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 @@ -134,13 +134,13 @@ $ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.13 make If you need to compile your application for a platform other than `linux/amd64` (such as `windows/386`): ```console -$ 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 GOOS in darwin linux; do > for GOARCH in 386 amd64; do > export GOOS GOARCH
