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 3312.15
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-azure-hyperv-ubuntu-trusty-go_agent

# Upload specific version
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-azure-hyperv-ubuntu-trusty-go_agent?v=3312.15

Alternatively, download stemcell tarball locally:

# ...or download it directly using curl
$ curl -L -J -O https://bosh.io/d/stemcells/bosh-azure-hyperv-ubuntu-trusty-go_agent?v=3312.15

      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
