Re: [openstack-dev] [octavia] connection to external network

Hi colleagues,

found the solution, it need to be done manually. No corresponding 
Octavia configuration responsible for this.


Everything works, thank you :-)

    +

where "Amphora" is agent which loadbalances requests between "n1" and 
"n2":


  * openstack loadbalancer create --name lb1 --vip-subnet-id
nbt-subnet --project bush
  * openstack loadbalancer listener create --protocol TCP
--protocol-port 80 --name lis1 lb1
  * openstack loadbalancer pool create --protocol TCP --listener lis1
--name lpool1 --lb-algorithm ROUND_ROBIN
  * openstack loadbalancer member create --protocol-port 80 --name n1
--address 1.1.1.11 lpool1
  * openstack loadbalancer member create --protocol-port 80 --name n2
--address 1.1.1.14 lpool1

Everything works (n3-sourced connections to Amphora-agent return 
answers from n1 and n2 respectively in round robin way) and the 
question is how to connect Amphora-agent to external network in order 
to service requests from outside?


In example above, nbt-subnet (which is VIP network) has a virtual 
router which is connected to external network and has all abilities to 
provide e.g. floating ip to Amphora, but I see nothing in octavia 
config files regarding floating ip functions.


Am I missing something? Any ways on connect Web-servers in closed 
(project's) networks with Internet using Octavia / LBaaS?


Thank you!

Hello Volodymyr,

You have two options:
1. When you create your VIP, simply put in your external network as
the vip-subnet-id or vip-network-id. This will allocate a public IP to
the VIP.
2. Use neutron to assign a floating IP to the VIP address of the load
balancer.  From your example, let's say the VIP address of lb1 is
10.0.0.10 on the nbt-subnet with port ID
7e11e63e-7dcb-4b2c-835e-f5cd7ca79acf.  You would use "openstack
floating ip create --port 7e11e63e-7dcb-4b2c-835e-f5cd7ca79acf
external".  This will assign a floating IP to the VIP address.

Option 1 will have better performance as there is no NAT occurring
like there is with a floating IP.

Michael

[openstack-dev] [octavia] connection to external network

2017-11-27 Thread Volodymyr Litovka 

Hello colleagues,

I think I'm missing something architectural in LBaaS / Octavia, thus 
asking there - how to connect Amphora agent to external network? My 
current lab topology is the following:


    +
    |
    |    ++
    +   ++ n1 |
    |    +-+    |    ++
    ++ Amphora ++
    |    +-+    |    ++
  m | n ++ n2 |
  g | b |    ++    + e
  m | t |  | x
  t |   |    ++    | t
    | s ++ vR ++ e
    | u |    ++    | r
   ++ b |  | n
   | Controller | n |    ++    | a
   ++ e |+ n3 |    + l
  t |    ++
    +

where "Amphora" is agent which loadbalances requests between "n1" and "n2":

 * openstack loadbalancer create --name lb1 --vip-subnet-id nbt-subnet
   --project bush
 * openstack loadbalancer listener create --protocol TCP
   --protocol-port 80 --name lis1 lb1
 * openstack loadbalancer pool create --protocol TCP --listener lis1
   --name lpool1 --lb-algorithm ROUND_ROBIN
 * openstack loadbalancer member create --protocol-port 80 --name n1
   --address 1.1.1.11 lpool1
 * openstack loadbalancer member create --protocol-port 80 --name n2
   --address 1.1.1.14 lpool1

Everything works (n3-sourced connections to Amphora-agent return answers 
from n1 and n2 respectively in round robin way) and the question is how 
to connect Amphora-agent to external network in order to service
