Kubernetes/Docker - go-microservices

Simple proof of concept Docker container for playing around with local clusters in Kubernetes.

Requirements

• Golang 1.13.8+
• Docker 20.10.7+
• Minikube 1.25.2+

Setup

Install dependencies

go get

Usage

Minikube init.

minikube start --driver=docker

Run the following command before building Docker containers to import said container into Minikube. NOTE: Needs to be re-run for every new terminal.

eval $(minikube docker-env)

Run server locally.

go run main.go

Build Docker container where "my-app" is the name of the project.

docker build -t my-app:latest . 
docker run -dp 8080:8080 --name web my-app:latest

Or use Docker-Compose instead.

docker-compose build
docker-compose up -d
docker-compose ps 
docker-compose down

Deploy a local cluster with x number of replicas defined in kubernetes/deployment.yml and connect to an arbitrary pod.

kubectl apply -f kubernetes/
kubectl get po,svc
minikube ip
add my-app-service port to minikube ip 

Tests

Run unit tests

npm test
