Docker-Compose / Docker Run Example or Instructions

[markschechter]

Hey dude, first of all, thank you for creating this awesome project!

Second, I've been trying to get this project to work for a few days now & I can't for the life of me figure it out. I'm not a total noob when it comes to Docker but I definitely wouldn't call myself an expert.

I know it would be very helpful for me & probably others if you could please provide an example/instructions or maybe a link to another project for reference. I just really want to get this exporter to work with Grafana / Prometheus & I've been driving myself nuts. I'd be very grateful & happy to do anything I can to help support! Thank you!

I figured out my initial problem with regards to the docker-compose layout, but I have a new issue which I'd say is related.

When I run the container, I'm getting the following errors. I feel like I've tried every variation but still no luck. I was getting an SSL error in the logs when using docker-compose. I set up a config.yml file.

docker-compose.yml - I left the comments that I used in testing.
version: '3.7' 
services: 
  plex-exporter: 
    image: granra/plex_exporter 
    container_name: 'plex-exporter' 
    restart: unless-stopped 
    command: 
#      - "--help" 
      - "--config-path=./config.yml" 
#      - "--plex-server=https://MY-IP:32400" 
#      - "--listen-address=9594" 
#      - "--token=TOKEN" 
#      - "--auto-discover" 
    ports: 
      - "9594:9594"

If I uncomment the configs above & not use the config.yml file, I get the following erro:

plex-exporter  | time="2022-03-03T02:40:07Z" level=error msg="Could not add server https://MY-IP:32400: Get \"https://MY-IP:32400/media/providers\": x509: cannot validate certificate for MY-IP because it doesn't contain any IP SANs" context=client
plex-exporter  | time="2022-03-03T02:40:07Z" level=info msg="Found 1 working servers" context=client
plex-exporter  | time="2022-03-03T02:40:07Z" level=info msg="Beginning to serve on port 9594"
plex-exporter  | time="2022-03-03T02:40:07Z" level=fatal msg="listen tcp: address 9594: missing port in address"

Config.yml:
address: ":9594"\ 
logLevel: "info" \
logFormat: "text"
autoDiscover: true 
token: "TOKEN" 
servers: 
- baseUrl: https://MY-IP:32400 
  insecure: false 
  token: "TOKEN" 

I get the following in the logs:

plex-exporter  | time="2022-03-03T02:32:39Z" level=info msg="Found 0 working servers" context=client
plex-exporter  | time="2022-03-03T02:32:39Z" level=info msg="Beginning to serve on port :9594"

I've figured out that localhost & 127.0.0.1 doesn't work. Any insight would greatly be appreciated.

UPDATE: it looks like my problem was using https. Changed the URL to http & I'm getting the following:

time="2022-03-03T03:05:20Z" level=info msg="Found 1 working servers" context=client
time="2022-03-03T03:05:20Z" level=info msg="Beginning to serve on port :9594"
time="2022-03-03T03:05:54Z" level=info msg="Found 1 working servers" context=client
time="2022-03-03T03:05:54Z" level=info msg="Beginning to serve on port :9594"

I'm not 100% sure if its working yet, but I suppose I'll get there. I hope this thread helps someone!

Sorry for the spam. Now I get

curl http://MY-IP:9594
404 page not found

Not sure how to proceed at this point.

My code so far is:

version: '3.7'

services:
  plex-exporter:
    image: granra/plex_exporter
    container_name: 'plex-exporter'
    restart: unless-stopped
    command:
      - "--plex-server=http://MY-IP:32400"
      - "--token=TOKEN"
    ports:
      - "9594:9594"

[markschechter]

I'm not sure if it's intended behavior BUT, I'm getting metrics in Grafana & they seem to be accurate. Again, hope this thread helps someone out there!

Walking through your struggles helped me a lot! Can you share a bit about how your Plex instance is networked in compose?

I have a sorta complex networking configuration and my exporter instance can't find the Plex server. I would love to see your config as reference.

I was able to get mine working with this configuration:
