I want to containerize my web applications. Currently, I am using Apache to provide a couple of PHP apps.
Every app should be provided by their own container. Nginx should be reachable by port 80/443. Depending on the sub route it should proxying to one of the containers.
For example:
www.url.de/hello1 --> hello1:80
www.url.de/hello2 --> hello2:80
docker-compose.yml:
version: '3'
services:
nginx:
image: nginx:latest
container_name: reverse_proxy
volumes:
- ./nginx.conf:/etc/nginx/nginx.conf
ports:
- "80:80"
- "443:443"
networks:
- app-network
depends_on:
- hello1
- hello2
hello1:
build: ./test1
image: hello1
container_name: hello1
expose:
- "80"
networks:
- app-network
hello2:
build: ./test2
image: hello2
container_name: hello2
expose:
- "80"
networks:
- app-network
networks:
app-network:
nginx.conf:
events {
}
http {
error_log /etc/nginx/error_log.log warn;
client_max_body_size 20m;
proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;
server {
server_name wudio.de;
location / {
proxy_pass http://hello1:80;
}
location /hello1/ {
proxy_pass http://hello1:80;
rewrite ^/hello1(.*)$ $1 break;
}
location /hello2/ {
proxy_pass http://hello2:80;
rewrite ^/hello2(.*)$ $1 break;
}
}
}
If I run docker-compose up -d, only the container with image webapp-test1 is online. And I also can reach it by curl localhost:8081.
Nginx is not running. If I remove the line in which I add nginx.conf to the volume of Nginx, it´s working.
What I´m doing wrong?
Edit1:
http:// was missing. But proxying still not working on subroutes. Only location / is working. How I get /hell1 running?
Note the proxy_pass statement. You have to mention the protocol in that statement. Also note how you can refer to the name of the service in your docker-compose.yml file (in this case hello1).
events {
}
http {
error_log /etc/nginx/error_log.log warn;
client_max_body_size 20m;
proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;
server {
listen 80;
location / {
try_files $uri @proxy ;
}
location @proxy {
proxy_pass http://hello1:80/;
}
}
}
Edit: Try this instead
events {
}
http {
error_log /etc/nginx/error_log.log warn;
client_max_body_size 20m;
proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;
server {
listen 80;
location / {
try_files $uri @proxy ;
}
location @proxy {
if ($request_uri ~* "^\/hello1(\/.*)$") {
set $url "http://hello1:80$1";
}
if ($request_uri ~* "^\/hello2(\/.*)$") {
set $url "http://hello2:80$1";
}
proxy_pass "$url"
}
}
}
