description: |

The Engine API is an HTTP API served by Docker Engine. It is the API the

Docker client uses to communicate with the Engine, so everything the Docker

client can do can be done with the API.

Most of the client's commands map directly to API endpoints (e.g. `docker ps`

is `GET /containers/json`). The notable exception is running containers,

which consists of several API calls.

# Errors

The 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"

}

```

# Versioning

The API is usually changed in each release, so API calls are versioned to

ensure that clients don't break. To lock to a specific version of the API,

you prefix the URL with its version, for example, call `/v1.30/info` to use

the v1.30 version of the `/info` endpoint. If the API version specified in

the URL is not supported by the daemon, a HTTP `400 Bad Request` error message

is returned.

If you omit the version-prefix, the current version of the API (v1.42) is used.

For example, calling `/info` is the same as calling `/v1.42/info`. Using the

API without a version-prefix is deprecated and will be removed in a future release.

Engine releases in the near future should support this version of the API,

so your client will continue to work even if it is talking to a newer Engine.

The API uses an open schema model, which means server may add extra properties

to responses. Likewise, the server will ignore any extra query parameters and

request body properties. When you write clients, you need to ignore additional

properties in responses to ensure they do not break when talking to newer

daemons.

# Authentication

Authentication for registries is handled client side. The client has to send

authentication details to various endpoints that need to communicate with

registries, such as `POST /images/(name)/push`. These are sent as

`X-Registry-Auth` header as a [base64url encoded](https://tools.ietf.org/html/rfc4648#section-5)

(JSON) string with the following structure:

```

{

"username": "string",

"password": "string",

"email": "string",

"serveraddress": "string"

}

```

The `serveraddress` is a domain/IP without a protocol. Throughout this

structure, double quotes are required.

If you have already got an identity token from the [`/auth` endpoint](#operation/SystemAuth),

you can just pass this instead of credentials:

```

{

"identitytoken": "9cbaf023786cd7..."

}

```

# The tags on paths define the menu sections in the ReDoc documentation, so

# the usage of tags must make sense for that:

# - They should be singular, not plural.

# - There should not be too many tags, or the menu becomes unwieldy. For

# example, it is preferable to add a path to the "System" tag instead of

# creating a tag with a single path in it.

# - The order of tags in this list defines the order in the menu.

Binds:

type: "array"

description: |

A list of volume bindings for this container. Each volume binding

is a string in one of these forms:

- `host-src:container-dest[:options]` to bind-mount a host path

into the container. Both `host-src`, and `container-dest` must

be an _absolute_ path.

- `volume-name:container-dest[:options]` to bind-mount a volume

managed by a volume driver into the container. `container-dest`

must be an _absolute_ path.

`options` is an optional, comma-delimited list of:

- `nocopy` disables automatic copying of data from the container

path to the volume. The `nocopy` flag only applies to named volumes.

- `[ro|rw]` mounts a volume read-only or read-write, respectively.

If omitted or set to `rw`, volumes are mounted read-write.

- `[z|Z]` applies SELinux labels to allow or deny multiple containers

to read and write to the same volume.

- `z`: a _shared_ content label is applied to the content. This

label indicates that multiple containers can share the volume

content, for both reading and writing.

- `Z`: a _private unshared_ label is applied to the content.

This label indicates that only the current container can use

a private volume. Labeling systems such as SELinux require

proper labels to be placed on volume content that is mounted

into a container. Without a label, the security system can

prevent a container's processes from using the content. By

default, the labels set by the host operating system are not

modified.

- `[[r]shared|[r]slave|[r]private]` specifies mount

[propagation behavior](https://www.kernel.org/doc/Documentation/filesystems/sharedsubtree.txt).

This only applies to bind-mounted volumes, not internal volumes

or named volumes. Mount propagation requires the source mount

point (the location where the source directory is mounted in the

host operating system) to have the correct propagation properties.

For shared volumes, the source mount point must be set to `shared`.

For slave volumes, the mount must be set to either `shared` or

`slave`.
