build alpine base image

[bjrb20]

Could you push an alpine base image version?

Then you could support more complex commands like this:

grpcurl -plaintext \
             -H "Authorization: Bearer $$(cat /var/run/secrets/tokens/vault-token)" \
             localhost:80 \
             example.v1.Service/Func

This works with a common auth pattern on kubernetes where auth tokens are mounted into a volume on a pod.

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
  - image: nginx
    name: nginx
    volumeMounts:
    - mountPath: /var/run/secrets/tokens
      name: vault-token
  serviceAccountName: build-robot
  volumes:
  - name: vault-token
    projected:
      sources:
      - serviceAccountToken:
          path: vault-token
          expirationSeconds: 7200
          audience: vault

seems reasonable to me
