How to correctly setup sub-domains with ssl and nginx as a proxy?

I managed to configure nginx reverse proxys and ssl in order to run a Directus 9 Docker installation.

But my actual goal is to run 3 separate Directus 9 Docker installations on 3 subdomains (like “”). The sub-domains open the proper index sites (from their defined subfolders) as long as there is no proxy_pass defined (in the nginx block configuration):


server {
    root /var/www/;
    index index.html index.htm index.nginx-debian.html;
    location / {
        try_files $uri $uri/ =404;

As soon as proxy_pass is active, the subdomain does not open properly; and the running terminal on the main domain (the one with the working Directus installation) detects something and prints to the console.

Also, when running docker-compose, this command seems to influence all instances! A docker-compose down stops all docker instances. How can I execute docker containers in each subdomain separately?

Hi there,

Is your Nginx service also running inside a Docker container? If this is the case, you would need to update this line here:

# proxy_pass;

And change the IP with the container name of the backend service that you are using.

Feel free to share more details about your setup, like your Docker compose file so I could advise you further.
