Azure Container Instances 

Are you talking about in the Azure Portal for the ACI instance via SSH?

@@Atmosera- , Thanks for your response. I'm now able to connect to the instance thru the Portal. But I, also, need to connect to the ACI thru PowerShell on VSC.

@@AyanMullick Check out the Azure CLI with Container Exec docs.microsoft.com/en-us/cli/azure/container?view=azure-cli-latest#az-container-exec

@@Atmosera- , I'm looking for an interactive PowerShell session. More like Enter-PSSession . An interactive PowerShell session thru Visual Studio Code.

@@AyanMullick You'd need PS in the container then if I'm understanding you right, which requires windows. Otherwise, you need to use whatever the scripting environment in the the container is.
