v0.5.0

Summary of changes introduced in v0.5.0:

• Breaking change: Functions have a new standard interface! It is required to adapt existing functions to the new format. Check out more info about the new interface and examples.
• Kubeless now supports PHP functions. Thanks to @paolomainardi! You can check PHP examples here.
• Alpha feature: It is now possible to generate redistributable Docker images with Kubeless functions. Check out how to do it here.
• Kafka and Zookeeper are now optional. If you want to use Kafka for triggering functions using the PubSub method follow the instructions below.
• Breaking change: Kubeless fully support Kubernetes 1.9. The support for 1.7 is now limited. Check the compatibility matrix to know more about features and versions supported.
• Breaking change: Function Triggers have now their own Custom Resources. The same function can now be triggered from several event sources using a single Function deployment. That means that it is required to create a specific Custom Resource to trigger functions using Kafka messages or with a scheduled cron task. There are new commands available to do so, check kubeless trigger --help to discover these commands. Architecture details can be found here.
• Breaking change: The flag --trigger-http has been removed from the kubeless function deploy command since every function will now expose a cluster-internal HTTP endpoint.
• Breaking change: The command kubeless route has been replaced with kubeless trigger http. This will create a new Ingress rule to expose a function outside the cluster. You can now also specify a path to deploy your function. More info here
