Okay it may look stupid but actually these are pretty useful. I use one of these almost every day and often many times a day to experiment with NGINX configuration. There are currently two versions:
- The quick one is useful for simple tests and sharing. There's only one file that defines both the application and config, so you can write short snippets and share them with copy-paste via email or messengers.
- The long one is for something complex. The config files are mounted inside the container. Config changes are constantly checked by the startup script with automatic reload on successful configuration test.
If you're going to use one of these to proxy requests to an application on your host machine:
-
Docker Desktop for Windows or MacOS:
- use
host.docker.internalinstead oflocalhostin NGINX config to refer to docker host. - your app should accept connections from any IP
0.0.0.0and if there's a list of hosts (allowed headers), thenhost.docker.internalmust be in it as well.
- use
-
On Linux you may just enable
network_mode: hostand it'll work as if it's running on the host (i.e. you can uselocalhostfor upstream address).
