The goal of this tutorial is to add the environment variables and publish the function version. We will also add secured variables, and to encrypt these variables we are going to use the AWS KMS key. We will have a project property added in the deploy workflow and this project property value will contain the list of the environment variables that we are going to use in the workflow input. We can use the dynamic value in both the environment file and input argument, please refer to this document to get more details about environment variables' acceptable structure: AWS Lambda Environment Variables Accepted Structure.
