This assumes you are familiar with the Python hvac client. If not, check out my article Hashicorp Vault - Getting Started with Python hvac.

If you have not yet installed Hashicorp Vault, check out my article Install Hashicorp Vault on Docker.

The very first thing you do after installing Hashicorp Vault is to initialize the vault.

• Initialize the vault using the vault operator init command
• Initialize the vault using the vault UI
• Initialize the vault using Python hvac (this article)

Replace vault.example.com with the hostname or IP address for your Hashicorp Vault. Here is how you can display the current initialization status of the Hashicorp Vault (true or false) and to then initialize the Hashicorp Vault if it is not initialized.

Check out my article Hashicorp Vault - Error Handling using Python hvac for details on how to include Error Handling.

#!/usr/bin/python3
import hvac 

client = hvac.Client(url='http://vault.example.com:8200')

init_status = client.sys.read_init_status()

print(f"init_status = {init_status['initialized']}")

if init_status['initialized'] == False:
  init_result = client.sys.initialize()

  print(f"root_token = {init_result['root_token']}")

  for key in init_result['keys']:
    print(f"key = {key}")

  for base64_key in init_result['keys_base64']:
    print(f"base64_key = {base64_key}")

Something like this should be returned if the Hashicorp Vault was initialized by this script.

init_status = False
