I am new in nginx. I want to rewrite
feature-1234.mydomain.com/xyz?foo=bar
to
docker-feature-1234:9000/xyz?foo=bar
with request parameters.
I use official nginx docker image. How should be my nginx.conf file?
EDIT: 'feature-1234' is a variable so:
feature-5678.mydomain.com
should serve as
docker-feature-5678:9000
By combining answers, i found the solution.

I am running 3 services using docker compose on 3 ports: svc1:8081, svc2:8082, and svc3:8083 respectively. I have nginx installed on my host machine (not as a docker container), I want to reverse proxy all the requests to appropriate services so I am rewriting the url inside the nginx location block and performing a reverse proxy.
I am unable to get the results as something the files are not loading (mainly the static file to docker container)
My nginx config is as follows:
server {
listen 80;
server_name - ;
location /svc1/ {
rewrite ^/svc1(.*)$ $1 break;
proxy_pass http://localhost:8081;
}
location /svc2/ {
rewrite ^/svc2(.*)$ $1 break;
proxy_pass http://localhost:8082;
}
location /svc3/ {
rewrite ^/svc3(.*)$ $1 break;
proxy_pass http://localhost:8083;
}
}
I would be thankful if anyone can point if I am doing any wrong. Thanks in advance for your help.
Try this:
server {
listen 80;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Referer $http_referer;
# Additionally those headers if websocket/reload is used:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
location /svc1/ {
proxy_pass http://localhost:8081/;
}
location /svc2/ {
proxy_pass http://localhost:8082/;
}
location /svc3/ {
proxy_pass http://localhost:8083/;
}
}
Don't forget to restart nginx after changing conf!
I have a Flask API and a Swagger UI generated with Flask Restplus. The API runs in a Docker container behind an Nginx container which serves it over HTTP.
Here is a health check endpoint which confirms the API is running:https://mobydq.net/mobydq/api/v1/health
{"message":"MobyDQ API running in production mode"}
However, the Swagger which is supposed to load at the following URL does not load at all: https://mobydq.net/mobydq/api/doc
Here is the Nginx configuration:
http {
upstream api {
server api:5434;
}
upstream app {
server app:3000;
}
# Server for https
server {
listen 443 ssl http2;
server_name mobydq.net;
ssl_certificate /etc/letsencrypt/live/mobydq.net/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mobydq.net/privkey.pem;
# Location for MobyDQ Flask API
location /mobydq {
limit_req zone=default burst=20;
proxy_pass http://api;
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-Proto $scheme;
}
# Location for MobyDQ Web App
location / {
limit_req zone=default burst=20;
proxy_pass http://app;
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-Proto $scheme;
}
}
# Default server to redirect http requests to https
server {
listen 80 default_server;
server_name mobydq.net;
listen [::]:80 default_server;
location ~ /.well-known {
root /var/www/letsencrypt;
}
location / {
return 301 https://$host$request_uri;
}
}
}
Any idea why the Swagger is not loading? I looked into the http requests sent when loading the page but it did not help much. I can only see the favicon loading:
I also looked at the console and saw an error but I'm not able to tell what it means:
The problem was that Nginx did not properly redirect the http requests when trying to get the resources from Swagger (the JSON configuration file in particular).
The issue has been fixed by changing the Nginx configuration as follow:
[...]
# Location for MobyDQ Flask API
location ~ ^/(mobydq|swaggerui) {
limit_req zone=default burst=20;
proxy_pass http://api;
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-Proto $scheme;
}
[...]
I would like to implement a reverse proxy which redirect request of http://www.dummy.com/foo/bar/test to http://127.0.0.1/hello/world. I have tried to add rewrite before the pass and it seems not working ...
server {
listen 80;
listen [::]:80;
server_name www.dummy.com;
# access_log /var/log/nginx/upstream_log.log
location / {
root /usr/share/nginx/html/dummy;
}
location /foo/bar/test {
rewrite ^/foo/bar/test /hello/world break;
proxy_pass http://127.0.0.1/;
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-Proto $scheme;
access_log /var/log/nginx/upstream_log.log upstream_logging;
}
}
Is there something missing or wrongly configured?
The above config works as expected... The other server was misconfigured when I test the above configuration.
I've installed a sonarqube and a Jenkins server in one machine, with ports 9000 and 8080 respectively. I'd like to make urls like test_hub.mysite.com/sonar and /jenkins and redirect to machine and port correctly, but maintaining original address test_hub.mysite.com/sonar.
My configuration with nginx is pretty simple:
server {
listen 80;
server_name sonar.mysite.com;
location /sonar/ {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://52.29.xx.xx:9000;
}
}
server {
listen 80;
server_name test_hub.mysite.com;
location / {
# you can use regular exp also
if ($request_uri = /sonar) {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://52.29.xx.xx:9000;
}
if ($request_uri = /jenkins) {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://52.29.xx.xx:8000;
}
}
}

Is it possible to pass requests for a specific path to a different upstream server?
Here is my nginx site configuration:
upstream example.org {
server 127.0.0.1:8070;
keepalive 8;
}
server {
listen 0.0.0.0:80;
server_name example.org www.example.org;
access_log /var/log/nginx/example.org.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://example.org;
proxy_redirect off;
}
}
Currently, requests to this site are redirected to a Node.js instance running on port 8070.
I would like requests to this site that have a path starting with /services to be redirected to another Node.js instance running on port 8080.
Is this possible? And of course -- how so?
Yes, just add another location block:
upstream example.org {
server 127.0.0.1:8070;
keepalive 8;
}
upstream other.example.org {
server 127.0.0.1:8080;
keepalive 8;
}
server {
listen 0.0.0.0:80;
server_name example.org www.example.org;
access_log /var/log/nginx/example.org.log;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_redirect off;
location / {
proxy_pass http://example.org;
}
location /services {
proxy_pass http://other.example.org;
}
}
Note: I extracted all shared proxy directives into the server block so that they are not repeated in each location block. If they would differ between different locations, you would have to move them again into the location blocks...
