 ## 1. Brief introduction

 
  - The daemon listens on `unix:///var/run/docker.sock` but you can

    [Bind Docker to another host/port or a Unix socket](../reference/commandline/dockerd.md#bind-docker-to-another-host-port-or-a-unix-socket).

  - The API tends to be REST. However, for some complex commands, like `attach`
    or `pull`, the HTTP connection is hijacked to transport `stdout`,
    `stdin` and `stderr`.
 

 ## 2. Errors

 The Engine API uses standard HTTP status codes to indicate the success or failure of the API call. The body of the response will be JSON in the following format:

 
     {
         "message": "page not found"
     }
 
 The status codes that are returned for each endpoint are specified in the endpoint documentation below.

 **Query parameters**:

 
 -   **all** – 1/True/true or 0/False/false, Show all containers.
         Only running containers are shown by default (i.e., this defaults to false)
 -   **limit** – Show `limit` last created
         containers, include non-running ones.
 -   **since** – Show only containers created since Id, include
         non-running ones.
 -   **before** – Show only containers created before Id, include
         non-running ones.
 -   **size** – 1/True/true or 0/False/false, Show the containers
         sizes
 -   **filters** - a JSON encoded value of the filters (a `map[string][]string`) to process on the containers list. Available filters:
   -   `exited=<int>`; -- containers with exit code of  `<int>` ;
   -   `status=`(`created`|`restarting`|`running`|`paused`|`exited`|`dead`)
   -   `label=key` or `label="key=value"` of a container label
   -   `isolation=`(`default`|`process`|`hyperv`)   (Windows daemon only)
   -   `ancestor`=(`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`)
   -   `before`=(`<container id>` or `<container name>`)
   -   `since`=(`<container id>` or `<container name>`)
   -   `volume`=(`<volume name>` or `<mount point destination>`)

   -   `network`=(`<network id>` or `<network name>`)

 **Status codes**:

 
 -   **200** – no error
 -   **400** – bad parameter
 -   **500** – server error

 -   **stream** – 1/True/true or 0/False/false, return stream.
         Default `false`.
 -   **stdin** – 1/True/true or 0/False/false, if `stream=true`, attach
         to `stdin`. Default `false`.
 -   **stdout** – 1/True/true or 0/False/false, if `logs=true`, return
         `stdout` log, if `stream=true`, attach to `stdout`. Default `false`.
 -   **stderr** – 1/True/true or 0/False/false, if `logs=true`, return
         `stderr` log, if `stream=true`, attach to `stderr`. Default `false`.
 

 **Status codes**:

 
 -   **101** – no error, hints proxy about hijacking
 -   **200** – no error, no upgrade header found
 -   **400** – bad parameter
 -   **404** – no such container

 -   **409** - container is paused

 -   **500** – server error
 

 **Stream details**:

 When using the TTY setting is enabled in
 [`POST /containers/create`
 ](#create-a-container),
 the stream is the raw data from the process PTY and client's `stdin`.
 When the TTY is disabled, then the stream is multiplexed to separate
 `stdout` and `stderr`.

 The format is a **Header** and a **Payload** (frame).

 **HEADER**

 The header contains the information which the stream writes (`stdout` or
 `stderr`). It also contains the size of the associated frame encoded in the
 last four bytes (`uint32`).

 It is encoded on the first eight bytes like this:

     header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}

 `STREAM_TYPE` can be:

 
 -   0: `stdin` (is written on `stdout`)
 -   1: `stdout`
 -   2: `stderr`
 

 `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of
 the `uint32` size encoded as big endian.

 **PAYLOAD**

 The payload is the raw stream.

 **IMPLEMENTATION**

 The simplest way to implement the Attach protocol is the following:

 
     1.  Read eight bytes.
     2.  Choose `stdout` or `stderr` depending on the first byte.
     3.  Extract the frame size from the last four bytes.
     4.  Read the extracted size and output it on the correct output.
     5.  Goto 1.

 #### Retrieving information about files and folders in a container

 
 `HEAD /containers/(id or name)/archive`
 
 See the description of the `X-Docker-Container-Path-Stat` header in the
 following section.
 

 #### Get an archive of a filesystem resource in a container

 
 `GET /containers/(id or name)/archive`
 

 Get a tar archive of a resource in the filesystem of container `id`.

 **Query parameters**:

 
 - **path** - resource in the container's filesystem to archive. Required.
 
     If not an absolute path, it is relative to the container's root directory.
     The resource specified by **path** must exist. To assert that the resource
     is expected to be a directory, **path** should end in `/` or  `/.`
     (assuming a path separator of `/`). If **path** ends in `/.` then this
     indicates that only the contents of the **path** directory should be
     copied. A symlink is always resolved to its target.
 

