of supported transports for copying and storing container images + +## DESCRIPTION + +Tools which use the containers/image library, including skopeo(1), buildah(1), podman(1), all share a common syntax for referring to container images in various locations. +The general form of the syntax is _transport:details_, where details are dependent on the specified transport, which are documented below. + +### **containers-storage:** [storage-specifier]{image-id|docker-reference[@image-id]} + +An image located in a local containers storage. +The format of _docker-reference_ is described in detail in the **docker** transport. + +The _storage-specifier_ allows for referencing storage locations on the file system and has the format `[[driver@]root[+run-root][:options]]` where the optional `driver` refers to the storage driver (e.g., overlay or btrfs) and where `root` is an absolute path to the storage's root directory. +The optional `run-root` can be used to specify the run directory of the storage where all temporary writable content is stored. +The optional `options` are a comma-separated list of driver-specific options. +Please refer to containers-storage.conf(5) for further information on the drivers and supported options. + +### **dir:**_path_ + +An existing local directory _path_ storing the manifest, layer tarballs and signatures as individual files. +This is a non-standardized format, primarily useful for debugging or noninvasive container inspection. + +### **docker://**_docker-reference_ + +An image in a registry implementing the "Docker Registry HTTP API V2". +By default, uses the authorization state in `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using podman-login(1). +If the authorization state is not found there, `$HOME/.docker/config.json` is checked, which is set using docker-login(1). +The containers-registries.conf(5) further allows for configuring various settings of a registry. + +Note that a _docker-reference_ has the following format: `name[:tag|@digest]`. +While the docker transport does not support both a tag and a digest at the same time some formats like containers-storage do. +Digests can also be used in an image destination as long as the manifest matches the provided digest. +The digest of images can be explored with skopeo-inspect(1). +If `name` does not contain a slash, it is treated as `docker.io/library/name`. +Otherwise, the component before the first slash is checked if it is recognized as a `hostname[:port]` (i.e., it contains either a . or a :, or the component is exactly localhost). +If the first component of name is not recognized as a `hostname[:port]`, `name` is treated as `docker.io/name`. + +### **docker-archive:**_path[:docker-reference]_ + +An image is stored in the docker-save(1) formatted file. +_docker-reference_ is only used when creating such a file, and it must not contain a digest. +It is further possible to copy data to stdin by specifying `docker-archive:/dev/stdin` but note that the used file must be seekable. + +### **docker-daemon:**_docker-reference|algo:digest_ + +An image stored in the docker daemon's internal storage. +The image must be specified as a _docker-reference_ or in an alternative _algo:digest_ format when being used as an image source. +The _algo:digest_ refers to the image ID reported by docker-inspect(1). + +### **oci:**_path[:tag]_ + +An image compliant with the "Open Container Image Layout Specification" at _path_. +Using a _tag_ is optional and allows for storing multiple images at the same _path_. + +### **oci-archive:**_path[:tag]_ + +An image compliant with the "Open Container Image Layout Specification" stored as a tar(1) archive at _path_. + +###

The policy requirements -are represented as a JSON array of individual requirement objects. For an image to be accepted, -*all* of the requirements must be satisfied simulatenously. - -The policy requirements can also be used to decide whether an individual signature is accepted (= is signed by a recognized key of a known author); -in that case some requirements may apply only to some signatures, but each signature must be accepted by *at least one* requirement object. - -The following requirement objects are supported: - -### `insecureAcceptAnything` - -A simple requirement with the following syntax - -```json -{"type":"insecureAcceptAnything"} -``` - -This requirement accepts any image (but note that other requirements in the array still apply). - -When deciding to accept an individual signature, this requirement does not have any effect; it does *not* cause the signature to be accepted, though. - -This is useful primarily for policy scopes where no signature verification is required; -because the array of policy requirements must not be empty, this requirement is used -to represent the lack of requirements explicitly. - -### `reject` - -A simple requirement with the following syntax: - -```json -{"type":"reject"} -``` - -This requirement rejects every image, and every signature. - -### `signedBy` - -This requirement requires an image to be signed with an expected identity, or accepts a signature if it is using an expected identity and key. - -```js -{ - "type": "signedBy", - "keyType": "GPGKeys", /* The only currently supported value */ - "keyPath": "/path/to/local/keyring/file", - "keyData": "base64-encoded-keyring-data", - "signedIdentity": identity_requirement -} -``` - - -Exactly one of `keyPath` and `keyData` must be present, containing a GPG keyring of one or more public keys. Only signatures made by these keys are accepted. - -The `signedIdentity` field, a JSON object, specifies what image identity the signature claims about the image. -One of the following alternatives are supported: - -- The identity in the signature must exactly match the image identity. Note that with this, referencing an image by digest (with a signature claiming a _repository_`:`_tag_ identity) will fail. - - ```json - {"type":"matchExact"} - ``` -- If the image identity carries a tag, the identity in the signature must exactly match; - if the image identity uses a digest reference, the identity in the signature must be in the same repository as the image identity (using any tag). - - (Note that with images identified using digest references, the digest from the reference is validated even before signature verification starts.) - - ```json - {"type":"matchRepoDigestOrExact"} - ``` -- The identity in the signature must be in the same repository as the image identity. This is useful e.g. to pull an image using the `:latest` tag when the image is signed with a tag specifing an exact image version. - - ```json - {"type":"matchRepository"} - ``` -- The identity in the signature must exactly match a specified identity. - This is useful e.g. when locally mirroring images signed using their public identity. - - ```js - { - "type": "exactReference", - "dockerReference": docker_reference_value - } - ``` -- The identity in the signature must be in the same repository as a specified identity. - This combines the properties of `matchRepository` and `exactReference`. - - ```js - { - "type": "exactRepository", - "dockerRepository": docker_repository_value - } - ``` - -If the `signedIdentity` field is missing, it is treated as `matchRepoDigestOrExact`. - -*Note*: `matchExact`, `matchRepoDigestOrExact` and `matchRepository` can be only used if a Docker-like image identity is -provided by the transport. In particular, the `dir:` and `oci:` transports can be only -used with `exactReference` or `exactRepository`. - - - -## Examples - -It is *strongly* recommended to set the `default` policy to `reject`, and then -selectively allow individual transports and scopes as desired. - -### A reasonably locked-down system - -(Note that the `/*`…`*/` comments are not valid in JSON, and must not be used in real policies.) - -```js -{ - "default": [{"type": "reject"}], /* Reject anything not explicitly allowed */ - "transports": { - "docker": { - /* Allow installing images from a specific repository namespace, without cryptographic verification. - This namespace includes images like openshift/hello-openshift and openshift/origin. */ - "docker.io/openshift": [{"type": "insecureAcceptAnything"}], - /* Similarly, allow installing the “official” busybox images.
