Loki Ansible Role

loki is a log aggregation system designed to store and query logs from all your applications and infrastructure. This role helps you to set up loki:

• with everything run in Docker containers
• powered by the official loki container image

Installing

To configure and install loki on your own server(s), you should use a playbook like Mother of all self-hosting or write your own.

Configuration

To enable this service, add the following configuration to your vars.yml file and re-run the installation process:

########################################################################
#                                                                      #
# loki                                                                 #
#                                                                      #
########################################################################

loki_enabled: true

########################################################################
#                                                                      #
# /loki                                                                #
#                                                                      #
########################################################################

Exposing the web interface

By setting a hostname you will expose loki on this domain. Usually you should also set up basic_auth in this case, otherwise everyone will be able to access your metrics

loki_hostname: loki.example.org

# Uncomment following lines to add basic auth
#loki_container_labels_metrics_middleware_basic_auth_enabled: true
#loki_container_labels_metrics_middleware_basic_auth_users : '<user>:<hashed_password>'

Usage

After installing, refer to the official documentation to send logs throught loki's API without an agent. The Promtail agent is coming soon
