This makes set up easier for new users. Users can still set
FISSION_NAMESPACE but it will default to "fission". Users can also
still set KUBECONFIG, but it will default to $HOME/.kube/config.
Also, update the post-install chart notes.txt and the install guide to
use "fission function test" as the first step after install. This
means that if there's anything wrong with the setup, the user will see
useful errors instead of "internal server error". Also, they can test
their setup without worrying about nodeports or ingresses or whatever.
All existing functionality of FISSION_URL and FISSION_ROUTER continues
to work.
This the very first step for fission to integrate with Istio, which is an open platform to connect, manage, and secure microservices. With Istio, users are able to monitor functions usage and trace requests latency through dashboards. For more information, please visit http://fission.io/docs/
Switch Fission's storage over to the new CustomResourceDefinitions, from the deprecated ThirdPartyResources. This allows us to be compatible with Kubernets 1.8 and onwards.
This also adds a CLI tool for dumping state from an old fission version and restoring state into new CRDs.
The storage service is unaffected by this change.
closes#319
* Make default node-env use alpine, and support separate debian env. List envs in documentation.
* Copy ONBUILD base image commands into node Dockerfiles
* Copy more commands from onbuild image
* Tidy dockerfiles
Allows dumping v0.1 state to a json file and restoring it into a new v0.2.1 fission installation.
Usage guide is at: /Documentation/docs-site/content/upgrade-from-v0.1.md
Adds support for message queue triggers based on the NATS-Streaming message queue.
This lets the user map a queue topic to a function, and optionally send the function's response into another queue topic.
The message queue trigger manager is designed to be message queue independent, so we should be able add support for more queues by adding implementations for the relatively simple mqtrigger.MessageQueue interface.
Add function log aggregation and persistence using Fluentd and InfluxDB.
Fluentd and a helper sidecar run as a daemonset. The poolmgr sets up logging for each function pod, using the helper sidecar. Fluentd forwards logs to InfluxDB, which is run as a deployment and service. The client CLI directly queries InfluxDB for logs.
Fluentd supports many outputs besides InfluxDB, so we aren't very tied to InfluxDB.
The setup is somewhat manual, which we should be able to improve by integrating this into the helm chart.
