LOCAL

actuator

Setup a local mysql container:

• Go into docker-compose directory under the root directory of the project
• Use docker-compose -p "sql" up -d
• Access http://localhost:8081/?server=db&username=exchange_rates
• Use local_user/P@ssword1 as user/password credentials

Create local_user user and empty schema local_db by executing the following SQL commands:

CREATE USER IF NOT EXISTS  'local_user'@'%' IDENTIFIED BY 'P@ssword1';
CREATE DATABASE IF NOT EXISTS local_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON local_db.* TO 'local_user'@'%';

export IMAGE_NAME="<image-name>"
export GIT_COMMIT="<git-commit>"

docker build -t $IMAGE_NAME --build-arg GIT_COMMIT=$GIT_COMMIT  --build-arg ENVIRONMENT=local   .

The micro-service can be deployed on a Kubernetes cluster using the DEPLOYMENT pipeline.
