✅ Ok: file_from_template_options_${destination}_ok
- ☑️ Already compliant: file_from_template_options_${destination}_kept
- 🟨 Repaired: file_from_template_options_${destination}_repaired
❌ Error: file_from_template_options_${destination}_error

Example

method: file_from_template_options

Documentation

The file_from_template method renders a template into a destination file using one of the supported template engines.

Template Rendering:

Renders a template using the specified engine (minijinja, mustache, or jinja2) into the file given in destination.

Data Sources:

If data is provided, the template will only use those data to render the template. The agent datastate will not be passed to the templating engine.
If data is not provided, the agent datastate is used instead (containing the existing variables and classes of the current agent run).

Template Source:

template_string: Inline template string.
template_path: Path to an external template file.
These two options are mutually exclusive — exactly one must be used.

Show Content:

If show_content: true, the rendered file’s content will be dumped to the report.

Engines:

minijinja
- Aborts rendering if undefined variables are used. Custom filters can not be added but the agent comes with a great variety of builtin usable filters.
mustache
- Ignores undefined variables gracefully.
jinja2
- Aborts rendering if undefined variables are used.
- Requires python3-jinja2 to be installed.
- Not supported on Windows agents

Complete documentation for the different supported engines can be found here.

Examples

Inline template string

name: render_simple
method: file_from_template_options
params:
  destination: /tmp/render.txt
  engine: minijinja
  template_string: "{{foo}}"
  data: "{\"foo\": \"bar\"}"
  show_content: true

This renders the string bar into /tmp/render.txt and also outputs the content.

Template file with Mustache

name: render_from_file
method: file_from_template_options
params:
  destination: /tmp/result.txt
  engine: mustache
  template_path: ${resources_dir}/template.mustache
  data: "{\"user\": \"Alice\", \"role\": \"admin\"}"
  show_content: false

This renders the template.mustache template with provided JSON data and writes it to /tmp/result.txt.

Jinja2 with missing variables (will fail)

name: render_fail
method: file_from_template_options
params:
  destination: /tmp/fail.txt
  engine: jinja2
  template_string: "{{unknown}}"
  show_content: true

This will return an error since unknown is not defined in data or the agent context.
