A stemcell is a versioned Operating System image wrapped with IaaS specific packaging.

Typical stemcell contains bare minimum OS skeleton with few common utilities pre-installed, a BOSH Agent and few configuration files to make OS be securely configured by default.

Ubuntu Lucid, CentOS 6.x, and Ruby agent based stemcells are deprecated.

      Reported Problems

      • bosh-init doesn’t work with this stemcell on OpenStack and AWS due to https://github.com/cloudfoundry/bosh/issues/1500
      • Booting the stemcell image directly in you IaaS (without using BOSH/bosh-init) does no longer provision the ssh key for user vcap, so you need to login differently
