⁠Custom Telegraf Docker Image for quix-samples

This Docker image is used primarily in the quix-samples⁠ repository. It is a custom build of Telegraf⁠, a popular server agent for collecting and reporting metrics. This image extends the official Telegraf image by adding a custom output plugin and configuration tailored to publish to Quix Cloud⁠.

⁠Image Details

⁠Build Process

The Dockerfile defines a multi-stage build process to compile a custom version of Telegraf with additional plugins.

1. Builder Stage:

   • Starts with a Golang Alpine image for a lightweight, compatible build environment.
   • Installs required dependencies (git and make).
   • Clones the official Telegraf repository from GitHub.
   • Copies custom plugin code into the outputs directory within Telegraf’s source.
   • Builds Telegraf, creating an executable with the added plugin.

2. Final Stage:

   • Starts with the official Telegraf image.
   • Copies the Telegraf binary with the custom plugin from the builder stage.
   • Adds a custom Telegraf configuration file (telegraf.conf).
   • Sets the default command to run Telegraf with the specified configuration.

⁠Key Components

• Custom Plugin: The outputs plugin added to Telegraf enables it to export metrics in ways specific to the requirements of the quix-samples environment.
• Configuration: telegraf.conf defines how metrics are collected, processed, and outputted. Modify this file to change data collection sources or output behaviors.
