This repo shows a simple walk through how to build and deploy service with http interface to kubernetes. Starting with the hello world example in the first commit and ending up with small REST API with benchmarks and test cases with data race detection.

• Minikube running
• Docker client configured to use minikube
• Go and make installed

Edit your code and run

make docker-build

This will run docker build command and bump version if build was successful. If you check the Dockerfile you can se that we are using multi-stage build.

In first stage we use golang:1.10 to test and build the binary and then copy that to actual image which is build from scratch.

Run

make kube-deploy

This command will call kubectl apply with our deployment.yaml file and replace the version in deployment.yaml to match one in VERSION

After the first deployment it is required to expose our app by running

make kube-expose

Now the app should be accessible and minikube should give the url for it

minikube service demo-app --url

To run all tests locally with race detection and code coverage run

make benchmark

To run all bencmarks run

make test
