Re: [openstack-dev] [openstack-helm] Question about API endpoints

2018-03-04 Thread Hyunsun Moon 
Hi Yoshihiko,

If you have physical LB in your environment, you might want to make use of 
NodePort for distributing the access to multiple controller nodes. In that 
case, it is recommended to set Values.network.external_policy_local to true so 
that you could eliminate unnecessary hops.
Ingress backed by nginx could be used of course, but as you pointed, IP address 
of the node where ingress pod resides will be the address you’re accessing, 
which might not be desirable in many use cases.
If you plan to try it on GCP/GKE, where the ingress controller is backed by 
GCP’s load-balancer service, NodePort + ingress seems valid option for exposing 
your service to external.
FYI, https://cloud.google.com/kubernetes-engine/docs/tutorials/http-balancer 


Hope this helps.

Thanks Liping.
FYI, I use Docker version 17.06.0-ce.

$ docker --version
Docker version 17.06.0-ce, build 02c1d87

[openstack-dev] [kuryr] Subnet pool does not exist error

2017-07-11 Thread Hyunsun Moon 
Hi all,
I’m getting an exception when creating a service with Kuryr network.

I created and installed kuryr plugin by building plugin rootfs from the source 
code.
Here’s what I did after that.

$ sudo docker network create --driver=kuryr/libnetwork2:latest 
--ipam-driver=kuryr/libnetwork2:latest --subnet=10.10.10.0/24 
--gateway=10.10.10.1 kuryr-net
$ sudo docker service create --name redis --network kuryr-net redis:3.0.6
Neutron does not get any request from Kuryr.
Here’s the error message collected from /var/log/kuryr/kuryr.log.
2017-07-11 09:21:06.950 12 INFO kuryr_libnetwork.controllers [-] Creating

2017-07-11 09:36:28.121 13 ERROR kuryr
I tried creating a network with existing Neutron subnetpool as below, but the 
result was the same.
$ sudo docker network create --driver=kuryr/libnetwork2:latest 
--ipam-driver=kuryr/libnetwork2:latest --subnet=10.10.10.0/24 
--gateway=10.10.10.1 --ip-range=10.10.10.0/24 -o neutron.pool.name=kuryr 
--ipam-opt=neuton.pool.name=kuryr kuryr-net

Any suggestion?
