    It'll throw that until the Netmaker server is running. Netmaker generates the corefile. If you're running an older version, it will also not get generated until you have a dns entry, so coredns will display that error until there's a network and a node.

    per my above comment, You need to change the ip address in the template to be in the range of your service network.

    so search for 10.152.183.53 in the template and change that to something within 10.233.0.0/18

    this is likely a storage class mismatch
  • j

    check which storage classes you have available via "kubectl get sc" and make sure they match what is in the template

    also, you will need RWX

    if you just spun up this microk8s, it will not have RWX storage. The easiest method for getting an RWX storage class is to use NFS

    This is written for DO but will work on microk8s: https://www.digitalocean.com/community/tutorials/how-to-set-up-readwritemany-rwx-persistent-volumes-with-nfs-on-digitalocean-kubernetes

    @User the microk8s is the dns issue, they kubespray cluster is the storage issue.

    you can, but it's not really an issue. The logs are annoying but once netmaker is running and set up it should go away

    ok, so besides coredns, is netmaker running on microk8s and can you log into the ui?
  • i

    incalculable-musician-80046

    09/13/2021, 7:51 PM
    nope, probably because the microk8s is internal lab

    ok, so I would ignore dns until you are able to get into the UI and create a network. It will not affect the rest of the application, and will run normally once you have set up a network. You can even just run "kubectl scale deploy netmaker-dns --replicas=0" to turn it off until you're up and running

    in the newer version of the server, the Corefile gets generated on startup so this doesnt happen, but in the older version (if you're going off of the tutorial), the Corefile doesn't get generated until a node is created

    09/13/2021, 7:55 PM
    sooo is there a way to use the newer version ?
  • j

    jolly-london-20127

    09/13/2021, 7:56 PM
    yes, just go into the github repo and use the template from the master branch
