Kubernetes storing persistent files

Question

What's the best way to store a persistent file in Kubernetes? I have a cert (.pfx) and I want to be passing to the application its path. From the looks of it it can't be stored in secrets. Was thinking about a volume but the question is how do I upload the file to it? And which type of volume to choose? Or is there any other efficient way?

Answer 1

you can copy your ".pfx" file into local directory like "/home/certs/" and than mount this directory inside to your pod,check below yaml

kind: Pod
apiVersion: v1
metadata:
  name: secret-test-pod
spec:
  volumes:
  - name: localhostpath
    hostPath:
      path: /home/certs # path on local file system
      type: DirectoryOrCreate # create if not exist
  containers:
  - name: ...
    image: ...
    volumeMounts:
    - name: localhostpath
      mountPath: "/root/certs" # path inside pod or containers
