A library for working with container image contents, layer file trees, and squashed file trees.
See examples/basic.go
docker image save centos:8 -o centos.tar
go run examples/basic.go ./centos.tar
Note: To run tests you will need skopeo
installed.
This library provides the means to:
- parse and read images from multiple sources, supporting:
- docker V2 schema images from the docker daemon, podman, or archive
- OCI images from disk, directory, or registry
- singularity formatted image files
- build a file tree representing each layer blob
- create a squashed file tree representation for each layer
- search one or more file trees for selected paths
- catalog file metadata in all layers
- query the underlying image tar for content (file content within a layer)
