Hi *, 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 at 0x7fd5e61dcfd0>: Failed to establish a new connection: [Errno 110] ETIMEDOUT',)): requests.exceptions.ConnectionError: HTTPSConnectionPool(host='discovery.etcd.io', port=443): Max retries exceeded with url: /<UUID>/_config/size (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fd5e61dcfd0>: Failed to establish a new connection: [Errno 110] ETIMEDOUT',)) [...] requests.exceptions.ConnectionError: HTTPSConnectionPool(host='discovery.etcd.io', port=443): Max retries exceeded with url: /<UUID>/_config/size (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fd5e61dcfd0>: Failed to establish a new connection: [Errno 110] ETIMEDOUT',)) [...] magnum.common.exception.GetClusterSizeFailed: Failed to get the size of cluster from 'https://discovery.etcd.io/<UUID>'. ---snip--- 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
