haproxy-certbot missing logs?

[greg-mcnamara]

I have deployed Thingsboard PE using this docker-compose config. I'm trying to troubleshoot a transport error with MQTT and SSL, and I'd like to check the haproxy logs. I was expecting them at /var/log/haproxy.log (which points to a host volume) but can't find them. I also tried attaching to the container to view the live logs but there's no output. With this docker-compose configuration, are the haproxy logs generated and available? If not by default, would it be possible to adjust the configuration to output the logs to a volume outside the container? I can see the logs are published on 127.0.0.1 on the container, and should be picked up by syslog but not sure where they go from there.

Hi, you can try something like using the log format and option tcplog for tcp , option httplog for http
Feel free to use an official haproxy documentation for fine-tuning your setup.

# log 127.0.0.1 local0
# log 127.0.0.1 local1 notice
 log stdout format raw local0 notice
...
 mode http
 option httplog
...
frontend http-in
 bind *:${HTTP_PORT} alpn h2,http/1.1

 # log http requests
 log stdout format raw local0 info
...
listen mqtt-in
 bind *:${MQTT_PORT}
