I just wanted to add a note that
lookup('env', 'ENV_VAR') | default('foo')
returns an empty string if ENV_VAR is not defined in the environment, but
if you use
lookup('env', 'ENV_VAR') | default('foo', True)
then if ENV_VAR is not defined (in which case the env lookup plugin returns
an empty string), the second parameter to the default filter tells it to
treat any falsy value as undefined.
