Go client for the Docker Engine API

The docker command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does – running containers, pulling images, managing swarms, etc.

For example, to list all containers (the equivalent of docker ps --all):

package main

import (
	"context"
	"fmt"

	"github.com/docker/docker/api/types/container"
	"github.com/docker/docker/client"
)

func main() {
	apiClient, err := client.NewClientWithOpts(client.FromEnv)
	if err != nil {
		panic(err)
	}
	defer apiClient.Close()

	containers, err := apiClient.ContainerList(context.Background(), container.ListOptions{All: true})
	if err != nil {
		panic(err)
	}

	for _, ctr := range containers {
		fmt.Printf("%s %s (status: %s)\n", ctr.ID, ctr.Image, ctr.Status)
	}
}

Full documentation is available on pkg.go.dev.

Documentation

Overview

Package client is a Go client for the Docker Engine API.

For more information about the Engine API, see the documentation: https://docs.docker.com/engine/api/

Usage

You use the library by constructing a client object using NewClientWithOpts and calling methods on it. The client can be configured from environment variables by passing the FromEnv option, or configured manually by passing any of the other available [Opts].

For example, to list running containers (the equivalent of "docker ps"):

package main

import (
	"context"
	"fmt"

	"github.com/docker/docker/api/types/container"
	"github.com/docker/docker/client"
)

func main() {
	cli, err := client.NewClientWithOpts(client.FromEnv)
	if err != nil {
		panic(err)
	}

	containers, err := cli.ContainerList(context.Background(), container.ListOptions{})
	if err != nil {
		panic(err)
	}

	for _, ctr := range containers {
		fmt.Printf("%s %s\n", ctr.ID, ctr.Image)
	}
}

const DefaultDockerHost = "unix:///var/run/docker.sock"

DefaultDockerHost defines OS-specific default host if the DOCKER_HOST (EnvOverrideHost) environment variable is unset or empty.

View Source
const DummyHost = "api.moby.localhost"

DummyHost is a hostname used for local communication.

It acts as a valid formatted hostname for local connections (such as "unix://" or "npipe://") which do not require a hostname. It should never be resolved, but uses the special-purpose ".localhost" TLD (as defined in RFC 2606, Section 2 and RFC 6761, Section 6.3).

RFC 7230, Section 5.4 defines that an empty header must be used for such cases:

If the authority component is missing or undefined for the target URI,
then a client MUST send a Host header field with an empty field-value.

However, Go stdlib enforces the semantics of HTTP(S) over TCP, does not allow an empty header to be used, and requires req.URL.Scheme to be either "http" or "https".

For further details, refer to:

Variables

View Source
var ErrRedirect = errors.New("unexpected redirect in response")

ErrRedirect is the error returned by checkRedirect when the request is non-GET.

Functions

func CheckRedirect

func CheckRedirect(_ *http.Request, via []*http.Request) error

CheckRedirect specifies the policy for dealing with redirect responses. It can be set on http.Client.CheckRedirect to prevent HTTP redirects for non-GET requests. It returns an ErrRedirect for non-GET request, otherwise returns a http.ErrUseLastResponse, which is special-cased by http.Client to use the last response.

Go 1.8 changed behavior for HTTP redirects (specifically 301, 307, and 308) in the client. The client (and by extension API client) can be made to send a request like "POST /containers//start" where what would normally be in the name section of the URL is empty. This triggers an HTTP 301 from the daemon.

In go 1.8 this 301 is converted to a GET request, and ends up getting a 404 from the daemon. This behavior change manifests in the client in that before, the 301 was not followed and the client did not generate an error, but now results in a message like "Error response from daemon: page not found".

func ErrorConnectionFailed

func ErrorConnectionFailed(host string) error

ErrorConnectionFailed returns an error with host in the error message when connection to docker daemon failed.

func FromEnv

func FromEnv(c *Client) error

FromEnv configures the client with values from environment variables. It is the equivalent of using the WithTLSClientConfigFromEnv, WithHostFromEnv, and WithVersionFromEnv options.

