i face a problem in step 4 >>> when i use this command
kubectl -n kube-system exec -it etcd-master -- sh -c \
"ETCDCTL_API=3 etcdctl --cert=./peer.crt --key=./peer.key --cacert=./ca.crt \
--endpoints=https://127.0.0.1:2379 member list"

return Error >>> Error: open ./peer.crt: no such file or directory
command terminated with exit code 128

what is the problem ??

@serewicz
I have the exact same problem.
"
student@master:/$ kubectl -n kube-system exec -it etcd-master -- sh -c "ETCDCTL_API=3 etcdctl --cert=./peer.crt --key=./peer.key --cacert=./ca.crt --endpoints=https://127.0.0.1:2379 member list"
Error: open ./peer.crt: no such file or directory
command terminated with exit code 128
"
when navigating to root i can not find the peer.crt file.
"
student@master:/$ pwd
/
"
I also tried using find with no result.
"
student@master:/$ find peer.crt
find: ‘peer.crt’: No such file or directory
"
I guess i have to generate the peer.crt file somehow?
