golang app - running it on docker image.

This is a very simple approach to push your app into a docker image. First you need your Dockerfile which does all the hardwork for you, as shown below :-

	# Start from a Debian image with the latest version of Go installed
	# and a workspace (GOPATH) configured at /go.
	FROM golang
	WORKDIR /go/src/app
	COPY . .
	RUN go get -d -v ./...
	RUN go install -v ./...
	# Run the outyet command by default when the container starts.
	CMD ["app"]
	# Document that the service listens on port 8080.
	EXPOSE 8000

If you want to run on kubernetes, the following yaml describe this deployment. Save this into a file called muxApp.yaml and then run kubectl apply -f deployment.yaml.

	apiVersion: apps/v1beta2
	kind: Deployment
	metadata:
	name: muxapp
	spec:
	replicas: 1
	selector:
	matchLabels:
	app: muxapp
	template:
	metadata:
	labels:
	app: muxapp
	spec:
	containers:
	- name: muxapp
	image: kepung/go-app
	ports:
	- containerPort: 443
	- containerPort: 8000
