This is a simple docker compose based ingress/DNS stack for local dev.

First ensure you have docker and docker compose installed.

To start the network in the background, simply clone this repo and run docker compose up -d.

Once the network has been started you can point your workstation's DNS at 127.0.0.1 which will resolve any *.dev.local domain to the local traefik proxy running as part of this stack.

Other applications can be exposed via this proxy by running their containers on the localdev docker network with the following label:

• "traefik.http.routers.examplefastapi.rule=Host(<APPNAME>.dev.local)"

Where is the name of the service you're exposing. This will route any requests to your workstation on port 80 with the hostname .dev.local to the labeled container, which when combined with the local DNS server, allow host based routing for multiple HTTP containers on the same workstation.

The following docker-compose.yml file can be added to an existing application to run it alongside this localdev networking stack. Replace example-app with the name of the application.
