---------------------------------
Summary: kerberos krb5.conf file is mounted as empty directory for
customer file name
Key: FLINK-24212
URL: https://issues.apache.org/jira/browse/FLINK-24212
Project: Flink
Issue Type: Bug
Components: Deployment / Kubernetes
Affects Versions: 1.13.2, 1.13.1, 1.12.1
Reporter: LiuZeshan
Fix For: 1.14.1
Attachments: mykrb5conf.yaml
>From [FLINK-18971]，we can mount kerberos krb5 conf file to pod with path
>/etc/krb5.conf，however if the krb5 conf file is not named krb5.conf (e.g named
>mykrb5.conf)，the mount path /etc/krb5.conf in pod will be an empty directory,
>not the file the we expected.
{code:java}
root@mykrb5-conf-test-6dd5c76f87-vfwh5:/# ls /etc/krb5.conf/ -la
total 8
drwxrwxrwx 2 root root 4096 Sep 8 10:42 .
drwxr-xr-x 1 root root 4096 Sep 8 10:42 ..{code}
The reason is that, the code in
[KerberosMountDecrator#decroateFlinkPod|https://github.com/apache/flink/blob/7e91e82fca999ddefa7ebdf198b8cfd3b6998b8b/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/decorators/KerberosMountDecorator.java#L110],
we create the deployment like this:
{code:java}
volumeMounts:
- mountPath: /etc/krb5.conf
name: my-krb5conf-volume
subPath: krb5.conf
...
volumes:
- configMap:
defaultMode: 420
items:
- key: mykrb5.conf
path: mykrb5.conf
name: my-krb5conf
name: my-krb5conf-volume
{code}
path: mykrb5.conf should be set to const value "krb5.conf", not the file name
that user provide.
we can use the yaml description file attachment to reproduce the problem.
[^mykrb5conf.yaml]
