Prerequisites and Assumptions

• Assumes you are using some sort of SSL terminating reverse proxy such as:
  • Traefik
  • Nginx
  • Caddy

Installation

Build from Source

Clone this repository and build the image with docker build -t (imagename) .

Prebuilt Images

Builds of the image are available on Docker Hub

docker pull docker.io/tiredofit/loki:(imagetag)

Builds of the image are also available on the Github Container Registry

docker pull ghcr.io/tiredofit/docker-loki:(imagetag)

The following image tags are available along with their tagged release based on what's written in the Changelog:

Configuration

Quick Start

• The quickest way to get started is using docker-compose. See the examples folder for a working docker-compose.yml that can be modified for development or production use.

Persistent Storage

The following directories should be mapped for persistent storage in order to utilize the container effectively.

Environment Variables

Base Images used

This image relies on an Alpine Linux base image that relies on an init system for added capabilities. Outgoing SMTP capabilities are handlded via msmtp. Individual container performance monitoring is performed by zabbix-agent. Additional tools include: bash,curl,less,logrotate, nano.

Be sure to view the following repositories to understand all the customizable options:

There are a huge amount of configuration variables and it is recommended that you get comfortable for a few hours with the loki::NG Documentation

You will eventually based on your usage case switch over to SETUP_TYPE=MANUAL and edit your own loki-ng.ini. While I've tried to make this as easy to use as possible, once in production you'll find much better success with large implementations with this approach.

By Default this image is ready to run out of the box, without having to alter any of the settings with the exception of the _HOSTNAME vars. You can also change the majority of these settings from within the Manager. There are instances where these variables would want to be set if you are running multiple handlers or need to enforce a Global Setting for one specific installation.

Networking

The following ports are exposed.

Maintenance

Shell Access

For debugging and maintenance purposes you may want access the containers shell.

bash docker exec -it (whatever your container name is) bash
