Bug: Alpine Dockerfile Issues

[naphelps]

Describe the bug.

1. The base image is version 3.7. This was last updated June 19, 2019.
   

   anax/anax-in-container/Dockerfile.alpine.amd64

   Line 1 in 69bc5f7

   FROM docker.io/alpine:3.7

2. This Dockerfile references microdnf to work with packages, but Alpine Linux uses apk as its package manager.
   

   anax/anax-in-container/Dockerfile.alpine.amd64

   Line 13 in 69bc5f7

   RUN microdnf update -y --nodocs && microdnf clean all && microdnf install --nodocs -y shadow-utils \

3. IBM is the labeled vendor.
   

   anax/anax-in-container/Dockerfile.alpine.amd64
