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 2cc3e39f37f44a636f4a1957b5d55f6b230a5bc2 \ https://bosh.io/d/stemcells/bosh-vcloud-esxi-centos-7-go_agent?v=3763.7
And reference this stemcell in your deployment manifest from the
- alias: "default" os: "centos-7" version: "3763.7"
