Antifreeze

Cloud Foundry CLI plugin to detect if an app has unexpected ENV vars or services bound which are missing from the manifest. Eliminate the snowflake!

Doubleplusgood with Autopilot, a CF CLI plugin for zero downtime application deploys, which demands an up-to-date manifest file.

Installation

Download the latest release and place the binary on your path, e.g. /usr/local/bin/antifreeze. Then run:

cf install-plugin /usr/local/bin/antifreeze

Or if you have go installed:

go get -u github.com/odlp/antifreeze
cf install-plugin $GOPATH/bin/antifreeze

Usage

cf check-manifest your-app-name -f manifest.yml

When your app has unexpected ENV vars or services you'll see output like this:

Running check-manifest...

App 'your-app-name' has unexpected ENV vars (missing from manifest ./manifest.yml):
- SNOW_FLAKE_VAR

App 'your-app-name' has unexpected services (missing from manifest ./manifest.yml):
- surprise-service

And the check-manifest command will exit with a non-zero status.

Example with Autopilot

Your deployment script could include:

#!/bin/bash

set -e

cf check-manifest your-app-name -f manifest.yml
cf zero-downtime-push your-app-name -f manifest.yml

Development

Clone the project & run the following:

./scripts/setup

Then you can run tests:

./scripts/test

And build & install locally to give any changes a spin:

./scripts/install-local
