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 a7fc5554e2bfb2e9e9a34c0dbbcc43c42381fa24 \ https://bosh.io/d/stemcells/bosh-softlayer-xen-ubuntu-xenial-go_agent?v=97.22
And reference this stemcell in your deployment manifest from the
- alias: "default" os: "ubuntu-xenial" version: "97.22"
