Kosli Reporter

Terraform module to deploy the Kosli environment reporter as an AWS lambda function. At the moment, the module only supports reporting of ECS, Lambda and S3 environment types.

In order to deploy the Kosli reporter module, you will need to do the following:

1. Set up Kosli API token:

• Login to Kosli and generate a new service account and API key
• Store the Kosli API key value in an AWS SSM parameter (SecureString type). By default, Lambda Reporter will search for the kosli_api_token SSM parameter, but it is also possible to set custom parameter name (use kosli_api_token_ssm_parameter_name variable).

2. Install Terraform: If you haven't already, you'll need to install Terraform on your local machine. You can download Terraform from the official website.

3. Configure your AWS credentials: Terraform needs access to your AWS account to be able to manage your resources. You can set up your AWS credentials by following the instructions in the AWS documentation

4. Create a Terraform configuration: In order to use the Kosli reporter module, you'll need to create a Terraform configuration. Here are configuration examples that will track ECS, Lambda, S3 resources.

5. Initialize and run Terraform: Once Terraform configuration is created, you'll need to initialize Terraform by running the terraform init command in the same directory as your configuration files. This will download the necessary modules and providers for your configuration. Then, you can run the terraform apply command to apply your configuration.

6. To check Lambda reporter logs you can go to the AWS console -> Lambda service -> choose your lambda reporter function -> Monitor tab -> Logs tab.

Set custom IAM role

It is possible to provide custom IAM role. In this case you need to disable default role creation by setting the parameter create_role to false and providing custom role ARN with parameter role_arn:

module "lambda_reporter" {
  source  = "kosli-dev/kosli-reporter/aws"
  version = "0.5.0"

  name                       = "staging_app"
  kosli_environment_type     = "s3"
  kosli_cli_version          = "v2.7.8"
  kosli_environment_name     = "staging"
  kosli_org                  = "my-organisation"
  # kosli_host                 = "https://app.kosli.com" # defaulted to app.kosli.com
  reported_aws_resource_name = "my-s3-bucket"
  role_arn                   = aws_iam_role.this.arn
  create_role                = false
}

resource "aws_iam_role" "this" {
  name               = "staging_reporter"
  assume_role_policy = jsonencode({
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Principal": {
                "Service": "lambda.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
  })
}

Kosli report command

• The Kosli cli report command that is executed inside the Reporter Lambda function can be obtained by accessing kosli_command module output.
• Optional Kosli cli parameters can be added to the command with the kosli_command_optional_parameters module parameter.

module "lambda_reporter" {
  source  = "kosli-dev/kosli-reporter/aws"
  version = "0.5.0"

  name                              = "staging_app"
  kosli_environment_type            = "lambda"
  kosli_cli_version                 = "v2.7.8"
  kosli_environment_name            = "staging"
  kosli_org                         = "my-organisation"
  reported_aws_resource_name        = "my-lambda-function" # use a comma-separated list of function names to report multiple functions
}

output "kosli_command" {
  value = module.lambda_reporter.kosli_command
}

Terraform output:

Outputs:

kosli_command = "kosli snapshot lambda staging --function-names my-lambda-function"
