@sealant/worker

Purpose

@sealant/worker is the background execution worker for sandbox image build jobs and runtime launch handoff.

It consumes queued build jobs, compiles/publishes artifacts, and updates durable lifecycle state.

Current capabilities

• RabbitMQ transport via @sealant/rabbitmq
• durable build/job state updates via @sealant/db
• BuildKit compile, registry publication, and runtime launch via @sealant/sandboxes
• source-provider resolution via @sealant/source-integrations

Key dependencies

• @sealant/db
• @sealant/rabbitmq
• @sealant/sandboxes
• @sealant/source-integrations

Environment highlights

Worker env combines database + RabbitMQ contracts with worker-specific defaults for:

• registry connectivity
• optional GitHub App credentials
• Docker socket path
• default runtime adapter
• default startup and SSH behavior for launched sandboxes
• worker identity and lease duration

See apps/worker/src/env.ts for the full contract.

Runtime scripts

• pnpm --filter @sealant/worker dev
