Hostpath Mount not working

[whitepiratebaku]

Hello, is it supposed to work with HostPath mount from node? because it does not seem to work.

[jimmidyson]

Hmm that's an interesting one. This will not work because the strategy expects the volume to be mounted in the way that a configmap (or secret) is mounted (see https://github.com/jimmidyson/configmap-reload/blob/main/configmap-reload.go#L183).

Yeah, thank you

@jimmidyson ok, but what is the reason behind this restriction to "..data" ? Wouldn't it simply work with all kind of data sources ( persistent volumes , etc.) if we skip this restriction?

[jimmidyson]

Originally this was only for configmaps, which work with this ..data strategy, and I can't remember the reason why I enforced this restriction 😅

[jimmidyson]

Thinking about this, the inotify notification required would be different for a hostpath volume or persistentvolume mount, in that what are we watching: the mounted directory, or content in the mounted directory? For configmaps, watching ..data only makes sense as the directory symlink is updated which makes what we're watching much easier. To have more generic support, we would need to think about what we do support and what the UX would be.

i understand, thx for the explanation 👍
