Items underlined in red are altered in order to build the image correctly. Image is built successfully from the dockerfile as shown. Where is the problem?
But as per my understanding image name and tag
<none> comes only when image build process is not done successfully.
The command I used to build the image without tagging ( intentionally) is : docker build .
I want to know what is my mistake.
I have attempted this in past and this is what is my output from build. The only difference i noticed is in my Dockerfile i didn’t had ^ symbol for sed and also i have used single quotes. Though that doesn’t makes any difference, the reason is we can see you have successfully built the image. So, now we need to know how the KodeKloud validates this question at their algorithm.

I found a typo mistake in my Dockerfile when copying from my laptop to KK lab
I copied index.html to /usr/local/apache2/conf/htdocs and it should /usr/local/apache2/htdocs
Nice @Devops. Good to hear you found your solution.
