failed to constructs tls config: tls: failed to find any PEM data in certificate input #2120

What I use: Ubuntu 18.04 etcd-operator 0.9.4

The requests: I want to user etcd-operator's backup crd to backup my external etcd. my kubernetes's etcd is started in docker(not a pod, started by "docker run" and as a external docker against kubernetes).

The ERROR: I already have etcd-operator-backup pod running in my k8s cluster.

$ kubectl get pods -n etcd
NAME                                                              READY   STATUS    RESTARTS   AGE
etcd-operator-nx-etcd-operator-etcd-backup-operator-f65c8d7g2p2   1/1     Running   0          35m
etcd-operator-nx-etcd-operator-etcd-restore-operator-86b577hgmx   1/1     Running   0          35m

Now, I create a backup.yaml to trigger the backup, here is my backup.yml:

apiVersion: "etcd.database.coreos.com/v1beta2"
kind: "EtcdBackup"
metadata:
  name: etcd-cluster-backup
  namespace: etcd
spec:
  etcdEndpoints: ["https://10.20.11.120:2379"]
  clientTLSSecret: etcd
  storageType: S3
  backupPolicy:
    backupIntervalInSecond: 30
    maxBackups: 6
  s3:
    path: xxxxxxxxxxxx/xxxxxxxxxxx/xxxxx
    awsSecret: aws-etcd

Then, I run:

$ kubectl apply -f backup.yml
#and I got 
$ kubectl describe etcdbackups.etcd.database.coreos.com -n etcd
...
Status:
  Reason:             failed to constructs tls config: tls: failed to find any PEM data in certificate input
  Last Success Date:  <nil>
  Succeeded:          false
...

my secret's name is "etcd", and create by:

$ kubectl create secret generic etcd --from-file=ca.crt --from-file=client.crt --from-file=client.key -n etcd

look into the secret and check:

$ apiVersion: v1

The Question: It seem that the problem is cannot find cert in my secret, but everything I check is absolutely right, did I miss something? I'm trying to use tls to connect to my external etcd. Hope for any reply!

zhangsimingshannonai commented 4 years ago

Finally got the reason, See:https://github.com/coreos/etcd-operator/blob/aeb3e3e0835ec5135cfe50340f59853b5b6fc407/pkg/apis/etcd/v1beta2/backup_types.go#L74-L80

In the secret, data name must set to：

    // data:
    //    "etcd-client.crt": <pem-encoded-cert>
    //    "etcd-client.key": <pem-encoded-key>
    //    "etcd-client-ca.crt": <pem-encoded-ca-cert>

And the order must be same as above... I'm going to close the issue.
