betterde/cdns:latest serve
Docker Compose
In this example, I use Smallstep CA as the ACME Challenge Provider, To learn more about Smallstep CA, visit their official website.
wget -O docker-compose.yaml https://raw.githubusercontent.com/betterde/cdns/master/docker-compose.yaml
docker compose up -d step
docker exec -it -u root step-ca bash -c "step certificate install -all /home/step/certs/root_ca.crt"
docker compose up -d
