Canceling A firewall with Softlayer API

Question

I am trying to Use the Python API FirewallManager class's cancel_firewall() function to cancel all of the firewalls in an account.

# Connect to soflayer account
client = SoftLayer.create_client_from_env(username=user, api_key=api)

firewall_manager = SoftLayer.FirewallManager(client=client)
# Get a list of all of the firewalls in an account
firewalls = firewall_manager.get_firewalls()
# Cancel each firewall
for firewall in firewalls:
    dedicated = bool(firewall["dedicatedFirewallFlag"])
    firewall_manager.cancel_firewall(firewall_id=firewall["id"], dedicated=dedicated )

but when I run this code I get the error:

SoftLayerAPIError(SoftLayer_Exception_ObjectNotFound): Unable to find object with id of '284501'.

The code for canceling says that it takes a "firewall_id" but the id I give it doesnt seem to be working.... the source code for the manager is here

As I see in your code, you are sending the firewall['id'] to cancel_firewall method.

Reviewing how SLCLI works, it is filtering depending if the firewall type is a vlan, vs or server. Following the same idea, you should take in account the existing filters in the following link:

https://github.com/softlayer/softlayer-python/blob/master/SoftLayer/CLI/firewall/list.py

E.g:

• VSI: firewall['id'] == vlan['firewallGuestNetworkComponents']*
• Server: firewall['id'] == vlan['firewallNetworkComponents']
• Vlan: firewall['id'] == vlan['networkVlanFirewall']['id']

Well, it is something tedious to understand how it works, anyway, I used the bellow script, which uses the FirewallManager to delete all firewalls:

"""
cancels all firewall from the account

        print(firewall_manager.cancel_firewall(firewall_id, dedicated=True))
    else:
        raise exceptions.CLIAbort('Unknown firewall type: %s' % firewall_type)

I hope it helps, let me know if you have any question or comments about it. Keep in mind that the script is just an idea, it can be improved.
