+# awscli module
+This module executes awscli. Json output goes through base64 encode and decode to work around 
+terraform map of string requirements for external data.
+
+## Example root module
+```hcl
+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
+}
+```
+
+Sample output
+```
+Outputs:
+
+awscli_output = [
+  "i-0cd5e682bc68dbcd2",
+  "i-050d4adeafaa53cd0",
+  "i-008328e9dfb56b883",
