A react app which displays the current value of bitcoin updated every 10 seconds and the average value for the last 10 minutes.
- React
- JavaScript
- Nginx
- Docker
- Helm
- Github Actions
To run the app locally first install the dependencies:
npm install
Then run:
npm start
This will open the web app on a new browser on localhost:3000
The application is built and deployed to the cluster using the CI/CD pipeline located under .github\workflows.
The pipeline has 3 stages and performs the following:
- build: Build the docker image and push it to Azure Container Registry.
- publish: Build the helm chart and publish it to Azure Container Registry.
- deploy: Install the helm chart to the cluster.
The pipeline reuses a template located in the workflow-templates repo. The actual code of the pipeline is located in the template.
As a prerequisite the pipeline needs the following secrets in github actions:
- ACR_REGISTRY: Name of the Azure Container Registry.
- ACR_USERNAME: Username for a Service Principal which has access to ACR.
- ACR_PASSWORD: Password of the Service Principal.
- AZURE_CREDENTIALS: Credentials for SP which has access to Azure Key Vault. (this is for fetching the kubeconfig)
- KEY_VAULT: Name of the Key Vault.
To run the pipeline just push a change to the main branch (whether directly or via a pull request). Or you can re-run an existing pipeline in the repo.
