Create OVH API Credentials

To use the OVH integration with Cetmix Tower, you need to create OVH API credentials:

• Follow the official OVH documentation (https://docs.ovh.com/gb/en/api/first-steps/) for creating an application and generating API keys
• It’s recommended to create a dedicated application with appropriate permissions for Cetmix Tower
• Store your Application Key, Application Secret, and Consumer Key securely—you’ll need them in the next step

Configure OVH Secrets in Cetmix Tower

Create three secrets in Cetmix Tower to store your OVH credentials:

• Navigate to Cetmix Tower > Settings > Keys and Secrets
• Create a new Secret with:
  • Name: OVH Application Key
  • Reference: ovh_application_key
  • Key Type: Secret
• Enter your OVH Application Key in the Secret Value tab
• Similarly, create another Secret with:
  • Name: OVH Application Secret
  • Reference: ovh_application_secret
  • Key Type: Secret
• Enter your OVH Application Secret in the Secret Value tab
• Finally, create a Secret with:
  • Name: OVH Consumer Key
  • Reference: ovh_consumer_key
  • Key Type: Secret
• Enter your OVH Consumer Key in the Secret Value tab

Note: These secrets will be accessible as #!cxtower.secret.ovh_application_key!#, #!cxtower.secret.ovh_application_secret!#, and #!cxtower.secret.ovh_consumer_key!# in your commands.

Configure OVH Endpoint

Create a variable to define your OVH API endpoint (region):

• Navigate to Cetmix Tower > Settings > Variables
• Create a new Variable with:
  • Name: OVH Endpoint
  • Reference: ovh_endpoint
  • Type: String
• Set your OVH endpoint (e.g., ovh-eu, ovh-ca, ovh-us) as the value

Example of Cetmix Tower Python Command to Create DNS Records

• Navigate to Command Creation

  • Go to Cetmix Tower > Commands > Commands
  • Click the Create button

• Configure Command Settings

  • Set a descriptive Name (e.g., “List OVHcloud Instances”)
  • Leave Reference blank to generate automatically (or set a custom reference)
  • Select Action: “Execute Python code”
  • Set Access Level: Choose appropriate level (e.g., “Manager”)
  • Optional: Set Default Path if needed
  • Optional: Add Tags (e.g., “ovh”, “cloud”, “instance”) for better organization

• Add Required Variables

  • In the Variables tab, add the previously configured variable:
    • ovh_endpoint (e.g., “ovh-eu”)

• Add Required Secrets

  • In the Secrets field, add the previously configured secrets:
    • ovh_application_key
    • ovh_application_secret
    • ovh_consumer_key

• Write Python Code

  • Go to the Code tab
  • Enter the following Python code:

  # List OVHcloud instances using ovh API
   result = {"exit_code": 0, "message": None}
  
  client = ovh.Client(
   endpoint={{ ovh_endpoint }},
   application_key=#!cxtower.secret.ovh_application_key!#,
   application_secret=#!cxtower.secret.ovh_application_secret!#,
   consumer_key=#!cxtower.secret.ovh_consumer_key!#
  )
  
  # Required variables:
  # - domain_name: The main domain (e.g., "example.com")
  # - subdomain: The subdomain to create (e.g., "test")
  
  try:
    # Create a new subdomain by adding a DNS entry (A record as example)
    ip_address = "1.2.3.4"  # Replace with the desired IP address
    response = client.post(
       "/domain/zone/" + domain_name + "/record",
       fieldType="A",
       subDomain=subdomain,
       target=ip_address,
       ttl=3600
    )
    # Refresh the zone to apply changes
    client.post("/domain/zone/" + domain_name + "/refresh")
    result["message"] = "Subdomain '" + subdomain + "." + domain_name + "' created and DNS zone refreshed."
  except Exception as e:
    result["exit_code"] = 1
    result["message"] = "Error: " + str(e)
  

• Save the Command

  • Click the Save button to create the command

Running the OVHcloud Instance Command
