Answer 1

Problem is in this part of code

 user: xfs
        command: >
        /bin/sh -c ' sleep 10; 
        wp core install --url="http://localhost:8000" --title="Sample Title" --admin_name=admin --admin_password=admin --admin_email=you@domain.com '

It has to be like this

user: xfs
        command: >
            /bin/sh -c ' sleep 10; 
            wp core install --url="http://localhost:8000" --title="Sample Title" --admin_name=admin --admin_password=admin --admin_email=you@domain.com '

after command: > next 2 lines you need to give 1 Tab.

Answer 2

You can install wordpress Cli either in the compose file. or you can copy the wp cli into the image using dockerfile and install wordpress using custom entrypoint.
