Yipee - Graphical Kubernetes Editing

Working with Kubernetes doesn't necessarily imply spending quality time with YAML. For the last couple of years, Yipee.io has provided SaaS-based graphical Kubernetes modeling at https://app.yipee.io and many people have taken advantage of this to avoid "YAML Hell". Throughout the development of the SaaS application, however, we heard from a sizeable segment of our users that they would like to have an on-premise, preferably open source, version of our tool. Well, here it is...

What does it do?

This repository contains the pure Kubernetes editing functionality from the original Yipee.io application but drops the SaaS-related parts. So, there are no teams, no model storage, and no authentication or authorization. Instead, you can simply point the application at a YAML file and edit your model graphically before saving it back out.

What does a model look like?

Here is a simple Joomla model:

It should be easy to understand the big picture.

The YAML for this model is:

apiVersion: v1
kind: Service
metadata:
  name: joomla
spec:
  selector:
    name: joomla-kubernetes
    component: joomla

What about Docker Compose?

The editor can import Docker Compose files. They will be turned into Kubernetes models on import. There is no support for going in the other direction. The Compose support is provided to help in migrating to Kubernetes.

Where do we go from here?

That's partly up to you! Yipee is open source now and we welcome collaborators and contributors. If you have an idea or opinion as to future directions, we're listening.

Installation

Yipee is ready to run as a kubernetes application. Public images built from the master branch of this repo are available in dockerhub. The yipee.yaml file in this repo defines the kubernetes objects needed to deploy the app. The full version of yipee will read the kubernetes cluster and allow modification and update of deployed applications. You can also import yaml files, make modifications in the editor and deploy the results to your cluster.

To run yipee in a local minikube, simply:

kubectl apply -f yipee.yaml
minikube -n yipee service yipee-ui

To run just the yipee editor (without support for reading from or deploying to kubernetes), do this instead:

kubectl apply -f editor.yaml
minikube -n yipeeed service yipee-ui

To deploy in a cloud-based cluster, you will want to change the type of the yipee-ui service definition from NodePort to LoadBalancer (or create an ingress).

Build from Source

Prerequisites

docker
bash
Building Images

You can build images from source by running build.sh at the top of the repo. By default this will produce three images:
yipee-converter
yipee-api
yipee-ui

Run with Locally Built Images

push the images to your kubernetes cluster
modify yipee.yaml to reference those images
apply the modified yipee.yaml

Integration with other tools

We've exposed an API that allows you to post your YAML file then open the browser with that file loaded. This is to aid integration with things like kubectl edit

API

URL: /api/import?store=true Content-Type: application/json
Payload: Json object with a name:string and importFile:base64 encoded YAML
Return: Json object success:boolean, total:int, data:[{name:string, guid:string}]

Take the guid returned from the import and open your browser to /editor/

Example

file import_test.json
{"name":"test_import", "importFile":"IyBHZW5lcmF0ZWQg...=="}

curl -v -d @import_test.json "http://35.193.60.29:8080/api/import?store=true" -H "Content-Type: application/json"

{"success":true,"total":1,"data":[{"name":"test_import","guid":"659a74c2-310b-4d48-a0e3-cd45fd7c6e7c"}]}

open http://35.193.60.29:8080/editor/659a74c2-310b-4d48-a0e3-cd45fd7c6e7c
