Basic Authentication password hashing

What did you do? I’m currently trying to set up a node_exporter on a test server using both TLS and basic authentication. I have setup a simple user in my playbook as mentioned in the README.

node_exporter_basic_auth_users:
   user: password

But this results in the following config file on the remote machine:

basic_auth_users:
  user: *0

Changing the password to something else does not affect the *0 field.

The following error is also raised when the node_exporter is starting up: level=error ts=2020-10-14T13:31:20.226Z caller=node_exporter.go:194 err="yaml: unknown anchor '0' referenced"

The exporter works well if no users are specified. Any idea where I could have made a mistake?

Did you expect to see some different? No crash on start up and a correctly hashed password in the config file.

I seem to have fixed the issue 😃.

pip3 install passlib[bcrypt]

I do not see any mention/error regarding the missing package in the log though…

A note for myself: this should be run on your local machine (where you run ansible), not on the target host!
