    Hi @nkristianto, could you provide the output from "ip a" and from "kubectl get nodes" and "kubectl get pods -o wide --all-namespaces"?

    hi @chrispokorni this id the output

    i still cannot run the tunnel,

  • Thanks for the output. If the master is not ready, it will not allow for any pods to start either.
    Where are you running your nodes? Are you on GCP, AWS, Azure, Virtual box, VMware? What are the sizes of your nodes?
    Were any of the previous outputs inconsistent with the ones presented in the lab (during updates, upgrades, installs)?

  • hi @chrispokorni,
    thanks for your reply

    i am using GCP to running the nodes and i am using n1 standard

    i am following the lab step by step, and nothing different output until step 11

  • There may be such issues when there are not enough resources on the VM for the Kubernetes cluster to start.
    Are they n1-standard-2 with 2 vCPUs and 7.5 GB. Also make sure you have a firewall rule to enable all traffic (all sources, all ports, all protocols).
    New nodes and a re-install have fixed similar issues in the past.

  • hi @chrispokorni
    the issue is fixed

    the root cause is because : yes, you're right. i dont have enough resource to run the nodes

    thanks for the reply
