Running Hasura v3 locally without DDN login / in an air-gapped environment

[akashmandal861]

Hi everyone,

I’m trying to understand whether Hasura v3 can be deployed and used completely locally without logging into Hasura Cloud.

From what I see, the DDN CLI workflow seems to require authentication (ddn auth login), even for initializing a project and managing metadata. However, in some environments (for example air-gapped or restricted networks) internet access and external authentication may not be possible.

My questions are:

1. Is it possible to run Hasura v3 fully locally without logging into Hasura Cloud?
2. Can the DDN CLI be used without authentication, or is there an offline mode?
3. If authentication is mandatory, what is the recommended approach for air-gapped deployments of Hasura v3?
4. Is there documentation or guidance on self-hosting Hasura v3 in isolated environments?

Any clarification on the recommended approach for this scenario would be very helpful.

Thanks!

Hi @akashmandal861 ,

1. Yes
   2, 3. No. However, the DDN CLI is used in development. It is not required in production runtime.

After you ran the ddn supergraph build local command, the metadata is built to the engine/build folder. When deploying the stack in the self-host environment, you just need to mount those metadata files into the v3-engine container and run them with Docker Compose or Kubernetes. The engine and connectors don't connect to Hasura Cloud, and don't lock your production runtime in the air-gapped environment.

Dear @hgiasac ,

Thanks for the quick response.
So if I understand correctly , we need to run ddn auth login followed by ddn supergraph build local in a dev env with internet. And then deploy the stack in air-gapped environment.
Is my understanding correct?
What if I dont want to login to hasura cloud, if the first step itself. Is there an alternative for that?

Best Regards,

No, there isn't. The metadata build service is hosted on Hasura Cloud, so you can't build it without logging in.
