VelaUX OpenAPI

This section will introduce how to integrate VelaUX OpenAPI, please make sure you have enabled the velaux addon. Let’s use port-forward to expose the endpoint for the following demo.

  1. vela port-forward addon-velaux -n vela-system 8000:80

Authentication and API Example

Login and get the token

VelaUX has introduced Json Web Token for authorization. As a result, you need to call the login API to complete the authentication and get the token. The following example is with the default admin account.

  1. curl -H Content-Type:application/json -X POST -d '{"username": "admin", "password":"VelaUX12345"}' http://127.0.0.1:8000/api/v1/auth/login

http://127.0.0.1:8000 This is demo address, you should replace it with the real address. If you changed the password, replace it with the real password.

The expected output should be like this:

  1. {
  2.  "user": {
  3.   "createTime": "0001-01-01T00:00:00Z",
  4.   "lastLoginTime": "0001-01-01T00:00:00Z",
  5.   "name": "admin",
  6.   "email": "barnett.zqg@gmail.com",
  7.   "disabled": false
  8.  },
  9.  "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZ3JhbnRUeXBlIjoiYWNjZXNzIiwiZXhwIjoxNjU2NTE0ODcyLCJpc3MiOiJ2ZWxhLWlzc3VlciIsIm5iZiI6MTY1NjUxMTI3Mn0.IqRWglW5cYMn8KJcbkoG55os9g-YTo_9UWFvbpZBKiY",

  11. }
  • accessToken: This is the token to request other APIs, which will expire in an hour.
  • refreshToken: This is the token to refresh the access token.

Request other APIs

  • Create an application
  1. curl -H Content-Type:application/json -H "Authorization: Bearer <accessToken>" -X POST -d '{"name":"first-vela-app", "project": "default", "alias": "Demo App", "envBinding": [{"name": "default"}], "component": {"name":"express-server","componentType":"webservice", "properties": "{\"image\":\"oamdev/hello-world\"}"}}' http://127.0.0.1:8000/api/v1/applications

Please replace <accessToken> with the response from the previous step.

The expected output should be like this:

  1. {
  2.  "name": "first-vela-app",
  3.  "alias": "Demo App",
  4.  "project": {
  5.   "name": "default",
  6.   "alias": "Default",
  7.   "description": "Default project is created by velaux system automatically.",
