LAB 7.2 - Section Image caching and build times
It looks like in the LAB 7.2 - Section Image caching and build times some information was omitted prior to starting this.
From reading the output of the first command the Dockerfile used is not the one created just prior to this as it is using a different base image specified in FROM.
Prior the FROM was configured to use alpine and the output seems to be using the official nginx Dockerfile to some extent as it is using the buster-slim base image.
Using the basic Dockerfile created prior to this section will cause the subsequent steps to file with a missing file error for the ln to /var/log/nginx/access.log.
Looking further down the lab there are steps described that are already in the official nginx Dockerfile so that would somewhat negate the reason for having this lab.
Please let me know if there is a basic Dockerfile that needs to be used for this or if this lab needs to be performed on the official nginx Dockerfile.
