This package presents a client for the Docker remote API. It also provides
|
||
|
|
support for the extensions in the [Swarm API](https://docs.docker.com/swarm/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](http://docs.docker.com/engine/reference/api/docker_remote_api/).
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
|
||
|
|
"github.com/fsouza/go-dockerclient"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
endpoint := "unix:///var/run/docker.sock"
|
||
|
|
client, err := docker.NewClient(endpoint)
|
||
|
|
if err != nil {
|
||
|
|
panic(err)
|
||
|
|
}
|
||
|
|
imgs, err := client.ListImages(docker.ListImagesOptions{All: false})
|
||
|
|
if err != nil {
|
||
|
|
panic(err)
|
||
|
|
}
|
||
|
|
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.
|
||
|
|
|
||
|
|
```go
|
||
|
|
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](https://docs.docker.com/machine/), or another
|
||
|
|
application that exports environment variables `DOCKER_HOST`,
|
||
|
|
`DOCKER_TLS_VERIFY`, `DOCKER_CERT_PATH`, you can use NewClientFromEnv.
|
||
|
|
|
||
|
|
|
||
|
|
```go
|
||
|
|
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](Makefile).
|
||
|
|
|
||
|
|
Commited code must pass:
|
||
|
|
|
||
|
|
* [golint](https://github.com/golang/lint) (with some exceptions, see the Makefile).
|
||
|
|
* [go vet](https://golang.org/cmd/vet/)
|
||
|
|
* [gofmt](https://golang.org/cmd/gofmt)
|
||
|
|
* [go test](https://golang.org/cmd/go/#hdr-Test_packages)
|
||
|
|
|
||
|
|
Running `make test` will check all of these. If your editor does not
|
||
|
|
automatically call ``gofmt -s``, `make fmt` will format all go files in this
|
||
|
|
repository.
|
||
|
|
|
||
|
|
## Vendoring
|
||
|
|
|
||
|
|
go-dockerclient uses [dep](https://github.com/golang/dep/) for vendoring. If
|
||
|
|
you're using dep, you should be able to pick go-dockerclient releases and get
|
||
|
|
the proper dependencies.
|
||
|
|
|
||
|
|
With other vendoring tools, users might need to specify go-dockerclient's
|
||
|
|
dependencies manually.
|
||
|
|
|
||
|
|
## Using with Docker 1.9 and Go 1.4
|
||
|
|
|
||
|
|
There's a tag for using go-dockerclient with Docker 1.9 (which requires
|
||
|
|
compiling go-dockerclient with Go 1.4), the tag name is ``docker-1.9/go-1.4``.
|
||
|
|
|
||
|
|
The instructions below can be used to get a version of go-dockerclient that compiles with Go 1.4:
|
||
|
|
|
||
|
|
```
|
||
|
|
% git clone -b docker-1.9/go-1.4 https://github.com/fsouza/go-dockerclient.git $GOPATH/src/github.com/fsouza/go-dockerclient
|
||
|
|
% git clone -b v1.9.1 https://github.com/docker/docker.git $GOPATH/src/github.com/docker/docker
|
||
|
|
% go get github.com/fsouza/go-dockerclient
|
||
|
|
```
