Create a variable with the Ansible Vault Password
Ansible has a feature called vault that lets you encrypt/decrypt files to secure the contents. This is useful for storing sensitive information, such as credentials, in a file.
While still in the CI/CD variables section, create a second variable with a key of ANSIBLE_VAULT_PASSWORD and we will provide you with the value of the variable for the Value field. Select the Masked button, unselect the Protect variable box and select Add variable.
