Learn how to connect to Milvus databases in Sealos DevBox using Go
This guide will walk you through the process of connecting to a Milvus database using Go within your Sealos DevBox project.
Prerequisites
- A Sealos DevBox project with Go environment
- A Milvus database created using the Database app in Sealos
Install Required Packages
In your Cursor terminal, install the necessary packages:
These commands install the Milvus Go SDK and the godotenv package for loading environment variables.
Connection Setup
Set up the environment variables
Create a .env
file in your project root with the following content:
Replace the placeholders with your actual Milvus credentials and desired configuration.
Create the main.go file
Create a new file named main.go
with the following content:
This code demonstrates how to connect to Milvus, create a collection, list collections, show and create partitions, and clean up by dropping the collection.
Usage
To run the application, use the following command in your Cursor terminal:
This will execute the main
function, demonstrating the connection to Milvus and basic operations with collections and partitions.
Best Practices
- Use environment variables for Milvus connection details and configuration.
- Always handle potential errors using proper error checking.
- Use contexts with timeouts for operations to prevent hanging in case of network issues.
- Close the Milvus client connection after operations are complete.
- Clean up resources (like dropping test collections) after you're done with them.
Troubleshooting
If you encounter connection issues:
- Verify your Milvus credentials in the
.env
file. - Ensure your Milvus database is running and accessible.
- Check for any network restrictions in your DevBox environment.
- Confirm that the required packages are correctly installed.
