BOSH produces official stemcells for popular operating systems and infrastructures. For infrastructures that support it, light stemcells are a more efficient way to reference stemcells that we have pre-uploaded and shared within the IaaS.
You can upload the latest version to your director with the
bosh upload-stemcell --sha1 39f34d1f22b084adacef351a5d03a8b38b258e64 \ https://bosh.io/d/stemcells/bosh-azure-hyperv-windows1803-go_agent?v=1803.4
And reference this stemcell in your deployment manifest from the
- alias: "default" os: "windows1803" version: "1803.4"
Windows instance types will have additional costs associated with Microsoft licensing. Windows stemcell do not include actual Windows OS.
