#!/usr/bin/env sh

# Runs `go build` with flags configured for docker distribution. All
# it does differently from `go build` is burn git commit and version
# information into the binaries inside docker, so that we can track down user
# issues.

# WARNING: Tailscale is not yet officially supported in Docker,
# Kubernetes, etc.
#
# It might work, but we don't regularly test it, and it's not as polished as
# our currently supported platforms. This is provided for people who know
# how Tailscale works and what they're doing.

# Our tracking bug for officially support container use cases is:
