Hi.

I have an etcd 2.3.1 cluster with Kubernetes 1.2.4 on my Ubuntu 14.04 x64 VM.

Here's the status:

root@ubuntu:/kubernetes/cluster# etcdctl cluster-health
member ce2a822cea30bfca is healthy: got healthy result from http://192.168.134.129:4001
cluster is healthy

Then I browsed to http://henszey.github.io/etcd-browser/ in this VM's firefox, entered http://192.168.134.129:4001 and click Go!. It gave me:

Request failed - - http://192.168.134.129:4001/v2/keys/

But when I opened the http://192.168.134.129:4001/v2/keys/ address in another tab of my Firefox, it shows normally:

{"action":"get","node":{"dir":true,"nodes":[{"key":"/registry","dir":true,"modifiedIndex":3,"createdIndex":3},{"key":"/bbb","value":"test","modifiedIndex":70689,"createdIndex":70689},{"key":"/111","value":"333","modifiedIndex":35380,"createdIndex":35380},{"key":"/aaa","value":"111","modifiedIndex":50991,"createdIndex":50991},{"key":"/aab","dir":true,"modifiedIndex":35980,"createdIndex":35980},{"key":"/coreos.com","dir":true,"modifiedIndex":13,"createdIndex":13}]}}

So I wonder where it's wrong? Thanks!

@hsluoyz @wbwangk
Might be an issue with Access-Control-Allow-Origin
See if this happens:

There're many chrome extensions to solve this, such as ForceCORS

I believe if you use Docker version of etcd browser, this won't happen.

me to seeing something similar on my mac w/ request failed. needs more debug logs (connection refused? client error?). curl http://127.0.0.1:2379/v2/keys works for me, but the client running locally doesnt

[hsluoyz]

@henszey Anybody here still?

[hsluoyz]

etcd has released v3 for some time now, does this browser still work for etcd v3?

I faced same issue even though I run through docker image.

I got below error when I see logs of the etcd-brower docker image.

root@ubuntu:~# docker logs -f etcd-browser
proxy /api requests to etcd on 183.110.81.176:4001

Chrome doesn't allow to use cross-domain for localhost

how to resolve this problem ?

[qianlnk]

thank you @xh4n3.

my env:
docker-machine:
192.168.99.100 etcd0
192.168.99.101 etcd1
192.168.99.102 etcd2

and run etcd-browser:

docker run -d -it --name etcd-browser -p 12345:8000 --env ETCD_HOST=192.168.99.100 --env ETCD_PORT=4001 etcd-browser

I insalled ForceCORS and resolve this problem. here is my setting list:

setting for:
http://192.168.99.100:4001/*

header name	header value
Access-Control-Allow-Origin	*
Access-Control-Allow-Methods	*

To resolve this question (Request failed 404),you should edit server.js add to the values of ca_file、key_file、cert_file.such as
var ca_file = process.env.ETCDCTL_CA_FILE || '/etc/kubernetes/pki/etcd/ca.crt';
var key_file = process.env.ETCDCTL_KEY_FILE || '/etc/kubernetes/pki/etcd/server.key';
var cert_file = process.env.ETCDCTL_CERT_FILE || '/etc/kubernetes/pki/etcd/server.crt';
