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


      • Agent will now wait for monit to complete stop all processes before carrying on
      • Added google stemcells
      • Default dmesg_restrict to 1
      • Disable all IPv6 configurations
      • Reenabled UDF kernel module for Azure
      • Increase root_maxkeys and maxkeys kernel configurations
      • Changed default hostname to bosh-stemcell instead of localhost to avoid boot problems on GCP
      • Lower TCP keepalive configuration by default
      • Mount /var/log directory to /var/vcap/data/root_log
      • Restrict Access to the su command
      • Add pam_cracklib requirements to common-password and password-auth
      • Enable auditing for processes that start prior to auditd
      • Set log rotation interval to 15 min in stemcell

      • Customize shell prompt to show instance name and ID
      • Removed floppy drives from vSphere stemcells
      • Removed bosh micro assets hence making bosh micro unsupported
