Question 1

How to load custom Jinja2 filters in TD4A?

Accepted Answer

Use the -f command-line option to specify a directory containing custom filter plugins, or mount it as a volume in Docker. The README provides examples for both CLI and container deployments, ensuring seamless integration with project-specific filters.

Question 2

Can TD4A work with Ansible dynamic inventories?

Accepted Answer

Yes, it supports loading Ansible inventories via the -i option, including dynamic ones with environment variables. This allows using real inventory data for template rendering, as shown in the podman run examples with -e flags.

Question 3

TD4A vs other template testing tools like jinja2-cli?

Accepted Answer

TD4A stands out with its visual, web-based interface and Ansible integration, whereas jinja2-cli is command-line only. Choose TD4A for interactive debugging and Ansible workflows, but opt for CLI tools if you prefer lightweight, scriptable environments without a browser.

Question 4

Does TD4A support JSON schema validation?

Accepted Answer

Yes, it has a dedicated 'schema' mode for building and validating JSON schemas alongside template rendering. This dual functionality is enabled via the -m command-line switch, making it useful for data structure validation in automation projects.

Question 5

How to set up CouchDB storage in TD4A?

Accepted Answer

Set environment variables like COUCH_URL, COUCH_USERNAME, and COUCH_PASSWORD, then run TD4A with those configured. The README details this for both Docker and CLI, but requires a pre-existing CouchDB database, adding setup complexity.

Question 6

Is TD4A compatible with Ansible 2.10 or later?

Accepted Answer

No, it's based on Ansible 2.9.12 filter plugins, so newer Ansible features might not be supported. You'd need to check for updates or rely on custom filters to bridge gaps, which could limit functionality in modern Ansible environments.

Question 7

Can TD4A handle Ansible vault encrypted data?

Accepted Answer

Yes, it supports vault passwords via the -v option when loading inventories, as mentioned in the inventory integration examples. This allows secure handling of encrypted data within templates, aligning with Ansible security practices.
