func ResolveHost ¶

func ResolveHost(ctx context.Context, port, override string) (host string, dnsOK bool)

ResolveHost returns the best host:port for reaching LocalStack on the given port. If override is non-empty it is returned as-is. Otherwise a DNS check is performed; if Hostname does not resolve to 127.0.0.1 (e.g. DNS rebind protection is active), it falls back to 127.0.0.1 directly.

func S3Addressing ¶ added in v0.13.0

func S3Addressing(endpointURL string) (pathStyle bool, s3Endpoint string)

S3Addressing decides S3 path-style and the S3 endpoint for the given base endpoint. Virtual-host-style addressing (used by *.localstack.cloud hosts) places the bucket as a subdomain of the S3 endpoint host, so the S3 endpoint host carries an `s3.` prefix and path style is off. Non-domain hosts (127.0.0.1/localhost) require path style and use the bare endpoint.

It is used both by the Terraform proxy (to set `s3_use_path_style` and the `s3` endpoint key in the generated override) and by the CDK proxy (to set `AWS_ENDPOINT_URL_S3`). CDK has no env-only lever for path style, so a pathStyle==true result there is informational only — see the cdk-proxy design.
