Windows stemcells

A BOSH stemcell is a versioned OS image wrapped with IaaS specific packaging. BOSH uses a stemcell to supply the basic OS for any Windows VM it creates. A typical BOSH stemcell for Windows contains:

  • A bare minimum Windows OS skeleton
  • A BOSH agent
  • OS configuration files and common utilities

For more information about stemcells, see the BOSH documentation in the Cloud Foundry BOSH documentation.

Windows stemcell compatibility

Check the compatibility details before deploying and installing the TAS for VMs [Windows] tile. See Stemcells (Windows) on VMware Tanzu Network.

Depending on your IaaS, you can create or download a stemcell using the following methods:

    Offer                     Publisher    Sku    Urn                                                  Version
    ------------------------  -----------  -----  ---------------------------------------------------  -------------
    bosh-windows-server-2019  pivotal      2019   pivotal:bosh-windows-server-2019:2019:2019.1.050001  2019.1.050001
    bosh-windows-server-2019  pivotal      2019   pivotal:bosh-windows-server-2019:2019:2019.2.022001  2019.2.022001
    bosh-windows-server-2019  pivotal      2019   pivotal:bosh-windows-server-2019:2019:2019.3.041001  2019.3.041001
    bosh-windows-server-2019  pivotal      2019   pivotal:bosh-windows-server-2019:2019:2019.4.044001  2019.4.044001
    bosh-windows-server-2019  pivotal      2019   pivotal:bosh-windows-server-2019:2019:2019.5.006001  2019.5.006001
