Getting Started with KubeVela

KubeVela is a more enjoyable, app-centric, fully self-service tool for shipping applications to your Kubernetes clusters. KubeVela makes deploying applications to Kubernetes much easier. KubeVela is an open source tool that abstracts away the complicated Kubernetes artifacts from developers.

Quick Start

Welcome to KubeVela! In this guide, we’ll walk you through how to install KubeVela, and deploy your first simple application.

Step 1: Install

Make sure you have finished and verified the installation following this guide.

Step 2: Deploy Your First Application

$ kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/docs/examples/vela-app.yaml
application.core.oam.dev/first-vela-app created

Check the status until we see status  is running  and services are healthy :

$  kubectl get application first-vela-app -o yaml
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  generation: 1
  name: first-vela-app
  ...
  namespace: default
spec:
  components:
  - name: express-server
    type: webservice
    properties:
      image: crccheck/hello-world
      port: 8000
    traits:
    - type: ingress
      properties:
        domain: testsvc.example.com
        http:
          /: 8000
status:
  ...
  services:
  - healthy: true
    name: express-server
    traits:
    - healthy: true
      message: 'Visiting URL: testsvc.example.com, IP: your ip address'
      type: ingress
  status: running

Under the neath, the K8s resources was created:

$ kubectl get deployment
NAME                READY   UP-TO-DATE   AVAILABLE   AGE
express-server-v1   1/1     1            1           8m
$ kubectl get svc
NAME             TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
express-server   ClusterIP   172.21.11.152   <none>        8000/TCP   7m43s
kubernetes       ClusterIP   172.21.0.1      <none>        443/TCP    116d
$ kubectl get ingress
NAME             CLASS    HOSTS                 ADDRESS          PORTS   AGE
express-server   <none>   testsvc.example.com   <your ip address>   80      7m47s

If your cluster has a working ingress, you can visit the service.

$ curl -H "Host:testsvc.example.com" http://<your ip address>/
<xmp>
Hello World

                                       ##         .
                                 ### ### ##        ==
                              ### ### ### ### ##    ===
                           /""""""""""""""""\___/ ===
                      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
                           \______ o          _,/
                            \      \       _,'
                             `'--.._\..--''
</xmp>

Voila! You are all set to go.
