From 6ab6724e4c49ae7df5afda042a536e7a13dddf25 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Sun, 3 Jul 2022 14:34:29 +0300 Subject: feat(ops/modules): add module for receiving a depot replica This module sets up a user with an SSH key and permissions to receive a (pushed) replica of depot from Gerrit. This still needs appropriate configuration in Gerrit's replication plugin on the other end. This module has been enabled for sanduny. For now it does not (yet) configure git serving.
