trying to recreate the etcd certs with playbooks/openshift-etcd/redeploy-certificates.yml which completed, but the same error. looking on the master the certs are still valid:

I disabled client auth in etcd by setting ETCD_CLIENT_CERT_AUTH=false, which got me past this error, however the api server is killing the etcd pod with the liveness probe failing:

Liveness probe failed: rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:110: decoding init error from pipe caused \"read parent: connection reset by peer\""2 times in the last minute

I reenabled client auth, as I'm thinking the ssl error is a red herring. Instead I think the liveness probe isn't spawning correctly. Running the liveness probe from the command line works:

etcdctl --cert-file /etc/etcd/peer.crt --key-file /etc/etcd/peer.key --ca-file /etc/etcd/ca.crt --endpoints https://X.X.X.X:2379 cluster-health
member ccd4cb5684c5b1d4 is healthy: got healthy result from https://X.X.X.X:2379
cluster is healthy

@vrutkovs asked to run docker exec directly, and I get the same error as the probe:

docker exec -ti cc1195d1292c bash
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:110: decoding init error from pipe caused \"read parent: connection reset by peer\""

this seems to be JUST an issue with etcd though, as running with any other pod on the node works fine:

docker exec -ti 5364d8e20a2c bash
bash-4.2$ exit
exit

Looking in journalctl and it doesn't appear to have any new info:

We are seeing the same issue with the 3.10 and the liveness checks on the etcd pod. Our issues started on 11/29. Cannot exec into the etcd pod.

so it looks like the issue is related to CentOS 7.6 . talking to a customer with latest 3.11 on centos 7.5 is fine.

I'm having the same issues (#21575) not sure it's just CentOS 7.6 as I'm running RHEL 7.6, just tried deploying with RHEL 7.5 and I get the same issue.

Just like you I'm able to run the liveness probe from the command line and works fine

etcdctl --cert-file /etc/etcd/peer.crt --key-file /etc/etcd/peer.key --ca-file /etc/etcd/ca.crt --endpoints https://XX.XXX.XX.XXX:2379 cluster-health
member e7e46ded4b8f5495 is healthy: got healthy result from https://XX.XXX.XX.XXX:2379 cluster is healthy

running docker exec give me the same error

docker exec -ti 90de6c2163c2 /bin/bash
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:110: decoding init error from pipe caused \"read parent: connection reset by peer\""

We encountered a similar issue on one of our clusters after we updated docker to version 1.13.1-84.git07f3374.el7.centos
We resolved the problem be downgrading docker to version 1.13.1-75.git8633870.el7.centos

origin v3.10.0

Seems to be a later release of docker at fault.

Redhat's solution is to downgrading docker to version 1.13.1-75 (https://access.redhat.com/solutions/3734981) which fixed the issue with etcd crashing for me

Solution:

In CentOS7 do: yum install docker-1.13.1-75.git8633870.el7.centos

This will downgrade the docker version to a working one.
