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.

Upload latest version to your BOSH Director:

# Upload latest version, currently 3312.26
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-aws-xen-ubuntu-trusty-go_agent

# Upload specific version
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-aws-xen-ubuntu-trusty-go_agent?v=3312.26

Alternatively, download stemcell tarball locally:

# ...or download it directly using curl
$ curl -L -J -O https://bosh.io/d/stemcells/bosh-aws-xen-ubuntu-trusty-go_agent?v=3312.26

# or with wget...
$ wget --content-disposition https://bosh.io/d/stemcells/bosh-aws-xen-ubuntu-trusty-go_agent?v=3312.26

      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

      Changes - 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 - Made ownership & permissions for /etc/cron* files more restrictive - Customize shell prompt to show instance name and ID - Removed floppy drives from vSphere stemcells - Removed bosh micro assets hence making bosh micro unsupported

      Misc: - Stemcells are now built through Concourse via https://main.bosh-ci.cf-app.com/teams/main/pipelines/bosh:stemcells
