## 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`.
|
||
- When the client API version is newer than the daemon's, these calls return an HTTP
|
||
`400 Bad Request` error message.
|
||

||
- **PublishAllPorts** - Allocates a random host port for all of a container's
|
||
exposed ports. Specified as a boolean value.
|
||

||
always restart, `"unless-stopped"` to restart always except when
|
||
user has manually stopped the container or `"on-failure"` to restart only when the container
|
||
exit code is non-zero. If `on-failure` is used, `MaximumRetryCount`
|
||
controls the number of times to retry before giving up.
|
||
The default is not to restart. (optional)
|
||
An ever increasing delay (double the previous delay, starting at 100mS)
|
||
is added before each restart to prevent flooding the server.
|
||
- **NetworkMode** - Sets the networking mode for the container. Supported
|
||

|
||
`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.
|
||
|
||
**Query parameters**:
|
||
|
||

|
||
|
||
**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.

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
|
||
{
|

"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.

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 /v1.21/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)
|
||
|
||
**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`
|
||
|
||

|
||
|
||
**Example request**:
|
||
|
||
POST /v1.21/images/create?fromImage=busybox&tag=latest HTTP/1.1
|
||

|
||
{"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.
|
||
- **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.
|
||
|
||

|
||
(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.
|
||
|
||
**Example request**
|
||

||
`ubuntu:latest`), then only that image (and its parents) are returned; if it is
|
||
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.

#### 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"}
|
||
}
|
||
```
|
||
|
||
#### Exec Create

|
||
the exec process inside the container. Format is one of: `"user"`,
|
||
`"user:group"`, `"uid"`, or `"uid:gid"`.
|
||
|
||
**Status codes**:
|
||
|
||
- **201** – no error

#### Exec Start
|
||
|
||
`POST /exec/(id)/start`

**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 across a cluster of docker hosts.
|
||
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
|
||
- **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** - Network specific options to be used by the drivers

## 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 Engine API please give values to
|
||
`--api-cors-header` when running Docker in daemon mode. Set * (asterisk) allows all,
|
||
default or blank means CORS disabled
|
||
|
||
$ dockerd -H="192.168.1.9:2375" --api-cors-header="http://foo.bar"
|
