Docker Engine API v1.51 documentation
GET /images/json now sets the value of Containers field for all images to the count of containers using the image. This field was previously always -1.Docker Engine API v1.50 documentation
GET /info now includes a DiscoveredDevices field. This is an array of DeviceInfo objects, each providing details about a device discovered by a device driver. Currently only the CDI device driver is supported.DELETE /images/{name} now supports a platforms query parameter. It accepts an array of JSON-encoded OCI Platform objects, allowing for selecting specific platforms to delete content for.BridgeNfIptables and BridgeNfIp6tables fields in the GET /info response were deprecated in API v1.48, and are now omitted in API v1.50.GET /images/{name}/json no longer returns the following Config fields; Hostname, Domainname, AttachStdin, AttachStdout, AttachStderr Tty, OpenStdin, StdinOnce, Image, NetworkDisabled (already omitted unless set), MacAddress (already omitted unless set), StopTimeout (already omitted unless set). These additional fields were included in the response due to an implementation detail but not part of the image's Configuration. These fields were marked deprecated in API v1.46, and are now omitted. Older versions of the API still return these fields, but they are always empty.Docker Engine API v1.49 documentation
GET /images/{name}/json now supports a platform parameter (JSON encoded OCI Platform type) allowing to specify a platform of the multi-platform image to inspect. This option is mutually exclusive with the manifests option.GET /info now returns a FirewallBackend containing information about the daemon's firewalling configuration.AllowNondistributableArtifactsCIDRs and AllowNondistributableArtifactsHostnames fields in the RegistryConfig struct in the GET /info response are omitted in API v1.49.ContainerdCommit.Expected, RuncCommit.Expected, and InitCommit.Expected fields in the GET /info endpoint were deprecated in API v1.48, and are now omitted in API v1.49.Docker Engine API v1.48 documentation
POST /images/create, POST /images/{name}/push, and POST /build are deprecated. These fields were marked deprecated in API v1.4 (docker v0.6.0) and API v1.8 (docker v0.7.1) respectively, but still returned. These fields will be left empty or will be omitted in a future API version. Users should use the information in the errorDetail and progressDetail fields instead.AllowNondistributableArtifactsCIDRs and AllowNondistributableArtifactsHostnames fields in the RegistryConfig struct in the GET /info response will now always be null and will be omitted in API v1.49.BridgeNfIptables and BridgeNfIp6tables fields in the GET /info response are now always be false and will be omitted in API v1.49. The netfilter module is now loaded on-demand, and no longer during daemon startup, making these fields obsolete.GET /images/{name}/history now supports a platform parameter (JSON encoded OCI Platform type) that allows to specify a platform to show the history of.POST /images/{name}/load and GET /images/{name}/get now support a platform parameter (JSON encoded OCI Platform type) that allows to specify a platform to load/save. Not passing this parameter will result in loading/saving the full multi-platform image.POST /containers/create now includes a warning in the response when setting the container-wide Config.VolumeDriver option in combination with volumes defined through Mounts because the VolumeDriver option has no effect on those volumes. This warning was previously generated by the CLI, but now moved to the daemon so that other clients can also get this warning.POST /containers/create now supports Mount of type image for mounting an image inside a container.ContainerdCommit.Expected, RuncCommit.Expected, and InitCommit.Expected fields in the GET /info endpoint are deprecated and will be omitted in API v1.49.Sysctls in HostConfig (top level --sysctl settings) for eth0 are no longer migrated to DriverOpts, as described in the changes for v1.46.GET /images/json and GET /images/{name}/json responses now include Descriptor field, which contains an OCI descriptor of the image target. The new field will only be populated if the daemon provides a multi-platform image store. WARNING: This is experimental and may change at any time without any backward compatibility.GET /images/{name}/json response now will return the Manifests field containing information about the sub-manifests contained in the image index. This includes things like platform-specific manifests and build attestations. The new field will only be populated if the request also sets the manifests query parameter to true. This acts the same as in the GET /images/json endpoint. WARNING: This is experimental and may change at any time without any backward