I am developing a mutating webhook with kind and as I understand, the API end-point should be https. The certificate and key of the API server should be signed with the CA of the cluster itself so as to get around issue of self-signed certificates. And, for that, the following are the recommended steps:

1. Create key - openssl genrsa -out app.key 2048
2. Create CSR - openssl req -new -key app.key -subj "/CN=${CSR_NAME}" -out app.csr -config csr.conf
3. Create CSR object in kubernetes - kubectl create -f csr.yaml
4. Approve CSR - kubectl certificate approve csr_name
5. Extract PEM - kubectl get csr app.csr -o jsonpath='{.status.certificate}' | openssl base64 -d -A -out app.pem

Notes
1. The csr.conf has details to set-up the CSR successfully.
2. The csr.yaml is written for the kuberenetes kind CertificateSigningRequest.
3. The csr_name is defined in CertificateSigningRequest.
4. The spec.request in csr.yaml is set to cat app.csr | base64 | tr -d '\n'. 5. The app.pem and app.key are used to set-up the https end-point.

The end-point is definitely reachable but errors out as:

How do I set the Kendo Grid Column Width in Angular SCSS? The following will set the width in Angular HTML ,

We have looked at numerous SO post that deal with the SD CARD also the SO post which seems to be the Gold Standard Gold Standard But it deals with permissions we are not asking about permission. The question deals with finding another way to determine if the SD CARD is mounted. This question only wants to deal with SDK 23+ The article that discuss FUSE is at this link FUSE

We have tried this code that when the emulator has the SD CARD ejected returns or evaluates to TRUE. Other similar configuration from SO have also been tested. My question is not only how to detect if the SD CARD is mounted but why is this code failing? We are not sure if this code can be tested on an emulator or if a real device is needed. We feel this code failure is because of the concept of the term EXTERNAL storage not meaning an actual SD CARD but making reference to the secondary EXTERNAL storage that is internal.
