The end goal is to provide a -set of versatile primitives that can compose to do extraordinarily powerful things efficiently and easily. - -Both the resource views and mutations may be lazy, eager, memoizing, etc, and most are optimized -for common paths based on the tooling we have seen in the wild (e.g. writing new images from disk -to the registry as a compressed tarball). - - -### Experiments - -Over time, we will add new functionality under experimental environment variables listed here. - -| Env Var | Value(s) | What is does | -|---------|----------|--------------| -| `GGCR_EXPERIMENT_ESTARGZ` | `"1"` | ⚠️DEPRECATED⚠️: When enabled this experiment will direct `tarball.LayerFromOpener` to emit [estargz](https://github.com/opencontainers/image-spec/issues/815) compatible layers, which enable them to be lazily loaded by an appropriately configured containerd. | - - -### `v1.Image` - -#### Sources - -* [`remote.Image`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#Image) -* [`tarball.Image`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/tarball#Image) -* [`daemon.Image`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/daemon#Image) -* [`layout.Image`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/layout#Path.Image) -* [`random.Image`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/random#Image) - -#### Sinks - -* [`remote.Write`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#Write) -* [`tarball.Write`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/tarball#Write) -* [`daemon.Write`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/daemon#Write) -* [`legacy/tarball.Write`](https://godoc.org/github.com/google/go-containerregistry/pkg/legacy/tarball#Write) -* [`layout.AppendImage`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/layout#Path.AppendImage) - -### `v1.ImageIndex` - -#### Sources - -* [`remote.Index`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#Index) -* [`random.Index`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/random#Index) -* [`layout.ImageIndexFromPath`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/layout#ImageIndexFromPath) - -#### Sinks - -* [`remote.WriteIndex`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#WriteIndex) -* [`layout.Write`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/layout#Write) - -### `v1.Layer` - -#### Sources - -* [`remote.Layer`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#Layer) -* [`tarball.LayerFromFile`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/tarball#LayerFromFile) -* [`random.Layer`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/random#Layer) -* [`stream.Layer`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/stream#Layer) - -#### Sinks - -* [`remote.WriteLayer`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#WriteLayer) - -## Overview - -### `mutate` - -The simplest use for these libraries is to read from one source and write to another. - -For example, - - * `crane pull` is `remote.Image -> tarball.Write`, - * `crane push` is `tarball.Image -> remote.Write`, - * `crane cp` is `remote.Image -> remote.Write`. - -However, often you actually want to _change something_ about an image. -This is the purpose of the [`mutate`](pkg/v1/mutate) package, which exposes -some commonly useful things to change about an image. - -### `partial` - -If you're trying to use this library with a different source or sink than it already supports, -it can be somewhat cumbersome. The `Image` and `Layer` interfaces are pretty wide, with a lot -of redundant information. This is somewhat by design, because we want to expose this information -as efficiently as possible where we can, but again it is a pain to implement yourself. - -The purpose of the [`partial`](pkg/v1/partial) package is to make implementing a `v1.Image` -much easier, by filling in all the derived accessors for you if you implement a minimal -subset of `v1.Image`. - -### `transport` - -You might think our abstractions are bad and you just want to authenticate -and send requests to a registry. - -This is the purpose of the [`transport`](pkg/v1/remote/transport) and [`authn`](pkg/authn) packages. - -## Tools - -This repo hosts some tools built on top of the library. - -### `crane` - -[`crane`](cmd/crane/README.md) is a tool for interacting with remote images -and registries. - -### `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. - -### `krane` - -[`krane`](cmd/krane/README.md) is a drop-in replacement for `crane` that supports -common Kubernetes-based workload identity mechanisms using [`k8schain`](#k8schain) -as a fallback to traditional authentication mechanisms. - -### `k8schain` - -[`k8schain`](pkg/authn/k8schain/README.md) implements the authentication -semantics used by kubelets in a way that is easily consumable by this library. - -`k8schain` is not a standalone tool, but it is linked here for visibility. - -### Emeritus: [`ko`](https://github.com/google/ko) - -This tool was originally developed in this repo but has since been moved to its -own repo. diff --git a/pkg/go-containerregistry/SECURITY.md b/pkg/go-containerregistry/SECURITY.md deleted file mode 100644 index ce1f393f6..000000000 --- a/pkg/go-containerregistry/SECURITY.md +++ /dev/null @@ -1,4 +0,0 @@ -To report a security issue, please use http://g.co/vulnz.

