GeoNetwork

Introduction to GeoNetwork

GeoNetwork is an open-source cataloging tool designed to manage spatially referenced resources. It provides a robust platform for geospatial metadata management, enabling organizations to share, find, and use spatial data. Key features include:

• Metadata Management: Create, edit, and manage geospatial metadata.
• Data Discovery: Search and access spatial datasets via an intuitive interface.
• Interoperability: Supports OGC standards such as CSW, WMS, WFS, and WCS.
• Integration: Seamless integration with GIS platforms and web services.

GeoNetwork is widely used by governments, research institutions, and organizations that need to catalog and disseminate spatial data.

Deployment on Akash

Step 1: Prerequisites

1. Akash Account and Wallet: Ensure you have an Akash account and wallet set up with sufficient AKT tokens.
2. Akash CLI: Install and configure the Akash CLI tool on your machine.
3. GeoNetwork Docker Image: Use the official GeoNetwork Docker image from Docker Hub (geonetwork:latest).

Step 2: Create a Deployment SDL File

The SDL (Service Definition Language) file defines the deployment. Here’s a sample SDL file for GeoNetwork:

version: "2.0"

services:
  geonetwork:
    image: geonetwork:latest
    expose:
      - port: 8080
        as: 80
        to:
          - global
    env:
      - JAVA_OPTS=-Xms512m -Xmx1024m
    resources:
      cpu:
        units: 0.5
      memory:
        size: 1Gi
      storage:
        size: 5Gi

profiles:
  compute:
    geonetwork:
      resources:
        cpu:
          units: 0.5
        memory:
          size: 1Gi
        storage:
          size: 5Gi
  placement:
    global:
      attributes:
        region: us-west

deployment:
  geonetwork:
    geonetwork:
      profile: geonetwork
      count: 1

Explanation of the SDL File:

• Services Section: Specifies the GeoNetwork Docker image and exposes port 8080.
• Environment Variables: Configures the JVM options (JAVA_OPTS) for GeoNetwork.
• Resources: Allocates 0.5 CPU, 1 GiB of memory, and 5 GiB of storage.
• Placement: Specifies the preferred region for deployment.

Step 3: Deploy on Akash

1. Initialize Deployment: Use the Akash CLI to create and deploy the configuration:

   provider-services tx deployment create deploy.yaml --from <wallet_name>

2. View Deployment Status: Check the status of your deployment:

   provider-services query deployment list --owner <your_wallet_address>

3. Accept a Lease: Once your deployment is created, accept a provider’s lease:

   provider-services tx market lease create --dseq <deployment_sequence> --from <wallet_name>

Step 4: Access GeoNetwork

After the deployment is live, access GeoNetwork via the external IP provided by the Akash provider. You can use a browser to navigate to:

http://<external_ip>

Step 5: Configure GeoNetwork

1. Login: The default admin credentials are:
   • Username: admin
   • Password: admin
2. Start Cataloging:
   • Create new metadata records or upload existing ones.
   • Configure GeoNetwork to interact with your GIS or data storage solutions.

Step 6: Monitor and Update

• Logs: View logs to troubleshoot any issues:

  docker logs <container_id>

• Updates: To update GeoNetwork, redeploy with the latest Docker image.

Conclusion

Deploying GeoNetwork on Akash provides a decentralized, cost-efficient way to manage and share geospatial data. By leveraging Akash’s decentralized cloud, you can ensure scalability and resilience for your geospatial cataloging needs.
