Please find the architecture diagram at https://drive.google.com/file/d/1qHBmQgGoLnbUws8xLXEn1bedcwGb8UPz/view?usp=sharing

Firstly run the following command,

docker pull akshayrajvanshi1992/pika-pika-ubuntu:latest

Then, after that run the following command:

docker run --name pika-ubuntu -v <folder-path-for-volume>:/data -it akshayrajvanshi1992/pika-pika-ubuntu "/bin/bash"

Dockerized Kafka

Firstly, we add a dockerized version of Kafka and Zookeeper to the project.

Usage

For macOS, we run a simple command.

make

For Windows, we have a simple command here to run from the command prompt or you can just double click the windows-docker-makefile.bat file.

windows-docker-makefile.bat

After the docker has built the container, login into the container with the following command. But first, you will have to know the container ID. You can perform the following commands.

docker ps -a
docker exec -it <Container ID> /bin/bash

After you are inside the docker container bash, perform the following commands:

kafka-topics --zookeeper 127.0.0.1:2181 --create --topic data-retrieval-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic model-execution-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic user-management-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic post-processing-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic session-management-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic api-gateway-service --partitions 1 --replication-factor 1
kafka-topics --zookeeper 127.0.0.1:2181 --create --topic front-end-data-retrieval-service --partitions 1 --replication-factor 1
