Initializating Application

vela init

To initialize and deploy an application with one service, run:

If you only want to initialize without deploying the app, add --render-only flag

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

? Choose workload type for your service:  webservice
? What would you name this webservice:  testsvc
? specify app image crccheck/hello-world

Deploy Multiple Services

You can also use KubeVela CLI to deploy multiple services for an application.

Check the available workload types.

$ vela workloads
NAME      	DESCRIPTION
worker   	Backend worker without ports exposed
webservice	Long running service with network routes

Deploy the first service named frontend with Web Service type:

$ vela svc deploy frontend --app testapp -t webservice --image crccheck/hello-world
App testapp deployed

TODO auto generate a random application name, so --app testapp becomes optional

Deploy the second service named backend with "Backend Worker" type:

$ vela svc deploy backend --app testapp2 -t worker --image crccheck/hello-world
App testapp2 deployed

$ vela ls
SERVICE 	APP     	TYPE	TRAITS	STATUS 	CREATED-TIME
frontend	testapp 	    	      	...
backend 	testapp 	    	      	...
