go-dockerclient

Travis GoDoc

This package presents a client for the Docker remote API. It also provides support for the extensions in the Swarm API.

This package also provides support for docker's network API, which is a simple passthrough to the libnetwork remote API. Note that docker's network API is only available in docker 1.8 and above, and only enabled in docker if DOCKER_EXPERIMENTAL is defined during the docker build process.

For more details, check the remote API documentation.

Vendoring

If you are having issues with Go 1.5 and have GO15VENDOREXPERIMENT set with an application that has go-dockerclient vendored, please update your vendoring of go-dockerclient :) We recently moved the vendor directory to external so that go-dockerclient is compatible with this configuration. See 338 and 339 for details.

Example

package main

import (
	"fmt"

	"github.com/fsouza/go-dockerclient"
)

func main() {
	endpoint := "unix:///var/run/docker.sock"
	client, _ := docker.NewClient(endpoint)
	imgs, _ := client.ListImages(docker.ListImagesOptions{All: false})
	for _, img := range imgs {
		fmt.Println("ID: ", img.ID)
		fmt.Println("RepoTags: ", img.RepoTags)
		fmt.Println("Created: ", img.Created)
		fmt.Println("Size: ", img.Size)
		fmt.Println("VirtualSize: ", img.VirtualSize)
		fmt.Println("ParentId: ", img.ParentID)
	}
}

Using with TLS

In order to instantiate the client for a TLS-enabled daemon, you should use NewTLSClient, passing the endpoint and path for key and certificates as parameters.

package main

import (
	"fmt"

	"github.com/fsouza/go-dockerclient"
)

func main() {
	endpoint := "tcp://[ip]:[port]"
	path := os.Getenv("DOCKER_CERT_PATH")
	ca := fmt.Sprintf("%s/ca.pem", path)
	cert := fmt.Sprintf("%s/cert.pem", path)
	key := fmt.Sprintf("%s/key.pem", path)
	client, _ := docker.NewTLSClient(endpoint, cert, key, ca)
	// use client
}

If using docker-machine, or another application that exports environment variables DOCKER_HOST, DOCKER_TLS_VERIFY, DOCKER_CERT_PATH, you can use NewClientFromEnv.

package main

import (
	"fmt"

	"github.com/fsouza/go-dockerclient"
)

func main() {
	client, _ := docker.NewClientFromEnv()
	// use client
}

See the documentation for more details.

Developing

All development commands can be seen in the Makefile.

Commited code must pass:

Running make test will check all of these. If your editor does not automatically call gofmt, make fmt will format all go files in this repository.

	Tag   string
	Force bool
}

TagImageOptions present the set of options to tag an image.

See https://goo.gl/98ZzkU for more details.

type TopResult 

type TopResult struct {
	Titles    []string
	Processes [][]string
}

TopResult represents the list of processes running in a container, as returned by /containers/<id>/top.

type ULimit added in v1.0.5 

type ULimit struct {
	Name string `json:"Name,omitempty" yaml:"Name,omitempty"`
	Soft int64  `json:"Soft,omitempty" yaml:"Soft,omitempty"`
	Hard int64  `json:"Hard,omitempty" yaml:"Hard,omitempty"`
}

ULimit defines system-wide resource limitations This can help a lot in system administration, e.g. when a user starts too many processes and therefore makes the system unresponsive for other users.

type UploadToContainerOptions added in v1.0.7 

type UploadToContainerOptions struct {
	InputStream          io.Reader `json:"-" qs:"-"`
	Path                 string    `qs:"path"`
	NoOverwriteDirNonDir bool      `qs:"noOverwriteDirNonDir"`
}

UploadToContainerOptions is the set of options that can be used when uploading an archive into a container.

See https://goo.gl/Ss97HW for more details.

type Volume added in v1.0.6 

type Volume struct {
	Name       string `json:"Name" yaml:"Name"`
	Driver     string `json:"Driver,omitempty" yaml:"Driver,omitempty"`
	Mountpoint string `json:"Mountpoint,omitempty" yaml:"Mountpoint,omitempty"`
