For public communication, must be accessible to users
sudo docker run -p 6000:80 -d --name biomaj-public-proxy -e --link biomaj-consul:biomaj-consul -v PATH_TO/nginx-public.ctmpl:/nginx.ctmpl:ro biomaj-proxy
For internal communication, must be accessible to services only
sudo docker run -p 5000:80 -d --name biomaj-proxy -e --link biomaj-consul:biomaj-consul -v PATH_TO/nginx.ctmpl:/nginx.ctmpl:ro biomaj-proxy
To test generation, once, of the template (you need consul-template)
./consul-template -consul 127.0.0.1:8500 -template nginx.ctmpl:/tmp/nginx.conf -once
cat /tmp/nginx.conf
you need a consul instance (or a cluster)
sudo docker run --name biomaj-consul --rm -p 8400:8400 -p 8500:8500 -p 8600:53/udp -h node1 progrium/consul -server -bootstrap -advertise IP_OF_NODE -ui-dir /ui
and biomaj services need to declare consul host in their config.yml
To test if registration if fine, connect to consul ui or test with dig
$ dig @IP_Of_CONSUL_NODE -p 8600 biomaj_download.service.dc1.consul. SRV
Example output:
; <<>> DiG 9.10.3-P4-Ubuntu <<>> @131.254.17.40 -p 8600 biomaj_download.service.dc1.consul. SRV
