Maybe this is useful for others too until there is proper access control in the dashboard.
I make my dashboard accessible with the following docker command:
docker run --rm --publish PUBLIC_IP:14002:14002 --link STORAGE_CONTAINER_NAME alpine/socat tcp-listen:14002,fork,reuseaddr tcp-connect:STORAGE_CONTAINER_NAME:14002
PUBLIC_IP with your server ip or omit it including the colon ‘:’ to publish on all network interfaces. When you stop the container with CTRL+c the port is closed again.
STORAGE_CONTAINER_NAME should be replaced with
storagenode if you followed the documentation, otherwise the name you chose for the container.
