Lpar2rrd/Stor2rrd as docker using the same port

margrepko

In the past I installed lpar2rrd and stor2rrd on the same linux OS using "legacy" method - installing rpm, configuring apache etc.

Recently I started lpar2rrd instance as a docker, I forwarded 80 port on host to 80 port on lpar2rrd container. It works fine.

But when I want to use stor2rrd on the same host, 80 port is already in use, therefore I cannot folow "legacy" approach where both applications are simply accessible from the same IP/Port - but suing different url /lpar2rrd and /stor2rrd.

I know I can start stor2rrd container with forwarding different port, but then I need to request extra port to be opened on firewall. Is there a better way of starting both lpar/stor as docker using the same port (80 in my case)?

Thanks!

Hello,

I think the best solution for you will be some proxy server (container) running on port 80/443 and routing traffic between LPAR/STOR containers.

I'll do some testing and prepare brief howto for you.

Hello,

• Create docker-compose.yml like this:

version: "3.7"
services:
 caddy:
  image: caddy:latest
  restart: unless-stopped
  container_name: caddy
  ports:
   - "80:80"
   - "443:443"
  volumes:
   - ./Caddyfile:/etc/caddy/Caddyfile

 lpar2rrd:
  image: xorux/lpar2rrd
  restart: unless-stopped
  container_name: LPAR2RRD
  ports:
   - "8162:8162"
  volumes:
   - lpar2rrd:/home/lpar2rrd

 stor2rrd:
  image: xorux/stor2rrd
  restart: unless-stopped
  container_name: STOR2RRD
  volumes:
   - stor2rrd:/home/stor2rrd

volumes:
 lpar2rrd:
 stor2rrd:

Adjust ports, volumes, names etc. to fit your environment

• In the same dir create Caddyfile like this:

{
        auto_https off
}
 
localhost:80 {
        handle_path /lpar2rrd-cgi/* {
                rewrite * /lpar2rrd-cgi/{path}
                reverse_proxy lpar2rrd:80
        }
        handle_path /lpar2rrd/* {
                reverse_proxy lpar2rrd:80
        }
        handle_path /stor2rrd-cgi/* {
                rewrite * /stor2rrd-cgi/{path}
                reverse_proxy stor2rrd:80
        }
        handle_path /stor2rrd/* {
                reverse_proxy stor2rrd:80
        }
}

When you start all services with docker-compose up -d, you can find both apps running on the same host at following urls:

http://your_hostname/lpar2rrd/

http://your_hostname/stor2rrd/