sure to remove the leading `/` from the path (not `/etc/passwd`). This behavior will not follow symlinks. - -### Bundle directory contents into an image - -``` -crane append -f <(tar -f - -c some-dir/) -t ${IMAGE} -``` - -By default, this produces an image with one layer containing the directory contents. Add `-b ${BASE_IMAGE}` to append the layer to a base image instead. - -You can extend this even further with `crane mutate`, to make an executable in the appended layer the image's entrypoint. - -``` -crane mutate ${IMAGE} --entrypoint=some-dir/entrypoint.sh -``` - -Because `crane append` emits the full image reference, these calls can even be chained together: - -``` -crane mutate $( - crane append -f <(tar -f - -c some-dir/) -t ${IMAGE} -) --entrypoint=some-dir/entrypoint.sh -``` - -This will bundle `some-dir/` into an image, push it, mutate its entrypoint to `some-dir/entrypoint.sh`, and push that new image by digest. - -### Diff two configs - -``` -diff <(crane config busybox:1.32 | jq) <(crane config busybox:1.33 | jq) -``` - -### Diff two manifests - -``` -diff <(crane manifest

<(crane export gcr.io/kaniko-project/executor:v1.7.0-debug - | tar -tvf - | sort) -``` - -This will show file size diffs and (unfortunately) modified time diffs. - -With some work, you can use `cut` and other built-in Unix tools to ignore these diffs. - -### Get total image size - -Given an image manifest, you can calculate the total size of all layer blobs and the image's config blob using `jq`: - -``` -crane manifest gcr.io/buildpacks/builder:v1 | jq '.config.size + ([.layers[].size] | add)' -``` - -This will produce a number of bytes, which you can make human-readable by passing to [`numfmt`](https://www.gnu.org/software/coreutils/manual/html_node/numfmt-invocation.html) - -``` -crane manifest gcr.io/buildpacks/builder:v1 | jq '.config.size + ([.layers[].size] | add)' | numfmt --to=iec -``` - -For image indexes, you can pass the `--platform` flag to `crane` to get a platform-specific image. - -### Filter irrelevant platforms from a multi-platform image - -Perhaps you use a base image that supports a wide variety of exotic platforms, but you only care about linux/amd64 and linux/arm64. -If you want to copy that base image into a different registry, you will end up with a bunch of images you don't use. -You can filter the base to include only platforms that are relevant to you. - -``` -crane index filter ubuntu --platform linux/amd64 --platform linux/arm64 -t ${IMAGE} -``` - -Note that this will obviously modify the digest of the multi-platform image you're using, so this may invalidate other artifacts that reference it, e.g. signatures. - -### Create a multi-platform image from scratch - -If you have a bunch of platform-specific images that you want to turn into a multi-platform image, `crane index append` can do that: - -``` -crane index append -t ${IMAGE} \ - -m ubuntu@sha256:c985bc3f77946b8e92c9a3648c6f31751a7dd972e06604785e47303f4ad47c4c \ - -m ubuntu@sha256:61bd0b97000996232eb07b8d0e9375d14197f78aa850c2506417ef995a7199a7 -``` - -Note that this is less flexible than [`manifest-tool`](https://github.com/estesp/manifest-tool) because it derives the platform from each image's config file, but it should work in most cases. diff --git

- -## Mutations - -This is obviously not a comprehensive set of useful transformations (PRs welcome!), -but a rough summary of what the `mutate` package currently does: - -### `Config` and `ConfigFile` - -These allow you to change the [image configuration](https://github.com/opencontainers/image-spec/blob/master/config.md#properties), -e.g. to change the entrypoint, environment, author, etc. - -### `Time`, `Canonical`, and `CreatedAt` - -These are useful in the context of [reproducible builds](https://reproducible-builds.org/), -where you may want to strip timestamps and other non-reproducible information. - -### `Append`, `AppendLayers`, and `AppendManifests` - -These functions allow the extension of a `v1.Image` or `v1.ImageIndex` with -new layers or manifests. - -For constructing an image `FROM scratch`, see the [`empty`](/pkg/v1/empty) package. - -### `MediaType` and `IndexMediaType` - -Sometimes, it is necessary to change the media type of an image or index, -e.g. to appease a registry with strict validation of images (_looking at you, GCR_). - -### `Rebase` - -Rebase has [its own README](/cmd/crane/rebase.md). - -This is the underlying implementation of [`crane rebase`](https://github.com/google/go-containerregistry/blob/main/cmd/crane/doc/crane_rebase.md). - -### `Extract` - -Extract will flatten an image filesystem into a single tar stream, -respecting whiteout files. - -This is the underlying implementation of [`crane export`](https://github.com/google/go-containerregistry/blob/main/cmd/crane/doc/crane_export.md). diff --git a/pkg/go-containerregistry/pkg/v1/mutate/doc.go b/pkg/go-containerregistry/pkg/v1/mutate/doc.go deleted file mode 100644 index dfbd9951e..000000000 --- a/pkg/go-containerregistry/pkg/v1/mutate/doc.go +++ /dev/null @@ -1,16 +0,0 @@ -// Copyright 2018 Google LLC All Rights Reserved. -// -// Licensed under the Apache License, Version 2.0 (the "License");

- - -## Background - -There are a lot of confusingly similar terms that come up when talking about images in registries. - -### Anatomy of an image - -In general... - -* A tag refers to an image manifest. -* An image manifest references a config file and an orderered list of _compressed_ layers by sha256 digest. -* A config file references an ordered list of _uncompressed_ layers by sha256 digest and contains runtime configuration. -* The sha256 digest of the config file is the [image id](https://github.com/opencontainers/image-spec/blob/master/config.md#imageid) for the image. - -For example, an image with two layers would look something like this: - -![image anatomy](/images/image-anatomy.dot.svg) - -### Anatomy of an index - -In the normal case, an [index](https://github.com/opencontainers/image-spec/blob/master/image-index.md) is used to represent a multi-platform image. -This was the original use case for a [manifest -list](https://docs.docker.com/registry/spec/manifest-v2-2/#manifest-list). - -![image index anatomy](/images/index-anatomy.dot.svg) - -It is possible for an index to reference another index, per the OCI -[image-spec](https://github.com/opencontainers/image-spec/blob/master/media-types.md#compatibility-matrix). -In theory, both an image and image index can reference arbitrary things via -[descriptors](https://github.com/opencontainers/image-spec/blob/master/descriptor.md), -e.g. see the [image layout -example](https://github.com/opencontainers/image-spec/blob/master/image-layout.md#index-example), -which references an application/xml file from an image index. - -That could look something like this: - -![strange image index anatomy](/images/index-anatomy-strange.dot.svg) - -Using a recursive index like this might not be possible with all registries, -but this flexibility allows for some interesting applications, e.g. the -[OCI Artifacts](https://github.com/opencontainers/artifacts) effort. - -### Anatomy of an image upload - -The structure of an image requires a delicate ordering when uploading an image to a registry. -Below is a (slightly simplified) figure that describes how an image is prepared for upload -to a registry and how the data flows between various artifacts: - -![upload](/images/upload.dot.svg) - -Note that: - -* A config file references the uncompressed layer contents by sha256. -* A manifest references the compressed layer contents by sha256 and the size of the layer. -* A manifest references the config file contents by sha256 and the size of the file. - -It follows that during an upload, we need to upload layers before the config file, -and we need to upload the config file before the manifest. - -Sometimes, we know all of this information ahead of time, (e.g. when copying from remote.Image), -so the ordering is less important. - -In other cases, e.g. when using a [`stream.Layer`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/stream#Layer), -we can't compute anything until we have already uploaded the layer, so we need to be careful about ordering. - -## Caveats - -### schema 1 - -This package does not support schema 1 images, see [`#377`](https://github.com/google/go-containerregistry/issues/377), -however, it's possible to do _something_ useful