BOSH release for the distributed storage system Ceph. It uses bosh export-release to package Ceph for offline running.
Ceph is mostly distributed via apt packages with a deep dependency tree. This makes it hard to write a packaging script that can "compile" the software in a way that allows it to be run offline without running apt install.
The solution used in this release is to download all the entire dependency graph of ceph as a set of debian packages and provide a script to install them in the right order. This allows the release to be compiled online where it can reach the correct apt repos.
To build this release for for offline environments, it needs to be compiled by deploying it to a BOSH director and then running bosh export-release for a specific stemcell. An example manifest can be found in ci/files/compile.yml.
bosh create-release
bosh upload-release
bosh deploy -d compiling-ceph ci/files/compile.yml
bosh export-release ceph/<version> ubuntu-xenial/<stemcell-version>
This will output a tarball - ceph-<version>-ubuntu-xenial-<stemcell-version>-XXXXXXXX-XXXXXX-XXXXXX.tgz which will contain all the relevant tarballs and a script to install them for offline use. The jobs then install Ceph in pre-start using:
pushd /var/vcap/packages/ceph
dpkg -l ceph || ./install_ceph.sh
popd
