Quick Start

Welcome to KubeVela! In this guide, we'll walk you through how to deploy applications on KubeVela CLI/Appfile.

Setup

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

1. Initialize Application Deployment Config

$ vela init --render-only
Welcome to use KubeVela CLI! We're going to help you run applications through a couple of questions.

Environment: default, namespace: default

? What is the domain of your application service (optional):  example.com
? What is your email (optional, used to generate certification):
? What would you like to name your application (required):  testapp
? Choose the workload type for your application (required, e.g., webservice):  webservice
? What would you like to name this webservice (required):  testsvc
? specify app image crccheck/hello-world
? specify port for container 8000

Deployment config is rendered and written to vela.yaml

In current directory, you will have a generated vela.yaml:

createTime: ...
updateTime: ...

name: testapp
services:
  testsvc:
    type: webservice
    image: crccheck/hello-world
    port: 8000
    route:
      domain: testsvc.example.com

2. Deploy Application

$ vela up
Parsing vela.yaml ...
Loading templates ...

Rendering configs for service (testsvc)...
Writing deploy config to (.vela/deploy.yaml)

Applying deploy configs ...
Checking if app has been deployed...
App has not been deployed, creating a new deployment...
✅ App has been deployed 🚀🚀🚀
    Port forward: vela port-forward testapp
             SSH: vela exec testapp
         Logging: vela logs testapp
      App status: vela status testapp
  Service status: vela status testapp --svc testsvc

Check the status until we see route trait ready:

$ vela status testapp
About:

  Name:      	testapp
  Namespace: 	default
  Created at:	...
  Updated at:	...

Services:

  - Name: testsvc
    Type: webservice
    HEALTHY Ready: 1/1
    Last Deployment:
      Created at: ...
      Updated at: ...
    Routes:
      - route: 	Visiting URL: http://testsvc.example.com	IP: localhost

In kind cluster setup, you can visit the service via localhost:

If not in kind cluster, replace localhost with ingress address

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


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