Connection error with Docker node:17-alpine

Running a basic consumer on node:17-alpine is causing errors when connecting to Confluent Cloud. **Dropping down to node:10-alpine solves the problem**

The same code, outside of docker, can connect to a confluent cloud instance
Inside the docker container with node:17-alpine, we receive the following:

```
LibrdKafkaError: Local: Broker transport failure
at Function.createLibrdkafkaError [as create] (/usr/local/app/node_modules/node-rdkafka/lib/error.js:454:10)
at /usr/local/app/node_modules/node-rdkafka/lib/client.js:350:28 {
origin: 'local',
message: 'broker transport failure',
code: -195,
errno: -195
}
Something went wrong:
Error: broker transport failure
```

An identical Dockerfile with node:10-alpine does not have the same issue