compatibility.GET /containers/{name}/json now returns an ImageManifestDescriptor field containing the OCI descriptor of the platform-specific image manifest of the image that was used to create the container. This field is only populated if the daemon provides a multi-platform image store.POST /networks/create now has an EnableIPv4 field. Setting it to false disables IPv4 IPAM for the network. It can only be set to false if the daemon has experimental features enabled.GET /networks/{id} now returns an EnableIPv4 field showing whether the network has IPv4 IPAM enabled.POST /networks/{id}/connect and POST /containers/create now accept a GwPriority field in EndpointsConfig. This value is used to determine which network endpoint provides the default gateway for the container. The endpoint with the highest priority is selected. If multiple endpoints have the same priority, endpoints are sorted lexicographically by their network name, and the one that sorts first is picked.GET /containers/json now returns a GwPriority field in NetworkSettings for each network endpoint.GET /debug/vars, GET /debug/pprof/, GET /debug/pprof/cmdline, GET /debug/pprof/profile, GET /debug/pprof/symbol, GET /debug/pprof/trace, GET /debug/pprof/{name}) are now also accessible through the versioned-API paths (/v<API-version>/<endpoint>).POST /build/prune renames keep-bytes to reserved-space and now supports additional prune parameters max-used-space and min-free-space.GET /containers/json now returns an ImageManifestDescriptor field matching the same field in /containers/{name}/json. This field is only populated if the daemon provides a multi-platform image store.Docker Engine API v1.47 documentation
GET /images/json response now includes Manifests field, which contains information about the sub-manifests included in the image index. This includes things like platform-specific manifests and build attestations. The new field will only be populated if the request also sets the manifests query parameter to true. WARNING: This is experimental and may change at any time without any backward compatibility.GET /info no longer includes warnings when bridge-nf-call-iptables or bridge-nf-call-ip6tables are disabled when the daemon was started. The br_netfilter module is now attempted to be loaded when needed, making those warnings inaccurate. This change is not versioned, and affects all API versions if the daemon has this patch.Docker Engine API v1.46 documentation
GET /info now includes a Containerd field containing information about the location of the containerd API socket and containerd namespaces used by the daemon to run containers and plugins.POST /containers/create field NetworkingConfig.EndpointsConfig.DriverOpts, and POST /networks/{id}/connect field EndpointsConfig.DriverOpts, now support label com.docker.network.endpoint.sysctls for setting per-interface sysctls. The value is a comma separated list of sysctl assignments, the interface name must be "IFNAME". For example, to set net.ipv4.config.eth0.log_martians=1, use net.ipv4.config.IFNAME.log_martians=1. In API versions up-to 1.46, top level --sysctl settings for eth0 will be migrated to DriverOpts when possible. This automatic migration will be removed in a future release.GET /containers/json now returns the annotations of containers.POST /images/{name}/push now supports a platform parameter (JSON encoded OCI Platform type) that allows selecting a specific platform manifest from the multi-platform image.POST /containers/create now takes Options as part of HostConfig.Mounts.TmpfsOptions to set options for tmpfs mounts.POST /services/create now takes Options as part of ContainerSpec.Mounts.TmpfsOptions, to set options for tmpfs mounts.GET /events now supports image create event that is emitted when a new image is built regardless if it was tagged or not.GET /images/{name}/json response
The Config field returned by this endpoint (used for "image inspect") returns additional fields that are not part of the image's configuration and not part of the Docker Image Spec and the OCI Image Spec.
These additional fields are included in the response, due to an implementation detail, where the api/types.ImageInspec type used for the response is using the container.Config type.
The container.Config type is a superset of the image config, and while the image's Config is used as a template for containers created from the image, the additional fields are set at runtime (from options passed when creating the container) and not taken from the image Config.
These fields are never set (and always return the default value for the type), but are not omitted in the response when left empty. As these fields were not intended to be part of the image configuration response, they are deprecated, and will be removed from the API.
