## 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.
|

|
|
|
|
### Working with insecure registries
|
|
|
|
The manifest command interacts solely with a Docker 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
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ docker manifest create 45.55.81.106:5000/coolapp:v1 \
|
|
45.55.81.106:5000/coolapp-ppc64le-linux:v1 \

|

|
|

|
|
Created manifest list 45.55.81.106:5000/coolapp:v1
|
|
```
|
|
|
|
```bash
|
|
$ docker manifest annotate 45.55.81.106:5000/coolapp:v1 45.55.81.106:5000/coolapp-arm-linux --arch arm
|
|
```
|
|
|
|
```bash
|
|
$ docker manifest push 45.55.81.106:5000/coolapp:v1

|

### Push to an insecure registry
|
|
|
|
Here is an example of creating and pushing a manifest list using a known insecure registry.
|
|
|
|
```
|
|
$ 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 that 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`.
