This BOSH release is an attempt to get a more customizable/secure haproxy release than what is provided in cf-release. It allows users to blacklist internal-only domains, preventing potential Host header spoofing from allowing unauthorized access of internal APIs. It also allows for better control over haproxy's timeouts, for greater resiliency under heavy load.
To use this bosh release, first upload it to your bosh:
bosh upload release https://bosh.io/d/github.com/cloudfoundry-community/haproxy-boshrelease
To deploy it, you will need the repository that contains templates:
git clone https://github.com/cloudfoundry-community/haproxy-boshrelease.git
cd haproxy-boshrelease
git checkout latest
You can either use the templates + examples provided to merge this in with an existing CloudFoundry deployment, or create a new deployment using this command:
make_manifest <aws-ec2|warden> <comma-separated-list-of-router-servers> <additional_templates>
NOTE: make_manifest requires spruce v1.8.9 or newer.
# Example for bare bones bosh-lite haproxy release on warden

bosh deploy
# Example for using keepalive with haproxy on warden:
