[BUG] Cluster View not properly reflecting the status of the nodes

sebastianricaldoni commented 3 years ago

Describe the bug I'm running a 3-node cluster using docker When I stop one of the containers (etcd1) I don't see that node as being down.

To Reproduce

Setup the cluster

$ HTTPIP=http://<YOUR_IP>
$ CLUSTER="etcd0=$HTTPIP:2380,etcd1=$HTTPIP:2480,etcd2=$HTTPIP:2580"
$ ARGS="etcd -listen-client-urls http://0.0.0.0:2379 -listen-peer-urls http://0.0.0.0:2380 -initial-cluster-state new -initial-cluster $CLUSTER"
$ IMG="quay.io/coreos/etcd:v3.4.14"
$ docker run -d -p 2379:2379 -p 2380:2380 --name etcd0 $IMG $ARGS -name etcd0 -advertise-peer-urls $HTTPIP:2380
$ docker run -d -p 2479:2379 -p 2380:2380 --name etcd1 $IMG $ARGS -name etcd1 -advertise-peer-urls $HTTPIP:2480
$ docker run -d -p 2579:2379 -p 2380:2380 --name etcd2 $IMG $ARGS -name etcd2 -advertise-peer-urls $HTTPIP:2580

It should look something like this

Open ETCD Manager and point to the cluster

Note Make sure to click on the Status button for each node in order to get the green check ✅

Stop one of the nodes

$ docker stop etcd2
$ docker ps

Go back to ETCD Manager and check the status again

Expected behavior As described above, I'm expecting the etcd2 node to show as down or some sort of UI hint. I'm currently in discovery mode checking on how etcd works, mainly aspects such as high availability (HA) and fault tolerance (FT). This means I could be missing some key / critical aspect as on how etcd works, specially around clustering?

Screenshots Supplied above

Desktop (please complete the following information):

OS: Windows / WSL2 / Docker
OS version: Windows 10
ETCD manager version 1.2
Additional context Add any other context about the problem here.
