# AWS Lambda & Terraform Commands Description

# 1. Invoke the Lambda function locally and save output to out.json

# 2. Build a shaded JAR (fat JAR) with all dependencies

# 3. Build a ZIP package (for Lambda deployment)
mvn clean package -Passembly-zip

# 4. Stream and follow Lambda logs in real-time
awslocal logs tail /aws/lambda/SpringBootLambdaFunction --follow

# 5. Initialize Terraform for LocalStack environment
tflocal init

# 6. Preview Terraform deployment changes
tflocal plan -var-file="terraform.tfvars"
terraform plan -var-file="terraform.tfvars"

# 7. Deploy all Terraform resources automatically
tflocal apply -var-file="terraform.tfvars" -auto-approve
