bitnami/nginx - stop generating RSA key pair

Please is there a way to stop bitnami/nginx to generate RSA key pair on start (since I am not using SSL in nginx.conf)?

It takes 25-30 seconds to start the app :(

Thanks

Based on their README you can just store these certificates persistently:

docker run --name nginx \
  -v /path/to/my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro \
  -v /path/to/nginx-persistence/certs:/certs \
  bitnami/nginx:latest

Try it out. I've found this here.
