az storage blob sync fails to run in docker image #10381
Description
Describe the bug
Docker image from docker hub seems to be flawed in some way that causes az storage blob sync to fail, the issue does not appear when running the command without docker. Details below.
Command Name
az storage blob sync
Errors:
Azcopy command: ['/root/bin/azcopy', 'sync', 'my-dir', 'https://mytestaccount.blob.core.windows.net/my-container/?se=2019-08-31T12%3A14%3A30Z&sp=rwdlacup&sv=2018-03-28&ss=b&srt=sco&sig=GUi3e6WrUDHGYtBYAgKZVOq2CPyIVbP2PIV4YHQMaek%3D', '--delete-destination', 'true']
The command failed with an unexpected error. Here is the traceback:

To Reproduce:
Run this command with any valid storage account:
docker run --rm -it -e AZURE_STORAGE_CONNECTION_STRING="..." microsoft/azure-cli az storage blob sync --container my-container --source my-dir
Expected Behavior
Proceed without fatal error.
Environment Summary
Linux-5.0.0-20-generic-x86_64-with
Python 3.6.4
Shell: bash
azure-cli 2.0.72
Image: microsoft/azure-cli:latest
Digest: sha256:5510861af13e65ad303c0cfb6dfaaba35385c794e84e4d5c3855aaf6df2eb511
Note: I took me some time to report the issue, I noticed the behavior on latest image some time ago, the cli version was 2.0.67 then (which itself is probably not that relevant, but might point to the Dockerfile version).
Additional remarks
As far as I could investigate the issue, it seems the Alpine distribution, that docker image is based on, is missing some environment components.
Adding line below to the Dockerfile in my case fixed the issue:
RUN apk add --no-cache libc6-compat
