It’s still on the docket, but I don’t know where it is. The backend for it exists, but I don’t think it’s hooked up to the API yet. It’ll happen! ---

You can put an app on a specific network-id (the org your app is on has a default network, but you can create others) with `flyctl apps create --network`. Apps on their own network won’t be able to talk to apps on other networks. There’s no current bridging you can do from one network to another; our private network enforcement is very simple (which is why we trust it). ---

I regret that I may have revealed its existence here, because I hate it. But it’s not going away (it’s useful with Fly Machines for large-scale multitenant stuff). ---

Why do you hate it? ---

How can this be done for when you’re creating an app via the machine Rest API? > [@thomas](#): > > You can put an app on a specific network-id (the org your app is on has a default network, but you can create others) with `flyctl apps create --network`. ---

You can pass a `network` param, there’s an example here: [Running user code on Fly Machines · Fly Docs](https://fly.io/docs/app-guides/functions-with-machines/#create-an-app) ---

Great to learn about custom private networks! Is there a way to limit the data transfer amount of a certain app? I feel like this would be useful for FaaS. ---

How do you specify a specific network ID for a Postgres Cluster? It is not provided as a mutation param in the GraphQL service. ---

I replaced the createPostgresCluster mutation with the createApp mutation followed by the createVolume mutation. This solves my issue. [Previous page](https://community.fly.io/t/multi-tenant-applications/375.md?page=1)
