Failed To Resolve With FrontEnd DockerFIle.v0

I had the same issue and all I had to do was to capitalize the docker configuration filename

dockerfile > didn't work

Dockerfile > did work

I had this issue while trying to build my container running inside Windows Subsystem for Linux (WSL) and all I had to do was close the terminal and reopen my window and my issue was solved.

In my case I was trying to copy over wp-content from my current directory, inside the docker image I was building. Like so:

FROM wordpress:latest

# Copy wp-content
COPY ./wp-content/ ./var/www/html/wp-content/

However, I noticed that I had a .dockerignore file, which explicitly was told to ignore wp-content.

When I removed wp-content/ from .dockerignore it worked fine.
