Cloudly owns orchestration and user-facing downloads. CoreBuild runs on suitable builder nodes, executes isocreator, uploads artifacts to S3-compatible storage, and returns artifact metadata to Cloudly.

Runtime

Required environment:

COREBUILD_PORT: HTTP port, defaults to 3060.
COREBUILD_TOKEN: shared worker token expected from Cloudly.
COREBUILD_WORKDIR: temp workspace, defaults to .nogit/workdir.
ISO_CREATOR_COMMAND: command used to run isocreator, defaults to isocreator.

For local development against the workspace checkout:

ISO_CREATOR_COMMAND="deno run --allow-all ../isocreator/mod.ts" pnpm run startTs

API

GET /health
GET /corebuild/v1/capabilities
POST /corebuild/v1/jobs/baseos-image

The BaseOS image job expects Cloudly to provide the S3 descriptor and a one-time provisioning token. CoreBuild never stores those values beyond the build workspace.
