Absolutely. In most cases, CredHub credentials are specified in YAML using a syntax
that looks very similar to that of a spruce operator. Unfortunately, this will cause
errors with spruce, as it thinks it found an unknown operator. To counter-act this,
just use the ((!...)) notation wherever you would use CredHub's ((...)) notation,
like this:
---
secret:
password: ((!from_credhub))
This will be ignored in spruce, and output ((!from_credhub)) as the value for
secret.password. When BOSH reads this in, it will handle dropping the ! for
you, and all will be well.
If you have an upstream template that you wish to use with spruce, you can
run a sed on them, to replace the ((...)) notation with ((!...)), and
they will be ready to use with spruce.
