For more information, see the online docs.

Authentication

Credentials for authenticating to available EFDs are held in a special file on disk. By default, this location is ~/.lsst/notebook_auth.yaml. The file must exist and must have 600 permissions set. To set the correct permissions execute the following command in a shell:

chmod 600 ~/.lsst/notebook_auth.yaml

The format of the file is a YAML dictionary of valid EFD names. Each EFD entry should contain the username, password, and host for the EFD. Currently, my file looks like this:

lab_efd:
  username: <user>
  password: <passwd>
  host: "test-influxdb-efd.lsst.codes"
summit_efd:
  username: <user>
  password: <passwd>
  host: "influxdb-summit-efd.lsst.codes"
