I understand this. I try build my image differently, with
python3.6 -m pip install certbot-nginx
and the error changed
The nginx plugin is not working; there may be problems with your existing configuration.
The error was: NoInstallationError("Could not find a usable 'nginx' binary. Ensure nginx exists, the binary is executable, and your PATH is set correctly.")
I found this topic there advise use --webroot
and I so wanted everything to be done for me
