Azure Credential Error When Adding to a Job Template via Ansible Tower CLI

1 minute read


Whilst I was working out how to automate Ansible Tower (AWX) using the tower-cli command line tool , I came across an error when trying to create a Job Template using a Microsoft Azure Resource Manager credential, and couldn’t find a solution anywhere online.

These were the steps I took leading up to the error:

  1. First, I created an AWX Project using the following code:
     tower-cli project create --name "Azure Project" --description "Azure Playbooks" --scm-type "manual" --local-path "azure-linux-vm" --organization "Default"
  2. An AWX Inventory was created for Azure, including a dynamically generated SSH key variable:
     tower-cli inventory create --name "Azure Inventory" --description "Azure Inventory" --organization "Default" --variables "ssh_public_key: \"$ssh_public_key\""
  3. An AWX Credential was created for Azure, using the Microsoft Azure Resource Manager credential type, and referencing an Azure credential file:
     tower-cli credential create --name "Azure Credential" --description "Azure Credential" --organization "Default" --credential-type "Microsoft Azure Resource Manager" --inputs "@$azure_credential_file_path"
  4. Lastly, I tried to create an AWX Job Template for Azure, referencing the previously created resources:
     tower-cli job_template create --name "Azure Resource Group" --description "Azure Resource Group - Job Template" --inventory "Azure Inventory" --project "Azure Project" --playbook "resource_group.yml" --credential "Azure Credential"

After the last step was actioned, I got the following error:

Error: The Tower server claims it was sent a bad request.

Params: None
Data: {"job_type": "run", "playbook": "resource_group.yml", "description": "Azure Resource Group - Job Template", "inventory": 2, "credential": 2, "name": "Azure Resource Group", "project": 6}

Response: {"credential":["You must provide an SSH credential."]}


The workaround was to initially create the Job Template using the Demo Credential which uses the Machine credential type:

tower-cli job_template create --name "Azure CentOS Linux VM" --description "Azure CentOS Linux VM - Job Template" --inventory "Azure Inventory" --project "Azure Project" --playbook "centos_vm.yml" --credential "Demo Credential"

I was then able to add the Microsoft Azure Resource Manager credential to the new Job Template afterwards using:

tower-cli job_template associate_credential --job-template "Azure CentOS Linux VM" --credential "Azure Credential"
