by ADMIN 81 views

Introduction

Setting up the Vault addon is a crucial step in configuring the AppRole and Vault policy for client certificate issuance. However, a bug in the script vault_create_approle.sh can cause the setup process to fail. In this article, we will explore the issue of the missing supermq_clients_certs_issue.template.hcl file and provide a step-by-step guide to reproduce the problem.

What were you trying to achieve?

I was trying to set up the Vault addon by running the script vault_create_approle.sh to configure the AppRole and Vault policy for client certificate issuance. The script is designed to generate and write the policy file based on the supermq_clients_certs_issue.template.hcl template.

What are the expected results?

The expected result is that the script should successfully generate and write the policy file based on the supermq_clients_certs_issue.template.hcl template and continue the setup without any errors.

What are the received results?

However, I received the following error:

./docker/addons/vault/scripts/vault_create_approle.sh: line 51: /root/bluleap/supermq/docker/addons/vault/scripts/supermq_clients_certs_issue.template.hcl: No such file or directory

This happened because the file supermq_clients_certs_issue.template.hcl did not exist at the expected location. Only magistrala_clients_certs_issue.template.hcl was present.

Steps To Reproduce

To reproduce the issue, follow these steps:

  1. Clone the repository: Clone the repository and set up Vault using the provided instructions.
  2. Run the command: Run the command:
