I'm new to the nginx and I have to configure a reverse proxy for application which is hosted in individual docker containers
Ex: 1. Home page - Container A
2. Dashboard - Container B
3. Admin Panel - Container C
This solution has only one URL and all containers are hosted in a single VM with Nginx reverse proxy as below.
Diagram
The home page has a login button. After the user login the dashboard will load (The dashboard URL is dynamic)
after login, user can navigate to the other modules (ex. admin panel)
I need to configure Nginx reverse proxy for these frontend docker containers to achive below pointes.
Hide the home page port from the URL
abc.example.com ---> abc.example.com:5022 Home page
this step has configured
server {
listen 80 default_server;
listen [::]:80 default_server;
root /mnt/disk2/wwwroot;
index index.html index.htm index.nginx-debian.html;
server_name abc.example.com;
location / {
proxy_pass http://abc.example.com:5022/;
proxy_redirect http://abc.example.com:5022/ /;
}
After login I need to hide the dashboard port from the URL
Still. I couldn't find a way for this step
Hide all docker ports from the application url abc.example.com.
Still. I couldn't find a way for this step
Is there any one has done this before?

I'm running php+nginx api inside docker container. It is available on port 8080. I trying to add nginx reverse proxy to open api on address api.versite.online and frontend project on versite.online.
I installed nginx on server, added /etc/nginx/sites-available/api.versite.online config (also added symlink to sites-enabled directory), tested config with nginx -t, restarted nginx service with systemctl reload nginx, but it had no effect. api.versite.online:8080 and versite.online:8080 makes request to docker container, looks like top level nginx are ignored.
Nginx access log is empty.
/etc/nginx/sites-available/api.versite.online config
server {
listen 80;
server_name api.versite.online;
access_log /var/log/nginx/api.versite.access.log;
location / {
proxy_pass http://localhost:8080;
}
}
It seems that i forgot to add a firewall rule with sudo ufw allow 'Nginx HTTP'
recently I'm trying to set up a litte Home Server with a buildin DNS.
The DNS Service is given by lancacheDNS and set up in combination with a Monolithic-Cache (Port 1234) in two docker containers on 192.168.178.11 (Host machine) in my local network.
Since I want to serve a Website(Port 8080) along with some independent APIs (Ports 8081, 8082 or whatsoever) I decided to use Nginx as a reverse Proxy.
The DNS does the following:
getr.me --> 192.168.178.11
The routing works completely fine and getr.me:8080 gives me my website as expected.
Now the tricky part (for me);
Set up Nginx such that:
website.getr.me --> serving website
api1.getr.me --> serving the API1
api2.getr.me --> serving the API2
For that I created a Newtwork "default_dash_nginx".
I edited the nginx to connect to that via:
networks: default: name: default_dash_nginx external: true
Also I connected my website serving container (dashboard) to the network via --network default_dash_nginx.
The serving website gets the IP 172.20.0.4 (received via docker inspect default_dash_nginx) and also the nginx server is connected to the network.
Nginx works and I can edit the admin page.
But unfortunaly event though I edited the proxyHost to the IP + Port of my website receiced from the network, the site is not available. Here the output of my network inspection: https://pastebin.com/jsuPZpqQ
I hope you have another Idea,
thanks in advance,
Maxi
Edit:
The nginx container is actually a NginxReverseProxyManager Container (I don´t know of it was unclear above or simply not important)
The Nginx container can actually Ping the website container ang also get the HTML files from Port 80 from it.
So it seems like the nginx itself isn´t working like it should.
The first answer got no results( I tried to save it as every of the mentioned files
here
Do I have missed something or am I just not smart enough?
nginx config, try and understand
server {
listen 80;
server_name api1.getr.me;
location / {
proxy_pass http://localhost:8081;
}
}
server {
listen 80;
server_name api2.getr.me;
location / {
proxy_pass http://localhost:8082;
}
}
server {
listen 80;
server_name some.getr.me;
location / {
proxy_pass http://localhost:XXXX;
}
}
The following i want to achieve:
On Server A there is docker installed. There are, lets say, 3 Containers:
Container 1: App1, ip: 172.17.0.2, network: mynet, Simple HTML Welcome page, accessible by port 80
Container 2: App2, ip: 172.17.0.3, network: mynet, a Wiki System -> dokuwiki, accessible by port 8080
Container 3: App3, ip: 172.17.0.4, network: mynet, something else
You can see, every container are in the same Docker network. The Containers are accessible by different Ports.
The Clients on the same network needs to access all of the Containers. I can't use DNS in this case (Reverse Proxy via VHOST), because i am not control the DNS. My Goal:
Container 1 : accessible via http://myserver.home.local/app1/
Container 2 : accessible via http://myserver.home.local/app2/
Container 3 : accessible via http://myserver.home.local/app3/
What i did to solve this is the following: Add another Container with nginx, and do proxy_pass to the containers. I use the official nginx image (docker pull nginx), then i mount my custom config into the /etc/nginx/conf.d dir. My Config looks like the follow:
server {
location / {
root /usr/share/nginx/html;
index: index.html index.htm;
}
location /app1/ {
proxy_pass http://app1/
}
location /app2/ {
proxy_pass http://app2:8080/
}
location /app3/ {
proxy_pass http://app3/
}
}
The app1 does work. The app2 does not: It prints me some ugly html output. In the Browser Web Console, i see a lot of 404. I guess that has something to do with Reverse / Rewrite of nginx, because, the app2 is Dokuwiki. I also add the apache ProxyPassReverse equivalent for nginx, without success.
I just do not know what to do in this case, or where to start. How can i know, what to be rewrite? I hope someone can help me.
As mentioned in the comments:
As soon as I use the dokuwiki basedir / baseurl config, the proxy is working as expected. To do so, edit the dokuwiki.php configuration file located in the conf folder:
conf/dokuwiki.php
change the following settings to your environment
$conf['basedir'] = '/dokuwiki';
$conf['baseurl'] = '';
My application is divided into a backend and frontend docker container which are running in digital ocean server. I purchased a domain and inserted the routes provided from digital ocean into my namecheap DNS. I am using nginx server block to route my frontend to the server and would like it to communicate to my backend docker container. I am currently watching this tutorial from faraday.
My frontend container is running on localhost:3000 and my backend is running on localhost:5000;
And i've set the ports to run when the location is server_name/ . How will my nginx server block know whether it's loading the frontend or backend to the domain since both are expected to run proxy_pass at location /?
I want to display the front onto server_name provided but still able to access my backend
server{
server_name newlife.life;
access_log /var/log/nginx/st-access.log
error_log /var/log/nginx/st-error.log debug
location / {
proxy_pass http://localhost:3000;
}
location / {
proxy_pass http://localhost:5000;
}
}
Your frontend can make the backend calls on a different subpath. These requests will arrive at nginx and then nginx can proxy them to backend by rewriting the URL using the http_rewrite module.
See https://nginx.org/en/docs/http/ngx_http_rewrite_module.html
Example:
location /backend {
proxy_pass localhost:5000;
rewrite ^/backend/(.*) /$1 break;
}
I have an application running on port 4343. This is a single page app, so hitting http://myApp:4343 will dynamically redirect me to somewhere like http://myApp:4343/#/pageOne.
Both the nginx container and the myApp container are running on the same docker network so can resolve via container name.
I'm trying to proxy this via nginx with:
server {
listen 80;
server_name localhost;
location /myApp {
proxy_pass http://myApp:4343
}
}
How do I wildcard the rule?
