Re: One command to check if all etcd serverd are up and if all masters are connected to this etcd nodes?
etcdhealth probably is sufficient but in any case
I was recently wondering myself what etcdhealth measured + does it
gaurantee the nodes are consistent, synced, no split brain?
We used to do something like this:
curl -L -X PUT http://node1:2379/v2/keys/message -d value="ABCD"
&& curl -L http://node2:2379/v2/keys/message | grep -q ABCD
&& curl -L http://node3:2379/v2/keys/message | grep -q ABCD
To guarantee that writes were working + consistent across the cluster.

Re: One command to check if all etcd serverd are up and if all masters are connected to this etcd nodes?
Hi.
In case the peer* stuff doesn't work I have used this command.
Just as plan B.
###
/usr/bin/etcdctl --peers \
$( awk -F= '/ETCD_LISTEN_CLIENT_URLS=/ {print $2}' < /etc/etcd/etcd.conf )
\
--debug \
--ca-file /etc/origin/master/master.etcd-ca.crt \
--key-file /etc/origin/master/master.etcd-client.key \
--cert-file /etc/origin/master/master.etcd-client.crt \
cluster-health

You can check cluster health with etcdctl command, just run the following
command on one of yours etcd servers:
$ cd /etc/etcd/
$ etcdctl --cert-file peer.crt --key-file peer.key --ca-file ca.crt -C

Hi,
I'm wondering if there are a command to check etcd servers status?
Check if all etcd nodes are up.
```
etcdClientInfo:
ca: master.etcd-ca.crt
certFile: master.etcd-client.crt
keyFile: master.etcd-client.key
urls:
- https://etcd-1.priv.example.com:2379
- https://etcd-2.priv.example.com:2379
- https://etcd-3.priv.example.com:2379
```
Check if this configuration is valid on all OpenShift masters.
Something like `oc get nodes`.
I try `oc status` but I haven't information about etcd configure.
Best regards,
Stéphane

You can check cluster health with etcdctl command, just run the following command on one of yours etcd servers: $ cd /etc/etcd/ $ etcdctl --cert-file peer.crt --key-file peer.key --ca-file ca.crt -C https://:2379 cluster-health --- Diego Castro / The CloudFather GetupCloud.com - Eliminamos a Gravidade 2017-01-13 7:24 GMT-03:00 Stéphane Klein : > Hi, > > I'm wondering if there are a command to check etcd servers status? > Check if all etcd nodes are up. > > ``` > etcdClientInfo: > ca: master.etcd-ca.crt > certFile: master.etcd-client.crt > keyFile: master.etcd-client.key > urls: > - https://etcd-1.priv.example.com:2379 > - https://etcd-2.priv.example.com:2379 > - https://etcd-3.priv.example.com:2379 > ``` > > Check if this configuration is valid on all OpenShift masters. > > Something like `oc get nodes`. > > I try `oc status` but I haven't information about etcd configure. > > Best regards, > Stéphane > -- > Stéphane Klein > blog: http://stephane-klein.info > cv : http://cv.stephane-klein.info > Twitter: http://twitter.com/klein_stephane > > ___ > users mailing list > users@lists.openshift.redhat.com > http://lists.openshift.redhat.com/openshiftmm/listinfo/users > > ___ users mailing list users@lists.openshift.redhat.com http://lists.openshift.redhat.com/openshiftmm/listinfo/users
