4 years ago Opened this to guage interest in the idea. if accepted we can easily extend this to work for output also.
Example plan showing the two use cases (assuming the terraform state at the end):
plan terraform_lookup(){
## Show how to index into a specific value
$path_example = {
'_plugin' => 'task',
'task' => 'terraform::tfstate_lookup',
'parameters' => {
'dir' => '/home/cas/working_dir/dynamic-inventory-demo',
'resource_type' => 'docker_container.sshd',
'attribute_path' => '0.ports.0.ip'
}
}
$path_example_output = resolve_references($path_example)
out::message(String($path_example_output))
## Show how to just read data for all resources that match
$match_example = {
'_plugin' => 'task',
'task' => 'terraform::tfstate_lookup',
'parameters' => {
'dir' => '/home/cas/working_dir/dynamic-inventory-demo',
'resource_type' => 'docker_container.sshd'
}
}
$match_example_output = resolve_references($match_example)
out::message(String($match_example_output))
}output:

This commit shows a general idea for adding a task based lookup plugin. Generally if a specific value is needed from a resource or if you want a list of attributes for a given resource this task allows you to look that up.
