ancientt

A tool to automate network testing tools, like iperf3, in dynamic environments such as Kubernetes and more to come dynamic environments.

Container Image available from:

• GHCR.io

Container Image Tags:

• main - Latest build of the main branch.
• vx.y.z - Tagged build of the application.

Features

TL;DR A network test tool, like iperf3 can be run in, e.g., Kubernetes, cluster from all-to-all Nodes.

• Run network tests with the following projects:
  • iperf3
  • PingParsing
  • Soon more tools will be available as well, see GitHub Issues with "testers" Label.
• Tests can be run through the following "runners":
  • Ansible (an inventory file is needed)
  • Kubernetes (a kubeconfig connected to a cluster)
• Results of the network tests can be output in different formats:
  • CSV
  • Dump (uses pp.Sprint() (GitHub k0kubun/pp, pretty print library))
  • Excel files (Excelize)
  • go-chart Charts (WIP)
  • MySQL
  • SQLite

Usage

Either build (go get), download the Ancientt executable from the GitHub release page or use the Container image.

A config file containing test definitions must be given by flag --testdefinition (or short flag -c) or named testdefinition.yaml in the current directory.

Below command will try loading your-testdefinitions.yaml as the test definitions config:

$ ancientt --testdefinition your-testdefinitions.yaml
# You can also use the short flag `-c` instead of `--testdefinition`
# and also with `-y` run the tests immediately
$ ancientt -c your-testdefinitions.yaml -y

Goals of this Project

• A bit like Prometheus blackbox exporter which contains "definitions" for probes. The "tests" would be pluggable through a Golang interface.
• "Runner" interface, e.g., for Kubernetes, Ansible, etc. The "runner" abstracts the "how it is run", e.g., for Kubernetes creates a Job, Ansible (download and) trigger a playbook to run the test.
• Store result data in different formats, e.g., CSV, excel, MySQL
  • Up for discussion: graph database (Dgraph) and / or TSDB support
• "Visualization" for humans, e.g., possibility to automatically draw "shiny" graphs from the results.

Development

Golang version: v1.17 or higher (tested with v1.17.6 on linux/amd64)

Creating Release

1. Add new entry for release to CHANGELOG.md.
2. Update VERSION with new version number.
3. git commit and git push both changes (e.g., version: update to VERSION_HERE).
4. Now create the git tag and push the tag git tag VERSION_HERE followed by git push --tags.

Dependencies

go mod is used to manage the dependencies.

Building

Quickest way to just get ancientt built is to run the following command:

go get -u github.com/cloudical-io/ancientt/cmd/ancientt
