http-server

A simple app to create, delete and list users using Mux router.

Tech stack :

• App has been written in Golang
• Used Docker to containerize the app
• Used Docker Compose to demonstrate multi container deployments
• Written K8s components to orchestrate the containers
• Added helm charts for easy deployments of K8 clusters

Installing and running the app locally

  git clone https://github.com/niranjan-n1/http-server.git
  
  cd http-server
  
  go run main.go

Deploying the app as a Docker container

Building the Docker Image locally

  docker build . --tag <imagename>:<tag>  

Pulling the image from docker.io registry

  docker pull niranjann1/httpserver:1.1 

Verify the image

  docker images

Running the image as container

docker run -d -p 8081:8081 --name <container-name> httpserver:1.1

Verify that the container is running

  docker ps

Running mutiple instances of the application using docker-compose

  docker-compose up -d 

Deployment using Helm

Install Helm CLI

  curl -LO https://get.helm.sh/helm-v3.9.0-linux-amd64.tar.gz
  tar -C /tmp/ -zxvf helm-v3.9.0-linux-amd64.tar.gz
  rm helm-v3.9.0-linux-amd64.tar.gz
  mv /tmp/linux-amd64/helm /usr/local/bin/helm
  chmod +x /usr/local/bin/helm

Installing the chart

  helm install <chart-name> <chart>

Eg :