FromEnv uses the following environment variables:

  • DOCKER_HOST (EnvOverrideHost) to set the URL to the docker server.
  • DOCKER_API_VERSION (EnvOverrideAPIVersion) to set the version of the API to use, leave empty for latest.
  • DOCKER_CERT_PATH (EnvOverrideCertPath) to specify the directory from which to load the TLS certificates ("ca.pem", "cert.pem", "key.pem').
  • DOCKER_TLS_VERIFY (EnvTLSVerify) to enable or disable TLS verification (off by default).

func IsErrConnectionFailed

func IsErrConnectionFailed(err error) bool

IsErrConnectionFailed returns true if the error is caused by connection failed.

func IsErrNotFound

func IsErrNotFound(err error) bool

IsErrNotFound returns true if the error is a NotFound error, which is returned by the API when some object is not found. It is an alias for errdefs.IsNotFound.

func ParseHostURL

func ParseHostURL(host string) (*url.URL, error)

ParseHostURL parses a url string, validates the string is a host url, and returns the parsed URL

Types

type APIClient

type APIClient interface {
	CommonAPIClient
	// contains filtered or unexported methods
}

APIClient is an interface that clients that talk with a docker server must implement.

type CheckpointAPIClient

type CheckpointAPIClient interface {
	CheckpointCreate(ctx context.Context, container string, options checkpoint.CreateOptions) error
	CheckpointDelete(ctx context.Context, container string, options checkpoint.DeleteOptions) error
	CheckpointList(ctx context.Context, container string, options checkpoint.ListOptions) ([]checkpoint.Summary, error)
}

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client is the API client that performs all operations against a docker server.

func NewClient deprecated

func NewClient(host string, version string, client *http.Client, httpHeaders map[string]string) (*Client, error)

NewClient initializes a new API client for the given host and API version. It uses the given http client as transport. It also initializes the custom http headers to add to each request.

It won't send any version information if the version number is empty. It is highly recommended that you set a version or your client may break if the server is upgraded.

Deprecated: use NewClientWithOpts passing the WithHost, WithVersion, WithHTTPClient and WithHTTPHeaders options. We recommend enabling API version negotiation by passing the WithAPIVersionNegotiation option instead of WithVersion.

func NewClientWithOpts

func NewClientWithOpts(ops ...Opt) (*Client, error)

NewClientWithOpts initializes a new API client with a default HTTPClient, and default API host and version. It also initializes the custom HTTP headers to add to each request.

It takes an optional list of Opt functional arguments, which are applied in the order they're provided, which allows modifying the defaults when creating the client. For example, the following initializes a client that configures itself with values from environment variables (FromEnv), and has automatic API version negotiation enabled (WithAPIVersionNegotiation).

cli, err := client.NewClientWithOpts(
	client.FromEnv,
	client.WithAPIVersionNegotiation(),
)

func NewEnvClient deprecated

The stream format on the response will be in one of two formats:

If the container is using a TTY, there is only a single stream (stdout), and data is copied directly from the container output stream, no extra multiplexing or headers.

If the container is *not* using a TTY, streams for stdout and stderr are multiplexed. The format of the multiplexed stream is as follows:

ContainerWait waits until the specified container is in a certain state indicated by the given condition, either "not-running" (default), "next-exit", or "removed".

If this client's API version is before 1.30, condition is ignored and ContainerWait will return immediately with the two channels, as the server will wait as if the condition were "not-running".

If this client's API version is at least 1.30, ContainerWait blocks until the request has been acknowledged by the server (with a response header), then returns two channels on which the caller can wait for the exit status of the container or an error if there was a problem either beginning the wait request or in getting the response. This allows the caller to synchronize ContainerWait with other calls, such as specifying a "next-exit" condition before issuing a ContainerStart request.

Example (WithTimeout)
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

client, _ := NewClientWithOpts(FromEnv)
_, errC := client.ContainerWait(ctx, "container_id", "")
if err := <-errC; err != nil {

func (*Client) NegotiateAPIVersion

func (cli *Client) NegotiateAPIVersion(ctx context.Context)

NegotiateAPIVersion downgrades the client's API version to match the APIVersion if the ping version is lower than the default version. If the API version reported by the server is higher than the maximum version supported by the client, it uses the client's maximum version.

If a manual override is in place, either through the "DOCKER_API_VERSION" (EnvOverrideAPIVersion) environment variable, or if the client is initialized with a fixed version (WithVersion), no negotiation is performed.

If the API server's ping response does not contain an API version, or if the client did not get a successful ping response, it assumes it is connected with an old daemon that does not support API version negotiation, in which case it downgrades to the latest version of the API before version negotiation was added (1.24).

func (*Client) NegotiateAPIVersionPing
