I have seen many solutions including some answers shown here , but none of them takes into account whether rules are inherited or not.
Therefore I suggest the following approach that considers rule inheritance neatly wrapped into a class :. However, I made the experience that this does not always work on remote computers as you will not always have the right to query the file access rights there. The solution in that case is to try; possibly even by just trying to create a temporary file, if you need to know the access right before working with the "real" files.
The answers by Richard and Jason are sort of in the right direction. However what you should be doing is computing the effective permissions for the user identity running your code. None of the examples above correctly account for group membership for example. I'm pretty sure Keith Brown had some code to do this in his wiki version offline at this time of The.
This is also discussed in reasonable detail in his Programming Windows Security book. Computing effective permissions is not for the faint hearted and your code to attempt creating a file and catching the security exception thrown is probably the path of least resistance. The accepted answer by Kev to this question doesn't actually give any code, it just points to other resources that I don't have access to. So here's my best attempt at the function.
It actually checks that the permission it's looking at is a "Write" permission and that the current user belongs to the appropriate group. It might not be complete with regard to network paths or whatever, but it's good enough for my purpose, checking local configuration files under "Program Files" for writability:. IMO, you need to work with such directories as usual, but instead of checking permissions before use, provide the correct way to handle UnauthorizedAccessException and react accordingly.
This method is easier and much less error prone. And here's a reference you could also look at. My code might give you an idea as to how you could check for permissions before attempting to write to a directory.
Since the static method 'GetAccessControl' seems to be missing from the present version of. How are we doing? Please help us improve Stack Overflow. Take our short survey.

Thanks for the code, though one thing, the caller may get the false impression that write permission is missing if the user is able to write but not able to delete. How do I use that flag? Same here. I was caught unaware and updated one of my clusters, and --write-kubeconfig-mode is not documented. Should I specify it during the initial install, edit the systemd unit The command as-is installs fine, but kubectl won't work without using sudo.
However, default sudo setup in CentOS 7 does not let you use the default kubectl path. Note that if you just want to allow access in an already existing install you can edit the k3s. You do have to restart the service if you are trying to change the perms via env variable or command line option. It rewrites the file and sets permissions on startup. For who installed k3s with binary, using k3s server --write-kubeconfig-mode to start the server fixed it.
If you're using k3sup to install k3s, add this flag to your install --k3s-extra-args '--write-kubeconfig-mode '. Note: You may run into issues if you use this on your agents, I hit this error: flag provided but not defined: -write-kubeconfig-mode. Based on jr comment, here's a one liner that copies the k3s.
