Forgive me if I am asking a stupid question, but I am building a server where I will host multiple Flask websites Docker Container using Nginx Docker. My question now is: is it better to have one main nginx docker container and then host all my Websites Docker containers on it or have an Nginx docker container for each application with docker compose?
I want to know in terms of resource handling and efficiency which one is better to go for ?
@Jacob Following your answer, i am trying to setup something like this
docker-compose.yml:
version: "3.8"
services:
portfolix:
container_name: portfolix
image: mervin16/portfolix:dev
env_file:
- config_local.env
expose:
- 8086
restart: always
networks:
- sky_net
mes:
container_name: mes
image: mervin16/mes:dev
networks:
- sky_net
expose:
- 8085
restart: always
nginx:
build: ./nginx
container_name: nginx
ports:
- "8085:85"
- "8086:86"
restart: always
networks:
- sky_net
networks:
sky_net:
name: sky_network
driver: bridge
Now each website is available on localhost:8085 and localhost:8086
I am then using a reverse proxy on Nginx (not docker but the one installed on my server) to redirect traffic to my domain name:
server {
server_name mes.th3pl4gu3.com;
location / {
access_log /var/log/nginx/mes/access_mes.log;
error_log /var/log/nginx/mes/error_mes.log;
proxy_pass http://localhost:8081;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/mes.th3pl4gu3.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mes.th3pl4gu3.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = mes.th3pl4gu3.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name mes.th3pl4gu3.com;
return 404; # managed by Certbot
}
