go_serverless
test project for serverless go stack (aws)
Description
set-up similar to what is described in https://www.softkraft.co/aws-lambda-in-golang/ and in this tutorial.
More details and generic documentation can be found in AWS's docs, although that is referencing a HTTP API.
This is basically a CRUD API with Lambda and DynamoDB ___________________________________________________________ | AWS | _________ | __________ ________________________ __________ | The set-up is basically | clients | -> | | REST API | -> | Golang Lamda Function | -> | DynamoDB | | || | || |_______________________| |_________| | |___________________________________________________________|
The golang (amd64 arch) build needs to be uploaded to the Lambda function and then one needs to set-up Dynamo DB with the name go_serverless or whatever value is specified in main.go by the tableName const.
The Lamda function needs to have the Simple microservice permission policy applied to it.
Then the Amazon API Gateway (REST) needs to be set-up. The result of the set-up will be a URL value that is usable by external clients to hit the Lamda function (https://ssh***********c.execute-api.eu-central-1.amazonaws.com/vlad in my case)
One can then test if this all worked with the following curl commands:
- Add new User:
curl --header "Content-Type: application/json" --request POST --data '{"email": "some.user@client.com", "firstName": "Some", "lastName": "User"}' https://ssh***********c..execute-api.eu-central-1.amazonaws.com/vlad
- GET all users
curl -X GET https://ssh***********c..execute-api.eu-central-1.amazonaws.com/vlad
- Get a single user by email
curl -X GET https://ssh***********c..execute-api.eu-central-1.amazonaws.com/vlad?email=some.user@client.com
- Update User
curl --header "Content-Type: application/json" --request PUT --data '{"email": "some.user@client.com", "firstName": "Other", "lastName": "User"}' https://ssh***********c..execute-api.eu-central-1.amazonaws.com/vlad
- Delete a user
curl -X DELETE https://ssh***********c..execute-api.eu-central-1.amazonaws.com/vlad?email=some.user@client.com