     > **Note**: It is not possible to copy certain system files such as resources
     > under `/proc`, `/sys`, `/dev`, and mounts created by the user in the
     > container.

 
 **Example request**:
 

     GET /v1.24/containers/8cce319429b2/archive?path=/root HTTP/1.1

 
 **Example response**:
 

     HTTP/1.1 200 OK
     Content-Type: application/x-tar
     X-Docker-Container-Path-Stat: eyJuYW1lIjoicm9vdCIsInNpemUiOjQwOTYsIm1vZGUiOjIxNDc0ODQwOTYsIm10aW1lIjoiMjAxNC0wMi0yN1QyMDo1MToyM1oiLCJsaW5rVGFyZ2V0IjoiIn0=

     {% raw %}

     {{ TAR STREAM }}

     {% endraw %}

 
 On success, a response header `X-Docker-Container-Path-Stat` will be set to a
 base64-encoded JSON object containing some filesystem header information about
 the archived resource. The above example value would decode to the following
 JSON object (whitespace added for readability):
 

 ```json
 {
     "name": "root",
     "size": 4096,
     "mode": 2147484096,
     "mtime": "2014-02-27T20:51:23Z",
     "linkTarget": ""
 }
 ```

 
 A `HEAD` request can also be made to this endpoint if only this information is
 desired.
 

 **Status codes**:

 
 - **200** - success, returns archive of copied resource
 - **400** - client error, bad parameter, details in JSON response body, one of:
     - must specify path parameter (**path** cannot be empty)
     - not a directory (**path** was asserted to be a directory but exists as a
       file)
 - **404** - client error, resource not found, one of:
     – no such container (container `id` does not exist)
     - no such file or directory (**path** does not exist)
 - **500** - server error
 

 #### Extract an archive of files or folders to a directory in a container

 
 `PUT /containers/(id or name)/archive`
 
 Upload a tar archive to be extracted to a path in the filesystem of container
 `id`.
 

 **Query parameters**:

 
 - **path** - path to a directory in the container
     to extract the archive's contents into. Required.
 
     If not an absolute path, it is relative to the container's root directory.
     The **path** resource must exist.
 - **noOverwriteDirNonDir** - If "1", "true", or "True" then it will be an error
     if unpacking the given content would cause an existing directory to be
     replaced with a non-directory and vice versa.
 
 **Example request**:
 

     PUT /v1.24/containers/8cce319429b2/archive?path=/vol1 HTTP/1.1

     Content-Type: application/x-tar
 

     {% raw %}

     {{ TAR STREAM }}

     {% endraw %}

 
 **Example response**:

 The response shows a single image `Id` associated with two repositories
 (`RepoTags`): `localhost:5000/test/busybox`: and `playdate`. A caller can use
 either of the `RepoTags` values `localhost:5000/test/busybox:latest` or
 `playdate:latest` to reference the image.
 
 You can also use `RepoDigests` values to reference an image. In this response,
 the array has only one reference and that is to the
 `localhost:5000/test/busybox` repository; the `playdate` repository has no
 digest. You can reference this digest using the value:
 `localhost:5000/test/busybox@sha256:cbbf2f9a99b47fc460d...`
 
 See the `docker run` and `docker build` commands for examples of digest and tag
 references on the command line.
 

 **Query parameters**:

 
 -   **all** – 1/True/true or 0/False/false, default false
 -   **filters** – a JSON encoded value of the filters (a map[string][]string) to process on the images list. Available filters:
   -   `dangling=true`
   -   `label=key` or `label="key=value"` of an image label

   -   `before`=(`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`)
   -   `since`=(`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`)

 -   **filter** - only return images with the specified name
 

 #### Build image from a Dockerfile

 
 `POST /build`
 
 Build an image from a Dockerfile
 
 **Example request**:
 

     POST /v1.24/build HTTP/1.1

     Content-Type: application/x-tar

     {% raw %}

     {{ TAR STREAM }}

     {% endraw %}

 
 **Example response**:
 
     HTTP/1.1 200 OK
     Content-Type: application/json
 

     {"stream": "Step 1/5..."}

     {"stream": "..."}
     {"error": "Error...", "errorDetail": {"code": 123, "message": "Error..."}}
 
 The input stream must be a `tar` archive compressed with one of the
 following algorithms: `identity` (no compression), `gzip`, `bzip2`, `xz`.
 
 The archive must include a build instructions file, typically called
 `Dockerfile` at the archive's root. The `dockerfile` parameter may be
 used to specify a different build instructions file. To do this, its value must be
 the path to the alternate build instructions file to use.
 
 The archive may include any number of other files,
 which are accessible in the build context (See the [*ADD build

 command*](../reference/builder.md#add)).

