postgres_password = "your_secure_password"
+  postgres_db      = "root_db"
+}
+```
+
+## Variables
+
+| Variable            | Description                                                    | Type           | Default                |
+| ------------------- | -------------------------------------------------------------- | -------------- | ---------------------- |
+| `image_tag`         | Tag of the NocoDB image to use                                 | `string`       | `"latest"`             |
+| `postgres_image_tag`| Tag of the PostgreSQL image to use                             | `string`       | `"16.6"`               |
+| `volume_path`       | Host path for NocoDB and database data volumes                 | `string`       | -                      |
+| `networks`          | List of networks to which NocoDB should be attached            | `list(string)` | `[]`                   |
+
+## Outputs
+
+| Output               | Description                                                |
+| -------------------- | ---------------------------------------------------------- |
+| `service_definition` | Service definition for integration with networking modules |
+
+## Service Definition
+
+This module outputs a service definition that is used by the networking modules to expose the service.
+
+```hcl
+{
+  name         = "nocodb"
+  primary_port = 8080
+  endpoint     = "http://nocodb:8080"
+  subdomains   = ["nocodb"]
+  publish_via  = "tunnel"  # Only publish through Cloudflare tunnel
+}
+```
+
+## Environment Variables
+
+NocoDB requires several environment variables to function properly. These are stored in a `.env` file in the module directory and read using the `dotenv` Terraform provider:
+
+- Database configuration:
+
+  - `DB_USERNAME`: PostgreSQL user
+  - `DB_PASSWORD`: PostgreSQL password
+  - `DB_DATABASE`: Database name (defaults to "root_db")
+
+## Data Persistence
+
+NocoDB stores its data in two main volumes:
+
+1. NocoDB application data: `/usr/app/data` in the container, mapped to `${volume_path}/nocodb/data` on the host
+2. PostgreSQL data: `/var/lib/postgresql/data` in the container, mapped to `${volume_path}/nocodb/postgres/data` on the host
+
+## Networking
+
+The module creates a dedicated Docker network named `nocodb-network` for communication between the NocoDB components. The NocoDB server container is also attached to any additional networks specified in the `networks` variable, allowing it to communicate with other services in the homelab.
+
+## Dependencies
+
+The NocoDB container depends on PostgreSQL, which includes a healthcheck to ensure it's ready before NocoDB starts.
+
+## Integration with Networking Modules
+
+This service is configured to be exposed through a Cloudflare tunnel for secure remote access, set by `publish_via = "tunnel"`.
+
+## Example Integration in Main Configuration
+
+```hcl
+module "nocodb" {
+  source           = "./modules/20-services-apps/nocodb"
+  volume_path      = module.system_globals.volume_host
+  networks         = [module.services.homelab_docker_network_name]
+  postgres_password = "your_secure_password"
+}
+
+# The service definition is automatically included in the services output
+module "services" {
+  source = "./modules/services"
+  # ...
+  service_definitions = [
+    module.nocodb.service_definition,
+    # Other service definitions
+  ]
+}
+```
