Helm Chart to deploy DaytraderMicroservice

This repo contains a Helm chart that can be used to deploy Daytrader Microservices onto a supported Kubernetes cluster.

Using the Chart

Installation

When kubernetes cluster is ready,

  • Clone the deploy-daytrader app in your root node i.e. node-0. You can use the command git clone https://github.com/ssmtariq/deploy-daytrader.git
  • Open terminal in node-0 and change directory to deploy-daytrader app by cd deploy-daytrader
  • [Optional] To change the docker image tag to be deployed
    • Open helm/Chart.yaml file and update the field appVersion. For instance, default appVersion: 4.0.18 to appVersion: optimized.
  • Check the .env file and set
    • APP_VERSION which represents the tag in docker-hub for DayTrader microservice images
    • REPOSITORY_ROOT which represents the repository name in docker-hub for DayTrader microservice images
  • Open the helm/values.yamlfile
    • Update the cluster->dns property with dns value (not IP address) of the root node node-0 of your kubernetes cluster. Make sure you typed them in lower-case
    • Update the image->namespace with docker-hub repo name (if-required)
  • Now, to install DayTrader microservices run sh scripts/install-daytrader.sh.

Running

Once installed, run sh scripts/port-forward.sh to forward the daytrader application to http://localhost:5443.

Keep the scripts/port-forward.sh script running in a terminal and then the daytrader app will be available at your machine at http://localhost:5443/

Try curl https://localhost:5443/ before checking from the web browser If you run the commands from vscode terminal, also check if the PORT is being forwarded correctly VSCode PORTS
