awscli module

This module executes awscli and returns the output.

input variables

Set the temp credentials if role switching is needed. Otherwise, leave them alone.

variable	type	required	description
access_key	string	no	for role switching
secret_key	string	no	for role switching
session_token	string	no	for role switching
aws_cli_commands	string	yes	command and parameters after aws

output variable

Normally terraform only produces a simple map of string in output. To work around this, awscli outout are base64 encoded. The output variable is then base64decoded back to the original text.

variable	type	description
awscli_output	string	output from awscli

Usage example

module "awscli_exec" {
  source = "../../modules/util/awscli"

  access_key       = module.as_role.temp_credential.AccessKeyId
  secret_key       = module.as_role.temp_credential.SecretAccessKey
  session_token    = module.as_role.temp_credential.SessionToken
  aws_cli_commands = "ec2 describe-instances --query Reservations[].Instances[].InstanceId"
}

output awscli_output {
  value = module.awscli_exec.awscliout
}
