  • Going to reinstall.. need ideas.

    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!

    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

    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

    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.
