# manifest

<!---MARKER_GEN_START-->

The **docker manifest** command has subcommands for managing image manifests and
manifest lists. A manifest list allows you to use one name to refer to the same image
built for multiple architectures.

To see help for a subcommand, use:

    docker manifest CMD --help

For full details on using docker manifest lists, see the registry v2 specification.

## Description

The `docker manifest` command by itself performs no action. In order to operate
on a manifest or manifest list, one of the subcommands must be used.

A single manifest is information about an image, such as layers, size, and digest.
The docker manifest command also gives users additional information such as the os
and architecture an image was built for.

A manifest list is a list of image layers that is created by specifying one or
more (ideally more than one) image names. It can then be used in the same way as
an image name in `docker pull` and `docker run` commands, for example.

Ideally a manifest list is created from images that are identical in function for
different os/arch combinations. For this reason, manifest lists are often referred
to as "multi-arch images". However, a user could create a manifest list that points
to two images -- one for windows on amd64, and one for darwin on amd64.

### manifest inspect

```console
$ docker manifest inspect --help

Usage:  docker manifest inspect [OPTIONS] [MANIFEST_LIST] MANIFEST

Display an image manifest, or manifest list

Options:
      --help       Print usage
      --insecure   Allow communication with an insecure registry
  -v, --verbose    Output additional info including layers and platform
```

### manifest create

```console
Usage:  docker manifest create MANIFEST_LIST MANIFEST [MANIFEST...]

Create a local manifest list for annotating and pushing to a registry

Options:
  -a, --amend      Amend an existing manifest list
      --insecure   Allow communication with an insecure registry
      --help       Print usage
```

### manifest annotate

```console
Usage:  docker manifest annotate [OPTIONS] MANIFEST_LIST MANIFEST

Add additional information to a local image manifest

Options:
      --arch string               Set architecture
      --help                      Print usage
      --os string                 Set operating system
      --os-version string         Set operating system version
      --os-features stringSlice   Set operating system feature
      --variant string            Set architecture variant

```

### manifest push

```console
Usage:  docker manifest push [OPTIONS] MANIFEST_LIST

Push a manifest list to a repository

Options:
      --help       Print usage
      --insecure   Allow push to an insecure registry
  -p, --purge      Remove the local manifest list after push
```

### Working with insecure registries

The manifest command interacts solely with a registry. Because of this,
it has no way to query the engine for the list of allowed insecure registries.
To allow the CLI to interact with an insecure registry, some `docker manifest`
commands have an `--insecure` flag. For each transaction, such as a `create`,
which queries a registry, the `--insecure` flag must be specified. This flag
tells the CLI that this registry call may ignore security concerns like missing
or self-signed certificates. Likewise, on a `manifest push` to an insecure
registry, the `--insecure` flag must be specified. If this is not used with an
insecure registry, the manifest command fails to find a registry that meets the
default requirements.

## Examples

### Inspect an image's manifest object

```console
$ docker manifest inspect hello-world
{
        "schemaVersion": 2,
        "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
        "config": {
                "mediaType": "application/vnd.docker.container.image.v1+json",
                "size": 1520,
                "digest": "sha256:1815c82652c03bfd8644afda26fb184f2ed891d921b20a0703b46768f9755c57"
        },
        "layers": [
                {
                        "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
                        "size": 972,
                        "digest": "sha256:b04784fba78d739b526e27edc02a5a8cd07b1052e9283f5fc155828f4b614c28"
                }
        ]
}
```

### Inspect an image's manifest and get the os/arch info

The `docker manifest inspect` command takes an optional `--verbose` flag
that gives you the image's name (Ref), and architecture and os (Platform).

Just as with other docker commands that take image names, you can refer to an image with or
without a tag, or by digest (e.g. `hello-world@sha256:f3b3b28a45160805bb16542c9531888519430e9e6d6ffc09d72261b0d26ff74f`).

Here is an example of inspecting an image's manifest with the `--verbose` flag:

```console
$ docker manifest inspect --verbose hello-world
{
        "Ref": "docker.io/library/hello-world:latest",
        "Digest": "sha256:f3b3b28a45160805bb16542c9531888519430e9e6d6ffc09d72261b0d26ff74f",
        "SchemaV2Manifest": {
                "schemaVersion": 2,
                "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
                "config": {
                        "mediaType": "application/vnd.docker.container.image.v1+json",
                        "size": 1520,
                        "digest": "sha256:1815c82652c03bfd8644afda26fb184f2ed891d921b20a0703b46768f9755c57"
                },
                "layers": [
                        {
                                "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
                                "size": 972,
                                "digest": "sha256:b04784fba78d739b526e27edc02a5a8cd07b1052e9283f5fc155828f4b614c28"
                        }
                ]
        },
        "Platform": {
                "architecture": "amd64",
                "os": "linux"
        }
}
```

### Create and push a manifest list

To create a manifest list, you first `create` the manifest list locally by
specifying the constituent images you would like to have included in your
manifest list. Keep in mind that this is pushed to a registry, so if you want to
push to a registry other than the docker registry, you need to create your
manifest list with the registry name or IP and port.
This is similar to tagging an image and pushing it to a foreign registry.

After you have created your local copy of the manifest list, you may optionally
`annotate` it. Annotations allowed are the architecture and operating system
(overriding the image's current values), os features, and an architecture variant.

Finally, you need to `push` your manifest list to the desired registry. Below are
descriptions of these three commands, and an example putting them all together.

```console
$ docker manifest create 45.55.81.106:5000/coolapp:v1 \
    45.55.81.106:5000/coolapp-ppc64le-linux:v1 \
    45.55.81.106:5000/coolapp-arm-linux:v1 \
    45.55.81.106:5000/coolapp-amd64-linux:v1 \
    45.55.81.106:5000/coolapp-amd64-windows:v1

Created manifest list 45.55.81.106:5000/coolapp:v1
```

```console
$ docker manifest annotate 45.55.81.106:5000/coolapp:v1 45.55.81.106:5000/coolapp-arm-linux --arch arm
```

### Push to an insecure registry

Here is an example of creating and pushing a manifest list using a known
insecure registry.

```console
$ docker manifest create --insecure myprivateregistry.mycompany.com/repo/image:1.0 \
    myprivateregistry.mycompany.com/repo/image-linux-ppc64le:1.0 \
    myprivateregistry.mycompany.com/repo/image-linux-s390x:1.0 \
    myprivateregistry.mycompany.com/repo/image-linux-arm:1.0 \
    myprivateregistry.mycompany.com/repo/image-linux-armhf:1.0 \
    myprivateregistry.mycompany.com/repo/image-windows-amd64:1.0 \
    myprivateregistry.mycompany.com/repo/image-linux-amd64:1.0

$ docker manifest push --insecure myprivateregistry.mycompany.com/repo/image:tag
```

> **Note**
>
> The `--insecure` flag is not required to annotate a manifest list,
> since annotations are to a locally-stored copy of a manifest list. You may also
> skip the `--insecure` flag if you are performing a `docker manifest inspect`
> on a locally-stored manifest list. Be sure to keep in mind that locally-stored
> manifest lists are never used by the engine on a `docker pull`.