with them via [`remote.Get`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote#Get), -which doesn't try to interpret what is returned by the registry. - -[`crane.Copy`](https://godoc.org/github.com/google/go-containerregistry/pkg/crane#Copy) takes advantage of this to implement support for copying schema 1 images, -see [here](https://github.com/google/go-containerregistry/blob/main/pkg/internal/legacy/copy.go). diff --git a/pkg/go-containerregistry/pkg/v1/remote/catalog.go b/pkg/go-containerregistry/pkg/v1/remote/catalog.go deleted file mode 100644 index a87f81a2a..000000000 --- a/pkg/go-containerregistry/pkg/v1/remote/catalog.go +++ /dev/null @@ -1,159 +0,0 @@ -// Copyright 2019 Google LLC All Rights Reserved. -// -// Licensed under the Apache License, Version 2.0 (the "License");

b7631f5005670623a623cad0d83f149f8f8d83c4 Mon Sep 17 00:00:00 2001 From: Ignasi Date: Thu, 8 Jan 2026 19:31:20 +0100 Subject: [PATCH 2/3] fix for removing ggcr (#545) * Add Docker Hub integration tests and hostname remapping for API requests * Refactor Docker Model Runner setup to use a configuration struct for environment variables and log messages * Update go.mod dependencies to include latest versions of cloud.google.com/go/compute/metadata and golang.org/x/oauth2 * Add support for HuggingFace registry in manifest fetching * Refactor manifest endpoint logic to apply it only on HF repos * Remove Docker Hub hostname remapping and update manifest fetching logic for HuggingFace registry --- cmd/cli/commands/integration_test.go | 120 ++++++++++++++++++++++++-- go.work.sum | 2 +

-[![GoDoc](https://godoc.org/github.com/google/go-containerregistry/pkg/authn?status.svg)](https://godoc.org/github.com/google/go-containerregistry/pkg/authn) - -This README outlines how we acquire and use credentials when interacting with a registry. - -As much as possible, we attempt to emulate `docker`'s authentication behavior and configuration so that this library "just works" if you've already configured credentials that work with `docker`; however, when things don't work, a basic understanding of what's going on can help with debugging. - -The official documentation for how authentication with `docker` works is (reasonably) scattered across several different sites and GitHub repositories, so we've tried to summarize the relevant bits here. - -## tl;dr for consumers of this package - -By default, [`pkg/v1/remote`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/remote) uses [`Anonymous`](https://godoc.org/github.com/google/go-containerregistry/pkg/authn#Anonymous) credentials (i.e. _none_), which for most registries will only allow read access to public images. - -To use the credentials found in your Docker config file, you can use the [`DefaultKeychain`](https://godoc.org/github.com/google/go-containerregistry/pkg/authn#DefaultKeychain), e.g.: - -```go -package main - -import ( - "fmt" - - "github.com/google/go-containerregistry/pkg/authn" - "github.com/google/go-containerregistry/pkg/name" - "github.com/google/go-containerregistry/pkg/v1/remote" -) - -func main() { -

if err != nil { - panic(err) - } - - // Prints the digest of registry.example.com/private/repo - fmt.Println(img.Digest) -} -``` - -The `DefaultKeychain` will use credentials as described in your Docker config file -- usually `~/.docker/config.json`, or `%USERPROFILE%\.docker\config.json` on Windows -- or the location described by the `DOCKER_CONFIG` environment variable, if set. - -If those are not found, `DefaultKeychain` will look for credentials configured using [Podman's expectation](https://docs.podman.io/en/latest/markdown/podman-login.1.html) that these are found in `${XDG_RUNTIME_DIR}/containers/auth.json`. - -[See below](#docker-config-auth) for more information about what is configured in this file. - -## Emulating Cloud Provider Credential Helpers - -[`pkg/v1/google.Keychain`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/v1/google#Keychain) provides a `Keychain` implementation that emulates [`docker-credential-gcr`](https://github.com/GoogleCloudPlatform/docker-credential-gcr) to find credentials in the environment. -See [`google.NewEnvAuthenticator`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/v1/google#NewEnvAuthenticator) and [`google.NewGcloudAuthenticator`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/v1/google#NewGcloudAuthenticator) for more information. - -To emulate other credential helpers without requiring them to be available as executables, [`NewKeychainFromHelper`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/authn#NewKeychainFromHelper) provides an adapter that takes a Go implementation satisfying a subset of the [`credentials.Helper`](https://pkg.go.dev/github.com/docker/docker-credential-helpers/credentials#Helper) interface, and makes it available as a `Keychain`. - -This means that you can emulate, for example, [Amazon ECR's `docker-credential-ecr-login` credential helper](https://github.com/awslabs/amazon-ecr-credential-helper) using the same implementation: - -```go -import ( - ecr "github.com/awslabs/amazon-ecr-credential-helper/ecr-login" - "github.com/awslabs/amazon-ecr-credential-helper/ecr-login/api" - - "github.com/google/go-containerregistry/pkg/authn" - "github.com/google/go-containerregistry/pkg/v1/remote" -) - -func main() { - // ... - ecrHelper := ecr.ECRHelper{ClientFactory: api.DefaultClientFactory{}} - img, err := remote.Get(ref, remote.WithAuthFromKeychain(authn.NewKeychainFromHelper(ecrHelper))) - if err != nil { - panic(err) - } - // ... -} -``` - -Likewise, you can emulate [Azure's ACR `docker-credential-acr-env` credential helper](https://github.com/chrismellard/docker-credential-acr-env): - -```go -import ( - "github.com/chrismellard/docker-credential-acr-env/pkg/credhelper" - - "github.com/google/go-containerregistry/pkg/authn" - "github.com/google/go-containerregistry/pkg/v1/remote" -) - -func main() { - // ... - acrHelper := credhelper.NewACRCredentialsHelper() - img, err := remote.Get(ref, remote.WithAuthFromKeychain(authn.NewKeychainFromHelper(acrHelper))) - if err != nil { - panic(err) - } - // ... -} -``` - - - -## Using Multiple `Keychain`s - -[`NewMultiKeychain`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/authn#NewMultiKeychain) allows you to specify multiple `Keychain` implementations, which will be checked in order when credentials are needed. - -For example: - -```go -kc := authn.NewMultiKeychain( - authn.DefaultKeychain, - google.Keychain, - authn.NewKeychainFromHelper(ecr.ECRHelper{ClientFactory: api.DefaultClientFactory{}}), - authn.NewKeychainFromHelper(acr.ACRCredHelper{}), -) -``` - -This multi-keychain will: - -- first check for credentials found in the Docker config file, as describe above, then -- check for GCP credentials available in the environment, as described above, then -- check for ECR credentials by emulating the ECR credential helper, then -- check for ACR credentials by emulating the ACR credential helper. - -If any keychain implementation is able to provide credentials for the request, they will be used, and further keychain implementations will not be consulted. - -If no implementations are able to provide credentials, `Anonymous` credentials will be used. - -## Docker Config Auth - -What follows attempts to gather useful information about Docker's config.json and make it available in one place. - -If you have questions, please [file an issue](https://github.com/google/go-containerregistry/issues/new). - -### Plaintext - -The config file is where your credentials are stored when you invoke `docker login`, e.g. the contents may look something like this: - -```json -{ - "auths": { - "registry.example.com": { - "auth": "QXp1cmVEaWFtb25kOmh1bnRlcjI=" - } - } -} -``` - -The `auths` map has an entry per registry, and the `auth` field contains your username and password encoded as [HTTP 'Basic' Auth](https://tools.ietf.org/html/rfc7617). - -**NOTE**: This means that your credentials are stored _in plaintext_: - -```bash -$ echo "QXp1cmVEaWFtb25kOmh1bnRlcjI=" | base64 -d -AzureDiamond:hunter2 -``` - -For what it's worth, this config file is equivalent to: - -```json -{ - "auths": { - "registry.example.com": { - "username": "AzureDiamond", - "password": "hunter2" - } - } -} -``` - -... which is useful to know if e.g. your CI system provides you a registry username and password via environment variables and you want to populate this file