You need to have an SSL certificate for your domain. You could generate it with Certbot.

Fill in the db.env and ssl.env files and the MYSQL_ROOT_PASSWORD environment variable in docker-compose.yml file. The CERT_PATH needs to contain the

• .crt file
• .key file

If you generated your certificate with Certbot you can create symbolic links:

cd /path/to/certs
ln -s /path/to/certs/fullchain1.pem mydomain.crt
ln -s /path/to/certs/privkey1.pem mydomain.key

Replace mydomain with the domain covered by your certificate and used to access your Nextcloud instance.
