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 3421
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-aws-xen-hvm-ubuntu-trusty-go_agent

# Upload specific version
$ bosh upload stemcell https://bosh.io/d/stemcells/bosh-aws-xen-hvm-ubuntu-trusty-go_agent?v=3421

Alternatively, download stemcell tarball locally:

# ...or download it directly using curl
$ curl -L -J -O https://bosh.io/d/stemcells/bosh-aws-xen-hvm-ubuntu-trusty-go_agent?v=3421

# or with wget...
