In order to run this application you need to have installed:

• minikube > v1.6.2
• kubectl > v1.17.0
• Node > v12.18.2
• Docker > v19.03.5
• python > v3.6
• yarn > v1.22.4
• Gradle > v6.5.1
• Helm > v3.1.1
• mkcert > v1.4.1
• openssl > v2.8.3
• sonar-scanner > v4.5.0

Starting local minikube Kuberentes cluster

In order to run application in development profile, first you need to create minikube cluster:

$ minikube start --cpus=4 --memory=8192

Then you need to mount frontend component files to Kubernetes cluster with command below:

$ minikube mount application/components/frontend:/frontend/src

Then in another terminal window execute:

$ cd scripts && ./start.sh

Example output

123

You can reach a website at URL logged at the end of start script.

Payments

In order to checkout payments in development environment execute command:

$ stripe listen --api-key sk_test_51HdE8mDV6EZPJrHHkftff05Uwa2RNhDQLmnzUbPHuTb4PfYJShQ2OoQHFyPyIWCe3mwL46DM7XECaO68BqDO4GaD001VY2kjNY --load-from-webhooks-api --forward-to https://<MINIKUBE_IP>:32004 --skip-verify

Starting monitoring services

In order to run application in development profile execute:

$ cd scripts && ./run_monitoring_tools.sh

You can reach Grafana and Prometheus at URLs logged at the end of start script.

Starting selenium E2E tests

In order to be able to run E2E tests, first you need to configure your environment with command below:

$ cd scripts/e2e && ./configure_e2e_requirements.sh

Then you can run script with given parameters:

Parameter	Description
--due-to	Sets period of tests execution. [s, m, h, d]
--test-filter	Filter tests to run
--test-exclude	Tests to skip
--stop-on-fail	Stop tests execution after first failed test
--browser	Browser to tests
--seed	Seed used to shuffle tests

To run script run command below with chosen parameters:

$ cd scripts/e2e && ./run_e2e_tests.sh

Analyzing sonarqube output

In order to deploy sonarqube on run command below:

$ cd scripts/sonar && ./start_sonar.sh

It creates two pods with sonarqube and its database - PostreSQL. To analyze the code run command:

$ cd scripts/sonar && ./run_sonnar_scanner.sh

This command analyze application/components directory and sends data to sonarqube available at URL printed on the end of start script.
