This repo contains a go sample web app to demonstrate deployment of go application in k8s environment

• git cli
• kubectl cli
• helm chart
• minikube (for testing)

Docker image for this application is already available on docker registry https://hub.docker.com/r/allloush92/travix_test

You can build the image locally using the following command

git pull https://github.com/Ali-Dalal/sample_web_app.git
docker build -t {TAG} . //replace tag with desired value

by default, helm chart will pull the image directly from docker registry, you can modify web_api/templates/deployment.yml to use a local image if built locally

to install the app, run the following command

helm install web web_api/

the previous command will install k8s templates that include:

• namespace
• deployment
• service

Configuration variables are written in web_api/values.yaml and can be updated on demand (number of replicas, the name of namespace, ..etc)

after installing the helm chart, if you query the number of available pods, kubectl will print the following

kubectl get pods -n travix-dev

if the installation process passes successfully, you can test the service using minikube by running the following cmd

minikube service web-travix-test-service -n travix-dev 

the previous command will produce the following and open the app in the browser