The following fields are currently included in the API response, but are not part of the underlying image's Config, and deprecated:
HostnameDomainnameAttachStdinAttachStdoutAttachStderrTtyOpenStdinStdinOnceImageNetworkDisabled (already omitted unless set)MacAddress (already omitted unless set)StopTimeout (already omitted unless set)POST /services/create and POST /services/{id}/update now support OomScoreAdjDocker Engine API v1.45 documentation
POST /containers/create now supports VolumeOptions.Subpath which allows a subpath of a named volume to be mounted.POST /images/search will always assume a false value for the is-automated field. Consequently, searching for is-automated=true will yield no results, while is-automated=false will be a no-op.GET /images/{name}/json no longer includes the Container and ContainerConfig fields. To access image configuration, use Config field instead.Aliases field returned in calls to GET /containers/{name:.*}/json no longer contains the short container ID, but instead will reflect exactly the values originally submitted to the POST /containers/create endpoint. The newly introduced DNSNames should now be used instead when short container IDs are needed.Docker Engine API v1.44 documentation
/images/json now accepts an until filter. This accepts a timestamp and lists all images created before it. The <timestamp> can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the daemon machineâs time. This change is not versioned, and affects all API versions if the daemon has this patch.VirtualSize field in the GET /images/{name}/json, GET /images/json, and GET /system/df responses is now omitted. Use the Size field instead, which contains the same information.is_automated field in the GET /images/search response has been deprecated and will always be set to false in the future because Docker Hub is deprecating the is_automated field in its search API. The deprecation is not versioned, and applies to all API versions.is-automated filter for the GET /images/search endpoint. The is_automated field has been deprecated by Docker Hub's search API. Consequently, searching for is-automated=true will yield no results. The deprecation is not versioned, and applies to all API versions.POST /containers/create, GET /containers/{id}/json, and GET /containers/json now supports BindOptions.ReadOnlyNonRecursive and BindOptions.ReadOnlyForceRecursive to customize the behavior.POST /containers/create now accepts a HealthConfig.StartInterval to set the interval for health checks during the start period.GET /info now includes a CDISpecDirs field indicating the configured CDI specifications directories. The use of the applied setting requires the daemon to have experimental enabled, and for non-experimental daemons an empty list is always returned.POST /networks/create now returns a 400 if the IPAMConfig has invalid values. Note that this change is unversioned and applied to all API versions on daemon that support version 1.44.POST /networks/create with a duplicated name now fails systematically. As such, the CheckDuplicate field is now deprecated. Note that this change is unversioned and applied to all API versions on daemon that support version 1.44.POST /containers/create now accepts multiple EndpointSettings in NetworkingConfig.EndpointSettings.POST /containers/create and POST /networks/{id}/connect will now catch validation errors that were previously only returned during POST /containers/{id}/start. These endpoints will also return the full set of validation errors they find, instead of returning only the first one. Note that this change is unversioned and applies to all API versions.POST /services/create and POST /services/{id}/update now accept Seccomp and AppArmor fields in the ContainerSpec.Privileges object. This allows some configuration of Seccomp and AppArmor in Swarm services.MacAddress field has been added to NetworkSettings.EndpointSettings on POST /containers/create, and to EndpointConfig on POST /networks/{id}/connect. The container-wide MacAddress field in Config, on POST /containers/create, is now deprecated.Networks in the POST /services/create and POST /services/{id}/update requests is now deprecated. You should instead use the field TaskTemplate.Networks.Container and ContainerConfig fields in the GET /images/{name}/json response are deprecated and will no longer be included in API v1.45.GET /info now includes status properties in Runtimes.DNSNames and containing all non-fully qualified DNS names a container takes on a specific network has been added to GET /containers/{name:.*}/json.Aliases field returned in calls to GET /containers/{name:.*}/json in v1.44 and older versions contains the short container ID. This will change in the next API version, v1.45. Starting with that API version, this specific value will be removed from the Aliases field such that this field will reflect exactly the values originally submitted to the POST /containers/create endpoint. The newly introduced DNSNames should now be used instead.HairpinMode, LinkLocalIPv6Address, LinkLocalIPv6PrefixLen, SecondaryIPAddresses, SecondaryIPv6Addresses available in NetworkSettings when calling GET /containers/{id}/json are deprecated and will be removed in a future release. You should instead look for the default network in NetworkSettings.Networks.GET /images/{id}/json omits the Created field (previously it was 0001-01-01T00:00:00Z) if the Created field is missing from the image config.Docker Engine API v1.43 documentation
POST /containers/create now accepts Annotations as part of HostConfig. Can be used to attach arbitrary metadata to the container, which will also be passed to the runtime when the container is started.GET /images/json no longer includes hardcoded <none>:<none> and <none>@<none> in RepoTags andRepoDigests for untagged images. In such cases, empty arrays will be produced instead.VirtualSize field in the GET /images/{name}/json, GET /images/json, and GET /system/df responses is deprecated and will no longer be included in API v1.44. Use the Size field instead, which contains the same information.GET /info now includes no-new-privileges in the SecurityOptions string list when this option is enabled globally. This change is not versioned, and affects all API versions if the daemon has this patch.Docker Engine API v1.42 documentation
Removed the BuilderSize field on the GET /system/df endpoint. This field was introduced in API 1.31 as part of an experimental feature, and no longer used since API 1.40. Use field BuildCache instead to track storage used by the builder component.
