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
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:
FROM winamd64/golang:1.8 WORKDIR /go/src/app COPY . . RUN go-wrapper download # "go get -d -v ./..." RUN go-wrapper install # "go install -v ./..." CMD ["go-wrapper", "run"] # ["app"]
You can then build and run the Docker image:
$ docker build -t my-golang-app . $ docker run -it --rm --name my-running-app my-golang-app
go-wrapper run includes
set -x so the binary name is printed to stderr on application startup. If this behavior is undesirable, then switching to
CMD ["app"] (or
CMD ["myapp"] if a Go custom import path is in use) will silence it by running the built binary directly.
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:
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp winamd64/golang:1.8 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.
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp winamd64/golang:1.8 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
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -e GOOS=windows -e GOARCH=386 winamd64/golang:1.8 go build -v
Alternatively, you can build for multiple platforms at once:
$ docker run --rm -it -v "$PWD":/usr/src/myapp -w /usr/src/myapp winamd64/golang:1.8 bash $ for GOOS in darwin linux; do > for GOARCH in 386 amd64; do > go build -v -o myapp-$GOOS-$GOARCH > done > done
winamd64/golang images come in many flavors, each designed for a specific use case.
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.
This image is based on Windows Server Core (
microsoft/windowsservercore). As such, it only works in places which that image does, such as Windows 10 Professional/Enterprise (Anniversary Edition) or Windows Server 2016.
