I'm trying to set up a microservices architecture for a personal blog.
The idea is to have an NGINX container serving up a static gatsby site, and to redirect to other services. For example, I'd like to have a react app at /todos, and an api for that todo app at /todos_api.
My current folder structure is like this:
My docker-compose file looks like this:
version: "3"
services:
gatsby:
restart: always
build:
dockerfile: Dockerfile
context: ./gatsby_blog
ports:
- "80:80"
todoclient:
build:
dockerfile: Dockerfile
context: ./portfolio/todos/todo_client
My main Gatsby nginx file looks like this:
upstream todoclient {
server todoclient:3000;
}
server {
listen 80;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location /todos {
rewrite /todos/(.*) /$1 break;
proxy_pass http://todoclient;
}
}
and my React nginx config is like this:
server {
listen 3000;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
}
The issue I'm pretty certain is with my nginx configs. When I go to localhost I'm met with the gatsby app, but if I go to /todos I get an nginx error. I can see that the request is passed on to the todoclient container correctly, but the error returned is:
open() "/usr/share/nginx/html/todos" failed (2: No such file or directory
If anyone can see where I'm going wrong with the nginx configs I'd really appreciate it. I can post my Dockerfiles too if needed. Thanks
I've managed to get the proxy working now, but the issue is that the todos app cant find its static files. They're in the correct place in the container, and the container works in isolation, so the issue is to do with docker-compose and the nginx proxying.
Done it for angular. The nginx file should replace the file in /etc/nginx/nginx.conf. And place the todos folder - assuming that has the static pages - in /usr/share/nginx/html. You can try one service at a time
http {
server {
listen 80;
server_name localhost;
root /usr/share/nginx/html;
include /etc/nginx/mime.types;
location /todos {
alias /usr/share/nginx/html/todos/;
absolute_redirect off;
rewrite ^(.+)/todos/+$ $1 permanent;
rewrite ^(.+)/todos/index.html$ $1 permanent;
try_files $uri$args $uri$args/ $uri/ /todos/index.html;
}
}
}