POST /containers/{id}/stop and POST /containers/{id}/restart now accept a signal query parameter, which allows overriding the container's default stop- signal.
GET /images/json now accepts query parameter shared-size. When set true, images returned will include SharedSize, which provides the size on disk shared with other images present on the system.
GET /system/df now accepts query parameter type. When set, computes and returns data only for the specified object type. The parameter can be specified multiple times to select several object types. Supported values are: container, image, volume, build-cache.
GET /system/df can now be used concurrently. If a request is made while a previous request is still being processed, the request will receive the result of the already running calculation, once completed. Previously, an error (a disk usage operation is already running) would be returned in this situation. This change is not versioned, and affects all API versions if the daemon has this patch.
The POST /images/create now supports both the operating system and architecture that is passed through the platform query parameter when using the fromSrc option to import an image from an archive. Previously, only the operating system was used and the architecture was ignored. If no platform option is set, the host's operating system and architecture as used as default. This change is not versioned, and affects all API versions if the daemon has this patch.
The POST /containers/{id}/wait endpoint now returns a 400 status code if an invalid condition is provided (on API 1.30 and up).
Removed the KernelMemory field from the POST /containers/create and POST /containers/{id}/update endpoints, any value it is set to will be ignored on API version v1.42 and up. Older API versions still accept this field, but may take no effect, depending on the kernel version and OCI runtime in use.
GET /containers/{id}/json now omits the KernelMemory and KernelMemoryTCP if they are not set.
GET /info now omits the KernelMemory and KernelMemoryTCP if they are not supported by the host or host's configuration (if cgroups v2 are in use).
GET /_ping and HEAD /_ping now return Builder-Version by default. This header contains the default builder to use, and is a recommendation as advertised by the daemon. However, it is up to the client to choose which builder to use.
The default value on Linux is version "2" (BuildKit), but the daemon can be configured to recommend version "1" (classic Builder). Windows does not yet support BuildKit for native Windows images, and uses "1" (classic builder) as a default.
This change is not versioned, and affects all API versions if the daemon has this patch.
GET /_ping and HEAD /_ping now return a Swarm header, which allows a client to detect if Swarm is enabled on the daemon, without having to call additional endpoints. This change is not versioned, and affects all API versions if the daemon has this patch. Clients must consider this header "optional", and fall back to using other endpoints to get this information if the header is not present.
The Swarm header can contain one of the following values:
POST /containers/create for Windows containers now accepts a new syntax in HostConfig.Resources.Devices.PathOnHost. As well as the existing class/<GUID> syntax, <IDType>://<ID> is now recognised. Support for specific <IDType> values depends on the underlying implementation and Windows version. This change is not versioned, and affects all API versions if the daemon has this patch.
GET /containers/{id}/attach, GET /exec/{id}/start, GET /containers/{id}/logs GET /services/{id}/logs and GET /tasks/{id}/logs now set Content-Type header to application/vnd.docker.multiplexed-stream when a multiplexed stdout/stderr stream is sent to client, application/vnd.docker.raw-stream otherwise.
POST /volumes/create now accepts a new ClusterVolumeSpec to create a cluster volume (CNI). This option can only be used if the daemon is a Swarm manager. The Volume response on creation now also can contain a ClusterVolume field with information about the created volume.
