The most straightforward way to use this image is to use a Go container as both the build and runtime environment. In your `Dockerfile`, writing something along the lines of the following will compile and run your project:

```dockerfile
FROM golang:1.13
FROM golang:1.14

WORKDIR /go/src/app
COPY . .

There may be occasions where it is not appropriate to run your app inside a container. To compile, but not run your app inside the Docker instance, you can write something like:

```console
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.13 go build -v
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.14 go build -v
```

This will add your current directory as a volume to the container, set the working directory to the volume, and run the command `go build` which will tell go to compile the project in the working directory and output the executable to `myapp`. Alternatively, if you have a `Makefile`, you can run the `make` command inside your container.

```console
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.13 make
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.14 make
```

## Cross-compile your app inside the Docker container

If you need to compile your application for a platform other than `linux/amd64` (such as `windows/386`):

```console
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -e GOOS=windows -e GOARCH=386 golang:1.13 go build -v
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -e GOOS=windows -e GOARCH=386 golang:1.14 go build -v
```

Alternatively, you can build for multiple platforms at once:

```console
$ docker run --rm -it -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.13 bash
$ docker run --rm -it -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.14 bash

> for GOARCH in 386 amd64; do
> export GOOS GOARCH
