Doku is a simple, lightweight web-based application that allows you to monitor Docker disk usage in a user-friendly manner. The Doku displays the amount of disk space used by the Docker daemon, splits by images, containers, volumes, and builder cache. If you're lucky, you'll also see the sizes of log files :)
Doku should work for most. It has been tested with dozen of hosts.

Doku is a very small Docker container (6 MB compressed). Pull the latest release from the index:
docker pull amerkurev/doku:latest
The simplest way to use Doku is to run the Docker container. Mount the Docker Unix socket with -v to /var/run/docker.sock. Also, you need to mount the top-level directory (/) on the host machine in ro mode. Otherwise, Doku will not be able to calculate the size of the logs and bind mounts.
docker run --name doku -d -v /var/run/docker.sock:/var/run/docker.sock:ro -v /:/hostroot:ro -p 9090:9090 amerkurev/doku
Use following configuration for docker compose:
version: "3"
services:
docu:
image: amerkurev/doku:v0.0.16
ports:
- 9090:9090
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
- /:/hostroot:roDoku will be available at http://localhost:9090/. You can change -p 9090:9090 to any port. For example, if you want to view Doku over port 8080 then you would do -p 8080:9090.
Doku supports basic auth for all requests. This functionality is disabled by default.
In order to enable basic auth, user should set the typical htpasswd file with --basic-htpasswd=<file location> or env BASIC_HTPASSWD=<file location>.
Doku expects htpasswd file to be crypted with bcrypt algorithm in the following format:
username1:bcrypt(password1)
username2:bcrypt(password2)
...
this can be generated with htpasswd -nbB command, i.e. htpasswd -nbB test passwd
