Hi @shaarohi16

It is not working because you have not configured apache2 to listen on the given port (8087 in this case, but if you do the task again, it might be different.

Yes, you have to EXPOSE it, but that’s not enough. apache2 is listening on port 80 unless you update its configuration files, as per How To Change Port Number in Apache in Ubuntu - Ubiq BI

Now since this is a dockerfile, you can’t do it manually using vi. You have to use sed to change the port number in the two files indicated in the above documentation.

When it is correctly configured, the curl test will return a mass of HTML
