ImageExists in build script always returns true

[karlstav]

hi,

I was trying to build the docker container and it just didn't start. Figured out this would return true even though I did not have the image:

PS C:\Users\Karl> docker images shader-playground-build-image
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

this would again produce an error:

PS C:\x\shader-playground> .\build-docker.ps1
Building docker container...
Unable to find image 'shader-playground-build-image:latest' locally
Error response from daemon: pull access denied for shader-playground-build-image, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
