  • Hosting Wiki.js behind a jwilder/nginx-proxy
    1 project | /r/selfhosted | 18 May 2023
    Yeah, I usually do if I pass URLs to container. But again, the nginx config is completely auto-generated by docker-gen. Not sure why they don't use the container name, maybe duplicate container names? (if that's possible)
  • Going to reinstall.. need ideas.
    5 projects | /r/selfhosted | 25 Feb 2023
    I've not got around to it, but I've always fancied creating a nice landing page that automatically updates as services come up/down, using the system jwilder created to make nginx-proxy, docker-gen. Could be a fun little project, anyway!

  • Easiest solution for local deployment?
    5 projects | /r/docker | 18 Sep 2022
    Then to make deployment super easy we're using nginx-proxy which uses docker-gen (and the acme-companion for automatic SSL cert generation) to automatically re-configure an nginx reverse proxy to point to your containers.
  • Need help with a flexible configuration for Node and Nginx
    3 projects | /r/node | 14 Sep 2022
    I've now got a setup using docker where the reverse proxy configuration is within the container's configuration (using nginx-proxy, which uses docker-gen). That way I just set the host, path, etc. in my container config, deploy, and the nginx servers are re-configured accordingly. No need to worry about ports and IPs then either.
  • How do you manage and maintain the order of your container ports? It's a bit of a mess on my personal server
    4 projects | /r/selfhosted | 10 Sep 2022
    I use an automated nginx reverse proxy. What this does is setup an nginx reverse proxy which uses docker-gen (follow the advice of setting it up separately). docker-gen listens for docker events such as a container being run, inspects that container for the details it needs (port, host, etc.) then configures the nginx accordingly.

  • Wireguard (docker-compose) has stopped being able to connect to the internet.
    2 projects | /r/WireGuard | 10 Jul 2023
    My hunch is that because I decided to include the acme-companion image in this nginx setup, that maybe it has something to do with the SSL certs? The only other thing I could think of is that I had to combine the networks in order for nginx-proxy and Sonarr both to be able to see my transmission instance via:

    2 projects | /r/nginx | 20 Mar 2023
    I'm experiencing a weird situation, and am not sure how to go about finding a solution. I am running the nginx-proxy container (https://github.com/nginx-proxy/nginx-proxy) together with the acme-companion container (https://github.com/nginx-proxy/acme-companion) to provide https connections to all my different applications under different subdomains on the same host (currently, for testing purposes: only two other nginx containers with a plain html page).
  • What is the correct way to have my webapp in one container and the webserver in another?
    2 projects | /r/docker | 8 Mar 2023
    We use the nginx-proxy docker image with its acme-companion to have an auto configuring SSL reverse proxy, so it's really easy to deploy images (we do it based on a merge PR into protected release branches).
  • adding an SSL cert to a docker container
    1 project | /r/docker | 14 Jan 2023
    Use a reverse proxy to handle TLS/SSL encryption. I find nginx-proxy with companion easy to use, just follow steps 1, 2, 3.

    Where I'm running into issues is with the two stacks I have deployed - one is a wordpress stack which uses the wordpress image along with a db image (going by the docs here), and the other is the nginx-proxy and acme-companion (going by the docs here).
  • dockerfile for httpd

    Just use nginx-proxy and the LetsEncrypt companion as reverse proxy to handle TLS/SSL in front of your web server.

    You can simply use this proxy container which automatically generates nginx config based on envs set in your containers. There is also a companion container which takes care of your certs. https://github.com/nginx-proxy/nginx-proxy https://github.com/nginx-proxy/acme-companion
