App service SSH problem - sshd: no hostkeys available -- exiting.

Question

Posting on behalf of a customer who keeps experiencing errors when trying to post.*

I have issues getting SSH to work in my App-service.

I've followed this tutorial:
https://learn.microsoft.com/en-us/azure/app-service/configure-custom-container?pivots=container-linux#enable-ssh

Unable to post details of the docker file and ssh config as I keep getting an error. Full details can be found here though:

@Tony ,

In your dockerfile, I don't see where you copied your ssh_setup.sh script file. You're copying the existing (base image) file to /tmp. You create this file and copy it during docker build.
