Can you check the reason about why etcd apisix-etcd-0 not running ? Could you please check the errors ? It is a little challenge from me. I hope you help me on this

Yes, the etcd cluster is not running normal. So you can scale etcd replicas from 3 to 1 . Or you can try preference etcd cluster config like this:


      ETCD_ENABLE_V2:                    true
      ALLOW_NONE_AUTHENTICATION:         yes
      ETCD_NAME:                         cooper-apisix-etcd-1 (v1:metadata.name)
      POD_IP:                             (v1:status.podIP)
      ETCD_ADVERTISE_CLIENT_URLS:        http://$(POD_IP):2379
      ETCD_INITIAL_ADVERTISE_PEER_URLS:  http://$(ETCD_NAME).cooper-apisix-etcd.paas-middleware-workspace-middleware.svc:2380
      ETCD_LISTEN_CLIENT_URLS:           http://0.0.0.0:2379
      ETCD_LISTEN_PEER_URLS:             http://0.0.0.0:2380
      ETCD_INITIAL_CLUSTER:              cooper-apisix-etcd-0=http://cooper-apisix-etcd-0.cooper-apisix-etcd.paas-middleware-workspace-middleware.svc:2380,cooper-apisix-etcd-1=http://cooper-apisix-etcd-1.cooper-apisix-etcd.paas-middleware-workspace-middleware.svc:2380,cooper-apisix-etcd-2=http://cooper-apisix-etcd-2.cooper-apisix-etcd.paas-middleware-workspace-middleware.svc:2380

      ETCD_INITIAL_CLUSTER_STATE:        new

Could you explain the difference between standard and your configuration ?

git clone https://github.com/zaunist/apisix-on-kubernetes.git I have download the etcd.yaml and changed

name: ETCD_ADVERTISE_CLIENT_URLS value: >- http://$(MY_POD_IP):2379 like this for other configuration, I am not sure it works on my side Because when I check ETCD_DEBUG and ETCD_ENABLE_V2, it didn't work

this is my pod yaml using kubectl edit command for the pod but it seems different with your config
