client: define a "dummy" hostname to use for local connections
For local communications (npipe://, unix://), the hostname is not used,
but we need valid and meaningful hostname.

The current code used the client's `addr` as hostname in some cases, which
could contain the path for the unix-socket (`/var/run/docker.sock`), which
gets rejected by go1.20.6 and go1.19.11 because of a security fix for
[CVE-2023-29406 ][1], which was implemented in  https://go.dev/issue/60374.

Prior versions go Go would clean the host header, and strip slashes in the
process, but go1.20.6 and go1.19.11 no longer do, and reject the host
header.

This patch introduces a `DummyHost` const, and uses this dummy host for
cases where we don't need an actual hostname.

Before this patch (using go1.20.6):

    make GO_VERSION=1.20.6 TEST_FILTER=TestAttach test-integration
    === RUN   TestAttachWithTTY
        attach_test.go:46: assertion failed: error is not nil: http: invalid Host header
    --- FAIL: TestAttachWithTTY (0.11s)
    === RUN   TestAttachWithoutTTy
        attach_test.go:46: assertion failed: error is not nil: http: invalid Host header
    --- FAIL: TestAttachWithoutTTy (0.02s)
    FAIL

With this patch applied:

    make GO_VERSION=1.20.6 TEST_FILTER=TestAttach test-integration
    INFO: Testing against a local daemon
    === RUN   TestAttachWithTTY
    --- PASS: TestAttachWithTTY (0.12s)
    === RUN   TestAttachWithoutTTy
    --- PASS: TestAttachWithoutTTy (0.02s)
    PASS

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 running containers (the equivalent of docker ps):

package main

import (
	"context"
	"fmt"

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

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

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

	for _, container := range containers {
		fmt.Printf("%s %s\n", container.ID[:10], container.Image)
	}
}

Full documentation is available on GoDoc.
