Getting issue while updating logo in senaite

I have changed the logo from the docker path(home/senaite/senaitelims/src/senaite.core/src/senaite/core/skins/senaite_images#) and uploaded a new image from my local system with the same name, after that I had committed the docker image with the id and a new name, after running the the docker I can not login with the same default username and password which is admin admin
docker name :senaite/senaite:2.x changed to senaite/senaite:3.x
port :8080
