Pass local docker image in Docker Golang SDK imagePull method - docker

Question

I want to pull a docker image from my local system.
Image name is : example
import (
"github.com/docker/docker/api/types"
"github.com/docker/docker/api/types/container"
"github.com/docker/docker/client"
)
cli, err := client.NewClientWithOpts(client.FromEnv, client.WithAPIVersionNegotiation())
if err != nil {
panic(err)
}
imageName := "example:latest"
out, err := cli.ImagePull(ctx, imageName, types.ImagePullOptions{})
if err != nil {
panic(err)
}
current code is giving me something like this :
panic: Error response from daemon: pull access denied for example, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
Is it possble to pass local docker image to this method, if yes, how ?

Answer 1

First, you can build image locally with tag 'localhost/example:latest'
$ docker build -t "localhost/example:latest" .
Than, you can prepend localhost to image name, so it will try local registry to pull image, so, you can try this:
package main
import (
"fmt"
"github.com/docker/docker/api/types"
"github.com/docker/docker/api/types/container"
"github.com/docker/docker/client"
)
func main(){
cli, err := client.NewClientWithOpts(client.FromEnv, client.WithAPIVersionNegotiation())
if err != nil {
panic(err)
}
imageName := "localhost/example:latest" // <- localhost prepended!
out, err := cli.ImagePull(ctx, imageName, types.ImagePullOptions{})
if err != nil {
panic(err)
}
fmt.Println(out)
}
