Place CACHEDIR.TAG file in ~/.kube/cache and ~/.kube/http-cache

Open ogarcia opened this issue 4 years ago • 23 comments

What would you like to be added: ~/.kube/cache and ~/.kube/http-cache are cache folders that do not need to be backed up. Until the kubernetes/kubernetes#56402 issue is resolved I propose a trivial change that is add a CACHEDIR.TAG file in these folders following the standard.

TLDR: Create a CACHEDIR.TAG file in ~/.kube/cache and ~/.kube/http-cache containing the following line:

Signature: 8a477f597d28d172789f06886806bc55

Why is this needed: To avoid that the cache dirs ~/.kube/cache and ~/.kube/http-cache are included in backup systems wasting space.

@ogarcia thanks for the issue.

Can you please show me in which case of backup is this happening? Or how this can be reproduced as a problem? I see the files inside my .kube/cache but couldn't figure out how adding the tag file can solve this.

Thanks

@ogarcia thanks for the issue.

If I use a backup system like restic and I do a full backip of my system the directory .kube/cache is included on it. But several backup systems can check if the file CACHEDIR.TAG exists in a folder, and if exist and contains the signature described in my first comment, the contents of the directory are ignored.

Place the file CACHEDIR.TAG at moment of create the directories is like tagging them as this directory is a cache directory and you must not backup it. This behaviour is present in Rust cargo command for example.

@eddiezane Hello, can you take a look at my PR#119648?I have read a lot of discussions on GitHub,for example . Although modifying client-go would be more direct, modifying kubectl may have a smaller impact.
