Generate load for nginx load balancer

Hi, I’ve been following this tutorial Load Balancing with NGINX and I’ve used the same job configurations provided there. I wanted to verify if it is working by generating load on the demo-webapp. I’ve already tried using hey but it doesn’t seem to work.

I’d also like to mention that I have encountered this issue on nginx:

10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf is not a file or does not exist

I saw somewhere that I should remove the volumes block :

volumes = [
  "local:/etc/nginx/conf.d",
]

Though I’m not sure if this is the correct solution for this issue but, these are the logs that I get instead:

10-listen-on-ipv6-by-default.sh: info: Getting the checksum of /etc/nginx/conf.d/default.conf
10-listen-on-ipv6-by-default.sh: info: Enabled listen on IPv6 in /etc/nginx/conf.d/default.conf

Are these the expected logs then rather the one that I’m getting before?
