You can easily run pwgen with the publicly available docker image.
Because this is a password generator only HTTPS is supported and a TLS certificate and key must be provided.
Example with latest public image:
docker run -v $(pwd):/certs -e CERT_FILE=/certs/cert.pem -e KEY_FILE=/certs/key.unencrypted.pem domano/pwgen
go run cmd/pwgen/main.go
