AWS CloudWatch Proxy-Wasm

🚧 Experimental Project 🚧

AWS CloudWatch Proxy-Wasm (ACPW) sends the request metric to Amazon CloudWatch Metrics using Wasm module.

Usage (local)

1. Get AWS credential

ACPW sends metrics to CloudWatch Metrics. In order to do that, you need to get access key ID and secret access key. The following policy is minimal one to work this project.

            "Effect": "Allow",
            "Action": "cloudwatch:PutMetricData",
            "Resource": "*"
        }
    ]
}

2. Install TinyGo

https://tinygo.org/getting-started/install/

3. Build Wasm modules

$ make build-all

After executing the command above, please make sure the root directory has sender.wasm and receiver.wasm

4. Start project

$ export ACPW_AWS_ACCESS_KEY_ID=[access key ID you got step1]
$ export ACPW_AWS_SECRET_ACCESS_KEY=[secret access key you got step1]
$ docker-compose up

5. Test

➜ curl localhost:18000/test -H "Host: example.com"
