Introduction This is a golang library for working with container
registries. It's largely based on the Python library of the same name
(https://github.com/google/containerregistry).
.
The following diagram shows the main types that this library handles.
OCI image representation Tools This repo hosts some tools built on top
of the library. crane crane (cmd/crane/doc/crane.md) is a tool for
interacting with remote images and registries. Installation
.
GO111MODULE=on go get -u github.com/google/go-containerregistry/cmd/crane
.
Images You can also use crane as docker image
.
```sh $ docker run --rm gcr.io/go-containerregistry/crane ls ubuntu
.
2019/12/03 09:33:01 No matching credentials were found, falling back on
anonymous 10.04 12.04.5 12.04 12.10 ```
.
And it's also available with a shell, which uses the debug tag
.
sh docker run --rm -it --entrypoint "/busybox/sh"
gcr.io/go-containerregistry/crane:debug
.
gcrane gcrane (cmd/gcrane/README.md) is a GCR-specific variant of crane
that has richer output for the ls subcommand and some basic garbage
collection support. Installation
.
GO111MODULE=on go get -u github.com/google/go-containerregistry/cmd/gcrane
.
Images You can also use gcrane as docker image
.
```sh $ docker run --rm gcr.io/go-containerregistry/gcrane ls ubuntu
.
2019/12/03 09:33:01 No matching credentials were found, falling back on
anonymous 10.04 12.04.5 12.04 12.10 ```
.
And it's also available with a shell, which uses the debug tag
.
sh docker run --rm -it --entrypoint "/busybox/sh"
gcr.io/go-containerregistry/gcrane:debug
.
k8schain k8schain (pkg/authn/k8schain/README.md) implements the
authentication semantics use by kubelets in a way that is easily
consumable by this library.
.
k8schain is not a standalone tool, but it's linked here
for visibility. Debug images for crane and gcrane crane and
gcrane also provide a debug image (containing a shell), which
can be found at • gcr.io/go-containerregistry/crane:debug•
gcr.io/go-containerregistry/gcrane:debug Inside these images, crane and
gcrane can be used like this:
.
sh /ko-app/crane cp ...
.
Emeritus: ko (https://github.com/google/ko) This tool was originally
developed in this repo but has since been moved to its own repo.
Reasoning:
go-containerregistry is a dependency for container-diff (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=945524)
