Creating Servers via REST API on RDO Mitaka via Chrome Advanced REST Client

In posting bellow we are going to demonstrate Chrome Advanced REST Client successfully issuing REST API POST requests for creating RDO Mitaka Servers (VMs) as well as getting information about servers via GET requests. All required HTTP Headers are configured in GUI environment as well as body request field for servers creation.

Version of keystone API installed v2.0

Following [ 1 ] to authenticate access to OpenStack Services, you are supposed first of all to issue an authentication request to get authentication token. If the request succeeds, the server returns an authentication token.

Source keystonerc_demo on Controller or on Compute node. It doesn’t
matter. Then run this cURL command to request a token:

curl -s -X POST \
-H “Content-Type: application/json” \
-d ‘{“auth”: {“tenantName”: “‘”$OS_TENANT_NAME”‘”, “passwordCredentials”: {“username”: “‘”$OS_USERNAME”‘”, “password”: “‘”$OS_PASSWORD”‘”}}}’ \
| python -m json.tool

to get authentication token and scroll down to the bottom :-

“token”: {
“audit_ids”: [
“expires”: “2016-04-21T18:26:28Z”,
“id”: “0cfb3ec7a10c4f549a3dc138cf8a270a”, <== X-Auth-Token
“issued_at”: “2016-04-21T17:26:28.246724Z”,
“tenant”: {
“description”: “default tenant”,
“enabled”: true,
“id”: “1578b57cfd8d43278098c5266f64e49f”, <=== Demo tenant’s id
“name”: “demo”
“user”: {
“id”: “8e1e992eee474c3ab7a08ffde678e35b”,
“name”: “demo”,
“roles”: [
“name”: “heat_stack_owner”
“name”: “_member_”
“roles_links”: [],
“username”: “demo”

Original request to obtain token might be issued via Chrome Advanced REST Client as well

Scrolling down shows up token been returned and demo’s tenant id

Required output





issued_at“: 2016-04-21T21:56:52.668252Z
expires“: 2016-04-21T22:56:52Z
id“: dd119ea14e97416b834ca72aab7f8b5a


description“: default tenant
enabled“: true
id“: 1578b57cfd8d43278098c5266f64e49f
name“: demo

Next create ssh-keypair via CLI or dashboard for particular tenant :-
nova keypair-add oskeymitaka0417 > oskeymitaka0417.pem
chmod 600 *.pem

Following bellow is a couple of samples REST API POST requests starting servers as they usually are issued and described.

curl -g -i -X POST -H “User-Agent: python-novaclient” -H “Content-Type: application/json” -H “Accept: application/json” -H “X-Auth-Token: 0cfb3ec7a10c4f549a3dc138cf8a270a” -d ‘{“server”: {“name”: “CirrOSDevs03”, “key_name” : “oskeymitaka0417”, “imageRef”: “2e148cd0-7dac-49a7-8a79-2efddbd83852”, “flavorRef”: “1”, “max_count”: 1, “min_count”: 1, “networks”: [{“uuid”: “e7c90970-c304-4f51-9d65-4be42318487c”}], “security_groups”: [{“name”: “default”}]}}’

curl -g -i -X POST http://192.169.142. 54:8774/v2/1578b57cfd8d43278098c5266f64e49f/servers -H “User-Agent: python-novaclient” -H “Content-Type: application/json” -H “Accept: application/json” -H “X-Auth-Token: 0cfb3ec7a10c4f549a3dc138cf8a270a” -d ‘{“server”: {“name”: “VF23Devs03”, “key_name” : “oskeymitaka0417”, “imageRef”: “5b00b1a8-30d1-4e9d-bf7d-5f1abed5173b”, “flavorRef”: “2”, “max_count”: 1, “min_count”: 1, “networks”: [{“uuid”: “e7c90970-c304-4f51-9d65-4be42318487c”}], “security_groups”: [{“name”: “default”}]}}’

We are going to initiate REST API POST requests creating servers been
issued  via Chrome Advanced REST Client

[root@ip-192-169-142-54 ~(keystone_demo)]# glance image-list

First required Headers were created in corresponding fields and
following fragment was placed in Raw Payload area of Chrome Client

{“name”: “VF23Devs03”,
“key_name” : “oskeymitaka0420”,
“imageRef” : “a050a122-a1dc-40d0-883f-25617e452d90“,
“flavorRef”: “2”,
“max_count”: 1,
“min_count”: 1,
“networks”: [{“uuid”: “292a2f21-70af-48ef-b100-c0639a8ffb22“}],
“security_groups”: [{“name”: “default”}]

Launching Fedora 23 Server :-

Next Ubuntu 15.10 Server (VM) will be created via changing  image-id in  Advanced RESTful Client GUI environment

Make sure that servers have been created and are currently up and running

Now launch Chrome REST Client again for servers verification via GET request