 The Docker daemon performs a preliminary validation of the `Dockerfile` before
 starting the build, and returns an error if the syntax is incorrect. After that,
 each instruction is run one-by-one until the ID of the new image is output.
 

 The build is canceled if the client drops the connection by quitting
 or being killed.
 

 **Query parameters**:

 -   **dockerfile** - Path within the build context to the `Dockerfile`. This is
         ignored if `remote` is specified and points to an external `Dockerfile`.

 -   **t** – A name and optional tag to apply to the image in the `name:tag` format.
         If you omit the `tag` the default `latest` value is assumed.
         You can provide one or more `t` parameters.

 -   **remote** – A Git repository URI or HTTP/HTTPS context URI. If the
         URI points to a single text file, the file's contents are placed into

         a file called `Dockerfile` and the image is built from that file. If
         the URI points to a tarball, the file is downloaded by the daemon and
         the contents therein used as the context for the build. If the URI
         points to a tarball and the `dockerfile` parameter is also specified,
         there must be a file with the corresponding path inside the tarball.

 -   **q** – Suppress verbose build output.
 -   **nocache** – Do not use the cache when building the image.
 -   **pull** - Attempt to pull the image even if an older image exists locally.
 -   **rm** - Remove intermediate containers after a successful build (default behavior).
 -   **forcerm** - Always remove intermediate containers (includes `rm`).
 -   **memory** - Set memory limit for build.
 -   **memswap** - Total memory (memory + swap), `-1` to enable unlimited swap.
 -   **cpushares** - CPU shares (relative weight).
 -   **cpusetcpus** - CPUs in which to allow execution (e.g., `0-3`, `0,1`).
 -   **cpuperiod** - The length of a CPU period in microseconds.
 -   **cpuquota** - Microseconds of CPU time that the container can get in a CPU period.
 -   **buildargs** – JSON map of string pairs for build-time variables. Users pass
         these values at build-time. Docker uses the `buildargs` as the environment
         context for command(s) run via the Dockerfile's `RUN` instruction or for
         variable expansion in other Dockerfile instructions. This is not meant for

         passing secret values. [Read more about the buildargs instruction](../reference/builder.md#arg)

 -   **shmsize** - Size of `/dev/shm` in bytes. The size must be greater than 0.  If omitted the system uses 64MB.

 -   **labels** – JSON map of string pairs for labels to set on the image.

 **Request Headers**:

 -   **Content-type** – Set to `"application/x-tar"`.

 -   **X-Registry-Config** – A base64-url-safe-encoded Registry Auth Config JSON
         object with the following structure:
 
             {
                 "docker.example.com": {
                     "username": "janedoe",
                     "password": "hunter2"
                 },
                 "https://index.docker.io/v1/": {
                     "username": "mobydock",
                     "password": "conta1n3rize14"
                 }
             }
 

     This object maps the hostname of a registry to an object containing the
     "username" and "password" for that registry. Multiple registries may
     be specified as the build may be based on an image requiring
     authentication to pull from any arbitrary registry. Only the registry
     domain name (and port if not the default "443") are required. However
     (for legacy reasons) the "official" Docker, Inc. hosted registry must
     be specified with both a "https://" prefix and a "/v1/" suffix even
     though Docker will prefer to use the v2 registry API.

 **Status codes**:

 
 -   **200** – no error
 -   **500** – server error
 

 #### Create an image

 
 `POST /images/create`
 
 Create an image either by pulling it from the registry or by importing it
 
 **Example request**:
 

     POST /v1.24/images/create?fromImage=busybox&tag=latest HTTP/1.1

 
 **Example response**:
 
     HTTP/1.1 200 OK
     Content-Type: application/json
 
     {"status": "Pulling..."}
     {"status": "Pulling", "progress": "1 B/ 100 B", "progressDetail": {"current": 1, "total": 100}}
     {"error": "Invalid..."}
     ...
 
 When using this endpoint to pull an image from the registry, the
 `X-Registry-Auth` header can be used to include
 a base64-encoded AuthConfig object.
 

 **Query parameters**:

 
 -   **fromImage** – Name of the image to pull. The name may include a tag or
         digest. This parameter may only be used when pulling an image.
         The pull is cancelled if the HTTP connection is closed.
 -   **fromSrc** – Source to import.  The value may be a URL from which the image
         can be retrieved or `-` to read the image from the request body.
         This parameter may only be used when importing an image.
 -   **repo** – Repository name given to an image when it is imported.
         The repo may include a tag. This parameter may only be used when importing
         an image.

 -   **tag** – Tag or digest. If empty when pulling an image, this causes all tags
         for the given image to be pulled.

 **Request Headers**:

 
 -   **X-Registry-Auth** – base64-encoded AuthConfig object, containing either login information, or a token
     - Credential based login:
 
         ```
     {
             "username": "jdoe",
             "password": "secret",

             "email": "jdoe@acme.com"

     }
         ```
 
     - Token based login:
 
         ```
     {

             "identitytoken": "9cbaf023786cd7..."

