Beginning of my Dockerfile is
FROM mcr.microsoft.com/powershell:latest
Now it is version which uses Ubuntu 20.04 with Powershell 7.1.2.
How can I replace “latest” with some tag to freeze image version in future?
How to detect this tag?
I need to continue using Ubuntu 20.04 with Powershell 7.1.2 in Dockerfile when mcr.microsoft.com/powershell:latest will have Ubuntu 21 and Powershell 8 for example.
