Jenkins pipeline 怎么连接Vault_jenkinsfile withvault-CSDN博客

当你拥有了secret_id 和role_id，你就可以通过以下代码来进行连接：

VaultLoginByApprole(){
  role_id=$1
  secret_id=$2
  export VAULT_ADDR=your vault addr
  export VAULT_NAMESPACE=your namesapce
  export VAULT_TOKEN="$(vault write -ns '$ns' -field=token auth/approle/login role_id="$role_id" secret_id="$secret_id")"

}

Python实现

import subprocess
import os

def VaultLoginByApprole(role_id, secret_id):
    # Set environment variables
    os.environ['VAULT_ADDR'] = 'your vault addr'
    os.environ['VAULT_NAMESPACE'] = 'your namespace'
    
    # Run the vault write command and get the token
    command = f"vault write -ns {os.environ['VAULT_NAMESPACE']} -field=token auth/approle/login role_id={role_id} secret_id={secret_id}"
    output = subprocess.run(command.split(), capture_output=True, text=True)
    token = output.stdout.strip()
    
    # Set the VAULT_TOKEN environment variable
    os.environ['VAULT_TOKEN'] = token
    
 

import os
import hvac

def VaultLoginByApprole(role_id, secret_id):
    # Set environment variables
    os.environ['VAULT_ADDR'] = 'your_vault_addr'
    os.environ['VAULT_NAMESPACE'] = 'your_namespace'

    # Create a Vault client
    client = hvac.Client()
    
    # Login using AppRole
    response = client.auth_approle(role_id, secret_id)
    
    # Extract the token from the response
    token = response['auth']['client_token']

    # Set the VAULT_TOKEN environment variable
    os.environ['VAULT_TOKEN'] = token
