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.

-[![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() { - ref, err := name.ParseReference("registry.example.com/private/repo") - if err != nil { - panic(err) - } - - // Fetch the manifest using default credentials. - img, err := remote.Get(ref, remote.WithAuthFromKeychain(authn.DefaultKeychain)) - 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.

[`authn.Keychain`](https://godoc.org/github.com/google/go-containerregistry/authn#Keychain) interface loosely based on the authentication semantics used by the Kubelet when performing the pull of a Pod's images. - -This keychain supports passing a Kubernetes Service Account and some ImagePullSecrets which may represent registry credentials. - -In addition to those, the keychain also includes cloud-specific credential helpers for Google Container Registry (and Artifact Registry), Azure Container Registry, and Amazon AWS Elasic Container Registry. -This means that if the keychain is used from within Kubernetes services on those clouds (GKE, AKS, EKS), any available service credentials will be discovered and used. - -In general this keychain should be used when the code is expected to run in a Kubernetes cluster, and especially when it will run in one of those clouds. -To get a cloud-agnostic keychain, use [`pkg/authn/kubernetes`](../kubernetes) instead. - -To get only cloud-aware keychains, use [`google.Keychain`](https://godoc.org/github.com/google/go-containerregistry/pkg/v1/google#Keychain), or [`pkg/authn.NewKeychainFromHelper`](https://godoc.org/github.com/google/go-containerregistry/pkg/authn#NewKeychainFromHelper) with a cloud credential helper implementation -- see the implementation of `k8schain.NewNoClient` for more details. - -## Usage - -### Creating a keychain - -A `k8schain` keychain can be built via one of: - -```go -// client is a kubernetes.Interface -kc, err := k8schain.New(ctx, client, k8schain.Options{}) -... - -// This method is suitable for use by controllers or other in-cluster processes. -kc, err := k8schain.NewInCluster(ctx, k8schain.Options{}) -... -``` - -### Using the keychain - -The `k8schain` keychain can be used directly as an `authn.Keychain`, e.g. - -```go -auth, err := kc.Resolve(registry) -if err != nil { - ... -} -``` - -Or, with the [`remote.WithAuthFromKeychain`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/v1/remote#WithAuthFromKeychain) option: - -```go -img, err := remote.Image(ref, remote.WithAuthFromKeychain(kc)) -if err != nil { - ... -} -``` diff --git a/pkg/go-containerregistry/pkg/authn/k8schain/doc.go b/pkg/go-containerregistry/pkg/authn/k8schain/doc.go deleted file mode
