So I've deployed a local single-node cluster. For some reason the config maps doesn't create file in conatiner. I followed the example in the configmaps guide and /etc/config/special.how should be created below but there is no such file there. Is there something that I'm doing wrong:
[root@nonipo brs-kubernetes]# kubectl create -f example.yaml
configmap "special-config" created
pod "dapi-test-pod" created
[root@nonipo brs-kubernetes]# kubectl exec -it dapi-test-pod -- sh
/ # cd /etc/config/
/etc/config # ls
/etc/config # ls -alh
total 4
drwxrwxrwt 2 root root 40 Mar 23 18:47 .
drwxr-xr-x 7 root root 4.0K Mar 23 18:47 ..
