Satellite

Unlike Skylab, the image junobuild/satellite runs a single Satellite in a headless environment, without the Console UI. It always mounts the same Satellite, using the fixed ID jx5yt-yyaaa-aaaal-abzbq-cai.

Configuration

To use this image, your configuration must include the satellite field in the emulator section.

Make also sure to set the runner type to match your container runtime, and define the static Satellite ID expected by the image.

juno.config.ts
import { defineConfig } from "@junobuild/config";

export default defineConfig({
  satellite: {
    ids: {
      development: "jx5yt-yyaaa-aaaal-abzbq-cai",
      production: "<PROD_SATELLITE_ID>"
    },
    source: "dist",
    predeploy: ["npm run build"]
  },
  emulator: {
    runner: {
      type: "docker"
    },
    satellite: {}
  }
});

For more advanced options like customizing ports, image name, or CI setup, see the Emulator Configuration section.
