You need two such containers and a reverse proxy in front. Copy app.yml to app2.yml and edit it. Running other websites on the same machine as Discourse or perhaps Multisite Configuration with Let’s Encrypt and no reverse proxy if they can have the same plugins and mail server.

[image] DursunCan: Is it possible to make this method via docker? Yes. You’ll have a docker image for each forum. The external reverse proxy can be a docker container too. [image] DursunCan: Does installing a nginx server outside of docker affect performance? Not much.

I installed Nginx. I made my settings. I edited the app.yml file. rebuild process fails.

I used the 1st method on lemp servers. Is it possible to make this method via docker? Does installing a nginx server outside of docker affect performance?
