Re: [magnum]: K8s cluster creation times out. OpenStack Train : [ERROR]: Unable to render networking. Network config is likely broken

Hi Donny,

Do you mean Fedore CoreOS or just CoreOS? The current CoreOS driver is not actively maintained, I would suggest migrating to Fedora CoreOS and I'm happy to help if you have any question. Thanks.

FWIW I was only able to get the coreos image working with magnum oob.. the rest just didn't work.

Hi Bhupathi,

Firstly, I would suggest setting the use_podman=False when using
fedora atomic image. And it would be nice to set the "kube_tag",
e.g. v1.15.6 explicitly. Then please trigger a new cluster
creation. Then if you still run into error. Here is the debug steps:

1. ssh into the master node, check log /var/log/cloud-init-output.log

2. If there is no error in above log file, then run journalctl -u
heat-container-agent to check the heat-container-agent log. If
above step is correct, then you must be able to see something
useful here.

there working with no issues..

OpenStack Train : [ERROR]: Unable to render networking. Network

Hi Bhupathi,

Could you please share your cluster template? And please make
sure your Nova/Neutron works.

    Folks,

    I am building a Kubernetes Cluster( Openstack Train) and
    using fedora atomic-29 image . The nodes come up  fine ( I
    have a simple 1 master and 1 node) , but the cluster creation
    times out,  and when I access the cloud-init logs I see this
    error .  Wondering what I am missing as this used to work
    before.  I wonder if this is image related .

     

    [ERROR]: Unable to render networking. Network config is
    likely broken: No available network renderers found. Searched
    through list: ['eni', 'sysconfig', 'netplan']

     

    Essentially the stack creation fails in “kube_cluster_deploy”

     

    Can somebody help me debug this ? Any help is appreciated.
