⁠Dashboard Promote Runner

A small, transient task image used by the Infrastructure Management Dashboard⁠ to perform cross-cloud VM image promotion — converting a VM disk image and uploading it into a target cloud's storage so the cloud-native image-import API can consume it.

• Multi-arch: linux/amd64 + linux/arm64.
• Base: python:3.12-slim + qemu-img + the AWS/Azure/GCP SDKs (one image serves all three targets).
• It's the default for the dashboard's promote_runner_image setting; override it on the dashboard's Storage settings to pin a private or hardened build.

⁠What it does

Given a presigned source URL and a destination, the runner downloads the artefact, converts the disk format with qemu-img if needed, and uploads it to the target (S3 / Azure Blob / GCS), then exits. The dashboard handles every cloud-API call before and after — the runner's contract is simply download → convert → upload → exit zero. The source URL is presigned, so the container never sees source-side credentials.

⁠Invocation (reference)

The dashboard passes CLI arguments; destination credentials come from the task's IAM role or injected secure env vars:

python /entrypoint.py \
  --source-url <presigned-https-url> \
  --source-format vhd|raw|qcow2|vmdk \
  --target-format <format> \
  --target s3|azure|gcs \
  --dest-...    <target-specific flags>
