To update memory size

The following update-service example updates the memory size of instances (scaling units) of an App Runner service to 2048 MiB.

When the call succeeds, App Runner starts an asynchronous update process. The Service structure that's returned by the call reflects the new memory value that's being applied by this call.

aws apprunner update-service \
    --cli-input-json file://input.json

    "InstanceConfiguration": {
        "Memory": "4 GB"

}

Output:
