How to add a reverse proxy to a docker image - docker

Question

I have a docker image running a metabase website instance, which I access like: <my-ip>:3000, this image is launched with:
docker run -d -p 3000:3000 \
-v /root/metabase_data:/metabase_data \
-e "MB_DB_FILE=/metabase_data/metabase.db" \
--name metabase metabase/metabase
This access is not secure and I'd like to use it via https, I tried using nginx to add a reverse proxy but I could not find a way to turn this port (or any other for that matter) into https.
Is there a better way to do that?

Answer 1

You can do it with nginx
Wrap your command to docker-compose:
version: '3.7'
services:
nginx:
image: nginx:latest
container_name: nginx
volumes:
- ./nginx:/etc/nginx:ro
ports:
- 80:80
- 443:443
- 3000:3000
restart: always
metabase:
image: metabase/matabase:latest
container_name: metabase
environment:
- MB_DB_FILE=/metabase_data/metabase.db
volumes:
- /root/metabase_data:/metabase_data
restart: always
Create SSL certs for nginx
Write conf for nginx
worker_processes 1;
events { worker_connections 1024; }
http {
sendfile on;
upstream metabase {
server metabase:3000;
}
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
server {
listen 3000 ssl;
ssl_certificate /etc/nginx/ssl/ca.crt;
ssl_certificate_key /etc/nginx/ssl/ca.key;
location / {
proxy_pass http://metabase;
proxy_redirect off;
}
}
}
Execute docker-compose up -d
