Discussion on: Mount S3 Objects to Kubernetes Pods

[Big Bunny]

I tried to use the sharing method to complete the entire demo, but unfortunately this didn't work. Because the goofys mount directory( /var/s3fs) in daemonset is not the same as the directory I want to share with the host(/var/s3fs:shared);

/otomato # df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/nvme0n1p1           50.0G      4.7G     45.3G   9% /var/s3fs:shared
poc-s3goofys-source 1.0P         0      1.0P   0% /var/s3fs

Is there any configuration I missed?

What's your node OS? Is mount propagation enabled in the container runtime? See this note here: kubernetes.io/docs/concepts/storag...
