Sorry about that, let's try some debugging. Just FYI, when you run vagrant up, Vagrant builds two clusters: an EPIC Gateway cluster and a client cluster. It looks like the error is that the client is timing out waiting for the server to finish.

Let's try breaking the process down into two steps: bring up the server first, then the client.

$ vagrant up --no-destroy-on-error gateway

The no-destroy-on-error flag tells Vagrant to not clean up if anything goes wrong so we can figure out what.

If that succeeds then we can bring up the client:

$ vagrant up --no-destroy-on-error gwclient

thank you for your answer , but when i try

 $ vagrant up --no-destroy-on-error gateway

it end with

EPIC uses cert-manager to issue certificates, so installing cert-manager is part of the installation process. In your case something has gone wrong with the cert-manager installation so the pods aren't reaching a ready state.

Starting from your dev-test-environment directory, you can ssh to the gateway by running:

$ vagrant ssh gateway
Last login: Thu May 16 14:06:58 2024 from 192.168.121.1
vagrant@epic-gateway:~$ 

Once you've done that, you can examine the cert-manager pods to see what's gone wrong:

vagrant@epic-gateway:~$ kubectl get pods --namespace=cert-manager 
NAME                                       READY   STATUS    RESTARTS   AGE
cert-manager-557c8c599f-qhgl6              1/1     Running   0          10m
cert-manager-cainjector-587fd9f888-rtjr5   1/1     Running   0          10m
cert-manager-webhook-6784457987-p4nqk      1/1     Running   0          10m

That's what you should see, but you'll probably see something different. It will probably be useful to "describe" the cert-manager pod, or any pod that's not Running.

Allright. I found something wrong but i have repaired it:
Actually, i find that flannel dose not work because of
Warning DNSConfigForming 6d2h (x74 over 6d4h) kubelet Nameserver limits were exceeded, some nameservers have been omitted, the applied nameserver line is: 4.2.2.1 4.2.2.2 208.67.220.220
Normal SandboxChanged 9m4s kubelet Pod sandbox changed, it will be killed and re-created.
Warning Failed 9m2s (x2 over 9m3s) kubelet Error: services have not yet been read at least once, cannot construct envvars
so that cert-manager can not find "/run/flannel/subnet.env".
and i find that kubelet is using config file "/run/systemd/resolve/resolv.conf"
and the content of "/run/systemd/resolve/resolv.conf" has 4 nameserver.
and then i delete one, restart flannel and cert-manager, gateway works well now and all pods are ready,
but gwclient is still not working because：

• name: Poll the web service to make sure that it's alive
  ansible.builtin.command: curl --insecure -s -o /dev/null -w "%{http_code}" https://{{ ws_hostname }}/api/epic
  register: result
  until: result.stdout == '401'
  retries: 36
  delay: 20
  failed, i will check it and thank you for your help!
