Dozzle Setup

Dozzle is a small and lightweight application with a web-based interface to monitor docker logs. It doesn't store any log files. It is for live monitoring of your container logs.

Initial Setup

Dozzle's installation is very simple, i will install it on my current debian VM that i use to run my docker containers:

root@docker0:~# docker container ls -a --format "table {{.ID}} \t {{.Names}} \t {{.Size}}"
CONTAINER ID         NAMES                  SIZE
e037d2364879         asciinema_nginx        2B (virtual 16.1MB)
b513c2c6894e         asciinema_phoenix      3.89MB (virtual 97.2MB)

f33ae4911086         searx2                 25.1kB (virtual 164MB)
0ab72043d028         searx                  0B (virtual 164MB)
	

So in order to monitor them, we can use dozzle, let's install it:

root@docker0:~# docker pull amir20/dozzle:latest

And from here, we have access to our Dozzle instance from port 8888:

Usage

One of dozzle's great features is the regex / Find feature, to use it just type CTRL+F and type in the pattern you want to match in the logs:

you can also change the default settings:
