Custom instance addresses

Modified: 15 Aug 2024 15:38 UTC

In certain instances it may be necessary to allocate a particular MAC address or IP address to a given instance. This procedure shows you how to accomplish this.

Important Note: This section does not apply to addresses on a fabric network (VXLAN) - this only applies to L2/L3 networks that have been created in NAPI. For more information on the VXLAN implementation in Triton, please see Triton networking and fabric guide and Triton networking and fabric operations guide.

Prerequisites

This will require access to the head node of your installation, as root or as a root-equivalent user. You will also need to have already provisioned the instance that you wish to connect to the custom VNIC (either MAC address, IP address, or both).

Additionally, you will need to know the following information:

Placeholder	Replace With	Notes
MAC-ADDRESS	Custom MAC Address	Must be unique within Triton; Only required if specifying a custom MAC address
NIC-KEY	Key to NAPI NICs	MAC Address with colons removed
OWNER-UUID	The UUID of the owner of the instance
VM-UUID	The UUID of the instance the VNIC is to be connected to
NETWORK-UUID	The UUID of the network the VNIC is part of
IP-ADDRESS	Your custom IP Address	Must be in the range of the network specified above
NIC-TAG	NIC Tag of Network for your specified IP address	Only required if specifying an IP address
VLAN-ID	VLAN ID of the Network for your specified IP address	Only required if specifying an IP address

Notes:

If you delete a custom VNIC from the instance, you will need to recreate it in NAPI.
NAPI is keyed on MAC address with the colons stripped out.
You cannot have two NICs with the same MAC in Triton (other than in fabric or VXLAN networks, where it is segreated by user).
You cannot have two NICs with the same IP address in Triton (other than in fabric or VXLAN networks, where it is segreated by user).

Assigning a MAC address

This procedure will create a VNIC with a custom MAC address and allow you to assign it to an instance.

Create the VNIC

Run the following command, replacing the placeholders with your information

headnode#  sdc-napi /nics -X POST -d '{ "mac": "MAC-ADDRESS", "primary": false, "owner_uuid": "OWNER-UUID", "belongs_to_uuid": "VM-UUID", "network_uuid": "NETWORK-UUID", "belongs_to_type": "zone" }'

You should see output that looks like this:

headnode# sdc-napi /nics -X POST -d '{ "mac": "22:50:56:34:60:4c", "primary": false, "owner_uuid": "76ce0bcd-d418-ce8c-bbee-90dd4d4ea48e", "belongs_to_uuid": "420ee790-9d60-6dbe-a3c4-fc6f86e10f14", "network_uuid": "d534f307-da9b-4df5-86d6-0c3fc6905e46", "belongs_to_type": "zone" }'

}

At this point we have created the VNIC; this VNIC can be viewed in NAPI by using the MAC address with the colons stripped as a key. For example, to view the VNIC we created above you could query NAPI with:

headnode# sdc-napi /nics/NIC-KEY

This will return the following:

}

Assign to the instance

At this point, the VNIC has been created but even though NAPI has been updated with the instance ownership information for the VNIC, the instance has not been updated through VMAPI.

To do this, we run the following command on the head node, replacing VM-UUID and MAC-ADDRESS with your information from above, which will generate a workflow.

headnode# sdc-vmapi /vms/VM-UUID?action=add_nics  -X POST -d '{"macs": ["MAC-ADDRESS"]}'

You should see output that looks like this:

headnode# sdc-vmapi /vms/420ee790-9d60-6dbe-a3c4-fc6f86e10f14?action=add_nics  -X POST -d '{"macs": ["22:50:56:34:60:4c"]}'

}

The job_uuid returned above is the identifier for the workflow that was created to attach your VNIC to your instance. This can be viewed in the Operations Portal under the Jobs page, or it can be viewed by running the following command:

headnode# sdc-workflow /jobs/JOB-UUID

Where you replace JOB-UUID with the UUID returned from the POST to VMAPU above.

Reboot the instance

When the workflow runs, the the instance will reboot - this is required when adding a VNIC to an instance.

Verify the VNIC

Once the instance has been rebooted, you will be able to see the new VNIC in the list of adapters. For example, in SmartOS you can run ifconifg(1m) with the -a flag to see all the adapters

container# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
net0: flags=40001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,L3PROTECT> mtu 1500 index 2
        inet 192.168.212.134 netmask ffffff00 broadcast 192.168.212.255

        inet6 ::1/128

This can be verified in the Operations Portal

As well as through the VMAPI endpoint:

You can also verify that you can ping it (Note: you will need to do this from a host that has a route to the IP address you have just created.)

$ ping 192.168.212.138

64 bytes from 192.168.212.138: icmp_seq=2 ttl=255 time=0.329 ms

And see the newly created MAC in the arp table:

$ arp -a | grep 138
? (192.168.212.138) at 22:50:56:34:60:4c on en0 ifscope [ethernet]

Assigning an IP address

This procedure will create a VNIC with a custom IP address and allow you to assign it to an instance.

Create the VNIC

Run the following command, replacing the placeholders with your information

headnode# sdc-napi /nics -X POST -d '{ "vlan_id": "VLAN-ID", "nic_tag": "NIC-TAG", "ip" :"IP-ADDRESS",  "primary": false, "owner_uuid": "OWNER-UUID", "belongs_to_uuid": "VM-UUID", "network_uuid": "NETWORK-UUID", "belongs_to_type": "zone" }'

You should see output that looks like this:

Assign to the instance

At this point, the VNIC has been created but even though NAPI has been updated with the instance ownership information for the VNIC, the instance has not been updated through VMAPI.

To do this, we run the following command on the head node, replacing VM-UUID and MAC-ADDRESS with your information from above, which will generate a workflow.

headnode# sdc-vmapi /vms/VM-UUID?action=add_nics  -X POST -d '{"macs": ["MAC-ADDRESS"]}'

You should see output that looks like this:

headnode# sdc-vmapi /vms/420ee790-9d60-6dbe-a3c4-fc6f86e10f14?action=add_nics -X POST -d '{"macs": ["99:50:56:34:60:4d"]}'

}

headnode# sdc-workflow /jobs/JOB-UUID

Where you replace JOB-UUID with the UUID returned from the POST to VMAPI above.

Reboot the instance

When the workflow runs, the the instance will reboot - this is required when adding a VNIC to an instance.

Verify the VNIC

Once the instance has been rebooted, you will be able to see the new VNIC in the list of adapters. For example, in SmartOS you can run ifconifg(1m) with the -a flag to see all the adapters

container# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
net0: flags=40001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,L3PROTECT> mtu 1500 index 2
        inet 192.168.212.134 netmask ffffff00 broadcast 192.168.212.255
        ether 90:b8:d0:3d:5b:6
net1: flags=40001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,L3PROTECT> mtu 1500 index 3
        inet 192.168.212.186 netmask ffffff00 broadcast 192.168.212.255
        ether 99:50:56:34:60:4d
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
        inet6 ::1/128

This can be verified in the Operations Portal

As well as through the VMAPI endpoint:

headnode# sdc-vmapi /vms/420ee790-9d60-6dbe-a3c4-fc6f86e10f14 | json -Hag nics

  },

    "network_uuid": "d534f307-da9b-4df5-86d6-0c3fc6905e46"
  }
]

You can also verify that you can ping it (Note: you will need to do this from a host that has a route to the IP address you have just created.)

$ ping 192.168.212.186
PING 192.168.212.186 (192.168.212.193): 56 data bytes

64 bytes from 192.168.212.186: icmp_seq=2 ttl=255 time=0.329 ms

And see the newly created MAC in the arp table:

$ arp -a | grep 186