manually without invoking `docker login`. - -### Helpers - -If you log in like this, `docker` will warn you that you should use a [credential helper](https://docs.docker.com/engine/reference/commandline/login/#credentials-store), and you should! - -To configure a global credential helper: -```json -{ - "credsStore": "osxkeychain" -} -``` - -To configure a per-registry credential helper: -```json -{ - "credHelpers": { - "gcr.io": "gcr" - } -} -``` - -We use [`github.com/docker/cli/cli/config.Load`](https://godoc.org/github.com/docker/cli/cli/config#Load) to parse the config file and invoke any necessary credential helpers. This handles the logic of taking a [`ConfigFile`](https://github.com/docker/cli/blob/ba63a92655c0bea4857b8d6cc4991498858b3c60/cli/config/configfile/file.go#L25-L54) + registry domain and producing an [`AuthConfig`](https://github.com/docker/cli/blob/ba63a92655c0bea4857b8d6cc4991498858b3c60/cli/config/types/authconfig.go#L3-L22), which determines how we authenticate to the registry. - -## Credential Helpers - -The [credential helper protocol](https://github.com/docker/docker-credential-helpers) allows you to configure a binary that supplies credentials for the registry, rather than hard-coding them in the config file. - -The protocol has several verbs, but the one we most care about is `get`. - -For example, using the following config file: -```json -{ - "credHelpers": { - "gcr.io": "gcr", - "eu.gcr.io": "gcr" - } -} -``` - -To acquire credentials for `gcr.io`, we look in the `credHelpers` map to find -the credential helper for `gcr.io` is `gcr`. By appending that value to -`docker-credential-`, we can get the name of the binary we need to use. - -For this example, that's `docker-credential-gcr`, which must be on our `$PATH`. -We'll then invoke that binary to get credentials: - -```bash -$ echo "gcr.io" | docker-credential-gcr get -{"Username":"_token","Secret":""} -``` - -You can configure the same credential helper for multiple registries, which is -why we need to pass the domain in via STDIN, e.g. if we were trying to access -`eu.gcr.io`, we'd do this instead: - -```bash -$ echo "eu.gcr.io" | docker-credential-gcr get -{"Username":"_token","Secret":""} -``` - -### Debugging credential helpers - -If a credential helper is configured but doesn't seem to be working, it can be -challenging to debug. Implementing a fake credential helper lets you poke around -to make it easier to see where the failure is happening. - -This "implements" a credential helper with hard-coded values: -``` -#!/usr/bin/env bash -echo '{"Username":"","Secret":"hunter2"}' -``` - - -This implements a credential helper that prints the output of -`docker-credential-gcr` to both stderr and whatever called it, which allows you -to snoop on another credential helper: -``` -#!/usr/bin/env bash -docker-credential-gcr $@ | tee >(cat 1>&2) -``` - -Put those files somewhere on your path, naming them e.g. -`docker-credential-hardcoded` and `docker-credential-tee`, then modify the -config file to use them: - -```json -{ - "credHelpers": { - "gcr.io": "tee", - "eu.gcr.io": "hardcoded" - } -} -``` - -The `docker-credential-tee` trick works with both `crane` and `docker`: - -```bash -$ crane manifest gcr.io/google-containers/pause > /dev/null -{"ServerURL":"","Username":"_dcgcr_1_5_0_token","Secret":""} - -$ docker pull gcr.io/google-containers/pause -Using default tag: latest -{"ServerURL":"","Username":"_dcgcr_1_5_0_token","Secret":""} -latest: Pulling from google-containers/pause -a3ed95caeb02: Pull complete -4964c72cd024: Pull complete -Digest: sha256:a78c2d6208eff9b672de43f880093100050983047b7b0afe0217d3656e1b0d5f -Status: Downloaded newer image for gcr.io/google-containers/pause:latest -gcr.io/google-containers/pause:latest -``` - -## The Registry - -There are two methods for authenticating against a registry: -[token](https://docs.docker.com/registry/spec/auth/token/) and -[oauth2](https://docs.docker.com/registry/spec/auth/oauth/). - -Both methods are used to acquire an opaque `Bearer` token (or -[RegistryToken](https://github.com/docker/cli/blob/ba63a92655c0bea4857b8d6cc4991498858b3c60/cli/config/types/authconfig.go#L21)) -to use in the `Authorization` header.
