Hi *,

sorry for the repost, I forgot to edit the subject line.

I'm trying to get magnum to work in an Ussuri environment. There are  
some issues I'm facing and would like to ask you for some pointers  
what I might be doing wrong. The control nodes would have access to  
the internet through a proxy, I would like to avoid that but I don't  
know yet what my local registry needs to look like. So to get it  
working I'll go with the http_proxy. The first attempts failed due to  
various reasons, now I'm stuck at the invalid discovery_url. After  
some search I found that I need to create a new discovery_url like this:

controller02:~ # curl --silent -H "Accept: text/plain"  
https://discovery.etcd.io/new?size=1

Using that new URL I try to create a cluster like this:

controller02:~ # openstack coe cluster create kubernetes-cluster-8  
--cluster-template 9c7cfeff-3807-4b06-a4e6-a76f2ae0f612 --master-count  
1 --node-count 1 --keypair eblock --discovery-url  
https://discovery.etcd.io/<UUID>

The template contains the http and https proxy. The resulting error is this:

---snip---
HTTPSConnectionPool(host='discovery.etcd.io', port=443): Max retries  
exceeded with url: /<UUID>/_config/size (Caused by  
NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object

ETIMEDOUT',)): requests.exceptions.ConnectionError:

[...]
magnum.common.exception.GetClusterSizeFailed: Failed to get the size  
of cluster from 'https://discovery.etcd.io/<UUID>'.

The stack trace is a little longer, of course, but this is the  
relevant part. Can anyone point me in the right direction? What am I  
missing? I also tried quay.io since discovery.etcd.io seems to be not  
maintained anymore, but there I can't even generate a new URL.

Any help is greatly appreciated!

Thanks
Eugen
