diving-rs

Exploring each layer in a docker image, it's fast and simple, developed with Rust. There are two modes: terminal(default) and web.

It does not depend on anything, including docker client.

It supports multiple platforms: linux, windows and macos, you can get it from release page.

Note: Since the layer data needs to be downloaded from the source, such as Docker Hub, it may take a long time, if times out, please try again, it is recommended that the download program be executed locally. For image sources deployed privately, you can deploy the image of Diving on a machine that can access the image source.

config

The config file is ~/.diving/config.yml, the options:

layer_path: The path of layer cache, default is ~/.diving/layers
layer_ttl: The ttl of layer, default is 90d. The layer will be purged if it is not accessed again for 90 days

terminal

Supports three data source modes analyze image. The specific form is as follows:

registry get image form docker registry or other registry
docker get image from local docker client
file get image for tar file

It should be noted that it does not run as root, so the mounted directory needs to add the permission(r+w), otherwise it will fail to start.
