Docker image: SSH command is gone

[inno-steffg]

Describe the bug

Former versions of the "standard" docker image (mcr.microsoft.com/azure-cli:latest) contained ssh command (formerly provided by installed openssh package).

This is no longer the case for version 2.54.0 build at 2023-11-08T05:17:55Z.

./usr/share/bash-completion/completions/ssh

Having the ssh command within the container allowed to forward ports using a combination of Azure bastion and Azure virtual linux machine.

From the Azure CLI documentation, which shows how to map local SSH keys into the container, I concluded, that ssh is a part of the image.

Related command

docker run --rm -it mcr.microsoft.com/azure-cli sh -c "az extension add -n ssh && az login --use-device-code && az ssh vm --ip azureVm"

Errors

Failed to run ssh command with error: [Errno 2] No such file or directory: 'ssh'.
Ensure OpenSSH is installed correctly.
Alternatively, use --ssh-client-folder to provide OpenSSH folder path.

Hi @inno-steffg
Find similar issue #22084.

Issue title	az ssh vm failure
Create time	2022-04-16

Possible solution:
The issue is that the ssh command is no longer available in the latest version of the "standard" docker image (mcr.microsoft.com/azure-cli:latest). This command was previously provided by the installed openssh package. The ssh command within the container allowed to forward ports using a combination of Azure bastion and Azure virtual linux machine.

One solution to this issue is to update the ssh extension to version 1.1.1. Another solution is to install OpenSSH on your box and then create a PATH environment variable and use a new cmd session to run the same CLI command. You can also specify flag --ssh-client-folder with c:\windows\sysnative\openssh or set c:\windows\sysnative\openssh to the PATH environment variable.
