Yeah, we meant to make that be an optional configuration option, but looks like didn’t make it into 0.1. Feel free to open a GithHub PR/Issue or we we’ll get to it shortly too.
Following up on this - we merged a PR today that enables users to change the listening port for ECS. You can see that PR here if you are curious - PR 661.
Sorry again for missing this on the initial release. This capability will officially be included on the next release we cut. Stay tuned!
