How to access TLS Secret via env variables in Kubernetes?-CodePudding

I have a TLS Secret. And it looks like the following one...

apiVersion: v1 
kind: Secret 
metadata:
  name: tls-ingress-secret 
  namespace: ingress-namespace 
type: kubernetes.io/tls 
data:
  tls.key: | 
    -----BEGIN PRIVATE KEY-----

    -----END CERTIFICATE-----

So the question is "is it possible to retrieve it as an env vars like: "tls.cert" and "tls.key", so I would be able to access it in my application...

What I want to receive from that is...


SSlCertFile := os.Getenv("tls.cert") // cert file with payload. 
SslCertKey := os.Getenv("tls.key") // cert file key.

CodePudding user response：

Example:

apiVersion: v1
kind: Pod
metadata:
  name: busybox
spec:
  containers:
  - name: busybox
    image: busybox
    commands: ["ash","-c","sleep 3600"]
    envFrom:
    - secretRef:
        name: tls-ingress-secret

After you create the pod, try kubectl exec -it busybox -- env
