Problem

The client need simple app to check the log in realtime to debug their app (that have been containerized).

What I Used in This Tutorial

1. Docker version 24.0.6, build ed223bc

2. Ubuntu 22.04.3 LTS

3. Dozzle v5.0.5

How To

1. Create docker-compose.yml

version: "3,8"
services:
  dozzle:
    container_name: dozzle
    image: amir20/dozzle:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 9999:8080
    environment:
      DOZZLE_NO_ANALYTICS: true

Run it using docker-compose up -d

2. You can check at http://lcoalhost:9999

Notes:

1. If you want to serve Dozzle with sub path, use

version: "3,8"
services:
  dozzle:
    container_name: dozzle
    image: amir20/dozzle:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 9999:8080
    environment:
      DOZZLE_NO_ANALYTICS: true
      DOZZLE_BASE: dozzle

Conclusion

1. It work on docker swarm mode but it doesn’t work on cluster

2. It has built-in basic auth option, but i prefer using basic auth on nginx. Because it was easier to setup fail2ban nginx-http-auth with it/

3. It fit for people who want to look their realtime log, not for you who want to keep their log forever (you can use Seq for this purpose)

Dozzle is a handy tool for monitoring your Docker container logs in real-time. With its simple setup and web interface, it provides an easy way to keep an eye on your containers and quickly identify any issues. Whether you’re running a single container or managing a fleet of them, Dozzle can be a valuable addition to your container management toolkit.
