How to send requests from nginx & react container to a spring boot container?

}
I have two docker containers, which have the separated front-end and back-end of my application.
In the first container I have already built reactjs code and a nginx web server.
Here is the Dockerfile,
FROM nginx:1.15.2-alpine
COPY ./build /var/www
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
ENTRYPOINT ["nginx","-g","daemon off;"]
This is my nginx.conf file,
worker_processes 1;
events {
worker_connections 1024;
}
http {
server_tokens off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
upstream server {
server 172.20.58.236:8080;
}
upstream client {
server 172.19.59.36;
}
server {
listen 80;
root /var/www;
index index.html index.htm;
add_header 'Access-Control-Allow-Origin' 'http://172.19.59.36';
add_header 'Access-Control-Allow_Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
location /api {
proxy_pass http://server;
}
location ~* .(?:manifest|appcache|html?|xml|json)$ {
expires -1;
}
location / {
try_files $uri $uri/ /index.html;
}
location ~* .(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
expires 1M;
access_log off;
add_header Cache-Control "public";
}
location ~* .(?:css|js)$ {
try_files $uri =404;
expires 1y;
access_log off;
add_header Cache-Control "public";
}
location ~ ^.+..+$ {
try_files $uri =404;
}
location /static/ {
root /var/www;
}
}
}
I referred this & this for the configuration file.
My Dockerfile for the back-end,
FROM openjdk:8-jdk-alpine
ADD target/dependency-graph-service.jar dependency-graph-service.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "./dependency-graph-service.jar"]
Here is a sample route in my Spring Boot back-end,
@CrossOrigin(origins = "*")
@RequestMapping(
value = "/api/greet",
method = RequestMethod.GET
)
public String getHealthCheck(){
String greet = "Get Works!!";
return greet;
}
A typical request from the react front-end would look like,
sendRequest = () => {
axios.get(`http://127.0.0.1/api/greet`)
.then(res => {
console.log(res)
})
.catch(err => {
console.log(err)
})
};
As mentioned ip addresses for my resources are as follows,
client - 172.19.59.36
server - 172.20.58.236
From browser I can talk to the back-end server through client app.
This route works,
http://172.19.59.36/api/greet
A screenshot of the browser
And as expected I can get inside of the container and wget the same url and it works.
A screenshot of the terminal
The problem is when the same request is sent from the react
application or the compiled javascript chunk, I get a CORS error, as
it is generated inside the container I guess. This request does not hit the server.
Screenshot of the error
In the index.html by the script tag I have added a library and browser does not download it as well.
Library in script
404 on the library URL
Please guide me to correct this issue, I tried some nginx configs to resolve the CORS block but nothing worked.
When running the containers port mappings are as follows,
client(172.19.59.36) - 80:80
server(172.20.58.236) - 8080:8080
I referred this as well.
Thanks in advance.
