CricRadio (Containerizing using Docker)

Listen to the Commentary of Live Cricket Matches.

Components of the Project

✨ MySQL Database

✨ Kafka

• Introduction to Kafka - https://www.youtube.com/watch?v=heR3I3Wxgro
• Running Kafka on Docker with Compose - https://www.youtube.com/watch?v=ncTosfaZ5cQ

✨ Kafka's REST API

✨ Go Microservice (Heart of the Project)

• Get Live Matches from ESPNCricInfo API and update to mySQL database.
• Scrape the Web page of each match to get ball-to-ball commentary.
• Create a unique topic in Kafka for each match and update ball-to-ball commentary to Kafka.

✨ Web Microservice (Face of the Project)

• Developed Using React.
• Display List of Live Matches.
• Pull the text Commentary from Kafka and convert it into speech.
• Play the commentary of the Selected Match.

Run the project on your local machine

✨ Install Docker & Docker Compose

✨ Clone the Code into your machine.

✨ Start the Docker Daemon

✨ change the directory to "CricRadio" & Run the following command

docker-compose up

✨ Go to localhost:3000 to listen to the commentary. It's that simple. If you have any problem, create an issue here.

Building or Pulling Docker Images for each MicroService to run as a Container

✨ GO MicroService

• Write the Dockerfile
• Run the following command to build the Docker Image inside "cricradio-go-svc" directory

docker build -t suhasgumma/cricradio-go-svc:latest . 

• Create a Repository in Dockerhub & Push the Image.

docker push suhasgumma/cricradio-go-svc:latest   

• Command to pull the image from Dockerhub

docker pull suhasgumma/cricradio-go-svc

✨ Web MicroService

• Write the Dockerfile
• Run the following commands to build the Docker Image inside "cricradio-web-svc" directory

docker build -t suhasgumma/cricradio-web-svc:latest . 

• Create a Repository in Dockerhub & Push the Image.

docker push suhasgumma/cricradio-web-svc:latest   

• Command to pull the image from Dockerhub

docker pull suhasgumma/cricradio-web-svc

• Change the base image of node to "alpine" version to reduce the image size.

docker build -t suhasgumma/cricradio-web-svc:alpine . 
docker push suhasgumma/cricradio-web-svc:alpine  

✨ MySQL

• Use the official Docker Image - https://hub.docker.com/_/mysql
• Set the root password by using environment variable "MYSQL_ROOT_PASSWORD"

✨ Kafka

• Use the Confluent Community Docker Image for Apache Kafka.
• More Info here - https://hub.docker.com/r/confluentinc/cp-kafka/

Using Volumes to Persist Data

• If the Container stops running for any reason, the data will be lost if not stored in volumes.
• In Our project, SQL databases and Kafka topics are vulnerable to data loss.
• To counter that, we use named volumes to persist data on the local machine.

Writing docker-compose.yml

• List all the containers as services.
• Set the required environment variables for each service.
• Map the ports required.
• Define volumes required for the service if needed.
• List all the volumes needed in the volumes section.
