| # Docker Remote API v1.22 |
| |
| ## 1. Brief introduction |
| |
| - The Remote API has replaced `rcli`. |
| - The daemon listens on `unix:///var/run/docker.sock` but you can |
| [Bind Docker to another host/port or a Unix socket](../../quickstart.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`. |
| - When the client API version is newer than the daemon's, these calls return an HTTP |
| `400 Bad Request` error message. |

| `json-file` logging driver. |
| - **CgroupParent** - Path to `cgroups` under which the container's `cgroup` is created. If the path is not absolute, the path is considered to be relative to the `cgroups` path of the init process. Cgroups are created if they do not already exist. |
| - **VolumeDriver** - Driver that this container users to mount volumes. |
| - **ShmSize** - Size of `/dev/shm` in bytes. The size must be greater than 0. If omitted the system uses 64MB. |
| |
| Query Parameters: |
| |
| - **name** – Assign the specified name to the container. Must |
| match `/?[a-zA-Z0-9_-]+`. |
| |
| Status Codes: |
| |
| - **201** – no error |
| - **404** – no such container |

| |
| **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 an 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 /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= |
| |
| {{ TAR STREAM }} |
| |
| 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): |
| |
| { |
| "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 /containers/8cce319429b2/archive?path=/vol1 HTTP/1.1 |
| Content-Type: application/x-tar |
| |
| {{ TAR STREAM }} |
| |
| **Example response**: |
| |
| HTTP/1.1 200 OK |
| |
| Status Codes: |
| |
| - **200** – the content was extracted successfully |
| - **400** - client error, bad parameter, details in JSON response body, one of: |
| - must specify path parameter (**path** cannot be empty) |
| - not a directory (**path** should be a directory but exists as a file) |
| - unable to overwrite existing directory with non-directory |
| (if **noOverwriteDirNonDir**) |
| - unable to overwrite existing non-directory with directory |
| (if **noOverwriteDirNonDir**) |
| - **403** - client error, permission denied, the volume |
| or container rootfs is marked as read-only. |
| - **404** - client error, resource not found, one of: |

| ] |
| |
| 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 |
| - **filter** - only return images with the specified name |
| |
| ### Build image from a Dockerfile |
| |
| `POST /build` |
| |
| Build an image from a Dockerfile |
| |
| **Example request**: |
| |
| POST /build HTTP/1.1 |
| |
| {{ TAR STREAM }} |
| |
| **Example response**: |
| |
| HTTP/1.1 200 OK |
| Content-Type: application/json |
| |
| {"stream": "Step 1..."} |
| {"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#dockerbuilder)). |
| |
| 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 individual filename. |
| - **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 URI build source. If the |
| URI specifies a filename, the file's contents are placed into a file |
| called `Dockerfile`. |
| - **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. |
| |
| Request Headers: |
| |
| - **Content-type** – Set to `"application/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 /images/create?fromImage=ubuntu HTTP/1.1 |
| |
| **Example response**: |
| |
| HTTP/1.1 200 OK |
| Content-Type: application/json |

| {"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. |
| |
| 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: |

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

| "username": "jdoe", |
| "password": "secret", |
| "email": "jdoe@acme.com", |
| } |
| ``` |
| |
| - Token based login: |
| |
| ``` |
| { |
| "registrytoken": "9cbaf023786cd7..." |
| } |

| an image ID, similarly only that image (and its parents) are returned and there |
| would be no names referenced in the 'repositories' file for this image ID. |
| |
| 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"} |
| } |
| ``` |
| |

| |
| # 3. Going further |
| |
| ## 3.1 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. |
| |
| ## 3.2 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 |
| from **200 OK** to **101 UPGRADED** and resends the same headers. |
| |
| |
| ## 3.3 CORS Requests |
| |
| To set cross origin requests to the remote api please give values to |
| `--api-cors-header` when running Docker in daemon mode. Set * (asterisk) allows all, |
| default or blank means CORS disabled |
| |
| $ docker daemon -H="192.168.1.9:2375" --api-cors-header="http://foo.bar" |
