I am pretty new to Kubernetes so I don't have much idea. Last day a pod went down and I was thinking if I would be able to recover the tmp folder.

So basically I want to know that when a pod in Kubernetes goes down, does it lose access to the "/tmp" folder ?

CodePudding user response：

Unless you configure otherwise, this folder will be considered storage within the container, and the contents will be lost when the container terminates.

Similarly to how you can run a container in docker, write something to the filesystem within the container, then stop and remove the container, start a new one, and find the file you wrote within the container is no longer there.

If you want to keep the /tmp folder contents between restarts, you'll need to attach a persistent volume to it and mount it as /tmp within the container, but with the caveat that if you do that, you cannot use that same volume with other replicas in a deployment unless you use a read-write-many capable filesystem underneath, like NFS.
