Change:

Discussion:
Currently if one wants to view secrets stored in k8s they must follow the process described here: This involves copy&pasting. It seems to me that kubectl could provide a more helpful interface to base64 decrypt the users on behalf of the user saving them the trouble.
The kubelet does decode secrets before exposing them to the pod. Also the title doesn't really make sense. Secrets aren't encrypted so there's nothing to decrypt.

Yes, though this is low priority since we mostly don't want end users to view these once they get into the system.
Why can't that be an API permissions issue? I mean, if I really want to see it, I can just launch a pod to tell me.
I've update the issue title with what I understand as the request. To the best of my understanding this is just a request for us to avoid the need to pipe into base64 when inspecting secrets.

I would like to try to make this work before it rots. cc Any guidance on a preferred implementation?
What do you think about adding support for functions in templates? This would allow someone to use the existing and a template that uses the function -- or a wide variety of other interesting functions as a side effect. I believe (but have not yet tested) that the following might be sufficient to enable the requested behaviour (plus the change to the dependencies list, of course):
Hi I suppose my thoughts on this issue have changed a little since I wrote it. The situation isn't quite as bad as I described as it is possible to decode a secret in one go without then need to copy and paste. i.e.

That said, that is a bit of a mouthful. Also, it might be nice to more easily 'work' with individual secrets and set them as well as get them. Should a user really need to pull down an entire group of secrets and edit a file just to be able to update a single password? For example something like this might be possible: What do people think? PS: Should this have been an issue on [kubectl] instead? PPS: I think some of the ugliness of this comes from configmaps being very similar to secrets except for the base64 encoding. Have there been any thoughts around bringing them into line? If memory serves, it might actually be nicer, due to YAML syntax-shenanigans, if configmaps were base64 encoded too.) [kubectl]:
Hi ... yes, I was thinking that it would be handy to be able to do something like: which is essentially the same as what you did without the overhead of the base64 process, or embed the information in a larger template like or in theory be able to use any of the other Sprig functions if someone found them useful. I think that having the Sprig methods available for generic formatting would just be useful on its own, really. On the topic of a or a , that seems pretty cool. There seem to be quite a lot of options for that I think people might expect to see mirrored in a if it were to exist. Thoughts?
It's also come to my attention that works great on MacOS but on Linux it's , so if someone, say, has a Helm chart where the notes tell the user to retrieve the secret data using one or the other of these, it won't work on the other one. would clearly be a simpler experience for the user than Hmm... thinking further: does does the idea conflict with the documentation in ? Perhaps we'd have to do something like: or similar?

Small tip: you can use which works on both Linux and Mac.
Thank you
Update: I've looked at the huge amount of additional code that would be imported as a result of importing sprig and decided to go with a much smaller change instead, which is simply to implement a template function using . See PR with code and test.
please see the linked PR which addresses the original issue in a minimal fashion -- it simply provides a template function.

It has passed all the tests and needs review; if it's good enough to solve the original problem I'm happy to squash the commits and can hope to get it merged. As far as solving evolved description of the problem, I'm not sure where to start or if you really want me to go in that direction. Would you consider taking this change and splitting the additional work for being able to get / set the contents of an individual key in a secret into a separate issue? If you have any guidance on what you'd like to see with that I'd be happy to take a look, but it might be out of my current grasp.
