history

Project history and usage

func-e is a Tetrate command-line tool for running Envoy. It downloads and selects Envoy versions, runs Envoy with a supplied configuration, and stores supporting data, logs, and runtime files under documented func-e directories.

Project history

The project presents itself as a small Envoy runner and version manager: install func-e, choose or resolve an Envoy build, and run it with a config file or inline YAML. Official releases show public versioned distribution beginning with v0.5.0 in July 2021, v1.0.0 in October 2021, and continued releases through the 1.x series.

Adoption history

func-e is distributed from GitHub releases, through its install script at func-e.io, Homebrew, and winget package facts. Its audience is Envoy and service-mesh users who want a repeatable local way to try Envoy versions or validate production configuration.

How it is used

The typical workflow is to run func-e with an Envoy config file or inline config, list available Envoy versions, select a version with func-e use, or override with ENVOY_PATH. It stores Envoy binaries under FUNC_E_DATA_HOME and logs under FUNC_E_STATE_HOME by default.

Why package nerds care

func-e is a useful package-manager case because it packages not Envoy itself but a resolver and launcher around Envoy. The documented XDG-like directory variables and override URLs make it friendly to reproducible local testing while still depending on external Envoy release metadata.
