How to use docker-api with go modules

You’re trying to use client.NewClientWithOpts from github.com/docker/docker/client module and you can’t find it? Getting client.NewClientWithOpts not declared by package client?

I’ve been there, and fix is relatively easy:

First add this line to your go.mod file:
```
// force go mod to pull proper package for docker
replace github.com/docker/docker => github.com/docker/engine v0.0.0-20191113042239-ea84732a7725
```
This tells go modules to replace references to docker/docker with docker/engine - where the module is really stored.
Make sure that your go.mod file references proper packages. In my case it was replacing gopkg.in references with the ones to github:
```
 github.com/docker/docker v1.13.1
 github.com/docker/engine-api v0.4.0
```

Voilà - go resolves proper docker api client package now.
