Changing Dozzle's Hostname

Dozzle's default connection is called localhost. Using the --hostname flag, Dozzle's name can be changed to anything. This value will be shown on the page title and under the Dozzle logo.

Changing the label for localhost also changes the label for the localhost connection which is displayed under the multi-host menu. Below is an example of using --hostname to change the name of Dozzle's subheader to mywebsite.xyz.

sh

docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8080:8080 amir20/dozzle --hostname mywebsite.xyz

docker-compose.yml

services:
  dozzle:
    image: amir20/dozzle:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 8080:8080
    environment:
      DOZZLE_HOSTNAME: mywebsite.xyz

Multi-Host and Agents

--hostname only relabels the host running this Dozzle process. Remote agents advertise their own names — set DOZZLE_HOSTNAME (or --hostname) on each agent to control how it appears in the multi-host menu. In swarm mode each node runs its own agent, so give each node a distinct hostname to tell them apart.
