From 93aca81c1cb20695d010766042a3abbe820364e8 Mon Sep 17 00:00:00 2001 From: Kristoffer Dalby Date: Thu, 5 Jan 2023 12:44:28 +0100 Subject: [PATCH] Read integration test config from Env This commit sets the Headscale config from env instead of file for integration tests, the main point is to make sure that when we add per test config, it properly replaces the config key and not append it or something similar.
