#cloud-config
#
# This is an example file to configure an instance's trusted CA certificates
# system-wide for SSL/TLS trust establishment when the instance boots for the
# first time.
#
# Make sure that this file is valid yaml before starting instances.
# It should be passed as user-data when starting the instance.

ca-certs:
  # If present and set to True, the 'remove-defaults' parameter will remove
  # all the default trusted CA certificates that are normally shipped with
  # Ubuntu.
  # This is mainly for paranoid admins - most users will not need this
  # functionality.
  remove-defaults: true

# If present, the 'trusted' parameter should contain a certificate (or list
  # of certificates) to add to the system as trusted CA certificates.
  # Pay close attention to the YAML multiline list syntax.  The example shown
  # here is for a list of multiline certificates.
