When to Update

Update Coreflux when a new release includes fixes or features you need. Check Release Notes for what changed in each version.
Project data is preserved. If you installed with the Docker volume mount (project-volume:/etc/project), your LoT, routes, and configuration survive stop/remove and a fresh container start.

​
Docker

To run the latest image, stop and remove the existing container, then start a new one with the same docker run command from Installation. The --pull=always flag ensures Docker fetches the newest latest tag before each start.
Use your actual names. The examples below use the default container name coreflux_broker and volume project-volume. If you chose different names when you first installed, replace them in every command.
1

Stop and remove the container

docker stop coreflux_broker
docker rm coreflux_broker
This stops the broker and removes the container. Named volumes (such as project-volume) are not deleted—your project files remain on disk.
2

Start a new container

Run the same command you used for installation. For the standard setup:
docker run --pull=always -d --name coreflux_broker -p 1883:1883 -p 5000:5000 -p 8080:8080 -p 8443:8443 -v project-volume:/etc/project coreflux/coreflux-mqtt-broker:latest
If you use TLS ports, include the extra mappings from the TLS/SSL accordion on Installation—still with --pull=always, the same container name, and the same project-volume mount.
3

Verify

Open the Coreflux HUB at http://localhost:8080 (or your mapped HTTPS port) and confirm routes and LoT definitions are present. Subscribe to $SYS/Coreflux/Version in the Data Viewer to confirm the broker version.
