Sales Leads API freelance project with CDK, on top of API Gateway with Lambda Functions and RDS-MySQL. [OLD FREELANCE PROJECT]

SOLAR-COMMUNITIES-API (FREELANCE PROJECT 2020)

Infrastructure as Code and Source Development for the solar-API that queries and process lead information.

Architecture

AWS architecture and Cloudformation Stacks segmentation for the deployment.

Stack Deployment Dependencies

This diagram illustrates how the CloudFormation stacks and Outputs/Inputs are related for deployments.

Deployment Commands

To deploy the CDK solutions, you must follow the steps on the important_commands.sh and deploy the needed stack.

./important_commands.sh

Keep in mind that to control the deployment ENVIRONMENT, by default is dev, but to change to prod, configure the environment variable as follows:

export ENVIRONMENT="prod"

CDK Deployment example

This would be an example of a development deployment for the Storage-RDS Stack:

# Go to the "cdk-solar-api" directory:
cd cdk-solar-api || echo "Make sure that the folder exists"

# Activate virtual environment for Python dependencies:
# --> Remark: if not installed, create it first and install dependencies.
source .venv/bin/activate || echo "Make sure that virtual env exists"

# Select environment for the deployment:
export ENVIRONMENT="dev"

# To see changes before deployment (changeset):
cdk synthesize --app "python3 app_storage_rds.py"

# Deploy the stack for RDS storage solution
cdk deploy --app "python3 app_storage_rds.py"

CDK Deletion example (Danger Zone)

This would be an example of how to delete the Storage-RDS Stack:

# Go to the "cdk-solar-api" directory:
cd cdk-solar-api || echo "Make sure that the folder exists"

# Activate virtual environment for Python dependencies:
# --> Remark: if not installed, create it first and install dependencies.
source .venv/bin/activate || echo "Make sure that virtual env exists"

# Select environment for the deployment:
export ENVIRONMENT="dev"

# Destroy the stack if it needs to be deleted
# (WARNING): this command will delete all resources!!!
cdk destroy --app "python3 app_storage_rds.py"

Extra Notes and Remarks

• If you want to delete a deployment and don't have available the CDK, you can go to the AWS Console and search for the CloudFormation service. Then enter the Stacks and search the desired stack to be delete. Then click on Delete option and follow the deletion steps.
• To delete one the storage stacks (in case that the solution ever requires to do so), previous stack dependencies must be delete as illustrated in the Stack Deployment Dependencies
