Organize home server docker containers behind nginx proxy [resolved] - docker

Question

I have a home server I use primarily for self-hosted applications (notes, git server, Jenkins server, etc.) that I'd like to organize so I don't have to remember all the ports for each container. I was hoping to setup a structure as follows:
http://home.server/
http://home.server/jenkins
http://home.server/cowyo
http://home.server/pihole
etc…
I'd like the root endpoint to route to a container running google's cadvisor for monitoring the status of all my containers, /jenkins to route to Jenkins, /pihole to pi-hole, etc.
Here's how I setup my docker-compose and nginx.conf files based on my understanding of the configuration schema:
docker-compose.yml:
version: '3'
services:
webserver:
image: nginx:alpine
container_name: webserver
restart: unless-stopped
tty: true
ports:
- "80:80"
- "443:443"
volumes:
- ./:/var/www
- ./nginx/conf.d/:/etc/nginx/conf.d/
restart: unless-stopped
cadvisor:
image: 'google/cadvisor'
volumes:
- /:/rootfs:ro
- /var/run:/var/run:ro
- /sys:/sys:ro
- /var/lib/docker/:/var/lib/docker:ro
- /dev/disk/:/dev/disk:ro
ports:
- "8090:8090"
pi-hole:
container_name: pihole
image: pihole/pihole:latest
ports:
- "53:53/tcp"
- "53:53/udp"
- "67:67/udp"
- "8070:8070/tcp"
- "4437:4437/tcp"
environment:
TZ: 'America/Chicago'
# WEBPASSWORD: 'set a secure password here or it will be random'
# Volumes store your data between container upgrades
volumes:
- './etc-pihole/:/etc/pihole/'
- './etc-dnsmasq.d/:/etc/dnsmasq.d/'
dns:
- 127.0.0.1
- 1.1.1.1
# Recommended but not required (DHCP needs NET_ADMIN)
# https://github.com/pi-hole/docker-pi-hole#note-on-capabilities
cap_add:
- NET_ADMIN
restart: unless-stopped
cowyo:
image: 'schollz/cowyo'
ports:
- "8050:8050"
volumes:
- './cowyo/data/:/data/'
restart: unless-stopped
jenkins:
image: 'bitnami/jenkins:2'
ports:
- '8080:8080'
- '8443:8443'
- '50000:50000'
volumes:
- 'jenkins_data:/bitnami'
restart: unless-stopped
volumes:
jenkins_data:
driver: local
nginx.conf:
worker_processes 1;
events { worker_connections 1024; }
http {
sendfile on;
upstream docker-cadvisor {
server cadvisor:8090;
}
upstream docker-pihole {
server pi-hole:8070;
}
upstream docker-cowyo {
server cowyo:8050;
}
upstream docker-jenkins {
server jenkins:8080;
}
server {
listen 80;
location / {
proxy_pass http://docker-cadvisor;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
}
server {
listen 80;
location /pihole {
proxy_pass http://docker-pihole;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
}
server {
listen 80;
location /cowyo {
proxy_pass http://docker-cowyo;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
}
server {
listen 80;
location /jenkins {
proxy_pass http://docker-jenkins;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
}
}
Any ideas on what I'm doing wrong? Any help would be appreciated.
Edit: The problem with the way it runs now is that when I go to one of the urls above, I get a "this website can't be reached" error.
Edit2: The problem above was caused by a bad nginx.conf file which was causing the docker container to not start properly. After resolving that, I get a "502 Bad Gateway".
Edit3 [resolution]: My solution was in this stack overflow answer. TLDR is I had to add the line "network_mode: host" to the nginx section in my docker-compose.yml file.

What is the error you are getting ? Tre below config and if you don't get expected result then see respective logs for the error .
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '

I think you should change to
upstream docker-cadvisor {
server 127.0.0.1:8090;
}
upstream docker-pihole {
server 127.0.0.1:8070;
}
upstream docker-cowyo {
server 127.0.0.1:8050;
}
upstream docker-jenkins {
server 127.0.0.1:8080;
}