     }
         ```
 

 **Status codes**:

 
 -   **200** – no error

 -   **404** - repository does not exist or no read access

 -   **500** – server error

 #### Push an image on the registry

 
 `POST /images/(name)/push`
 
 Push the image `name` on the registry
 
 **Example request**:
 

     POST /v1.24/images/test/push HTTP/1.1

 
 **Example response**:
 
     HTTP/1.1 200 OK
     Content-Type: application/json

     {"error": "Invalid..."}
     ...
 
 If you wish to push an image on to a private registry, that image must already have a tag
 into a repository which references that registry `hostname` and `port`.  This repository name should
 then be used in the URL. This duplicates the command line's flow.
 
 The push is cancelled if the HTTP connection is closed.
 
 **Example request**:
 

     POST /v1.24/images/registry.acme.com:5000/test/push HTTP/1.1

 **Query parameters**:

 
 -   **tag** – The tag to associate with the image on the registry. This is optional.
 

 **Request Headers**:

             "password": "secret",
             "email": "jdoe@acme.com",
     }
         ```
 
     - Identity token based login:
 
         ```
     {
             "identitytoken": "9cbaf023786cd7..."

 `GET /images/(name)/get`
 
 Get a tarball containing all images and metadata for the repository specified
 by `name`.

 (and its parents) are returned. If `name` is an image ID, similarly only that
 image (and its parents) are returned, but with the exclusion of the
 'repositories' file in the tarball, as there were no image names referenced.
 
 See the [image tarball format](#image-tarball-format) for more details.

 #### Image tarball format

 
 An image tarball contains one directory per image layer (named using its long ID),
 each containing these files:
 
 - `VERSION`: currently `1.0` - the file format version
 - `json`: detailed layer information, similar to `docker inspect layer_id`
 - `layer.tar`: A tarfile containing the filesystem changes in this layer
 
 The `layer.tar` file contains `aufs` style `.wh..wh.aufs` files and directories
 for storing attribute changes and deletions.
 
 If the tarball defines a repository, the tarball should also include a `repositories` file at
 the root that contains a list of repository and tag names mapped to layer IDs.
 
 ```
 {"hello-world":
     {"latest": "565a9d68a73f6706862bfe8409a7f659776d4d60a8d096eb4a3cbce6999cc2a1"}
 }
 ```

 **JSON parameters**:

 
 - **Name** - The new network's name. this is a mandatory field

 - **CheckDuplicate** - Requests daemon to check for networks with same name. Defaults to `false`.
     Since Network is primarily keyed based on a random ID and not on the name, 
     and network name is strictly a user-friendly alias to the network 
     which is uniquely identified using ID, there is no guaranteed way to check for duplicates. 
     This parameter CheckDuplicate is there to provide a best effort checking of any networks 
     which has the same name but it is not guaranteed to catch all name collisions.

 - **Driver** - Name of the network driver plugin to use. Defaults to `bridge` driver
 - **Internal** - Restrict external access to the network
 - **IPAM** - Optional custom IP scheme for the network

   - **Driver** - Name of the IPAM driver to use. Defaults to `default` driver
   - **Config** - List of IPAM configuration options, specified as a map:
       `{"Subnet": <CIDR>, "IPRange": <CIDR>, "Gateway": <IP address>, "AuxAddress": <device_name:IP address>}`
   - **Options** - Driver-specific options, specified as a map: `{"option":"value" [,"option2":"value2"]}`

 - **EnableIPv6** - Enable IPv6 on the network
 - **Options** - Network specific options to be used by the drivers

 - **Labels** - Labels to set on the network, specified as a map: `{"key":"value" [,"key2":"value2"]}`

 ## 4. Going further

 ### 4.1 Inside `docker run`

 
 As an example, the `docker run` command line makes the following API calls:
 
 - Create the container
 
 - If the status code is 404, it means the image doesn't exist:
     - Try to pull it.
     - Then, retry to create the container.
 
 - Start the container.
 
 - If you are not in detached mode:
 - Attach to the container, using `logs=1` (to have `stdout` and
       `stderr` from the container's start) and `stream=1`
 
 - If in detached mode or only `stdin` is attached, display the container's id.
 

 ### 4.2 Hijacking

 
 In this version of the API, `/attach`, uses hijacking to transport `stdin`,
 `stdout`, and `stderr` on the same socket.
 
 To hint potential proxies about connection hijacking, Docker client sends
 connection upgrade headers similarly to websocket.
 
     Upgrade: tcp
     Connection: Upgrade
 
 When Docker daemon detects the `Upgrade` header, it switches its status code
