Test

Amazon S3 provides 2 modes to access S3 buckets and objects there:

• Path-style access: https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html#path-style-access
• Virtual-hosted-style access: https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html#virtual-hosted-style-access

Run the following to setup http routing, compile wasm and run envoy locally:

export http_proxy=http://localhost:8080
tinygo build -o main.wasm -scheduler=none -target=wasi main.go
func-e run -c envoy.yaml

Tests

• Virtual-hosted-style access: Should allow access:

curl  -I amzn-s3-demo-bucket1.s3.us-west-2.amazonaws.com

Should block access:

curl  -I amzn-s3-demo-bucket2.s3.us-west-2.amazonaws.com

• Path-style access: Should allow access:

curl  -I s3.us-west-2.amazonaws.com/amzn-s3-demo-bucket1

Should block access:

curl  -I s3.us-west-2.amazonaws.com/amzn-s3-demo-bucket2