The BuildCache.Parent field, as returned by GET /system/df is deprecated and is now omitted. API versions before v1.42 continue to include this field.
GET /system/df now includes a new Parents field, for "build-cache" records, which contains a list of parent IDs for the build-cache record.
Volume information returned by GET /volumes/{name}, GET /volumes and GET /system/df can now contain a ClusterVolume if the volume is a cluster volume (requires the daemon to be a Swarm manager).
The Volume type, as returned by Added new ClusterVolume` fields
Added a new PUT /volumes{name} endpoint to update cluster volumes (CNI). Cluster volumes are only supported if the daemon is a Swarm manager.
GET /containers/{name}/attach/ws endpoint now accepts stdin, stdout and stderr query parameters to only attach to configured streams.
NOTE: These parameters were documented before in older API versions, but not actually supported. API versions before v1.42 continue to ignore these parameters and default to attaching to all streams. To preserve the pre-v1.42 behavior, set all three query parameters (?stdin=1,stdout=1,stderr=1).
POST /containers/create on Linux now respects the HostConfig.ConsoleSize property. Container is immediately created with the desired terminal size and clients no longer need to set the desired size on their own.
POST /containers/create allow to set CreateMountpoint for host path to be created if missing. This brings parity with Binds
POST /containers/create rejects request if BindOptions|VolumeOptions|TmpfsOptions is set with a non-matching mount Type.
POST /containers/{id}/exec now accepts an optional ConsoleSize parameter. It allows to set the console size of the executed process immediately when it's created.
POST /volumes/prune will now only prune "anonymous" volumes (volumes which were not given a name) by default. A new filter parameter all can be set to a truth-y value (true, 1) to get the old behavior.
Docker Engine API v1.41 documentation
GET /events now returns prune events after pruning resources have completed. Prune events are returned for container, network, volume, image, and builder, and have a reclaimed attribute, indicating the amount of space reclaimed (in bytes).
GET /info now returns a CgroupVersion field, containing the cgroup version.
GET /info now returns a DefaultAddressPools field, containing a list of custom default address pools for local networks, which can be specified in the daemon.json file or --default-address-pool dockerd option.
POST /services/create and POST /services/{id}/update now supports BindOptions.NonRecursive.
The ClusterStore and ClusterAdvertise fields in GET /info are deprecated and are now omitted if they contain an empty value. This change is not versioned, and affects all API versions if the daemon has this patch.
The filter (singular) query parameter, which was deprecated in favor of the filters option in Docker 1.13, has now been removed from the GET /images/json endpoint. The parameter remains available when using API version 1.40 or below.

POST /containers/create now accepts a platform query parameter in the format os[/arch[/variant]].
When set, the daemon checks if the requested image is present in the local image cache with the given OS and Architecture, and otherwise returns a 404 status.
If the option is not set, the host's native OS and Architecture are used to look up the image in the image cache. However, if no platform is passed and the given image does exist in the local image cache, but its OS or architecture do not match, the container is created with the available image, and a warning is added to the Warnings field in the response, for example;
WARNING: The requested image's platform (linux/arm64/v8) does not
match the detected host platform (linux/amd64) and no
specific platform was requested
POST /containers/create on Linux now accepts the HostConfig.CgroupnsMode property. Set the property to host to create the container in the daemon's cgroup namespace, or private to create the container in its own private cgroup namespace. The per-daemon default is host, and can be changed by using theCgroupNamespaceMode daemon configuration parameter.
GET /info now returns an OSVersion field, containing the operating system's version. This change is not versioned, and affects all API versions if the daemon has this patch.
GET /info no longer returns the SystemStatus field if it does not have a value set. This change is not versioned, and affects all API versions if the daemon has this patch.

This option deprecates the fluentd-async-connect option, which remains functional, but will be removed in a future release. Users are encouraged to use the fluentd-async option going forward. This change is not versioned, and affects all API versions if the daemon has this patch.POST /containers/create now accepts a fluentd-request-ack option in HostConfig.LogConfig.Config when using the Fluentd logging driver. If enabled, the Fluentd logging driver sends the chunk option with a unique ID. The server will respond with an acknowledgement. This option improves the reliability of the message transmission.
