<h1>docker manifest</h1> <p><br></p> <p>Manage Docker image manifests and manifest lists</p> <blockquote class="important"> <p>This command is experimental.</p> <p><a href="../cli/index#experimental-features">Experimental features</a> are intended for testing and feedback as their functionality or UX may change between releases without warning or can be removed entirely in a future release.</p> </blockquote> <h2 id="usage">Usage</h2> <div class="highlight"><pre class="highlight" data-language="">$ docker manifest COMMAND COMMAND
</pre></div> <h2 id="description">Description</h2> <p name="extended-description">The <code class="language-plaintext highlighter-rouge">docker manifest</code> command by itself performs no action. In order to operate on a manifest or manifest list, one of the subcommands must be used.</p> <p>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.</p> <p>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 <code class="language-plaintext highlighter-rouge">docker pull</code> and <code class="language-plaintext highlighter-rouge">docker run</code> commands, for example.</p> <p>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.</p> <h3 id="manifest-inspect">manifest inspect</h3> <div class="highlight"><pre class="highlight" data-language="">$ 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
</pre></div> <h3 id="manifest-create">manifest create</h3> <div class="highlight"><pre class="highlight" data-language="">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
</pre></div> <h3 id="manifest-annotate">manifest annotate</h3> <div class="highlight"><pre class="highlight" data-language="">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
</pre></div> <h3 id="manifest-push">manifest push</h3> <div class="highlight"><pre class="highlight" data-language="">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
</pre></div> <h3 id="working-with-insecure-registries">Working with insecure registries</h3> <p>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 <code class="language-plaintext highlighter-rouge">docker manifest</code> commands have an <code class="language-plaintext highlighter-rouge">--insecure</code> flag. For each transaction, such as a <code class="language-plaintext highlighter-rouge">create</code>, which queries a registry, the <code class="language-plaintext highlighter-rouge">--insecure</code> 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 <code class="language-plaintext highlighter-rouge">manifest push</code> to an insecure registry, the <code class="language-plaintext highlighter-rouge">--insecure</code> 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.</p> <p>For example uses of this command, refer to the <a href="#examples">examples section</a> below.</p> <h2 id="examples">Examples</h2> <h3 id="inspect-an-images-manifest-object">Inspect an image’s manifest object</h3> <div class="highlight"><pre class="highlight" data-language="">$ docker manifest inspect hello-world

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.</p> <p>After you have created your local copy of the manifest list, you may optionally <code class="language-plaintext highlighter-rouge">annotate</code> it. Annotations allowed are the architecture and operating system (overriding the image’s current values), os features, and an architecture variant.</p> <p>Finally, you need to <code class="language-plaintext highlighter-rouge">push</code> your manifest list to the desired registry.
