Fujitsu K5 IaaS API Example

Here’s a very quick example of how to consume the K5 IaaS platform through it’s APIs. This is a simple demo that details how to create a security group using API calls with python 2.7.

First of all we need to get a project scoped token to authenticate the user which is achieved with the following function :

# get a project scoped auth token
def get_scoped_token(uname,upassword,uproject,udomain):
    identityURL = 'https://identity.uk-1.cloud.global.fujitsu.com/v3/auth/tokens'
    response = requests.post(identityURL, 
                             headers={'Content-Type': 'application/json','Accept':'application/json'}, 
                             json={"auth":
                                    {"identity":
                                      {"methods":["password"],"password":
                                        {"user":
                                           {"domain":
                                              {"name":udomain}, "name":uname, "password": upassword}}}, 
                                              "scope": { "project": {"id":uproject}}}})
    return response.headers['X-Subject-Token']

 

The token returned in the header of the previous API call is used in all subsequent API calls – k5token.

We can see below that currently we only have the default security group in this project :

sgbefore

The next function invokes the security group creation API call:

# create security group
def create_security_group(k5token,sgname,sgdescription):
    sgURL = 'https://networking.uk-1.cloud.global.fujitsu.com/v2.0/security-groups'
    response = requests.post(sgURL,
                            headers={'X-Auth-Token':k5token,'Content-Type': 'application/json','Accept':'application/json'},
                            json={"security_group":
                                   {"name": sgname,
                                    "description": sgdescription
                                   }
                                 })
    return response.json()

 

Which when called with the appropriate parameters results in the creation of a security group…surprise, surprise…

sgafter

But there’s no inbound (ingress) rules…

rules_before

Now all that’s needed is the rules that are to be applied to the security group. In this example I allow ssh access inbound with the following function :

def create_security_group_rule(k5token,direction,pmin,pmax,protocol,sgid):
    sgURL = 'https://networking.uk-1.cloud.global.fujitsu.com/v2.0/security-group-rules'
    response = requests.post(sgURL,
                            headers={'X-Auth-Token':k5token,'Content-Type': 'application/json','Accept':'application/json'},
                            json={"security_group_rule": 
                                   {"direction": direction,
                                    "port_range_min": pmin,
                                    "ethertype": "IPv4",
                                    "port_range_max": pmax,
                                    "protocol": protocol,
                                    "security_group_id": sgid
                                    }
                                  })
    return response.json()

 

Which when called with the correct parameters will result in:

rules_after

Finally we can list all the security group details with this function:

def list_security_groups(k5token):
    sgURL = 'https://networking.uk-1.cloud.global.fujitsu.com/v2.0/security-groups'
    response = requests.get(sgURL,
                            headers={'X-Auth-Token':k5token,'Content-Type': 'application/json','Accept':'application/json'})
    return response.json()

 

Putting it all together we get this script :

This script produces the following output:

Token : 623310d961db4a30a8b8b3410277a951
