I just clicked ‘Quick Start Guide’ from the Docker Icon menu (I’m on a Macbook Pro, 10.15.7). Then there are a few ready made CLI commands one can click.
Just redid that and the second step downloads and installs a lot of stuff.
The third step is this:
docker run -d -p 80:80 --name docker-tutorial docker101tutorial
Today I got a different error, one that I can understand:
docker: Error response from daemon: Ports are not available: listen tcp 0.0.0.0:80: bind: address already in use.
I know that port is occupied because when I installed magento 2 I had to choose a different port.
I presume I could do that now but I cannot fathom out why port 80 is in use. I don’t have sharing turned on so the OS Apache should not be running.
Anyway, I need to choose another port. No, won’t let me change that port. I have to stop that image and start again to change the port. I give up.
Yesterday’s error was meaningless to me which is why I posted the issue.
Thank you for your quick response and apologies for the delay in replying,
