# What is Go?

Go (a.k.a., Golang) is a programming language first developed at Google. It is a statically-typed language with syntax loosely derived from C, but with additional features such as garbage collection, type safety, some dynamic-typing capabilities, additional built-in types (e.g., variable-length arrays and key-value maps), and a large standard library.

# How to use this image

**Note:** `/go` is world-writable to allow flexibility in the user which runs the container (for example, in a container started with `--user 1000:1000`, running `go get github.com/example/...` into the default `$GOPATH` will succeed). While the `777` directory would be insecure on a regular host setup, there are not typically other processes or users inside the container, so this is equivalent to `700` for Docker usage, but allowing for `--user` flexibility.

## Start a Go instance in your app

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 (assuming it uses `go.mod` for dependency management):

```dockerfile
FROM arm32v6/golang:1.26

WORKDIR /usr/src/app

# pre-copy/cache go.mod for pre-downloading dependencies and only redownloading them in subsequent builds if they change
COPY go.mod go.sum ./
RUN go mod download

COPY . .
RUN go build -v -o /usr/local/bin/app ./...

CMD ["app"]
```

You can then build and run the Docker image:

```console
$ docker build -t my-golang-app .
$ docker run -it --rm --name my-running-app my-golang-app
```

## Compile your app inside the Docker container

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 arm32v6/golang:1.26 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 arm32v6/golang:1.26 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 arm32v6/golang:1.26 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 arm32v6/golang:1.26 bash
$ for GOOS in darwin linux; do
>   for GOARCH in 386 amd64; do
>     export GOOS GOARCH
>     go build -v -o myapp-$GOOS-$GOARCH
>   done
> done
```

## Git LFS

If downloading your dependencies results in an error like "checksum mismatch", you should check whether they are using [Git LFS](https://git-lfs.com/) (and thus need it installed for downloading them and calculating correct `go.sum` values).

# Image Variants

The `arm32v6/golang` images come in many flavors, each designed for a specific use case.

## `arm32v6/golang:<version>`

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

## `arm32v6/golang:<version>-alpine`

This image is based on the popular [Alpine Linux project](https://alpinelinux.org), available in [the `alpine` official image](https://hub.docker.com/_/alpine). Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly experimental, and *not* officially supported by the Go project (see [golang/go#19938](https://github.com/golang/go/issues/19938) for details).

The main caveat to note is that it does use [musl libc](https://musl.libc.org) instead of [glibc and friends](https://www.etalabs.net/compare_libcs.html), which can lead to unexpected behavior. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, additional related tools (such as `git`, `gcc`, or `bash`) are not included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the [`alpine` image description](https://hub.docker.com/_/alpine/) for examples of how to install packages if you are unfamiliar). See also [docker-library/golang#250 (comment)](https://github.com/docker-library/golang/issues/250#issuecomment-451201761) for a longer explanation.

## `arm32v6/golang:<version>-tip`

The term "tip" in the Go community is used to refer to the latest development branch ([a leftover convention from previously using `hg` for version control](https://github.com/golang/build/blob/6383021611af0e07cbf0a60222e066662557c796/cmd/coordinator/internal/legacydash/build.go#L313-L314)).

These tags contains builds of Go's latest development branch, and they are updated on a ~weekly cadence.
