About dozzle
Dozzle is a lightweight, web based application for monitoring Docker logs in real time. It is written in Go and distributed under the MIT license, and it lives in the container and orchestration ecosystem alongside Docker, Docker Swarm and Kubernetes, which its topics and tagline both name. The project ships as a small container — roughly 7 MB compressed — and its user interface is built with Vue.js. It exposes a browser view over logs rather than writing them anywhere: the README states plainly that Dozzle stores no log files and exists purely for live log viewing.
