The release requires the Ruby gem Bundler (used by the vendoring script):
gem install bundler
With bundler installed, switch to ./src/bosh_azure_cpi and run the vendoring script:
./vendor_gems
If you are using Ubuntu 14.04, you should replace the bundle in ./vendor_gems with /usr/local/bin/bundle.
Then create the BOSH release:
bosh create release --force --with-tarball --name bosh-azure-cpi
The release is now ready for use. If everything works, commit the changes including the updated gems.
At the end of the CLI output there will be "Release tarball" path.
