Classic Cipher Generation

Backgournd

As part of learning kubernetes, publish a Web Service that uses kubernetes to deepen my understanding of kubernetes.
About motivation of a Web Service, I knew the classic ciphers as we encountered in "The Code Book", and I came to be interesting in the coding of the cipher's algorithm, I built a simple encrypt / decript service.

Command List - Docker Compose

Run Applications by using Docker Compose

• Start / stop the applications

docker-compose up -d --build
docker-compose down

• Enter the container

docker exec -it classic_cipher_generation_web bash
docker exec -it classic_cipher_generation_app bash
docker exec -it classic_cipher_generation_db bash
mysql -u user -ppassword classic_cipher_generation_db
docker exec -it classic_cipher_generation_redis bash
redis-cli

• Check the container log

docker logs classic_cipher_generation_app
docker logs classic_cipher_generation_db
