A template project to create a Docker image for a Go application. The example application exposes an HTTP endpoint.
The Docker build uses a multi-stage build setup to minimize the size of the generated Docker image. The Go build uses dep for dependency management.

Docker must be installed. That's it. You do not need to have Go installed.
Step 1: Create the Docker image according to Dockerfile. This step uses Maven to build, test, and package the Go application. The resulting image is 7MB in size.
# This may take a few minutes.
$ docker build -t miguno/golang-docker-build-tutorial:latest .
Step 2: Start a container for the Docker image.
$ docker run -p 8123:8123 miguno/golang-docker-build-tutorial:latest
Step 3: Open another terminal and access the example API endpoint.
$ curl http://localhost:8123/status
{"status": "idle"}
You can run the Go application locally if you have Go installed.
# Build and run the application
$ go run app.go
