Example to demonstrate the possibility of connecting Serverless Functions to MongoDB.
For this example, Scaleway Console will be used for deployment.
Warning
This is a basic sample that does not use a certificate for authentication, not recommended for production.
- MongoDB created documentation
- The MongoDB instance must be public (not listening to a private network only since Serverless Functions do not support private networks yet)
After MongoDB creation, in the console, find the public endpoint of the database; it should look like: <scw_database_id>.mgdb.<scw_region>.scw.cloud
Once you get the endpoint, keep it somewhere for later use.
Before creating the Function, we need to package it into a zip file.
Tip
It's recommended to do it via command line tools, so the following example shows how to zip this current folder:
cd ~/scaleway/serverless-examples/functions/go-mongo/
zip -r go-mongo.zip *- Create a Serverless Function namespace. Documentation
- In the created namespace, create a Serverless Function.
- Select the latest Go runtime.
- Upload the previously created
go-mongo.zip. - Ensure the handler is
Handle. - Add required Secrets to the Function:
| Key | Value |
|---|---|
| MONGO_PUBLIC_ENDPOINT | (replace with required values): <scw_database_id>.mgdb.<scw_region>.scw.cloud |
| MONGO_USER | user created during MongoDB setup |
| MONGO_PASSWORD | password created during MongoDB user setup |
Once your Serverless Function is in ready state, you can call it using the generated endpoint.
Result should be similar to:
{ "ID": 2911126, "Name": "RandomName2911126" }For testing, you can use Go Offline Testing.
To run locally, execute: go run cmd/main.go.
