terraform password generator

No time for a novel? Here are my my Cloud Architect field notes: Distilling my complex cloud adventures into digestible TL;DRs.

Then I wrote the code below which later re-use in the VM creation module

variable "length" { description = "The length input from the user" type = number default = 18 } resource "random_password" "password" { length = var.length special = true override_special = "!#$%&*()-_=+[]{}<>:?" keepers = { # this will recreate the password if the timestamp changes: meaning every running will generate a new password timestamp = "${timestamp()}" } } output "espassword" { value = random_password.password.result sensitive = true } /* Create a random password with the following requirements: - Length: 18 default value to change the length, use the following command export TF_VAR_length=20 in the shell changing the lenght will regenerate the password Can also be done using the following command: terraform apply -var 'length=20' -auto-approve - Special characters: !#$%&*()-_=+[]{}<>:? - Output the password as a sensitive output to show the password in the Terraform output terraform output espassword to regenerate the password terraform taint random_password.password terraform apply terraform output espassword */

To execute this code:

terraform init

terraform plan (optional)

terraform apply

terraform output espassword. This will show the password string in the console

Easier to execute all in 1 liner: terraform apply -auto-approve;terraform output espassword

Also, it's possible to create passwords of different length which can be specified at runtime, ex: terraform apply -var 'length=22' -auto-approve;terraform output espassword

Once that done the password will be show in the console, ex:

"w$5(sLht)N>!{IjQ7r" Note: Quotes are not meant to be part of the password
