QUESTION
Two years ago while I took CKA exam, I already have this question. At that time I only could do was to see k8s.io official documentation. Now just curious on generating pv / pvc / storageClass via pure kubectl cli. What I look for is similar to the similar logic as deployment, for example:
...ANSWER
Answered 2021-Apr-19 at 16:44There is no kubectl command to create a resource like PV, PVC, and storage class.
From certificate points of view, you have go over k8.io and look for the PV, PVC, and storage class under the task link.
Under task link, most of the YAML will be the same and for now, this is one of the fastest ways in exam.
QUESTION
I recently created a Console app which held the context of Pkcs11Interop library, along with HSM dll. It worked fine, however I needed to rewrite the code to Windows Service (I hosted it as gRPC service since it's .NET Core). After hosting WS, it ocurred that the slot list on factories.Pkcs11LibraryFactory.LoadPkcs11Library(factories, libraryPath, AppType.MultiThreaded).GetSlotList(SlotsType.WithOrWithoutTokenPresent).Find(slot => slot.SlotId == slotId) returns an empty list of slots, even though it returned list of 3 elements in console app.
...ANSWER
Answered 2021-Mar-28 at 16:47Pkcs11Interop returns slots received by calling C_GetSlotList function of unmanaged PKCS#11 library. So if you get 0 slots then C_GetSlotList returned 0 slots. You need to discuss this situation with the vendor of your PKCS#11 library who might know why their library does not see any slots.

QUESTION
I am generating a RSA key pair with AWS cloud HSM with PKCS11Interop c# library on top of AWS vendor PKCS library. Wanted to export a public key from HSM with PKCS 11 getAttributeValue methods.
The response states that attributes cannot be read, I have marked all the attributes values correctly to be able to export a key, can somebody point out what I am doing wrong ?
My sample code
...ANSWER
Answered 2020-May-02 at 08:12RSA public key objects do not have CKA_VALUE attribute. Instead, there are two attributes called CKA_MODULUS and CKA_PUBLIC_EXPONENT that make up the key value.
