Concepts of Fission architecture and components Environments. Environments are the language-specific parts of Fission. An Environment contains just enough software to build and run a Fission Function. Since Fission invokes Functions through HTTP, this means the runtime of an environment is a container with an HTTP server, and usually a dynamic loader that can load a function.FISSION WORKFLOWS
What you see is the YAML-based workflow definition of the fortunewhale workflow. A workflow consists of multiple tasks, which are steps that it needs to complete. Each task has a unique identifier, such as GenerateFortune, a reference to a Fission function in the run field. Optionally, it can contain inputs which allows you to specify inputs to the task, as well as contain requires which DECLARATIVE SPECIFICATIONS (SPEC) Your new updated function is deployed! Test it out by entering a * for the operator in the form!. Add dependencies to the function. Let’s say you’d like to add a pip dependency in requirements.txt to your function, and include some libraries in it, so you can import them in your functions. Add a library to the requirements.txt and modify the ArchiveUploadSpec inside specs/function-.yaml. ENVIRONMENTS (LANGUAGES) Environment Interface Version. Currently, Fission support three environment interface version: v1, v2 and v3. v1. Support loading function from a single file. (Mainly for interpreted languages like Python and JavaScript.) You are NOT allowed to specify which entrypoint to load in if there are multiple entrypoint in the file.OPENSHIFT | FISSION
OpenShift specific setup Installing Fission. See Fission installation to learn more how to install Fission.. Run Logger as privileged container. The reason to run Logger pods as privileged container is because Fission mounts hostPath volume to FluentBit to read container log files and data persistence.. The persistence is for FluentBit tail plugin to read/write it’s own sqlite database.TRIGGERS | FISSION
Functions are invoked on the occurrence of an event; a Trigger is what configures Fission to use that event to invoke a function. In other words, a trigger is a binding of events to function invocations. There are several types of triggers like HTTP trigger and message queuetrigger.

OPEN SOURCE, KUBERNETES-NATIVE SERVERLESS FRAMEWORKInstall Fission
WHAT IS FISSION?
FISSION IS A FRAMEWORK FOR SERVERLESS FUNCTIONS ON KUBERNETES. Write short-lived functions in any language, and map them to HTTP requests (or other event triggers). Deploy functions instantly with one command. There are no containers to build, and no Docker registries to manage. Learn More & Install FissionBENEFITS
FOCUS ON CODE, NOT PLUMBING Fission lets developers run code functions easily, while automating the menial work of configuring Kubernetes micro-services conceptsbehind the scenes.
Just write your code functions and Fission will make it run onKubernetes.
PORTABLE: RUN YOUR LAMBDA-LIKE SERVICE, ANYWHERE Fission is open source under the Apache license. Fission works on a Kubernetes cluster anywhere: on your laptop, in any public cloud, or in a private data-center. Write your application with the flexibility of deploying it anywhere. EXTENSIBLE AND CUSTOMIZABLE Fission is extensible to any programming language (Python, NodeJS, Go, C#, PHP are supported today). It abstracts away containers by default, but you can build your own containers if you need to.USE CASES
BUILD SERVERLESS API BACKENDS Create API backends for web and mobile apps without managing servers. Just write functions, and map them to HTTP routes. Fission takes care of the rest: deployment, routing, scalability, availability. Use Kubernetes’ service discovery and networking to interoperate with other services, like Redis, Postgres, Etcd etc. EASILY IMPLEMENT WEBHOOKS Webhooks are a popular way to integrate with third-party services. Slack provides webhooks that are triggered by certain words or messages; Github provides webhooks triggered by events in Git repositories. Fission is a great place to implement webhooks: just write the code, map it to a URL, and point the webhook at that URL. WRITE KUBERNETES EVENT HANDLERS By subscribing to Kubernetes watches, you can write custom automation for your Kubernetes infrastructure. Fission’s integration with Kubernetes watches allows you to monitor resources such as Pods and Services, and execute arbitrary functions when the watched set ofresources change.
