From d4b9b8ff72958532804b70bbe600ad43b36d5f2e Mon Sep 17 00:00:00 2001 From: Matthias Pigulla Date: Fri, 24 Mar 2023 12:15:25 +0100 Subject: [PATCH] Stop adding GitHub SSH keys (#171) We need to fix the SSH keys shipped with this action: https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/ But, we have another issue (https://github.com/webfactory/ssh-agent/pull/108) with regards to host keys: On self-hosted runners which are not ephemeral the known_host file fills up with repeated entries, because every action run adds a new line with the same host keys. Also, on those machines, the old key will still be in the `known_hosts` file. IMHO this action should not be repsonsible for shipping SSH host keys, that's too much responsibility. This section in the code is a leftover from early days when GitHub provided runners did not include SSH keys at all. For a long time already, GH takes care of placing their SSH keys in their runner images. For self-hosted runners, those people setting up the runner should fetch and verify SSH keys themselves and put it into the `known_hosts` file. I know this is a breaking change and is going to annoy users. But on the other hand, there is no better opportunity to drop this feature than with an emergency-style key revocation as today. Closes #106, closes #129, closes #169, closes #170, closes #172. --- README.md | 2 +- dist/cleanup.js | 57 +++++++++++++++++++++++++++----------------- dist/index.js | 63 ++++++++++++++++++++++++++++--------------------- index.js | 6 ----- 4 files changed, 73 insertions(+), 55 deletions(-) diff --git a/README.md b/README.md index fdf936f..46c74a5 100644 --- a/README.md +++ b/README.md @@ -272,4 +272,4 @@ developer looking for new challenges, we'd like to hear from you! - - -Copyright 2019 – 2022 webfactory GmbH, Bonn.
