Quick reference

Go | openEuler

Current Go(Golang) docker images are built on the openEuler. This repository is free to use and exempted from per-user rate limits.

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

The tag of each Go docker image is consist of the version of Go and the version of basic image. The details are as follows

Tags Currently Architectures
1.17.3-oe2203lts go 1.17.3 on openEuler 22.03-LTS amd64, arm64
1.22.5-oe2203sp4 go 1.22.5 on openEuler 22.03-LTS-SP4 amd64, arm64

Usage

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):

    复制代码
    # Dockerfile
    FROM openeuler/go:{Tag}
    
    WORKDIR /usr/src/app
    COPY go.mod go.sum ./
    RUN go mod download && go mod verify
    COPY . .
    RUN go build -v -o /usr/local/bin/app ./...
    CMD ["app"]

    You can then build and run the Docker image:

    复制代码
    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:

    复制代码
    docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.22 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.

    复制代码
    docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.22 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):

    复制代码
    docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -e GOOS=windows -e GOARCH=386 golang:1.22 go build -v

    Alternatively, you can build for multiple platforms at once:

    bash 复制代码
    $ docker run --rm -it -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.22 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
  • View container running logs

    bash 复制代码
    docker logs -f my-go
  • To get an interactive shell

    bash 复制代码
    docker exec -it my-go /bin/bash
