Talemu is Talos Emulator

Runs multiple fake Talos nodes at the same time. To be used in pair with Omni.

Running Emulator Static Mode

Do Copy Kernel Args in the Omni UI.

Create hack/compose/docker-compose.override.yml and paste copied kernel args there.

Final YAML file can look like this:

version: '3.8'
services:
  talemu:
    command: >-
      args:
        - --kernel-args="siderolink.api=grpc://192.168.88.219:8090?jointoken=w7uVuW3zbVKIYQuzEcyetAHeYMeo5q2L9RvkAVfCfSCD talos.events.sink=[fdae:41e4:649b:9303::1]:8090 talos.logging.kernel=tcp://[fdae:41e4:649b:9303::1]:8092"
        - --machines=100

Run make docker-compose-up command.

This will spawn one hundred fake Talos nodes.

Infra Provider Mode

Run:

make infra-provider

Then run:

sudo -E _out/talemu-infra-provider-linux-amd64 --create-service-account --omni-api-endpoint=https://localhost:8099

Create a machine request using omnictl:

metadata:
    namespace: infra-provider
    type: MachineRequests.omni.sidero.dev
    id: machine-1
    labels:
      omni.sidero.dev/infra-provider-id: talemu
spec:
  talosversion: v1.7.5
  schematicid: 376567988ad370138ad8b2698212367b8edcb69b5fd68c80be1f2ec7d603b4ba

The machine should be created by the emulator and appear in Omni.
