Usage

NSXClient

The NSXClient is the class used to send requests to the NSX host and pass through credentials.

Import the following files.

To create an NSX object run the following code, with the correct params.

import (
    "github.com/sky-uk/gonsx"
)

nsxclient := gonsx.NewNSXClient(url, username, password, ignoreSSL, debug)

The params used:

• url: URL of NSX host

E.G. https://nsxhost.com

• username: NSX username
• password: NSX password
• ignoreSSL: bool on whether to ignore ssl (default false)
• debug: bool on whether to debug output (default false)

The client is also used run the api calls once you have created the resource object.

nsxclient.Do(my_resource_obj)

Virtual Wire(Logical Switch)

Virtual Wire resource. This resource will call the Virtual Wires api within NSX. Import the following class:

github.com/sky-uk/gonsx/api/virtualwire

Create:

 api := virtualwire.NewCreate(virtualWireCreateSpec, scopeID)
 nsxclient.Do(api)

Read:

api := virtualwire.NewGetAll(scopeID)
nsxclient.Do(api)
resp := api.GetResponse().FilterByName(virtualWireName)

Read single virtualwire:

api := virtualwire.NewGet(virtualwireID)
nsxclient.Do(api)
resp := api.GetResponse()

Update:

api := virtualwire.NewUpdate(name, desc, virtualwireID)
nsxclient.Do(api)

Delete:

api := virtualwire.NewDelete(virtualWireID)
nsxclient.Do(delete_api)

Edge Interface

Interface resource. This resource will call the interface api within NSX. Import the following class:

github.com/sky-uk/gonsx/api/edgeinterface

Create:

 api := edgeinterface.NewCreate(&edgeInterfaces, edgeId)
 nsxclient.Do(api)
 createdEdgeInterfaces := api.GetResponse()

Read:

api := edgeinterface.NewGet((edgeid, index)
nsxclient.Do(api)
edge := api.GetResponse()

Update:

api := edgeinterface.NewUpdate(edgeid, index, edge)
nsxclient.Do(api)

Delete:

api := edgeinterface.NewDelete(edgeid, index)
nsxclient.Do(api)

Dhcp Relay

DHCP resource. This resource will call the DHCP relay api within NSX. Import the following class:

github.com/sky-uk/gonsx/api/dhcprelay

The Dhcp relay behaves differently in the API and as such it doesn't have a create and only an update and delete. The delete function will remove the whole relay and all of its information. If you do not wish to do this and only remove interfaces from the DHCP relay, then you must run an update instead.

Read:

api := dhcp.NewGetAll(edgeId)
nsxclient.Do(api)

Update:

api := dhcprelay.NewUpdate(dhcpIpAddress, edgeId, relayAgentslist)
nsxclient.Do(api)

Delete:

api := dhcprelay.NewDelete(edgeId)
nsxclient.Do(api)

Security Tag

Security tag resource. This resource will call the security tag api within NSX. Import the following class:

github.com/sky-uk/gonsx/api/securitytag

Create:

api := securitytag.NewCreate(name, desc)
nsxclient.Do(api)

Read:

api := securitytag.NewGetAll()
nsxclient.Do(api)

Update:

Not yet implemented

Delete:

api := securitytag.NewDelete(securitytagID)
nsxclient.Do(api)

Detach:

api := securitytag.NewDetach(securityTagID, vmID)
nsxclient.Do(api)

Attach:

api := securitytag.NewAttach(securityTagID, vmID)
nsxclient.Do(api)

Service

Service resource. This resource will call the service api with NSX. Import the following class:

github.com/sky-uk/gonsx/api/service

Create:

api := service.NewCreate(scopeID, name, desc, proto, ports)
nsxclient.Do(api)

Read:

api := service.NewGetAll(scopeID)
nsxclient.Do(api)

Update:

Not yet implemented

Delete:

api := service.NewDelete(serviceID)
nsxclient.Do(api)

Security Group

Security Group resource. This resource will call the security group api with NSX. Import the following class:

github.com/sky-uk/gonsx/api/securitygroup

Create:

api := securitygroup.NewCreate(scopeID, name, setOperator, criteriaOperator, criteriaKey, criteriaValue, criteria)
nsxclient.Do(api)

Read:

api := securitygroup.NewGetAll(scopeID)
nsxclient.Do(api)

Update:

Not yet implemented

Delete:

api := securitygroup.NewDelete(serviceID)
nsxclient.Do(api)

Security Policy

Security Policy resource. This resource will call the security policy with NSX. Import the following class:

github.com/sky-uk/gonsx/api/securitypolicy

Create:

api := securitypolicy.NewCreate(name, precendence, desc, securityGroupsIDs, actions)
nsxclient.Do(api)

Read:

api := securitypolicy.NewGetAll()
nsxclient.Do(api)

Update:

Not yet implemented

Delete:

api := securitypolicy.NewDelete(securityPolicyID, force)
nsxclient.Do(api)

AddOutboundFirewall:

securityPolicyToModify := getAllAPI.GetResponse().FilterByName(securityPolicyName)

// we will use a help function to add a firewall rule.
securityPolicyToModify.AddOutboundFirewallAction(
	firewallName,
	action,
	direction,
	secGroupObjectIDs,
	serviceIDs,
)

updateAPI := securitypolicy.NewUpdate(securityPolicyToModify.ObjectID, securityPolicyToModify)
nsxclient.Do(updateAPI)

RemoveFirewall:

securityPolicyToModify := getAllAPI.GetResponse().FilterByName(securityPolicyName)

securityPolicyToModify.RemoveFirewallActionByName(firewallName)

updateAPI := securitypolicy.NewUpdate(securityPolicyToModify.ObjectID, securityPolicyToModify)
nsxclient.Do(updateAPI)
