Install with Docker

Run Hub in your browser on Linux, Windows or macOS.

Before you start, install Docker and make sure it is running. These commands work in PowerShell, macOS Terminal or a Linux shell.

Start Hub with Docker
PowerShell or terminal
docker run -d --name coreflux-hub --restart unless-stopped -p 8080:3000 -v coreflux-hub-data:/opt/coreflux-hub/data coreflux/coreflux-hub:latest
Check that it is running (look for “Up”)
docker ps --filter name=coreflux-hub
Open Hub and connect to your broker
http://localhost:8080
Use the address of the computer running Docker if it is on another machine.
To connect to a broker on the Docker host, use host.docker.internal on Docker Desktop, or the host’s network address on Linux. Enter MQTT port 1883 and your broker credentials. In the Docker version of Hub, localhost refers to its own container.
