Enable gzip with docker and bitnami/nginx - docker

Question

I deployed a website with docker and bitnami/nginx as image: https://www.10studio.tech/demo. After deployment, I realized that files like analyzejs.js was not gzipped:
Here is docker-compose.yml:
version: "3"
services:
docusaurus:
image: bitnami/nginx:1.16
restart: always
volumes:
- ./build:/app
- ./certs:/certs:ro
- ./my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro
ports:
- "3001:3001"
- "3002:3002"
Here is my_server_block.conf:
server {
listen 3002;
absolute_redirect off;
root /app;
location = / {
rewrite ^(.*)$ https://$http_host/docs/introduction redirect;
}
location / {
try_files $uri $uri/ =404;
}
}
server {
listen 3001 ssl;
ssl_certificate /certs/server.crt;
ssl_certificate_key /certs/server.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location / {
proxy_pass http://localhost:3002;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Ssl on;
}
}
Here is /opt/bitnami/nginx/conf/nginx.conf, where gzip seems to be enabled:

include "/opt/bitnami/nginx/conf/server_blocks/*.conf";
# HTTP Server

# port to listen on. Can also be set to an IP:PORT
listen 8080;
location /status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}
}
Does anyone know what's wrong here and how I could enable gzip?

I also just stumbled over the same problem. It seems like the docker image already has gzip enabled. I also have an nginx deployed for the whole server which acts as reverse proxy for the different docker container in the server. What worked for me is to also enabled gzip in the global nginx configuration /etc/nginx/nginx.conf.
Don't know if you also have a wrapping nginx. Hope this helps.
